keith morrison (voiceover): his crimes were chilling. his crimes were bizarre. it's a little creepy to hear something like that. yes. very creepy. it might just be a scream. i felt so scared for her, for me, for all the women. chris malette: and i just about fell off my chair. brenda constantine: we were in that much danger and didn't even know it. detective: what would you be willing to give me today to help me move past you in this investigation? keith morrison (voiceover): it was january 2009. brenda constantine and her husband brian rogers and their three teenagers, two boys and a girl, spent the new year's holiday the way they always had-- a trip out of town and then back to their home in orleans, a middle class suburb in canada's capital city, ottawa. it's a very family oriented community, lots of young families still moving into orleans, lots of kids. but as you say, in a town which is very safe,

orleans seemed particularly safe. yeah, there was never a lot of crime. keith morrison (voiceover): that january, when brian and brenda got their brood home on a friday evening, the family house in orleans seemed exactly as they left it, though brian did notice something odd. our digital clock in our room on the left side of the bed was blinking. i thought that was kind of unusual, but didn't think much of it, i mean. sure, and then you went ahead and just continued? just carried on our lives. keith morrison (voiceover): and never dreamed-- why would they-- that their digital clock was blinking out a warning. two days passed, during which time their 15-year-old daughter lived out of the clothes in her suitcase, as teenagers sometimes do. then came sunday. she was taking a shower. she went into her room, and she went to her drawer. and that's when she discovered all of her underwear had been taken from the drawer. keith morrison (voiceover): so she told her parents. she's a teenager, and, you know, clothes are everywhere.

and i said, well, did you check-- the floor. --your laundry basket? did you check your suitcase? did you check the floor? said, no, mom, everything is gone. she sort of freaked out? yeah. keith morrison (voiceover): her parents said what parents say. brenda constantine: and i said, go up and look again. and so, she started to cry. said, no, everything is gone, everything. keith morrison (voiceover): but she did check again and found more things were missing. brenda constantine: she's running out, and she's crying, very upset. and then we realized-- there's something to it. --there's something weird going on here. keith morrison (voiceover): but what was going on? brian rogers: i went upstairs and looked and saw, sure enough, [inaudible] missing, right? and-- i immediately called the police. i called the police. and reported it. keith morrison (voiceover): although brenda and brian were worried enough to call the police, they weren't sure of the reception they'd get. i thought it was a joke. i thought there must have been kids playing a joke. keith morrison (voiceover): but the police did not think so. they were at the house in a matter of minutes. and they were all business. they spent five hours combing through the place, then came back the next day to take apart the family computer. did they find anything? both: no, they didn't find anything.

keith morrison (voiceover): not in the computer, but in their daughter's bedroom, disturbing discoveries. along with 50 pairs of missing underwear, a number of their daughter's bathing suits, dresses, tank tops had also vanished. they discovered the intruder had rifled through the family photo albums and removed pictures, but only those that showed their daughter. and those were, like-- vacation. --pictures, vacation pictures down in punta cana. so they were all beach pictures, bathing suit pictures. keith morrison (voiceover): and then, says brian, it got ugly. that's when they said they found some dna evidence on my daughter's dresser. that was a shock. that was the one that-- really weird. keith morrison (voiceover): investigators said the sample was consistent with dried semen. they found it on the top of the daughter's dresser, where the underwear had been stolen. all of that, along with the fact that no one else in the house reported anything missing, led investigators to issue the kind of warning no parent ever wants to hear. they told us that-- lock your doors. secure your house. --we have to be very careful. we have to watch our daughter.

they said she was targeted. it wasn't a random break-in. keith morrison (voiceover): targeted, not random? that was when the fear crawled in, and it affected their once comfortable lives. everything from this moment different. you take your safety for granted almost, and then all of a sudden, nothing you can do is really good enough. keith morrison (voiceover): after that, their daughter was never alone. brian and brenda put in a new alarm system and kept asking, who was it? who would do this? they tried to come to terms, too, with the other troubling news they learned from police, that theirs was by no means the only break-in of its kind in orleans. so they knew there was a pattern. that's a little creepy to hear something like that. yes. very creepy. keith morrison (voiceover): in fact, almost a dozen such break-ins had been reported in orleans in the past year. the police had issued a warning to residents in late 2008, though brian and brenda didn't know about it. now, officers told the couple of their biggest concern--

that the intruder, whoever he was, would escalate from stealing lingerie to more dangerous behavior. they were very concerned at the time about the escalation. keith morrison (voiceover): and rightly so, because in a matter of months, that's exactly what was going to happen. it was almost like he had a gun on my head that moment. keith morrison (voiceover): coming up. the drawer was open. and that's when i realized somebody had been in the house. keith morrison (voiceover): a woman living alone discovers she's not. and i was like, hold on! in three steps, i was up to where she was, and she was standing with her hands like this. keith morrison (voiceover): when "dateline" continues. still have moderate to severe ulcerative colitis... ...or crohn's disease symptoms after taking... ...a medication like humira or remicade? put them in check with rinvoq, a once-daily pill. when symptoms tried to take control, i got rapid relief with rinvoq. check.

and made sure she was never alone. she had a very restricted lifestyle after that. keith morrison (voiceover): their daughter coped in her own way. brenda constantine: we have a spare room, and she stayed in there. she slept with the light on, and she still does. keith morrison (voiceover): brenda and brian, eager to warn others about the threat, called a neighborhood meeting. but odd as it sounds, they say the police asked them to cancel it. their objective is to keep this man doing it because he's obviously very intelligent and knows exactly what he's doing. and they thought they had to catch him in the act. wait. wait a minute. using the neighborhood as bait? exactly. keith morrison (voiceover): the police were doing what they could without success. by november 2009, almost a year after the break-in at brenda and brian's home, the intruder was still out there. more than a dozen break-ins had been reported, many involving stolen underwear, shockingly high for this snug, safe neighborhood.

brenda and brian, now on nervous alert, could not stop wondering who. who? who could have done this? who did this? keith morrison (voiceover): a woman named anne marsan-cook and her friend, howard gray, began asking that same question, and lived in this lovely old farmhouse 150 miles away from brenda and brian. howard lived on the same busy highway, not far from the small city of belleville. november 17, 2009. late that afternoon, anne hurried home to change into party clothes. it was her birthday. she was heading to howard's place to celebrate. so i was really rushing. i was looking forward to go. keith morrison (voiceover): anne lived alone much of the time in this old place, and that suited her fine. she's a music teacher and artist. she wanted time and space to herself. anne marsan-cook: i like to have space, as my art grows with space. but did you feel insecure ever before?

i mean, did you lock your doors and windows? no. keith morrison (voiceover): anne's friend, howard gray, grew up down the road. 15 years ago, we didn't even take the keys out of the ignition of the cars. hmm. that's what i grew up with. that safe? well, you knew everybody. yeah. keith morrison (voiceover): back on that november day, when anne got up to her bedroom on the second floor, she looked in the mirror, thinking about what to wear. it was then she noticed something strange in the mirror's reflection-- a bedside table with a drawer open. so i looked at it, and i thought, mm. like, i didn't open this. keith morrison (voiceover): she looked at the other bedside table. the drawer was open. all my sex toys and-- i mean, some stuff was gone. and that's when i realized somebody had been in the house. keith morrison (voiceover): had to be a prank. had to be howard. he had a set of keys to her place because he often did handyman jobs there. she hopped in her car, drove the 200 yards to his house.

and she came right in and then said, are you playing a practical joke on me? no, so then she proceeded to tell me. and i jumped right in the car and followed right over behind her. keith morrison (voiceover): the two of them traipsed upstairs to anne's bedroom, discussed at length whether to report the missing sex toys to the belleville police. my words were, if we phoned the police, it would be nothing but gales of laughter. yeah. and my first reaction was to phone the police because somebody had been in the house, i mean. but then he said think about it. and so really, it was embarrassment. no! no, no, it's just-- no, there was no embarrassment. i-- we were just thinking the reality of what will happen if you phone. keith morrison (voiceover): they were also trying to decide if maybe they should be laughing, too. maybe it really was a joke. but if so, who could have been behind it? i was thinking, it's somebody that knows me. they'll come up in the morning, you know, maybe in the mailbox with a ha-ha-ha, or something like that. keith morrison (voiceover): there's a reason they recall that conversation in minute detail, a terrifying reason. but on this evening, they did not

know that yet, as they prepared to return to howard's house for the birthday party he was throwing her. and it was simply an excess of caution when he told her, bring her pajamas. i said to her, obviously, someone's been in the house. you're not staying alone tonight. keith morrison (voiceover): and-- this was important-- before they left, they locked anne's house up tight just in case. all we did was just went around all the windows and the doors and made sure everything. and she went in front of me, and i went behind her. and i double checked every one. keith morrison (voiceover): that night, they partied with friends, drank howard's homemade strawberry wine, made light of the bizarre theft. perhaps the new day would reveal the prankster. then, 7:45 next morning, they were back at the farmhouse. anne ran upstairs to her home office to do some photocopying. howard waited below. then he heard anne's terrified scream. i was like, hold on! you know, my work boots were still on. but in three steps, i was up where she was.

and she was standing with her hands like this. keith morrison (voiceover): standing and staring at the old desk computer she hadn't fired up for months, and the screen was glowing in the dim morning light, a message that shook anne marsan-cook to the core. i took it so personally. this is-- i knew someone was out there for me. and that was very, very scary. keith morrison (voiceover): coming up. howard gray: i said, anne, we locked that door last night. and she goes, yes. and i said, well, that door is open. keith morrison (voiceover): was anne's intruder also preying on other women? his crimes growing ever more depraved. it had to be one person. there cannot be that many evil person around. keith morrison (voiceover): when "dateline" continues. can neuriva support your brain health? mary. janet. hey! eddie. no! fraser. frank. frank. fred. how are you? support up to seven brain health indicators, including memory.

i was really, really scared. keith morrison (voiceover): it was november 2009. anne and her friend, howard, were standing at an upstairs hallway of her old farmhouse near belleville, ontario. they were staring at her computer screen. it was spooky. i'll have to-- it was the first time in my-- i mean, it was-- --in my life that the hair stood up on the back of my neck because it was a message directed-- personal. yeah. keith morrison (voiceover): and now they knew. the break-in the previous day, the theft of those sex toys was not a joke, not even a bad one. all that time last evening they'd stood right in this spot deciding-- a long discussion-- should they call the police or not. they'd figured the cops would just laugh, so they decided not to call. but after anne spent that night at howard's and returned home first thing in the morning, this is what greeted her on the computer screen. "go ahead and call the police," it said.

"i want to show the judge your really big dildos." eventually, anne would wonder about those typos, but just now, quite suddenly, she froze. it was almost like he had a gun on my head that moment. keith morrison (voiceover): this time, anne called 911. and as she and howard waited for the police to arrive, they came to a deeply disturbing conclusion. whoever wrote the message-- maybe some half literate crazy, judging from the typos-- must have been hiding in the house the evening before when they debated whether to report the theft. he was listening to us. the police can't prove that he was there-- but we know. --so we have no evidence that he was there. keith morrison (voiceover): they had been talking just outside anne's bedroom. down the hall in this closet, they say, they found evidence to support their chilling theory that the intruder had been hiding there. it was all upside down. yeah. so, you know, he had to be listening to tell a message like that. go ahead, phone the police. keith morrison (voiceover): and then

a second dreadful discovery-- they searched the house to see if anything else had been stolen. and in her bedroom, anne discovered all her underwear had disappeared. and that was sickening. keith morrison (voiceover): anne loved lingerie, owned more than 100 sets. all gone. oh, she was a basket case. she really was. i got her right downstairs. keith morrison (voiceover): only to make a third gut wrenching discovery. i said, anne, we locked that door last night. and she goes, yes. and i said, well, that door is open. and she goes, no, it's not. keith morrison (voiceover): but it was. and then the two of us looked at one another, and we started talking about the possibility that whoever was here let them self out. they had to. keith morrison (voiceover): the rest of that day passed in a blur. a police officer from the nearby city of belleville got to the house and got to work. keith morrison: they took it seriously. yeah, he did. he did because i took him right upstairs, and as soon as he walked in to the office

and looked at what was on the computer screen, he pulled up his mic, and he just said, get forensics out here right now. keith morrison (voiceover): that same day, amid the upset, anne and howard had a question for the belleville police. it was about a couple of disturbing incidents that had happened up the road in a speck of a place called tweed two months before, incidents more serious than what happened to her, incidents also directed against women alone at night. although tweed was only 20 minutes away, it was not policed by the belleville cops. we asked all of them, did they know anything about those? because i said, it has to be connected. and-- - you told the police this? oh, yes! yeah, and of course, how do you know about it? you know, we don't know anything about it. they didn't know about it? well, they didn't seem to, or they didn't want to let on to. keith morrison (voiceover): but anne was convinced the incidents were linked. they had to be. and it had to be one person. there cannot be that many evil person around. keith morrison (voiceover): she says she begged the detective handling her case, investigate a connection. i said, please, look into the tweed case.

i said, it has to be connected. keith morrison (voiceover): but then life took over, as life will. and anne let the matter drop. howard gray: i pestered her about phoning. but i was thinking, you know, they know their job. they will phone you. but nothing happened for them? no. my son was getting married. and, you know, like, there was a lot of things to do. you know, i was-- life was busy at the time. keith morrison (voiceover): but anne was right about what happened up the road in tiny tweed. a terrible threshold had been crossed. and then the second one, oh, god, everything just went haywire then. keith morrison (voiceover): coming up. i said, what's going on? somebody break in my house? no, sir, it's way more serious than that. keith morrison (voiceover): police close in on a suspect. he said, so you're gonna tell us why you did this? keith morrison (voiceover): when "dateline" continues. stay ahead of your child's moderate-to-severe eczema with dupixent as they welcome the feeling of touch with clearer skin and less itch.

larry has lived in tweed all his life, the last four decades on this lakeside lane called cosy cove. cosy cove is probably one of the most ideal places to live. you've got the whole lake as your backyard. keith morrison (voiceover): it was a safe place also, enviably so. we've never had a problem here with anything, never. keith morrison (voiceover): though there was one disturbing incident back in 2007, larry confessed. his daughter, chris, who lived nearby, was with her brother dave when she surprised an intruder in her home. chris heard a noise, and she says to dave, dave, there's somebody in the house. chris opens up the door and hears this guy running out the door, jumps over the fence, runs off into the woods, and my daughter right behind him. he took off too quick, and they couldn't catch him. keith morrison (voiceover): the intruder got away, and that was that, or so larry and his family thought. then came september 2009 and the events

that troubled anne marsan-cook. the first call came in at 3:15 am, september 17. a terrified young mother described how she'd been awakened by an intruder, blindfolded, tied up, stripped, and forced to pose for degrading pictures. after a couple of hours, the man left. and there are issues that would cause the police some concern. keith morrison (voiceover): craig ackley is a former fbi investigator and profiler. dateline nbc asked him to evaluate these cases. you have an individual taking pictures. mm-hmm. what does that say? it suggests that it's an individual who is playing out a fantasy. that is fantasy driven behavior. it also says it's probably somebody who would do it again. keith morrison (voiceover): and so, apparently, he did. 13 days later, another terrified call to the police in the early morning hours. once again, a woman alone had been blindfolded,

tied up, stripped, photographed. and then the intruder left. he clearly has engaged in sort of reconnaissance behavior of knowing the victim is alone, that he would have the opportunity to spend two to three hours with her without fear of somebody coming in. he's done some research. he has done some research, which shows planning. what happened would have been shocking anywhere, but it was doubly so here in tiny little tweed. two sex assaults on two women alone at night within days of each other, within blocks of each other. not rape, but terrifying and weird. two attacks that seem to bear the same signature, so two attacks and maybe just one attacker. keith morrison (voiceover): the ontario provincial police, the opp, responded to both assaults. and after the second sexual assault,

the opp began canvassing the neighbors. i was standing there. and they come over to me and wanted to know if you've seen anything or heard anything or know of anything going on. keith morrison (voiceover): larry says he had nothing to tell them. by now, the news of the two assaults was all over tweed and beyond. i remember saying to my guys, look, we have to get more on this. keith morrison (voiceover): chris malette was then the city editor of the intelligencer, the newspaper in the nearby city of belleville. and we were given nothing. we were told the investigation is ongoing. no further information will be released. keith morrison (voiceover): around cosy cove lane, the women were terrified. everybody was just scared to death of what was going on after the first woman was assaulted. and i think some of the girls did start maybe locking their doors and start to take the keys out of their ignition, take them in the house, things like that, and be a little more leery of what's going on outside. and then the second one, oh, god, everything just went haywire then. keith morrison (voiceover): everyone thought it had to be someone local, but who?

it was just a real mystery, who this could be. and nobody could find out who it was. keith morrison (voiceover): nobody, that is, until the day larry jones came home from a partridge hunt to find his house crawling with cops. so i said, what's going on? somebody break in my house? no, sir, it's way more serious than that. keith morrison (voiceover): and way more serious it was, as larry jones was about to learn. first, he was escorted into a cruiser by one of the officers. he says, well, we think you've had something to do with two sexual assaults down the road. keith morrison (voiceover): it was a shocker. larry jones, a 65-year-old grandfather and 44-year resident of tweed's idyllic cosy cove lane, was now a suspect in the double assaults. he said, so you gonna tell us why you did this? keith morrison (voiceover): but all larry jones wanted to know was this-- why him? the guy who loved to hunt and fish, how did he end up in the back of a cop car about to face an interrogation about the worst crimes to hit his neighborhood

in living memory? whatever lay ahead wouldn't be pretty. i couldn't not even believe that they would even think that. keith morrison (voiceover): coming up. a crime wave moves from depraved to deadly. that's when i found out she was murdered. what is it like to hear that? i was in shock, but how to describe that? keith morrison (voiceover): when "dateline" continues. upset stomach iberogast indigestion iberogast bloating iberogast thanks to a unique combination of herbs, iberogast helps relieve six digestive symptoms to help you feel better. six digestive symptoms. the power of nature. iberogast. ooo! our car's value went up! the power of nature. maybe we should track all our cars' value on carvana? we need more trackers! oh! i'm getting a value update! do you see which one is going off? how's it trackin'? some dips, some rises. now what?

keith morrison (voiceover): why were the cops so sure they had their man? because the second victim, larry's neighbor, had called to say she thought his voice matched that of her intruder. he said, you ever been in those houses? i said, well, the first house, i don't know where you're talking about. the second house, why, yes, i was in the house about three years ago. keith morrison (voiceover): larry says he was so shocked by the questions, it was all he could do to answer them. i could not even believe that they would even think that. keith morrison (voiceover): because if there was one thing larry jones knew without a doubt in the world, it was that he was innocent. he'd never sexually assaulted either woman. me of all people, who's lived here for 44 years, and after living here for 44 years on this road, i'm going to start raping and pillaging our single women on the road? it's just ridiculous. keith morrison (voiceover): larry gave the police dna samples and fingerprints. and he promised to return to the station for a lie detector test, which he did in due course, and which he says he aced. but that didn't mean larry jones got his old life

back or his reputation. i've always done everything honestly and truthfully. and then all you've done all your life is gone out the window? it's just not right. larry jones would eventually be cleared. and meanwhile police investigating that series of break-ins in brenda and brian's neighborhood in the ottawa suburb about 150 miles that way seemed no closer to nabbing their intruder. anne marsan-cook was trying to put her home invasion and that taunting computer message behind her. and still, no investigators were able to connect any of these crimes. but then, why should they, so far apart? and when something truly awful happened in a nearby town in that direction, again, nobody, nobody was able to think of any reason why there should be a link. keith morrison (voiceover): marie-france comeau was, by all accounts, vibrant and vivacious, a dedicated

consumer of great meals, new countries, the odd pretty dress. alain plante was captivated the moment he saw her. first thing that caught me is her smile, yes, because she has a beautiful smile. keith morrison (voiceover): sadly for him, she already had a boyfriend, so he waited. a year later, in the spring of 2004, she approached him. and he? well, he was done waiting. we started dating, and it went pretty well. it didn't take so long for me to move with her. keith morrison (voiceover): he took his two sons with him. keith morrison: so she essentially became a mother or-- alain plante: stepmother, yes. keith morrison: stepmother to your children. she did her job pretty well. what did you like about living with marie-france? basically, she was in love with life in general, yes. keith morrison (voiceover): both alain and marie-france were french-canadian. both came from military families. early on, she chose to make the military

her life, too, becoming what's called a traffic tech. it's the people who actually load the stuff on the aircraft and have to balance the weight of the aircraft. keith morrison (voiceover): she served in germany and dubai and afghanistan. then, in 2008, after more than a decade in the military, corporal marie-france comeau became a flight attendant with the 437 squadron, here at the sprawling canadian force's base in trenton. the base is just down the road from belleville and not far from tweed. and soon, corporal comeau was chosen to work the flights for canada's top leaders. keith morrison: she was happy. oh, yeah. she loved her job. keith morrison (voiceover): but it was also that year, after 4 and 1/2 years together, alain plante and marie-france comeau split up. he moved away. she stayed close to the base, living here in a town called brighton. they were apart, alain says, but still in close contact.

he remembers a conversation they had in late november 2009. she had just got back from india, japan, singapore. and she was telling me all those new countries she discovered and all the new meals she could taste. and it was fun. keith morrison (voiceover): it was their last conversation. three days later, november 25, 2009, corporal marie-france comeau's body was discovered in her home, lying on her bed. i was told on the 26th. keith morrison (voiceover): told only that she was dead, nothing more. and with a heavy heart and 100 questions, alain plante went to brighton to find out for himself what happened to the woman he still loved. horror awaited. and that's when i found out she was murdered in her house. what is it like to hear that? i was in shock, but how to describe that? keith morrison (voiceover): there were no words in any language, alain would learn.

comeau's murder had been brutal, a sexual homicide. former fbi investigator craig ackley examined this case at dateline's request. he had no role in the investigation. what was clear was that somebody had raped her, and somebody had killed her. and somebody had spent time in the home. which, again, in the dismal business of investigating this sort of thing, suggests it's an organized criminal, as opposed to a disorganized criminal. sure. it suggests somebody who spent some time planning the offense, understanding he had time to go into the house and spend whatever time he needed with the victim, which suggests reconnaissance activity. keith morrison (voiceover): at the base, cfb trenton, corporal comeau's grieving colleagues held a memorial service. even the base commander, colonel russell williams, got involved, sent a letter of condolence to her father. but who could have done this?

investigators were stumped, although they looked at anybody close to marie, anybody including alain plante. this one time, one policeman came to me and asked me for my dna. that's when i freaked out. and i had to explain to them that i wasn't even there. i was 4 and 1/2 hours from there. keith morrison (voiceover): alain cooperated with investigators, and he was cleared. and when the forensics people were finished in the house and the police handed over the keys, it was alain as marie's executor who had it cleaned and emptied. so i saw the crime scene, so. what was that like? you see blood on the wall. you see blood on the floor. it's like csi, but it's not csi. keith morrison (voiceover): he had to step outside for a cigarette to steady himself. and then he went back in, resolved to take care of marie-france comeau's last business on earth, and to laugh, in his broken-hearted way,

about the easygoing woman whose life he'd once shared. we got rid of all the civilian clothes. in every coat, every pants, she had money, just change and dollar bill. and so it made me laugh because that was marie. right there was marie. keith morrison (voiceover): anne marsan-cook and howard gray lived just 45 minutes drive from comeau's house. they heard about the murder on the news. they never connected it to anne's break-in or the tweed attacks, for that matter. no, absolutely none. it was, you know, she was military. keith morrison (voiceover): but that was before they knew what they know now. before another awful crime shook their community, only then would all these crimes be connected. only then would the perpetrator be unmasked in a story that would rock the nation. coming up. andy lloyd: a 27-year-old woman wouldn't leave behind her blackberry, her purse,

it's a small, tidy house by a field just outside belleville, faces a highway that runs right past anne marsan-cook's home and on into tweed. jess's car was parked outside. inside the house, her bed was made, and her personal stuff was still there. andy lloyd: a 27-year-old woman wouldn't leave behind her blackberry, her purse, her makeup, her wallet, her car, her car keys, her house keys. keith morrison (voiceover): they called everyone they could think of, learned she'd watched tv at a friend's house the night before. and when she'd left, she'd gone straight home, texting the friend at 10:36 pm to say she was home and going to bed. that was the last anyone heard from jess lloyd. the young woman who loved to yuk it up playing the video game, "guitar hero," the jess lloyd who had a ton of friends, but no current boyfriend, the sister who loved to crack wise with her older brother. you know, i'd call her a name, and she'd have a better one right there waiting.

keith morrison (voiceover): but where was she now? it was just a mystery, an absolute mystery. and nobody could come up with any answers. keith morrison (voiceover): they didn't wait long to call the police. she was reported to us missing at noon on the friday. keith morrison (voiceover): corey mcmullan was then chief of the belleville police service. and with the information that the family provided us, that we realized that it had the potential to be a very serious case. keith morrison (voiceover): when the police arrived, along with the forensics people, andy lloyd says he and his cousin went outside with police permission to scout the grounds around the house. no idea that what he was about to discover would not just break the case, but send a shockwave right across the country. the first thing, says andy, the footprints. andy lloyd: there was a couple of different ones in the backyard. keith morrison (voiceover): he called in to the cops working in the house. i just said there's footprints in the backyard. you might better go look at them. and instantly, they told us, well, stay away from them. keith morrison (voiceover): so andy and his cousins headed over to the field by jess's house,

took a walk around. and that's when they found them, the tire tracks, tire tracks where they shouldn't be. we saw them come right off the road. so then, instantly, we thought, there's been a strange vehicle next door. keith morrison (voiceover): andy says they went straight to the cops with this, too. and then the investigating officers were handed another clue from one of their own because the night before, about 9:30 pm, while jess lloyd was at that friend's house, an observant member of the belleville police force just happened to notice an suv parked in the field by her house. there was an officer who was on regular patrol and thought there was something suspicious. he's driving along highway 37 there. yeah, just driving along, yep. the truck was sitting in somebody's backyard? it was in a field. and the officer stopped and knocked on the door and checked the house, and nobody was home, and took detailed notes-- keith morrison: [inaudible] yeah, took detailed notes of the vehicle and carried on. but the officer's notes were not quite as complete

as they might have been. she left out some rather significant details-- the suv's make and its license number, though it may not have seemed so important at the time. after all, nobody was home. there was no evidence of any crime. so, imagine how it was when the officer learned that jessica lloyd was missing. obviously, it's upsetting. it's going to be upsetting to anyone, but this officer went above and beyond. and we're very proud of her. at what point after jessica lloyd went missing did she say, hey, i saw that suv? as soon as she became aware that jessica was missing from that residence, she immediately came forward with the information. keith morrison (voiceover): that weekend, andy lloyd was running on coffee and cigarettes and urgent help, out searching every day. andy lloyd: it was overwhelming how many people, just volunteers, who showed up. and there was police officers everywhere. keith morrison (voiceover): but no jessica. not a word, not a call, not a hint of her whereabouts.

chris malette, then with the local newspaper, the intelligencer. i remember what i was thinking at the time. i don't think this is going to end well. but, you know, there was always hope against hope that she had just taken off or if somebody did take her that would-- she could have come back because it was just not something that happened around here. keith morrison (voiceover): he couldn't know it then. no one could. but the mystery of jess lloyd's disappearance would be solved in a matter of days, her case and the other unsolved crimes, the marie-france comeau murder, the sex assault in tweed, the break-in at anne marsan-cook's place, and before that, at brenda and brian's orleans home, finally pulled into one horrific vortex. and the outcome would stun not just the small city of belleville and the communities around it, but a nation, coast to coast. chris malette: i was blown away. i just couldn't take it all in at first. andy lloyd: everybody was on edge, just waiting for good news to come through.

keith morrison (voiceover): it never came. reporter 1: her face posted across the country. reporter 2: the 27-year-old belleville woman went missing on the night-- keith morrison (voiceover): the story was all over the local news. i think for a span of several days, we had page one stories almost every day. keith morrison (voiceover): it never occurred to anyone at the paper, said malette, to link jess lloyd's disappearance to other unsolved crimes in the region, the two sex assaults in tweed or the murder of a military woman, corporal marie-france comeau, a short drive away in a place called brighton. we were thinking, ok, we're in a run of a bit of bad luck right here in this community right now. keith morrison (voiceover): the lloyd family didn't make the connection either, though andy says his sister was well aware of the sex assaults in nearby tweed. she even had a name for the man responsible. andy lloyd: his nickname around my sister and her friends was the tweed creeper. like, that's what they had called him.

you know, lock your doors. the tweed creeper will get you. keith morrison (voiceover): the belleville cops and other police forces declined to discuss details of the investigation into jessica lloyd's disappearance. but cory mcmullan, then chief of the belleville police service, said this much. her officers were scrutinizing links to other unsolved crimes in the region early on. because we had jessica reported missing to us and because it was unusual circumstances, we were dedicating as many resources as we could. and that includes looking at what's happening in your neighboring jurisdictions. and-- what was happening? and we were aware that there had been two serious crimes out in tweed against women, and that there was another situation in brighton where a woman was murdered. so that-- and that's not that far away? or it's just down the road. no, no, it's not too far away. it was enough that at the beginning, it's, let's make some contact and have some conversations and see if there's any potential connections. keith morrison (voiceover): but first, there was work to be done, starting with those clues

andy says he discovered outside jessica's house. there were three sets of footprints, one going toward the house, the other two, one smaller than the other, heading out of the house across the field. investigators quickly realized the smaller set was a likely match for jess lloyd's boots. and those tire tracks preserved in the field, the ones going offroad into the field, they soon nailed the tire type. they were toyos. because they had reports an suv had been parked in that field the night jess lloyd vanished, they could also narrow down the make of the vehicle. from the wheelbase, they figured out there was only three possible makes that this could have been. keith morrison (voiceover): only three makes-- a toyota 4runner, a jeep cherokee, or a nissan pathfinder. but which one? could they track it down? on thursday, february 4, a week after jess lloyd went missing, the police set up a roadblock on the busy highway

in front of her home, stopping cars. one officer chatting up the driver, another surreptitiously checking tire treads. afterwards, the police called andy. they'd made some discovery. they just said we found something that possibly could be very, very crucial. and that's all that we knew. keith morrison (voiceover): soon after, teams of officers went door knocking on the highway in front of the lloyd place. anne marsan-cook lived five miles down that very road. her friend, howard gray, had a place nearby. and that's how she and howard found themselves once again telling a couple of cops the story of anne's november break-in. when they came in to the door, then i said, ok, i don't know anything. but have i got a story for you guys that's got to be connected to this. keith morrison (voiceover): howard told the officers about anne's break-in, the underwear taken, sex toys stolen. he told them, too, that he and anne strongly believed her break-in was linked to those sex assaults

almost five months before in tweed. they got it. they got it. yes, they did. keith morrison (voiceover): now, anne was convinced her case was linked to jessica's disappearance. it had to be related. i mean, that's-- i felt so scared for her, for me, for all the women. keith morrison (voiceover): coming up, a suspect's identity is revealed-- they said his name, and i thought, oh, no. and then they explained his position and who he was. i said, oh. keith morrison (voiceover): --and shakes a nation to its core. everybody hit the ground running, saying, boys, this is the biggest story we're ever going to have. keith morrison (voiceover): when "dateline" continues. ♪♪ sonya earlene and marcia are among the thousands of real women living with metastatic breast cancer; doing what they love. and taking ibrance. ibrance with an aromatase inhibitor is for adults with hr+/her2- metastatic

she's no longer with us. keith morrison: the worst news possible. after running on empty for days, after trying to stay strong for his shattered family, andy absorbed the blow, was the family's stoic public face. at least, he said, they knew. i'm kind of glad that it didn't take forever and ever. keith morrison: the police didn't tell the lloyds all they knew, just that they had an unnamed suspect in custody. it wasn't until andy and his cousin turned on the radio the next day that they learned the identity of the suspect. they said his name, and i thought, oh, no. and then they explained his position and who he was. i said, oh. keith morrison: shock wasn't a big enough word. this was news that would explode like a bomb. this is the story of the century for us. and everybody hit the ground running, saying, boys, this is the biggest story we're ever going to have. keith morrison: it was winter dark when the break came, that police roadblock on the highway

out front of jess lloyd's house. investigators were hoping to find a set of tire tracks to match those found in the field by jess's house after she disappeared. it was a long shot, of course. and then, 6:57 pm, a nissan pathfinder, toyo tires, was pulled over for questioning. the officer approached the vehicle. asked to see the driver's license. had to have been a coincidence. the driver was canadian forces colonel russell williams heading home after a day at the nearby trenton air base. in fact, williams was based commander. trenton, the largest air base in canada. the man in the driver's seat was a celebrated, decorated military bigwig. reputation, impeccable. so they asked him a question or two and let him go on his way. but also, they put a tail on him just in case. but this guy couldn't be the suspect. not possible. lucy critch could have told them that.

critch is a retired sergeant who once worked for colonel williams. i've never seen colonel williams ever conduct himself unprofessionally or inappropriately. never. keith morrison: and those cops could have had absolute assurance of the colonel's character from the man who knew him about as well as anybody. there's three friends in my life that have been, you know, close friends and have gotten into my inner circle and come to know my family and that, and russ was one of them. as close as they get. yeah. as close as they get. keith morrison: jeff farquhar met russell williams when he was 19. it was the first day of college. toronto. they were assigned to the same residence, where jeff discovered he was living with a controlling neat freak. i started calling him a couple of names-- like what? --like drill sergeant and, you know, mother goose and that kind of thing. keith morrison: didn't last. before long, they were buddies, close buddies, who shared an offbeat sense of humor. russ was up to the hijinx that are associated

with residence life. like what? he introduced us to some of these things. jump out of closets. you know, scaring the bejeebies out of each other when you're sitting at your desk studying or if you'd just gone to bed. and looking back those, are all fond memories. you know, i've got a lot of fond memories of russ and his hijinx, and i participated right along with him. keith morrison: russ, he was called then, was the athlete, a dedicated jogger. he kept his room remarkably clean. folded his laundry just so. rarely talked about family. rarely visited them, either. his parents were divorced. and for a college kid, he was extraordinarily self-disciplined. obsessive, really. if i got him to come out for a beer and chicken wings, it was exactly two beers. i'd never seen him have more. never seen him intoxicated. and as soon as we got home, he'd take out the change out of his wallet, and he'd look and see how much he spent. keith morrison: when russ was dumped by his first big love, said jeff, he worried when his friend sought solace in endless screenings

of the movie "top gun." i was concerned when he kept going to this "top gun" movie because it was all about getting the girl back. keith morrison: getting the girl and flying the plane. so maybe it shouldn't have come as a surprise when after college, with an economics and political science degree in hand, russ confided he wanted to join the air force. there's no way i would have guessed he wanted to go into the military, knowing what he was studying. and in fact, when graduation came and i said to him, so what are you going to do now, russ, and he said, you know, i'm going to go into the air force, i was dumbfounded. i said, well, why the hell did you do all this? you did a pretty lofty degree, four-year degree at ut, and that's nothing to sneeze at, you know? and not that i'm putting the military down, but i just thought there was another route to get there, wasn't there, that may be a little easier. but he said, no, i really want to fly. keith morrison: and he did. joined the canadian forces in 1987. earned his wings in 1990.

and up he went. captain in '91. major in '99. lieutenant colonel in 2004. i would describe him as a great boss. keith morrison: lucy critch started working for williams in 2004. he was squadron commander then-- she, the squadron's loadmaster. i never, ever saw colonel williams upset. it was-- it was just very low-keyed, very even, and he was easily approachable. keith morrison: and not half-bad as a pilot. we didn't bump and jump when we landed. he knew his job, and he knew it well. keith morrison: by then, williams was flying canada's top leaders. in 2005, he ferried the queen of england around during her visit to canada. his buddy, jeff, was hugely impressed when he saw a few autographed pictures in william's office. when i pulled it off the wall, i said, are you kidding me? and i said, did you meet the queen? and he said, yeah, yeah. i met the queen.

so here i am, feeling like a goof because i'm making a big deal of it, and he's thinking, oh, it's just-- that's my job. keith morrison: just the sort of modesty that becomes a standout officer with an impeccable record and a big future. by 2007, williams was working for the commanding officer of the country's air force-- lieutenant general angus watt, now retired. he worked hard. he did his job well. he provided good advice, and he produced good staff work whenever i needed it. we wish you the very best for your lives together. keith morrison: but he had a life too. when jeff got married, russ williams was the emcee. when russ, himself, got married in 1991, a small affair in an art gallery, jeff was there to emcee for him. jeff liked his wife, mary elizabeth harriman, mary liz to friends. she was a classy lady. so very classy and intelligent and fun to be with too.

so i thought it was a good match. keith morrison: and over the years, jeff says, she clearly learned to laugh about her husband's obsessive behavior. jeff remembers going to their house one night for dinner. russ was taking our jackets at the front door. and i opened the closet door, and in there were all these jackets, mary liz's and russ's. and i swear to you, they were all lined up within about an inch of each other. and it was a thing of beauty. i thought i was in a men's shop or something. i just threw my jacket, and i said, oh, for god's sakes, you do it, you know? and mary liz laughed, and she said, i told you, jeff. you just let him do it. keith morrison: russ and mary liz gardened and golfed together. they didn't have kids. a cat instead, and a home in orleans. she worked long hours as a senior official at the heart and stroke foundation of canada. in 2004, after 13 years of marriage, russ and mary liz bought a second home by a lake in tweed. jeff was invited up immediately,

before the deal even closed. as he remembers it, russ was taking photos that day, as he did during almost every visit. jeff farquhar: boom. out came the camera. and he set it up on the tripod. and we had some self-portraits, i guess you call them, self-photos done. keith morrison: photography had been william's passion for decades. he loved to shoot landscapes and birds and then stored the lot meticulously. he showed the setup to jeff. well, i really felt i was in a well-organized photo lab or somebody's personal museum of photos. keith morrison: by 2009, as far as jeff could tell, though russ and his wife were increasingly living separate lives during the week, he at tweed, she at their other home, they seemed happy. it was two professionals - well, you know, it was-- keith morrison: --who went their different ways, but got together? and they both had careers pulling at them in different directions. but i think they made it work. keith morrison: then came the night when colonel williams was pulled over in that roadblock.

that night, for the first time, investigators began scrutinizing the decorated colonel. could he be their suspect, the man responsible for the disappearance of jessica lloyd? and what about the other crimes nearby? the murder of that military woman, marie-france comeau? the two sex assaults in tweed? could this man be responsible for those crimes? could this respected military leader be that monster? soon, the loved friend, the respected boss, the military man with the glittering resume would reveal his true self in a remarkable and disturbing encounter, cop and colonel, that would reverberate across the entire country. coming up. jim smyth: you ever been interviewed by the police in a-- in a room like this before? i have never been interviewed like this. keith morrison: on camera and under pressure, the colonel gets a chance to clear his name. can he? jim smyth: what would you be willing to give

but when they saw his uniform, mind-blowing. the man whose tire treads turned up beside jessica's house was colonel russell williams, commander of the country's largest air force base. they kept an eye on him for a few days, did their homework. and then they invited colonel williams to the police station for an interview. would he agree to come? he did. as you can see here, everything in this room is videotaped and audio taped. russell williams: check. jim smyth: you ever been interviewed by the police in a-- in a room like this before? i have never been interviewed like this. jim smyth: oh, no? keith morrison: williams sounds comfortable. his interrogator is detective sergeant jim smyth of the ontario provincial police. the detective tells the colonel about the continuing search for jessica lloyd. he is gracious, welcoming. jim smyth: all right. well, again, russell, i appreciate you coming in. an investigation like this, i mean, i'm sure you can appreciate it's been big news-- yeah. keith morrison: notice it's just russell,

not colonel williams. and that's why we're here on a sunday afternoon. sure. so again, i appreciate it. keith morrison: ex-profiler craig ackley has watched the tape of the interrogation. he is impressed. the first thing he does, the detective, he gives russell williams the respect that russell williams believes he deserves. but he also places himself at the same level as somebody that russell williams can respect. sure. in other words, he is not subservient. so i want to explain-- keith morrison: then the detective goes to work. tells williams the police are talking to him about two murders and two sexual assaults. it's a matter of proximity, they tell him. the murder of jess lloyd because the colonel drove past her house on his way to work most days. the murder of corporal marie-france comeau because she was williams's subordinate. and the two sexual assaults because both happened a short walk from the colonel's second home in tweed, a place he used during the week. whether williams knows it or not, the detective is following a playbook that has been

tweaked and tweaked again. jim smyth: because essentially, there is a connection between you and all four of those cases. would you agree? geographically-- - in that i-- jim smyth: --or-- --guess i drive past-- yes. i would-- jim smyth: yes. --have to say there is a connection. yeah. jim smyth: yeah. and-- keith morrison: now-- --that's why-- keith morrison: --the details. where was williams the day jessica lloyd was reported missing? friday, on the day, i was at home most of the time. most of the day, i had a sort of a stomach flu. jim smyth: ok. in ottawa or tweed? tweed. keith morrison: and now, to the murder of the corporal under williams's command. jim smyth: the day that marie-france comeau-- yep. jim smyth: do you remember how you found out? i do. yeah, i was sent an email-- well, as soon as the off staff on the base learned, they told me. jim smyth: ok. i can't remember what day of the week we're talking about, but yeah. no, i mean, obviously, one of your people gets killed, it gets your attention. so. jim smyth: absolutely.

yeah. [inaudible] jim smyth: and how did you know marie-france comeau. i'd only met her once. she was on a crew i was on just after i got to the base. jim smyth: ok. keith morrison: next, the detective asks williams again, politely, respectfully, for his dna. jim smyth: what would you be willing to give me today to help me move past you in this investigation? what do you need? jim smyth: well, would you be willing to supply things like fingerprints, blood samples-- - sure. jim smyth: --things like that? - yeah. jim smyth: ok. footwear impressions? yeah. jim smyth: ok. keith morrison: williams now sounds a little apprehensive. can i assume you're going to be discreet? jim smyth: it's possible. yeah. because, you know, this would have a very significant impact on the base if they thought you thought i did this. jim smyth: as a people-- keith morrison: the noose is tightening. jim smyth: --i'm concerned-- keith morrison: the detective offers williams an out. would there be some innocent explanation, he asks,

to connect him to those victimized women? jim smyth: is there any contact that you may have had with any of those four women that you may not want your wife to be aware of? anything like that that we should know about to try and explain why, if your dna is found, it would help us understand why it may be there? absolutely not. jim smyth: ok. keith morrison: not in the homes of the sex assault victims and not in the homes of the murder victims. jim smyth: have you ever visited marie-france comeau at her residence? no. jim smyth: ok. all right. so you're quite positive there would be no reason why your dna would be-- - absolutely. jim smyth: --in any of those three locations? ok. did you know jessica lloyd, even in passing, for any reason? no, i didn't hear her name till it was on the news. jim smyth: ok. keith morrison: now a big reveal from the detective. it's time to bring in the tire treads. williams has no idea the cops have them.

jim smyth: what kind of tires do you have on your pathfinder? i think-- i think they're toyo. jim smyth: yeah. i don't know the model. jim smyth: ok. i'll read this off to you. see if it rings a bell. ever heard of-- does toyo open country hts-- yeah, that sounds right. jim smyth: make any sense? yep. keith morrison: now, williams knows they've got something on him. craig ackley: there's no room for ambiguity in russell williams's world. what the detective does is he puts the information in a very structured, concrete, honest way because russell williams knows the facts better than anybody in the case. course. russell williams is a very intelligent man. he pauses before each and every response. he thinks things through. the detective allows him to do this. keith morrison: next, the detective gets an important denial from williams.

his pathfinder, with its toyo tires, has it ever been in that field? jim smyth: your pathfinder's wheelbase width is very, very close to the width of the-- of the tires that were left in that field. ok? do you have any recollection at all of being off that road? - no. i was not off the road. no. what he's doing is he's building. each fact that he presents builds on the fact before. and he allows russell williams to process each and every fact. keith morrison: and with each fact that is set before him, russell williams inches toward the abyss. he just doesn't know it yet. coming up. but this detective does. jim smyth: you and i both know that the unknown offender on marie-france comeau's body is going to be matched to you, quite possibly before the evening's over. keith morrison: when "dateline" continues.

have you spent much time thinking about that? keith morrison: as he sits in this bare room, officers are in his home in tiny tweed, searching for evidence. they're in the swank, newly renovated townhouse in ottawa that he and his wife have just moved into, a point that will soon make a difference. is there anything you can remember-- keith morrison: now, detective sergeant jim smyth lets williams know that mr. nice guy is done. the tone changes. but the problem is, russell, is every time i walk out of this room, there's another issue that comes up, ok? and it's not issues that point away from you. it's issues that point at you, ok? keith morrison: the detective has already let williams know the tire treads on his suv matched tire treads found in a field by jessica lloyd's house. he shows williams the boot prints found behind the house. it's obvious they match the prints of williams's boots, the very boots he is wearing in this interview room. jim smyth: your vehicle drove up the side of jessica lloyd's house. your boots walked to the back of jessica lloyd's house on the evening of the 28th and 29th

of january, ok? you want discretion. we need to have some honesty, ok, because this is-- this is getting out of control really fast, russell, ok, really, really fast. hm. jim smyth: this is getting beyond my control, all right? i came in here a few hours ago, and i called you the way i called your today because i wanted to give you the benefit of doubt. mm-hmm. jim smyth: but you and i both know you were at jessica lloyd's house, and i need to know why. keith morrison: williams is busted, but not yet ready to admit it. so smyth ratchets up the pressure. jim smyth: you and i both know that the unknown offender on marie-france comeau's body is going to be matched to you, quite possibly before the evening's over. keith morrison: he gives williams time to think.

jim smyth: your opportunity to take some control here and to have some explanation that anybody is going to believe is quickly expiring. mm-hmm. keith morrison: and then he turns up the heat again. jim smyth: russell. mm-hmm. jim smyth: listen to me for a second, ok? when that evidence comes in, when that dna match-- when that phone rings and somebody knocks on this door-- mm-hmm. jim smyth: --your credibility is gone, ok? because this is how credibility works, all right? and i know you're an intelligent person, and you probably don't need to hear this explanation, but i also know your mind is racing right now, ok? because i've sat across a lot of people in your position over the years. - mm-hmm. keith morrison: the detective plays to the colonel's self-image. jim smyth: imagine how people are going to view you, ok? if the truth comes out after the clear evidence is presented to you, when you finally go, ok, i'm screwed now--

mm-hmm. he gets to the point, building a constant theme of sort of doing the right thing. how do you want to be viewed here? keith morrison: craig ackley, the former fbi investigator and behavior analyst. i'm doing everything i can for you. how do you want to be viewed? how do you want to be viewed is the driving force of this man's life. it's hard to believe this is happening. jim smyth: why is that? why is it hard to believe? keith morrison: long silences now. williams is cornered. it's just-- it's just hard to believe. keith morrison: and then this. my only two immediate concerns from a perception perspective are what my wife must be going through right now-- jim smyth: yeah. --and the impact this is going to have on the canadian forces.

keith morrison: and one more thing. jim smyth: russ, what are you looking for? i'm concerned that they're tearing apart my wife's brand new house. jim smyth: so am i. but if nobody tells them what's there, what's not, they don't have any choice. keith morrison: the confession is coming. it's right around the corner. i want to minimize the impact on my wife. jim smyth: so do i. so how do we do that? jim smyth: well, you start by telling the truth. ok. jim smyth: ok. so where is she? keith morrison: here it comes. three little words. got a map? keith morrison: got a map. a map so he could show detectives where he dumped jessica lloyd's bound body.

four hours and 40 minutes after they sat down, williams has cracked, thanks to the skill of one patient, persistent detective. he allowed russell williams to arrive at the decision himself. he allowed russell williams to feel as if he had some control, even though he didn't. keith morrison: but williams was only getting started. he would talk for almost six more hours that night alone, spilling his guts, telling everything, directing the police to find troves of evidence in his homes-- bags and bags of women's underwear, tapes hidden in a piano in the tweed place, thousands of photographs he'd taken, evidence of his crimes stored on memory sticks in the ottawa home. i'll tell you where the memory stick cards are. jim smyth: where are they? some in the camera bag, which they would have found in my office. keith morrison: and late that very night, williams led investigators to the bound body

of jessica lloyd. he dumped it on a rural road near tweed. the formalities then. colonel russell williams, 46 years old, commander of canada's most important air force base, one of the military's best and brightest, would be charged with two murders and two sex assaults. and later, more charges. 82 lingerie break-ins and attempted break-ins in tweed, in the belleville area, and in orleans, the ottawa suburb where brenda and brian lived. williams and his wife had lived there too, just around the corner. but how did he do it? how did he live this incredible double life? it wasn't hard for investigators to figure it out because the evidence was all there, stored in the colonel's own computer. bizarre and ugly and unbelievable. coming up. on the job with a killer.

craig ackley: he's smiling. he's laughing. he's completely at ease. he didn't feel anxious over what he did. keith morrison: did the mask ever slip? when "dateline" continues. stay ahead of your child's moderate-to-severe eczema with dupixent as they welcome the feeling of touch with clearer skin and less itch. the #1 prescribed biologic by dermatologists and allergists helps heal their skin from within. severe allergic reactions can occur. get help right away for face, mouth, tongue or throat swelling, wheezing or trouble breathing. tell your doctor of new or worsening eye problems, like eye pain, vision changes, or blurred vision, joint aches and pain, or a parasitic infection. don't change or stop asthma or other medicines without talking to your doctor. ask your child's doctor about dupixent. mirajoy: the overwhelming relief after miralax® helps you “go” miralax® works naturally with the water in your body. putting you in a supernaturally good mood. miralax®: free your gut to free your mood.

to afghanistan and the nation's disaster relief flights to haiti after its earthquake. his friend, jeff farquhar, heard the news and threw up. couldn't be. can't be. couldn't be. it just didn't make any sense at all. keith morrison: but it was true. the friend he thought he knew had carefully, obsessively recorded his depraved double life on thousands of photographs. here he was, a highly regarded officer by day, a lingerie thief and worse, far worse, by night. you look at this individual and say, how could he lead this double life? keith morrison: craig ackley, former fbi agent. russell williams is somebody who everything he did was compartmentalized, was categorized-- not just in his behavior, but in his thoughts. keith morrison: williams's double life began in september, 2007, the lingerie raids, the first one

here in idyllic cosy cove lane in tweed. larry jones's home turf. and soon, larry jones's daughter's home nearby was broken into. she surprised the intruder. he ran not far because russell williams's second home was right there on cosy cove too, right next door to larry jones. once williams was arrested, police called larry's daughter, gave her the news. the whole family was astounded. no clue that that could be him. that's how much we trusted this guy next door. keith morrison: typically, williams told police, he would break in through an unlocked door or window. he'd head to the bedrooms, try on female underwear, photograph himself wearing it. he'd steal keepsakes, which he'd photograph later at home in meticulously ordered displays. in essence, russell williams was creating his own pornography collection

in which he was the star. keith morrison: that collection was buried in williams's computer in a complex file folder system, the lurid photos time and date-stamped, every offense logged, every location noted. and he could go back and look at it again and again. - and he-- - relive it. --would relive it over and over. as he's doing this, the fantasies become stronger and stronger, and the acting out has to escalate. because the tension is greater. the tension is greater. and so now, the risk-taking. part of russell williams's personality structure is one in which he adheres to rules, regulations. part of it is a feeling of powerlessness, even though he's in a position of great power. keith morrison: he'd worked the area near his tweed home for eight months with impunity. virtually all his break-ins had gone undetected. then williams turned to his other neighborhood here in orleans, where he lived with his hardworking wife.

in the spring of 2008, he committed the first of two dozen break-ins here. and again, some homeowners never knew they'd been burgled. but remember brenda constantine and brian rogers? they knew. williams broke into their house in january 2009. left his semen in their daughter's bedroom. this is now into an arena of showing you, i've been in your home. i can come in here any time that i want. it's just completely shocking and horrible. and you don't even want to think about it. keith morrison: then came july 2009. colonel russell williams took over the top job at canada's biggest air force base, in charge of some 3,000 people, cleared by all manner of security checks. by then, he'd broken into more than 40 different homes in orleans and tweed, some multiple times. occasionally, he'd enter a home stark naked. [music playing]

keith morrison: here's williams later that summer, presiding over one of the many ceremonies now part of his duties as the face of the base. so i understand that there are challenges. i congratulate the members of the squadron-- keith morrison: as he spoke, his secret behaviors were about to escalate to rape and murder. in september, williams flew a supply mission to a remote canadian forces base in the arctic with a local official. he returned to his tweed home on september 16. that night, he committed his first sexual assault. very impressive. keith morrison: the next day, he presided over a publicity stunt, a strong man hauling a huge plane across the tarmac, attempting to break a guinness world record. the belleville bulls have decided to dedicate the upcoming season to the men and women of 8 wing trenton. keith morrison: days later, he cheerfully fielded reporters' questions at a local hockey arena. yes. i think i'll have the opportunity to drop

the puck at the beginning. keith morrison: a week later, the second sexual assault, a neighbor three doors down. on october 29, the same day police hauled larry jones away for questioning about those sex assaults, williams was photographed at a book signing at the base. and two weeks after that, he broke into anne marsan-cook's farmhouse. left that taunting message on the computer urging her to call the cops. i would imagine, for russell williams, it was an ultimate feeling of power. probably quite exhilarating for him. i think that night, i was a target. and his crimes escalated. and he went from her house-- next was the murder. keith morrison: one week later, the murder of corporal marie-france comeau. she was williams's subordinate. he had access to her personnel file, her address, her schedule. the day marie-france comeau's body was discovered, williams was taking part in a lighthearted united way fundraiser called jail and bail,

charged with being too young to be a wing commander at 46. he took part in a mock arrest. he's smiling. he's laughing. he's completely at ease. he didn't feel anxious over what he did. keith morrison: as base commander, williams sent sincere condolences to comeau's grieving family. and then he welcomed santa to the base. january 2010, disaster relief operations sending aid to haiti after its earthquake. williams oversaw the effort. hosted canada's defense minister on a tour of the haitian-bound supplies. won praise for his handling of the whole thing. and days later, broke into jessica lloyd's house. took her back to his place in tweed. that's where he murdered her after hours of torture. and then left for work. left her body in his garage. while her body was lying in his garage, he drives to the air force base, gets into an airplane,

and flies it to california. i mean, how is that even possible? it's just a complete lack of anxiety in that sense because once that tension is reduced from acting out, he's fine. keith morrison: so what was to be done with such a man? canadians would find out soon enough. coming up. but will they ever find out the answer to this question? jim smyth: have you spent much time thinking about that? about why? jim smyth: yeah. keith morrison: could there possibly be an answer? when "dateline" continues. upset stomach iberogast indigestion iberogast bloating iberogast thanks to a unique combination of herbs, iberogast helps relieve six digestive symptoms to help you feel better. six digestive symptoms. the power of nature. iberogast. ooo! our car's value went up! the power of nature. maybe we should track all our cars' value on carvana?

msnbc. msnbc. >> when disgraced canadian military man russell williams went to court in the fall of 2010 for what was called a sentencing hearing, it was headline news across canada. he was brought to court each day handcuffed, head bowed. there was never any doubt about the outcome of this hearing. williams had decided to plead guilty to all 88 charges against him. there was never any doubt either about the sentence in a country with no death penalty. williams would be locked up for years and years to come. detective inspector chris nicholas of the ontario provincial police led the investigation and went to court each day. the nation's getting a good dose of reality, just how evil people can be. keith morrison: but there were those who had already had their dose of reality. it's still so hard to get around that fact

that, you know, that we were in that much danger and didn't even know it. keith morrison: evil had touched them. it's about being dirty, you know? just dirtied all over. keith morrison: and changed their lives forever. she tried to tell him, i'm a good person. let me live. he didn't listen. keith morrison: during the four-day hearing, the evidence was on display day after day, those pictures, that blank stare, the last pleading words of his victims. and on screens nationwide, that confession tape on which the killer recites his evil acts as if they were a trip to the grocery store. like what he did to jessica lloyd, even as she begged him. if i die, tell my mother. i love her. well, so i raped her in her house. and then i took her to the car and took her to tweed

and spent the day in tweed. and then i hit her as we were walking. she thought we were leaving. hit her on the back of the head. keith morrison: the murder of marie-france comeau. same matter-of-fact. same tone. russell williams: i subdued her. tied her up brought her upstairs and strangled her later in the morning-- well, more suffocated her with some tape. left her there. keith morrison: the details were horrific, how she fought back, how viciously he beat her before he raped her and, the final obscenity, videotaped her death.

what in heaven's name was he thinking? the detective tried to understand. jim smyth: well, i mean, let me ask you this. did you like or dislike these women? i didn't know any of them. jim smyth: ok. i met marie-france that one time in that-- in our airplane. jim smyth: ok. let's talk about jessica because she was there with you for the whole day, right? mm-hmm. jim smyth: what kind of feelings were you experiencing while you were with her that day? oh, she was a very nice girl. jim smyth: do you know why you killed her? well, i think i killed her because i knew that her story would be recognized because she knew i was taking pictures. jim smyth: mm-hmm. so because of the two stories in tweed, been quite obvious.

jim smyth: so if you didn't take pictures, what would you have done with her? i don't know. williams was given two life sentences to be served concurrently. no chance of parole for 25 years at least. and so they carted him off to prison. and finally, the canadian public could let it go. the russell williams horror story had finally come to an end, but not for everyone. jeff farquhar wanted answers. he was convinced something happened to push his old friend over the edge. perhaps it was something to do with the medications williams was taking. perhaps it was stress. jeff didn't contact his old buddy immediately after the story broke, but he did consider visiting him in jail. russ is still a friend of mine. and i hate the crimes, but i don't hate russ.

keith morrison: the canadian forces took care of some business after williams was sentenced. his commission was rescinded, a very big deal, and his uniform was burned. the former commanding officer of the air force, angus watt, says williams deserved it. we take our honor very seriously in the military, and he betrayed that honor so profoundly that i just don't see much room for most military people to forgive that betrayal. keith morrison: as for anne marsan-cook, she believes she was given a second chance. she and howard married in 2013. but she can't leave her past behind. i haven't written. i haven't painted. i haven't done anything. i'm just living day by day. and it will come back. i'm sure of that. no worries. but now i feel that if i-- if it comes out, it might just be a scream, a scream that goes on forever.

keith morrison: in the ottawa suburb of orleans, there's a new wariness, or so it seems. so many break-ins here. for brenda constantine and brian rogers, what matters now is telling their story so that no teenage girl is targeted, as theirs was. no child should have to go through that. hearing the story is one thing. but having experienced and lived it, that's another thing. and then hearing that he committed murder. he murdered two victims-- brian rogers: yeah. --after that. like, how horrible could that be? keith morrison: andy lloyd has his good days and bad. he still struggles with an evil he can't fathom and the question, why? i mean, she was my only sister, so i'll never have any nieces or nephews from my lloyd side, you know? i just-- i won't. keith morrison: alain plante thinks of his marie-france every day. russell williams stole from him too a wonderful woman and a hope he had. i always had the hope in the back of my head.

i was always hoping that she would come back one day to me. keith morrison: not now, not ever. the colonel, of course, claimed another victim during his murderous run-- his wife. mary elizabeth harriman has yet to speak publicly. it has been widely reported in canada she had no idea of her husband's double life. she filed for divorce after he pleaded guilty. as for the former colonel, he was sent first to canada's stately kingston penitentiary, later to a prison in quebec, locked away for years to come. so there will be time for russell williams, the man who ran the big, important base, to contemplate the question the detective asked him in that airless room. jim smyth: why do you think these things happen? i don't know. jim smyth: have you spent much time thinking about that? about why? jim smyth: yeah.

yeah. but i don't know the answers. and i'm pretty sure the answers don't matter. keith morrison: they may not to him, but for those who lost a sister, a daughter, a lover, a friend, for those he violated, for those whose peace he stole, the question will echo until the end of time. my moderate to severe crohn's symptoms kept me out of the picture. now i have skyrizi. ♪ i've got places to go and i'm feeling free. ♪ ♪ control of my crohn's means everything to me. ♪ ♪ control is everything to me.♪ and now i'm back in the picture. feel significant symptom relief at 4 weeks with skyrizi, including less abdominal pain and fewer bowel movements.
