>> ambulance, what's your emergency? >> my husband. i just came home from work. and i saw him collapsed on the bathroom floor. >> okay, is there has been awake? >> no he's not. i can't move him. he's wedged against the wall between the toilet and the door and everything. >> just stay on the lineman. >> i can't move him, he's not breathing. >> okay. >> i can tell, oh my god. >> by the time paramedics arrived, they confirmed what she had dreaded. her husband of nearly 40 years was dead. brigitte called bill's sister, liz galant. >> she did the whole thing of all you sitting down? what are you doing? are you sitting down? i said no. why. and she said something happened to bill. >> lives rush over to her brother's home. >> i don't think i believed anything until i saw the ambulance on the street. and the fire department, and the police. >> the pull police department was handling the case. an officer lent -- to bridget. >> she told me about not being

able to do cpr. her whole coming home, arrival, it was dark, she can find him at first. and then she found him in the locked bathroom. >> police had by now cordoned off the bathroom. and taken a statement from bridget. >> i don't remember either one of us paying panicking. we were calm and cool. no screaming, no crying. it was a strange behavior. >> after examining the body, the pathologist concluded that bill died from cardiac arrhythmia. in other words, his heart stopped. family and friends who are left with so many questions. for starters, at 64, bill was a fifth guy. >> and i remember thinking, this guy has got every type of health kick going. he makes smoothies every morning for him and his wife. he's so active. members of the why. plays basketball. what do you mean he died? and i'm thinking, is this one of those case scenarios that you read in the news?

the most fifth guy, they're running to k a day and then drops that of a heart attack? >> these things do happen. but the harrison's niece nicole, found it hard to grasp. >> absolute disbelief. >> and this is the man who is the picture of health. >> yeah, absolutely. there is just no way to understand that somebody like that just kills over and all of a sudden, is dead. >> it was also unbelievable to bridges brother, dog black bell. especially after he learned some odd details. like the fact that he was locked in the bathroom. despite being home, alone. >> what was he doing in the bathroom with the door locked? i don't know about your family. but if i'm the only man in the house, i am not going into the bathroom and locking the door. it just does not happen. that sort of, didn't seem right. and when brigitte said that she had to jimmy the door open? i, it did not make sense to me. >> and initially, it had been a

red flag for police to. they wondered if bill had purposely locked himself in there and died by suicide. but they ruled that out, and close the case. >> so then, a death makes sense? >> amanda triple death could make sense. it seemed odd. and it seemed weird that he was in the bathroom. it seemed weird that he was in the position that he was. >> but at the same time, what other explanation was there? >> we didn't know. >> were you satisfied moving on morning bill as a natural death? >> yes. brigitte asked me to do the eulogy. and there was no suspicion in my mind that it was anything less than god calling him home. >> but brigitte had doubts. an eerie sense that what happened the bill inside their home was not natural. she confided in close family friend, mike harrington. as they were driving together to bill's funeral. >> and i turn to bridget and i said, well, i guess we have lessons to learn here.

and she said what lessons do we have to learn here? bill was doing everything right. he did not die naturally. >> didn't you start to say who did it, and why? you just didn't get into that? >> it seemed that it was so out of left field. who in the world would want to harm this man? it just did not make any sense at all. >> brigitte shared similar suspicions with her brother, dog. >> what did you tell her when she had these thoughts? that something seemed a little suspicious? >> all i said was it could be bridget. i don't know. but nonetheless, brigitte had time to think about it. she mold on it. the rest of us are trying to support her. >> and it was a tough time for the grieving widow to say the least. not only was she dealing with her husband son and death. but her son caleb was serving an 18 month jail surfaced for the drinking and driving accident. >> it devastated her that her son is a prisoner.

and will only be allowed to come and view his father in his prison uniform. and then not be able to see anyone else. and not be able to hug him, support him. or he her. so they had to deal with this death individually. on the own. >> a few months later, caleb was released and back home with his mother. ready for a fresh start. his license had been suspended, so he couldn't drive. but his mom was there to take him to work and help with the children. >> she has her son home. the kids have their dad back. >> yes. >> so where things starting to get back to normal? >> i would say yes. except, we have the issue that's the buffer is gone. that bill is not there as the peacemaker. and, so of course, there is friction. >> between brigitte and caleb? they fought? >> not so much fought. but just, it wasn't that warm

and happy place that you want to walk into all the time. >> harrison's niece, kate, remember i christmas after the uncle bill died. how the house felt so very empty. >> of course it would never be the same again. we went through the emotions but we felt lost. >> but a few days later, and early spring 2010. she visited and brigitte again. it was around the one year mark after his passing. and the first wedding anniversary. >> i want to see her and the phone rang and it was someone looking for uncle bill. and, and brigitte just started to cry. she said i'm sorry, he has passed away. you can just see how raw her emotion was and how much she was suffering. it was heartbreaking. >> and there was more heartbreak to come in the house on pitch plank cross it. because just days after kate's visit, she received a harrowing phone call. >> i just imploded. i just, could not believe.

it just felt cursed. >> coming up! >> she was laying flat on the floor. with her head placed on the first step. >> a growing toll, and growing suspicion. >> it was even more traumatizing. there's a whole other level of disbelief. that something like that would have happened and it was shocking. >> this isn't a curse, this isn't a fluke. somebody's made up an action here. >> when dateline continues! n dateline continues

harrison. there was nothing that they could do to save her. she was gone. >> did you see anything that was consistent with a fall? >> the only thing that we saw was bruising around the throat area. but it was an assumption that maybe she could've fallen down the stairs. >> but bruising around the neck? doesn't that seem? >> doesn't sound consistent with the fall, no. the position that she was founded? could she have fallen down the stairs? heard her neck and then got in into the position for injuries? potentially. >> caleb got a call at work. rushed home to his son and began letting the family know. >> i get a phone call from caleb. saying. sit-down, brigitte is dead. my son found her at the bottom of the stairs when he came home from school. >> when he called me he said, i think they think that she has fallen down the stairs. >> the police had arrived and worked warning off the home. and they love the sister,

listeners, inside. >> caleb comes to me and says i could come in. and they had not moved the body so i could see her. >> still in the foyer, she realized she was standing just feet from where her brother died a year earlier. now, she was puzzled as she looked at brigitte's body. >> the first impression was that she had no phone. >> why did you think that? >> because of the position she was in. i think if you fall, you fall forward. unless you're catching yourself or something. but. she was laying back on the stairs. right near the bottom. it just didn't look like a fall down the stairs. >> let's called her daughter nicole. >> what is that moment like? getting that kind of news one year later that now year and has died? >> it was even more traumatizing. there's a whole other level of disbelieve that pick something like that would have happened. and it was shocking. >> no one in the family could

process the tragedy. >> how could this happen twice? in such a short period of time? to one family? >> i couldn't reconcile it. i thought maybe she had died of a broken heart. i had seen how devastated she was on their anniversary. >> miss kate blackwell had spent time with her and just days earlier. saw firsthand how the pain was still so raw. >> and i thought, maybe we it weekend her to the point that she slipped and her heart is shattered. >> when you say weekend? like her body was frail? >> possibly. not eating. not eating right. >> true, vigilant had been despondent since her husband's death. but nicole was skeptical that this was an accident. >> there was nothing believable about of perfectly help the person, having a catastrophic fall down carpeted steps. i don't buy it for a hot second. >> she and the other family

members could not help but think back to bill's sudden death one year earlier. the things that they have found unsettling at the time. >> it was just a monkey story. it seemed odd. and it seemed weird that he was in the bathroom. it seemed weird that he was in the position that he was. i think we try to live with this contradiction. and, needed to be there for caleb, for the kids, for bridget. >> now, the family push police to investigate both deaths. and the chief pathologist was concerned to. he wanted to exuma bills body to further examine his injuries. only it wasn't possible. his body had been cremated. >> and then the crime scene is gone? you can't go and re-examine a crime scene that doesn't exist anymore? >> that's right. >> or a body that doesn't exist anymore? >> given that your uncle was cremated? >> yes. >> it must be so frustrating. >> it must be frustrating because where a pretty regular family.

and we trusted that everything had been done. >> two deaths in one year inside the same home? the family was left with a horrifying possibility. >> this isn't occurs, this isn't a fluke. somebody is making an action here. but we didn't know who. >> somebody is out to get this family? >> guaranteed. >> coming up! >> he's not talking. he finds himself a hotel room. he doesn't want to talk about it. he is devastated by it. >> police calling caleb. one of the last people to see his mom alive. >> there was a mark on your mom's chin? >> yes. like this. >> was that from a fall or from something else? >> it wasn't like that in the morning. when she dropped me off. >> when dateline continues! when dateline continues attention military personnel, families

i have heard this stress killed, and it can just eat away your body. >> melissa had another theory. one a little more sinister. it had to do with caleb. >> when i was with caleb, i don't want to -- i've already been told by the detectives that fingers are being pointed, and i'm not, in any way, pointing fingers, because that's not why i'm here. but, when i was with caleb, he didn't have a good relationship with his mom. i'm not saying that is enough to do something to her, but he didn't have a great relationship with this mom. >> they say caleb might have even been violent to his mother. five years earlier, while still a couple, melissa reported, caleb attacked her in her home. later, he was convicted of domestic assault. it was the reason they separated, she said. >> he did some pretty serious stuff to me. i have heard of people, where their husbands assault them and it's just, you get an argument,

and they slapped, or hit you, or whatever. he wasn't like that. we got in an argument, he would not do anything until i turned my back, or went to bed. so, he would sneaky about the way he would assault me. so, i know that he has, in him, a tendency to do this. i know what he did to me, but i don't know. again, i don't know how she died, i don't know what she looked like, i don't know she was assaulted, i just don't know anything about that. i don't want to make assumptions to beat the halo they died, because i don't know. those things pop into your head, because i know my past with him, and i know what he's done, and what he's capable of doing. >> melissa's message was clear. she was suggesting that caeleb may be responsible for his mother's death. >> i assumed, i'm probably a little stronger of a person because of my age. when he assaulted me, i was in my mid twenties. that, compared to a 63 year old

woman. like i said, i'm not pointing fingers at him, you just asked, and that is all i've popped into my head. i wondered if. >> with chris buttery, they had been living together with caleb, and they had two children of their own. >> is there anything you can shed light on with respect to bridget? >> the thing that popped through my mind, if anything, was wrong. it was automatically killed. just from his background. i just thought, you know, maybe they had an argument, maybe he did something, i just don't know. i've never trusted him. i think he's violent. he has a violent past. >> caleb harrison, son in mourning, or, suspect? >> coming up -- >> you are going to look at everybody. it makes sense for them to look at kayla from that point of view. >> police had caleb in their

suspicious death of brigitte harrison. in autopsy, concluding she died of neck injuries. police did not know if she had taken a fall down the stairs, or if she had been murdered, inside of that same home, where her husband, died one year earlier. police have zeroed in on someone close to bridget. her son, caleb. >> their first suspect was caleb. that makes sense to me. >> caleb had a dark history, including a domestic assault, and drunk driving conviction. his estranged wife, melissa, suggested he might have harmed his mother. >> i know he has, in him, a tendency to harm people if they

pass him off. >> also, as an only child, he stood to gain life insurance, including the house. >> he is the mail in the house, he is the person who will benefit if you follow the money. he is the beneficiary. >> but the very idea of caleb hurting his mother was inconceivable to caleb's uncle, and a family friend, my carrington. >> were you aware that caleb had been looked at in his mother's death? >> i had heard that. i guess, you're going to look at everybody. it made sense for them to look at kayla from that point of view. it never came to mind, in my mind, that he would have any kind of involvement at all. it just didn't make sense, knowing caleb's character. >> did your mind ever go there? what if? what if caleb snapped? >> no. >> things were harder than we thought? >> no. it was not part of his nature. i had known the sky since he was six months old. >> he loved her. there was a complicated relationship, but he loved her.

he never hurt anyone like that. >> there was a suggestion that he might have wanted the life insurance, the money. >> no. no. no. and you don't want the money in lieu of the love of your parent. no. you don't. >> despite caleb's domestic assault conviction, they didn't believe melissa's allegations. >> i remember speaking with caleb, and not really understanding where these allegations would come from. >> what were they? >> she was claiming, there was abuse happening, but i was with them 90% of the time, or our children work together, and i'm not sure where any of these things would have occurred. there was never any evidence, i didn't see any evidence of anything happening. >> did you believe there was a chance she was telling the truth, that he was being abusive? >> absolutely not. >> when police checked caleb's whereabouts on the day his mother died, his story checked out. he was working, all day. >> they knew he could not have,

possibly, physically, have done it. he had an airtight, absolute alibi. they know it is not caleb. there is no way he could've, possibly, been involved in this death. so, then, i thought, well, now that you know it is not caleb, who do you think it is? >> the family wanted police to look at other people, but, from what they understood, police did not have any other suspects. with no solid evidence, like fingerprints, dna, or witnesses, police or stop. weeks past. >> you are in limbo, not knowing what's going on with your sister's investigation. >> in my opinion, they had focused on caleb being the culprit. so, rather than broadening the investigation as quickly as they should have, they intended to sit on it, hoping they would find something to break on

caleb. to prove, his alibi wasn't good. >> was a family saying to the police, come on? it's one year apart? we really suspect foul play? >> absolutely. the conversations were had. but, i don't think the family was ever satisfied with the amount of continuous investigation, we all felt, should have happened. >> what was the final thing they said? >> we will continue to investigate. >> the police did, for a while. in june, two months after brigitte's death, authorities concluded, there was no foul play. no forced entry, no signs of a struggle. the death was classified as undetermined. not long after, the police closed the case. >> the family was not informed that this was no longer being treated as a murder. as a homicide. and, yet, we had heard the police seem to inform us. i'm pretty sure if they had

told me that, i would remember it. >> brittani's brother, dog, says the family was kept in the dark. >> i don't know any other family member who says, yes, they told me they were into investigating it as a homicide. >> how could you forget? that would be one of the most critical moments of your life, hearing that, that your sister's investigation is done. >> yes. >> doug feared, he would never know what happened to his older sister. but, his bigger fear, now, was for caleb, and the children. there was a killer, stalking the family, and wanted them protected. >> you were, actually, worried that caleb would be next? >> absolutely. caleb says, i'm a big boy, i can take care of myself, and i said, caleb, you can step off the curb and get hit by a bus. the result is the same. let's, at least, drop a will, let's, at least, say who you want to raise the kids. >> caleb agreed, and eventually, he seemed to be getting on with his life.

by the summer of 2013, three years after his mom's death, caleb had a girlfriend, and was living in his childhood home, on pitch pine crescent. the home, were both of his parents had died. despite mistakes in his past, caleb was a devoted father to his two kids, ages ten, and 12. his friend, paulo, said that those kids were his world. >> what things did he like to do with his kids? >> he coached both in baseball. he would take his son paint balling. anything those kids wanted to do, caleb was up for. he was an exceptional father. he was a great father. >> they were there to support him as well. >> we had accepted that they passed away, in the next stages are for us to create a family, and a village, to help caleb raise these children. >> did cain up not fear for his life? did he not where he could be next? >> i can honestly tell you, he never said that to me. >> no one could have imagined

that this family would be faced with another, agonizing, loss. inside of that home, on pitch pine crescent. it was a summer day, august 23rd, 2013. in a toronto suburb, paulo's athena had just arrived at work. >> what is the first thing you do? >> turn my computer, on check my emails. >> caleb's good friend, paulo, preparing for a busy day at the company where they both worked. >> caleb and i were supposed to relabel the entire warehouse. as a minister passing, i hadn't heard anything. i got a little anxious. so, i texted him. >> caleb didn't text back. didn't pick up his phone. >> had he ever does not shown up for work? >> no he, had never not shown up. caleb, was also, fumbling his tech saying, he'd run behind, call in, he'd let somebody know. it was about 20 minutes where he was late. >> 20 minutes isn't that much.

>> it was for him. because, i mean, 30 seconds late, i'm calling you, telling about 30 seconds late. >> the guys in the office thought, maybe caleb was goofing off at home with his girlfriend. >> they said to me, when you drive by his house, and we will make fun of him for the rest of his life about it, because they're at home playing hooky? >> paulo drove over to caleb's. he rang the doorbell, and the cleaning lady answered. >> caleb hadn't shown up for work, to have you seen him? >> no, no, i haven't seen him. i don't know anything. >> okay. is he home? >> i don't know, i don't clean his room. maybe he's in his room. >> so, i said, okay. >> are you getting worried now? at this point? >> i'm puzzled at this point. >> she said, do you want to come inside? at that point i said, okay, and started walking up the stairs. i asked her what betterment was, and she pointed to the end of the hall. >> as paulo walked down the hall, he called caleb's name, over, and over. when he got to caleb's bedroom, the door was closed. >> coming up --

away in nova scotia. melissa was arrested for parental child abduction. the kids will return to live at their grandmothers house. >> she goes to get the kids and bring them home. must have been such a relief to get them back? >> oh yes. very very much. happy to have them back. >> then, in 2010. about a year about after bill that. melissa pleaded guilty and was going to be sentenced on the abduction charge. bridget was supposed to give a bridge or impacts story at the hearing. she never made. it she died at the bottom of the stairs. >> brigitte that is the day before the hearing. >> so that they would not have to go to court at that time. >> doug said, after brigitte died. he told police all about the fights over the children. >> i gave them the information that i thought that they needed. i'm just saying, look. there is only a couple of people in this world who it makes any sense to be involved with this. >> so he wanted police to talk to people connected to melissa.

>> who's angry with bridget and bill? it's them. go talk to them. find out what they were doing. to this. >> but he says his suspicions fell on deaf ears. then, three years later. in 2013, caleb was murdered. stephanie says the timing was no coincidence. >> melissa was asking to have the kids 50% of the time. caleb was reluctant to do that. >> the issue was never resolved. after his death, melissa was awarded full custody of their son in daughter. >> what are you thinking happened? >> i'm thinking absolutely that there was conspiracy between melissa and christopher. i had no doubt in my mind that this is the first third time. the first time was abducting the children, the second time was getting rid of that cold hearing with and brigitte and this third time was again, about the children. her mission was to get those children. and get them away from caleb so

she could carry on with her life. >> it took caleb's death, she says, for police to finally pay attention to what the family had been telling them for years. >> and now they're asking, give us some fast ground on melissa. what do you know about the children? all those questions are now coming to us. >> a clear motive was emerging? >> the motive that the police were pursuing is that they believed that the harrison's had been killed, potentially, over the custody battle. >> did it finally feel like redemption? that the police were listening to you? that they were doing something about? this >> it did. but for me personally, and i think the rest of our family. we just wanted to say, but why can't you arrest them now? >> police had no hard evidence to make an arrest. so, they were about to get creative. >> coming up! >> krista melissa had no idea what was going on under the noses? >> they had no idea that police were in their house, setting up these wiretaps.

[music playing] police were now investigating,

not just hit caleb's murder. but the possibility that his mother might have been murdered as well. >> evidence gathered through this inquiry, open new avenues of investigation into the death of brigitte harrison. >> at this time it was a investigation that the family had given. >> the peel police department was extremely good at keeping the family group informed. they had meetings, where we were called in and they said they are worried certain things that we can tell you, the certain things that we can't tell you. but, you know, take our word for it that we are on this. >> you felt confidence? >> i was very confident in their dedication to it. >> so it went from zero to 100? >> absolutely. guaranteed. >> police suspected melissa and

chris were behind caleb's murder. but needed hard evidence to make the case against them. so several days after caleb's murder, a police officer went to their house posing as a garbage collector and picked up their trash. they found a pair of running shoes. reporter, amy dempsey. >> was there anything suspicious about this in the moment? >> i think it was suspicious that these appeared to be new shoes. >> why would someone threw out a new pair of running shoes? some officers working the case happened to recognize them from walmart. >> so they went to the nearest walmart and they learned that there had only been one purchase of those shoes recently. the night before caleb was murdered. >> and that walmart was at the same plaza where chris and melissa told police they went after the ball game. the plaza where they said they bought food at the p2p and subway. and when the officers looked at the surveillance video, there

was chris buying those shoes! >> and not only that. they had a debit card purchase on chris's debit history for the exact amount of the shoes. >> oddly, in their interview. the country's bold never mentioned going into walmart to buy the shoes. which suggested they were trying to hide something. and, there was something else discovered in that trash. a pair of gloves. >> on the gloves? they found the dna of both chris and caleb. so, victim and suspect. >> this is now placing these two together in some form? >> yes. it was definitely strong evidence against chris. >> and police had even stronger evidence. chris's dna was found under caleb's fingernails. but remarkably, there was no arrest. >> why did they not arrest chris right away? was it about the dna match? >> i think that they held off because they wanted to build their case against melissa. they had pretty strong evidence

against chris and in caleb's death. but they did not have strong evidence against christian bridges death. and they did not have direct evidence against melissa. >> in september of 2013, a month after the murder, melissa and chris move the family to nova scotia once again. by now, the couple had six children. four of their own, and the two harrison's. the police kept a close watch on the family. as officers built their case. setting up what would turn out to be as elaborate staying. >> this is a really undercover operation? >> there really was. there was a lot of officers involved and they were pulling out all the stops at this point. >> and pizza that operation was a fictional character named, sue andrews. >> sue started emailing melissa. and, just offering help. saying that she was a woman of means who came from a group of ladies who like to help people

out when they were in distress. and, had heard about melissa and all her kids. and wanted to do what she could to help them out. >> did melissa buy this to? >> at first melissa was a little bit standoffish. but then they got to talking back and forth in emails, and, soo started offering gift cards for groceries and best buy. things that they needed. and, at the time, melissa and chris were in really need of money. >> so police are basically kept fishing melissa? >> yeah. police are trying to keep this connection between sue and melissa to see what can come of it. and one of the things that comes out of it is, they help them with rent in this house. the east coast of canada. >> and the gift kept coming. so gabe melissa and her family a free weekend at a music park. even played for teen tickets to get them there. but the weekend was a ruse. police wanted the family out of

the house so that they could move in and launch the final phase of their nova scotia takedown. >> while melissa and chris were at the amusement park for the weekend, police were in the house setting up wiretaps everywhere. >> krista melissa had no idea what was going on under their noses? >> they had no idea that police were in the house setting of these wiretaps. >> but even with the house bucked, police know that there was no guarantee that they would catch the couple saying something incriminating. >> because people who may have committed a crime don't just sit around talking about what they did in the past. especially when they're busy taking care of six children. >> police had yet another plan to try to prompt them to talk. with the wiretaps in place, they began sending melissa more emails. and this time they came from a person claiming to be a victim liaison's officer. who passed on tibbets a belt the murder investigation. >> it's strange because melissa

was a suspect at the time. but she and chris seemed to believe that they were getting these emails because they were the parents of caleb's children. and part of a greater victims family. >> so these emails were sent to get them talking? >> the emails were sent to get them talking. what >> did they start talking about? >> it got them talking about the case. police would often send the emails strategically, at times when the children were in bed because obviously they couldn't be talking about this when the children were awake. so the conversations were respired, often. and lead at night. >> some of the recordings were barely audible. police had to listen over and over. like in this conversation where the couple seemed worried about the investigation. >> what are you thinking? >> i'm just scared. >> police sent one email which mentioned that there was unknown dna under caleb's fingernails. that seemed to get chris talking about fighting with someone. was it caleb? >> he did grab me by my neck. >> and melissa appeared to

reassure him that not much of his dna would be left on caleb. >> even if, by chance, he did get you on the neck, by chance, that would be a miniscule amount. >> police are listening to these wiretaps. listening to the conversations day and night. >> and the wiretapped seemed to pay off. one night, what they heard chris say. that appeared to point to caleb's murder. >> i went in there, and the -- cower didn't fight. >> in another conversation, they appear to be talking about bridget's death. at one point, it sounds as if chris believed he had an ironclad alibi. >> you're gonna try to tell me, while i was out running errands the day that she died. i somehow got into bridget's house, and i killed her. and then i went on and carried on with my day. without acting weird? that's someone with no one criminal background was able to kill somebody and make it look like a natural death? >> police listened and for over

two months. pouring over hours and hours of conversations between melissa and chris. then, it was time to move. >> police felt that they had enough. that they were ready to move in and make an arrest. >> coming up! playing cat and mouse with an accused killer. >> the day that it happened, i was out running errands all day. >> you could not have killed bridget because you are running errands. >> i'm saying i didn't kill bridget because i didn't kill bridget. >> when dateline continues! when dateline continues atopic d under control? hide my skin? not me. because dupixent targets a root cause of eczema, it helps heal your skin from within, keeping you one step ahead of it. hide my skin? not me. and for kids ages 6 months and up that means clearer skin, and noticeably less itch. with dupixent, you can change how their skin looks and feels. and that's the kind of change you notice. hide my skin? not me. serious allergic reactions can occur that can be severe.

chris is nova scotia home for over two months. by january 2014, officers had enough for an arrest. they charge the couple with the murders of brigitte and caleb. the news was bittersweet for the house and family. >> you get word that they've been arrested. what's that moment like when

you get that phone call? >> overwhelming joy. but devastatingly upset that we were right. because it's just awful. awful to understand that we were right the whole time. >> hours after his arrest, chris was in and nova scotia police in stationed under interrogation. >> i'm here because of facts. facts of what we've had here. >> police presented all the evidence against him. >> including dna evidence? >> they had a dna, the recordings of the conversation with melissa. they put it all on the table, said this is what we've got. and he was at first defiant. >> defiant about dna? >> i'm telling you right now. your dna is under his fingernails. >> well then it, got there some other way because it wasn't for me. >> the fight about killing bridget. >> the day that it happened, i was out running errands all day. that doesn't put me anywhere near brigitte. >> you could not have killed

it began with an apology. >> i'm sorry i lied to you. and try to pull the wool over your eyes. i was just scared. i didn't like the cable of harrison. he was awful to my family. >> then, the words that police waited to hear. >> i killed bridget harrison and caleb harrison. >> how did you kill bridget? >> i knocked on her door. she opened the door. i pretended to have a letter to give to the children. she refuse the letter, so then i forced my way into the house and i attacked her. >> what did you do? >> i hitter a couple of times.

i then proceeded to squeeze her neck, until she stopped breathing and lay down the floor. >> was there a plan beforehand? >> i wouldn't say there was a plan. i just thought in the back of my mind, what if? and then, i don't know. i was just driving around, and found myself close to the area, and i just, and then i went and did it. >> as for caleb, chris says that he sneaked out in the middle of the night to kill him. >> melissa had no idea. i left and went there. >> he was wearing those shoes from walmart. and the back gloves. he used caleb's sons k to enter the house. >> i proceeded to go up to the bedroom. and i had him in the chest. and when he sprung up we began to struggle. i didn't speak to him. i just not them to the ground

and then proceeded to choke him. >> what did you hit him with? >> a baseball bat. >> the interrogation was a 13-hour marathon. but chris had finally come clean. >> it was a great outcome for police. especially given where they started when caleb died with two deaths from before that were essentially cold cases. >> after confessing, chris asked for something in return. he made a tearful appeal for melissa. >> i don't want anything bad to happen to melissa. i'm honestly telling you she did not know anything up till after caleb, when all the questions were starting to arise. and i got scared. and i thought i could convened in her. she didn't tell anybody probably because i tell astern out to. >> at the end, the detective stepped out of the room. then returned to ask one final question. >> we've talked about caleb.

pathologist in ontario wrote a report saying that what the autopsy actually showed was that bill had been assaulted before he died. >> remember, bill's family always had doubts that he hadn't heart attack. so to them, that report revealed one more infuriating blunder. when they believe had tragic consequences. if bill's 2009 autopsy showed that he had been assaulted, it would've triggered an investigation. and a killer might have been caught. >> where was the corner? where were the police? why else was this man in this position in the bathroom with these injuries. and, you know, things like marks around his throat? >> with this new conclusion,, prosecutors had enough to charge chris with the murder of bill harrison. they allege that chris killed him during a confrontation over the children. >> how do you feel when you learned that his death would be a part of this? trial? >> we lost everybody by 2015.
