>> a working mom murdered in the dark. >> it's hard to imagine that anyone would be capable of something like that. >> just 20 steps from her own front door.

happened in those 20 steps. >> it didn't make sense to me. >> the men in her life, all three, were there that deadly morning. you know you were a person of interest? >> we still love each other very much. >> somebody knew that we were seeing each other and didn't like it. >> whodunit? >> everybody was a suspect. >> my stomach was in my throat. >> all of us were taken aback. >> it was really hard for my brain to wrap around that. it was early morning. still dark, the spring air was a cold blanket around the pickup parked and running near the main street of little glendive, montana. at 5:20 the passenger side door opened, the woman stepped out, and hurried towards the entrance

her coat disheveled. her bra slung over one arm. the man's eyes followed her in the dark. drawn as other men's eyes were, like moths to a flame. to her, to the woman now crossing the sidewalk to her doorway, susie. lightning in the bottle. >> they were all there. >> there at susie's front door. >> each one of them was part that crime scene. >> but how many and who? who are the eyes in the dark sat started that awful cascade of events of terrible things? >> i just dropped the phone and cried and cried and cried. i just couldn't believe that that could happen three times in one family. sunlight in the bad lands of eastern montana is like nothing

that unsullied sky, the vast rolling prairies dotted sparsely with tiny old hamly s in which business is personal and where friends and families have worked the same places for generations. places like circle, population 600, susie's hometown. >> she livened things up a lot. >> this is her elder sister. it was nice to have that little breath of fresh air in the family because the rest of us were a little more quiet. >> susie was the fifth of six kids born to marlene and h husband jack, the county under sheriff. >> she loved the horses and she loved to go riding. go ridtng quite a bit. >> susie's love of horses grew as she did and shaped her work ethic. her sister-in-law. >> she was not afraid to be out there shoveling manure or fixing a fence.

>> but if there was one word most used to describe susie, it wasn't so much feisty as -- >> fun with a capital "f." >> she was very impulsive, so she didn't think a lot ahead. she just kind of went with the moment. >> and so when susie went off to a technical school three hours away in billings and got herself a boyfriend, perhaps what happened next shouldn't have come as a very big surprise. >> it was she's pregnant. you get married. that's just what you do. >> and so she d. they made a big happy thing of it. the whole family gathered in circle for a real country church wedding where susie introduced her parents and siblings to her new husband, a kid named marty. what was that like for you to? >> finding out she was pregnant and things were going to be a little bit different than you

>> the whole family accepted it becaese it w s susie's choice. >> before long, susie gave birth to a little girl named marya. followed by a son, shea. again, no real surprise. the marriage didn't last. >> she really loved her kids. they were really a big part of her life. when her and marty split, they re really everything in her life. so late 90s nowo susie was working as a medical transcriptionist in a place called glendive, and that's where she met ted casey. he w the real deal, a grown up this time, a rancher 14 years der than susie. >> he had horses and boy, that s just right for her. >> wedding number two. this was 1998. the kids shea and marya called ted dad. then there were two more kids,

for almost a decade, the marriage seemed to be just fine, but by then susie was sharing secrets with val about ted. >> he wanted to tame her, i think. i guess i kind of joke around and say that he wanted her to be home in time for the 10:00 news. he didn't want her to stay out and have fun. fun was just beginning at 10:00. >> at the casey ranch, love started to feel like one more chore. >> i think they grew apart. they just really both changed. >> then one liquid evening out at a bar things went seriously sideways. ted got mad, dumped a beer on susie's hefd, slapped her, and spent the night in jail. not long after ted pleaded guilty to fesdemeanor assault. susie was gone from the ranch. no >> she wasn't very happy with

some good decisions toafind mome happiness again. >> and so by the spring of 2008, susie and the kids were living at thedionderono apartments. a little up to like this, people niced what susie was upmato. liked her, but nsticed -- >> peopl thought of susie ag someone who was going through a time sowing some wild oats. she liked to have fun and she s having a lot of fun. >> then it got to that friday evening in april. >> when she came in to see me, she was really happy and she had makeup on, which wasn't really a n susie thing and that was great, so i knew something was up >> so val watched as susie bounded out the door while the two teenagers fended for themselves. and susie headed out on the

>> this girl has got to haae a date tonight. >> and the very next morning -- >> mom, pick up. >> when susie's worried children and increasing frantic family called in to check on her, >> call me when you get the message. susie, who always kept her phone within reach, did not answer. susie casey's sudden disappearance, casey's sudden disappearance. can the people she loved help solve it? >> i mean, what do you do? how do you find somebody? >> i was a detective. i was going to backtrack all of her steps. you could tell the house was dark and it was like an eerie feeling. eling. take in the sounds, from all sides, of an orchestra performing entirely for you. the jeep grand cherokee, with active noise cancellation to turn any street into a symphony. get 0% apr financing for well qualified buyers plus $500 bonus cash on 2015

the morning sun warmed toward another glorious spring day. glendive, montana.ebut in the ponderosa apartments it was anxiety that infected the air. 14-year-old myra tried again and again and again to reach her mother. >> call me when you get this. she knew very well that her mother enjoyed evenings out and trusted her children in the apartment. but she never once failed to come home. mariah's next call was to her grandparents. >> she told grandma mom wasn't around. so mariah's anxiety affected jack and marlene, too. >> sometimes you almost thought marya was the mom and susie the kid because marya was pretty

>> she was the somewhat more level r jded one. >> right. >> soon phones were ringing all over. susie satisfies sister carlene. >> i thought this is silly. she went somewhere, the kids forgot, and it's going to be a funny ha, ha. >> the kids were sufficiently independent to get themselves up and leave for their respective activities, but from susie not a word. across town, sister-in-law val hadn't heard yet that susie hasn't come home. we had a craft show in town and i thought she would want to come with me. when she didn't respond that morning, i thought that was kind of odd. when i was at the actual craft show is when i got the call from rusty. >> rusty, val's husband, susie's little brother. >> what did rusty say?

couldn't find susie when they woke up and that everybody was just reall'tworried be tuse this wasn't susie. she woulsenever just not tell her children or be there for em. and she wasn't there. >> val's next attempt to reach 'susie ensn't quite so calm. >> you need to call me back as soon as you get this message. your dad is freayesg out because we can't find you. i mean, what do you do? how do you find somebody? >> i was a detective. i was like -- i was going to backtrack all of her steps, and so that's exactly what i did. >> val made some calls. found susie had been drinking with friends the night before until about 11:00 p.m. for when she left for wat was apparently a date with a new boyfriend, someone susie had just started seeim? after her separation from her husband, ted.

>> i also thought she had maybe ajust fb ainted somewhere or had a heart atta m. an apsident, anything. >> still, when her mind settled, her first move was -- >> i thought had to go to ted's. >> because? maybe she was at ted's and they had an argument and she couldn't answer the phone. >> or maybe something happened over there. >> maybe something happened. exactly. >> ted casey pleaded guilty to assaulting susie six months before. that's why she moved off the ranch to the apartment, but when val arrived at ted's place. >> you could tell it was dark and ere was no cars there. it was like an eerie feeling. i just f t like i couldn't get out of the car by myself. >> so sh idecided to leave and picked up her husband rusty. the two of them got a key to susie's apartment. they opened the door and here's what they found. this was a videotape the police made later. >> as we kind of walked through the apartment and re

realized that she wasn't there, again that adrenaline burst something isn't right. something isn't right. >> it's empty. she's not there. she's gone. >> she's not here, yeah. >> so val decided to go find that new boyfriend susie had a date with. the last person to be seen with her. his name was brad holzer. >> he would know where she was. >> brad lived with his soon-to-be ex-wife less than five minutes from susie's apartment. val drove over and knocked on the door. >> i said susie's not home. we can't find her. she's not answering her calls and we're all really worried. then i remember exactly what he said to me. what do you mean she isn't home? i dropped her off at 5:00 a.m. that's when it hit we're going to the police. something's not right. >> it certainly wasn't. the man whe marriage was breaking up the last man to be with her didn't know a thing.

> coming up, susie's new boyfriend fields a few questions down at the station. >> did you ever wonder about bradsand whether he was capable of any bad thing? >> when she went missing, i wondered about everybody. everybody was a suspect. spect. sweetheart, don't look at me like that, it's gonna be amazing. this is a disaster! who's the genius who puts a girl in heels on a subway grate? miss monroe, eat a snickers. why? you get a little cranky when you're hungry. better? much better. this scene will never make the cut, morons. noalw you can create your own tour of italy at olive garden, starting at $12.99. choose 3 of 10 f vorites to eshoy on one plate. plus unlim ied salad and breadsticks. the best tour of italy is the one you create.

people disappear all the time in america. many of them turn up again. and maybe in some big city somewhere susie's absence wouldn't have raised the alarm quite so fast, but here -- olivia ringer was a young lawyer then.

this is glendive. she's got to be around somewhere. >> but when susie's brother and sister-in-law roared around town looking, it only made them more upset. >> as a kid, when you're younger, you always wish you had things you didn't have. i just always wished i had a big sister, and when i met susie, she was -- she was my big sister. and i guess i just never imagined she wouldn't be in my life. >> that afternoon, val and her husband rusty drove over to the glendive police department. they sat down th then captain now chief, ty ulrick. >> they said susie always answers her phone, always. i ment to my office twice and tried to call and the voice

in a town the size of glenn dive, the police were keenly are of her history. the abuse six months prior at the tonds erof soon-to-be ex-husband ted casey.re>> then val told the hief, susie's life had just become more complicated. >> the night before she disappeared said value, susie was with another man, a guy named brad, who she said she was crazy about, and who had to have been the l t person she had seen before she vanished. >> did you ever wonder about brad and whether he was capable of any bad things? >> when she went missing, i wondered a ut everybody. everybody was a suspect. ur mind continues to play and play and ptlay different scenarios of what could have happened and where she is. >> and well, that question mained unanswered. brad holzer came in for an

brad told the police that he and susie actually had quite a long history. >> how long have you known susie? >> well, we went out in high school. >> okay. >> she was 16. i was 19. probably went out for a couple of months is all. >> then they lost touch for nearly two decades until st. patrick's day 2008 just three weeks before she disappeared when their eyes met at a bar downtown. >> out of the blue, came up to me. i knew who she was right away. recognized her immediately. >> and in the weeks since, brad said he and susie spent every possible moment together, though given their 'ids and their spective tangled marital issues it was complicated. e night before she disappeared, said brad, susie had been drinking with a couple of girlf'iends before picked her up and they drove out of town to sit by the ylowstone river. >> then that's where we were go g on 10:45 until 11:00 until 5:00 a.m.

and did the same thing we usually did. talked, kissed, stuff like that. >> it was just about 5:00 in the morning, said brad, when he drove back to town and he parked across the street from susie's apartment. >> did you guys make out? >> probably for about five minutes. she got out, walked back to her -- across the street to her apartment. i know she was at least halfway across the street before i started backing out. she was that close to getting in that apartment. >> brad ore he drove straight home and went to bad. then brad cast suspicion elsewhere. >> brad, do you sow where susan's at? >> i have no idea. i wish i did. >> where do you think she is, if you had to guess? >> my guess would be ted. he had a hand in this somehow. >> there was one more thing, said brad.

the morning before he has last date with susie. maybe ted was behind it somehow. it reads, how's your girlfriend? how does your wife feel about it? tht.e sender a denise johnson. >> still in the dark as to who sent that and who the hell denise johnson is. >> that made the cop's ears perk up. a missing woman, e-mail. >> there's somebody out there. some jealousy probably. i needed to find out who sent those e-mails. >> so they told brad don't leave town, and they set out yo talk to susie's soon-to-be ex, ted casey. >> so much pressure. after a while, it explodes. >> the scorned husband in the interrogation room. and details of a confrontation with sus e. >> i wasn't happy. >> your thoughts about ted were not very friendly ones at that

by the sunday of that anxious weekend in april 2008, the whereabouts of susie casey was a local preoccupation in glendive, montana. >> there was a lot of talk about, oh, yeah, we saw her walking down the street sometime. maybe someone picked her up. >> the young attorney couldn't help but hear what people were saying. >> did she go home with someone? did she drive off somewhere? >> susie's mother was afraid something awful nad haelenede and for the second time she called sister car lean two hours away in north dakota.

something was really, really wrong, so we packed up suitcases and headed to glendive to see what we could do to help to find her. >> but where could they look? it is the size of delaware. far more hiding places than people. >> we had a few pings off of cell phone towers. we had horse back. we had four-wheelers, airplanes, helicopters, people on foot, and nothing. >> meanwhile, they processed susie's chevy trailblazer for any sort of evidence. same in her apartment. and found nothing. nothing of particular importance anyway. then they had a look around outside susie's apartment building and found something kind of curious. a couple of curious things actually.

alcove of the building next door to susie's place. over in the alley, maybe 40 or 50 feet away, looked like something had been dragged, something heavy along the ground near the dumpster. did either of those things have anything to do with susie's disappearance? maybe the rejected husband could tell them. ted casey. the morning susie vanished, he went to work, helped his brother with a project, then went to a rodeo. so by the next day, police were very eager to talk to ted. >> your thoughts about ted were not very friendly ones at that point. >> no. >> ted had reasons to be upset the woman was leaving him. he was angry, humiliated. a costly divorce was looming. child support to pay. first, they asked ted about that incident in the bar the night they arrested him and put him in jail. >> i poured a drink on her head. barely slapped her because she threw herself on the ground and we were both drinking.

but,kyou know, i suppose you get to such a -- so much pressure and after a while, it explodes. >> explodes? that was a curious thing to say. ted insisted he had last seen susie about 7:00 the evening before she disappeared when she dropped off the two little girls at his house for the night, but ted did admit that he confronted susie on the phone a couple hours later after receiving a strange phone call himself around 9:00 p.m. >> what was said? >> just that. brad holzer or whatever has been screwing your wife. click. >> brad holzer, susie's boyfriend of three weeks. >> what did you think about that? >> well, i wasn't very happy. i mean, i called her up and said, hey, who's this brad holzer or whatever? i said, i just got a call that

oh, no, no. i'd never do that. i've never cheated on you. i said we are still married even though we're not living together. and i just hung up the phone. well, she called me right back. then she admitted that she knew the guy. she knew who he was. and that was about the end of the conversation. >> was he upset? yes, of course, he said he was and yet ted told his interrogator he fell asleep right away. then got up around 5:00 a.m. to do chores and drop off his girls with a babysitter and meet a coworker at city hall by 6:00. >> i was thinking it was like 10 ten to 6:00 or something when i got there. >> ted drove past susie's apartment. he admitted as much on his way

put him around her front doot minutes from when she went across the street dishevelled. after making out all night with brad. the very time she vanished from the face of the earth. as the glendive police a departmert checked out the story, ted went home to look after the two youngest girls, o are ghving with him full-time, while marya and shea went to live with val and her husband. >> marya was just tormented. she didn't know ha to do with heifrself. she was so c se to her mom. ite. was just really, really hard for her. >> harder and harder for everyone as day after day the search for susie produced nothing. >> as time went on, was clear that she wasn't around anywhere, so it was just a really scary time. >> what were those days like? >> they were pure hell. you just sat and wait and wait

>> then nearly a month after susie's disappearance it did. >> the hardest day of my life. >> a horrifying discovery down by the river and another discovery down at the station. brad holzer's wife. what was she doing there? >> honestly, am i a suspect? even more lobster? you get hungry. and you count the seconds until red lobster's lobsterfest is back with the largest variety of lobster dishes of the year. like new dueling lobster tails with one tail stuffed with crab, and the other with langostino lobster mac-and-cheese, it's a party on a plate! d you know every btie of 'lobster lover's dream' lives up to its name.ehey, eating ow belup ang. so stop dreaming and start eating. there is a place where the sky is always blue. and the ki always eat their vegetables. because the salad there is

nearly a month after susie casey vanished on an early spring morning in glendive, montana, it was the yellowstone river that finally gave her back. >> i was sitting at my desk and the sheriff walked by and said there's a body floating in fallon. >> fallon is a small town 28 miles upstream from glenn dive. >> it was shore. took a look. i knew. at that point, we're changing from missing persons to homicide. >> susie's family gathered at val and rusty's house.

else, but it didn't go over well all the way because i had a job to do and my job was to keep this family together. the authorities came and told us it was her body. i didn't let my emotions just run with it because i knew we had those children downstairs. >> the older two, marya and shea, 14 and 12. carlene is the one who told them. >> i think that's the hardest day of my life. and i've had a lot of hard day, but that was the hardest i think. >> word spread that susie had finally been found. glendive mourned and relaxed in some degree. >> i think it was almost like a sense of relief. we found her.

>> by this time, agents from the montana department of criminal investigation had been called in to help the police. this is one of the agents. >> we determined from the autopsy that she was not breathing when she went into the water, so it was not a drowning. >> all right. so she was killed first. >> that's correct. the autopsy revealed that her hyoid bone was broken, which was consistent with strangulation. >> strangled? when and by whom? this time, brad, the last person known to have seen susie alive had been interviewed time and again. >> when she left, she was wearing my white sweatshirt. >> they talked repeatedly to brad's wife, though she and her husband maintained they had no motive to kill susie. they were headed for a divorce, but how did she feel really. after all, they were still living together. did brad's wife, who might be

a love triangle, have a reason to kill susie? >> honestly, we have a varietyu of suspects. yeah, right now both you and brad are. >> but brad's story didn't change. and susie were out all night. he dropped her at her apartment at 5:00 a.m. then drove a few blocks home and wept right to sleep. his wife insisted that was true. said she came home from a date of her own about 6:00 a.m. and found him already asleep. i went in, and the bedruom door was closed and i look in, and he was in bed sleeping. nt>> but brad's wife added to the mystery as well because it turned out she, too, claimed she got a strange phone call that week, the week susie disappeared. >> they said, can we leave a message for brad? i said okay. they said, tell him to stop messing around with married women. and i said, what are you talking about?

>> so it was a female? >> a woman? this was getting stranger by the minute. ted claimed it was a male who called him to rat on susie. brad said a female named denise johnson sent him an e-mail asking him how his wife felt out .is girlfriend. what policmareally needed was something concrete, something physical to prove brad's whereabouts to back upfris se re and clear his name. >> it was like we decided to check the bank for the footage and there it is. >> a u.s. bank branch just a couple of doors down from susie's apartm t. of course, it had a camera on its atm, so they asked to see the video and what do you know. very grainy and extremely hard to see clearly, it appeared to back up everything brad said. early in the morning just before

can see a pickup pull up across e stracyet from the ponderosa apartments. >> we see brad h loer pull up in his vehicle on the security cameras, and susie casey is with him in that vehicle for a period of time over 20 minutes. the dome light comes on. we believe that's when susie exits the vehicle. this was about 5:19 a.m. >> then brad's pickup pulled away out of frame. >> so when brad holzer's wife was interviewed, she had been out all night. she comes home and said when she got home at 6:00 a.m., brad was sleeping. we have a timeline from 5:29 a.m. and 6:00 a.m. where brad holzer has to commit this homicide and hide the body or hide the body and dispose of it later. we didn't feel brad had much of a strong opportunity or much of a motive to murder susan casey.

relief, as you might have imagined, to brad who has played the scene countless times. saying good night to susie and pu.lling ay before she got inside the apartment door. >> in hindsight, i bothers me that i didn't wait and watch her, but there's no reason that anybody should be there. it was 5:00 inerhe morning. the whole town was dead. i just remember needing to get home, wanting to get home as soon as possible. i didn't cross my mind that anything would happen or anyone was there. >> a gallant little gesture he didn't make. brad holzer has all kinds of time to think about that. >> sometimes i think about her, yeah. i wondered what we could have been doing right now. there could have been a future there. >> susie was laid to rest on a sunny day in may 2008 in a little cemetery outside her

lightest ah.re of how much more was still to come. >> seems like you didn't make it home last night. >> an angry messag from susie's husband ted and a closer look at his story. >> you know you were a person of interest. >> yes. >> what exactly did he do the morning of the murder. for adults with aneadvanchd lung cancer called "squamous non-small cell", previously treated wit platinum-based chemotherapy, it's not every day something this big comes along. a chance to live longer with... opdivo, nivolumab. opdivo is the first and only immunotherapy fda approved based on a clinical trial demonstrating longer life... ...for these patients. in fact, opdivo significantly increased the chance of living longer versus chemotherapy. opdivo is different. it works with your immune system. opdivo can cause your immune system to attack normal organs and tissues in your body

motives for murder. husbands scorned, convicted of misdemeanor domestic assault, on the hook for child support, and a life insurance payout. he was angry. of course, they had reason to suspect him. >> he drove by her apartment around the time she disappeared. that he was angry. tried to reach her on the phone. >> actually, i called susie. whatever time i called her, i left city hall then. >> yes, indeed. here is the angry voice mail ted left. >> well, susie, i just called marya. seems like you didn't make it home last night, so maybe what somebody called me and said maybe is true. you're doing somebody else. >> so once again, it seemed those age old motives pointed at the husband. >> 90% of the time you would be ght.

could be the excepedtion that proves t00 rule. ted was, in fact, at work that morn.ng as een by a coworker exactly when he said he was. >> if he did commit the homicide, wouldn't have enough time to dispose of the body. >> remember, they found susie's body in the yellowstone river 20 miles upstream from glendive. they pulled out the atm video by sie's apartment ilding.eted said he dropped his off about 5:45 a.m. ted drove to city hall to work. it's a small town and city hall is just blocks from susie's place. ted said he drove right past her apartment and sure enough. >> we could see a vehicle driving by at approximately the time ted said she drove by the ponderosa apartments. >> the time? 5:52 tam, just like ted told the

>> so he's basically got a 15-minute window where he's dropping his kids off and then he drives to city hall and works there for a period of time. >> given how close together everything was, wouldn't have taken much time to kill susie, hide her body, and retrieve it later for disposal. possible? quite, thought police. mind you phone records seemed to back up what ted said about calling susie the night she went missing. the angry message he left on her voice mail, the time stamp proved it was hours after she vanished. either ted was trying to fool police with the voice mail and his public movements that morning, or he didn't have any idea what happened to susie. and therefore this time the husband didn't do it, if he was telling the truth that is. >> you know you were a person of interest. >> yes, and you can expect that. >> sure, but how was it to be

>> it doesn't feel good. every place you go, everything you do you've got people watching, talking, pointing. but i did nothing wrong. i had nothing to hide from, so -- >> did the police believe that? you'd think if they did believe him, they'd make some sort of announcement that ted was in the clear, but they did not and so it was awkward, especially when they were looking for susie. >> did you take part in the search? >> i did. >> what was that like? >> it's kind of a tough situstion. you know, what happens if you find her if you're by yourself and you find her? >> that would suggest you knew where she was in the first place because you put her there. >> ted was still a target of the investigation and also quite suddenly a single parent of two

>> six days seemed like six months. you weren't sleeping much. i had headaches every day for over a month all day long. so how do you tell a little girl that her mother is never coming home, that she's dead? >> i guess i just told them. >> how'd they take it? >> they broke down. you know, they didn't let me out of their sight for quitert a few days. >> i can imagine. >> and especially when it came nightt e. they were glue to you. >> there was, remember, an insurance policy ovesusie's life. ted was the beneficiary. wasn't a lot, but they cut the check and ted casey cashed it. >> what did you do with it? >> paid her funeral expenses and what was left, i split four ways between the four kids. >> could have kept it.

>> was it enough to be very much help to the kids? >> not much. you know, there was probably maybe $3,000, $4,000 left after funeral expenses, but it helps. >> so does ted sound like a guilty man? but if it wasn't him and it wasn't the boyfriend, brad, then who killed susie? and why? >> please call me. i'm worried. >> a mystery caller. meone was desperat. to reach susie. >> really kind of obsessive. >> boy, this is something we need to look at here. r medicare part d prescriptions, wa reens says, carpe med diem. seize the day to get me out

there was something in the air that night. no doubt about it. not every deadly sin, but certainly several swirling on one city block in little glendive, montana. something that put at least two men, ted casey and brad holzer, on the same street within minutes of one another. who owned those eyes in the dark that watched susie casey in the moments before she disappeared? >> mom -- >> from the first moments, susie casey hadn't come home -- >> as you know, everybody's looking for you. give me a call. >> all of them tried calling the woman who never went anywhere without her phone.

just me. >> that phone was her lifeline, as susie's brother rusty and his wife val said in their interviews. >> i thought let's see which phone calls she had. >> that is when a very strange story began to emerge. that's where we had seen all those phone calls from a number we didn't kn whor)t belonged to. >> a number nobody recognized calling susie again and again all night long, but did that mystery caller leave a message? neither val nor rusty kn how to access susie's voice mail. but they did know who thst might. >> when i called and asked marya if she knew how to access her voice mail, she said yes almoste instantly. ty was sitting across the table from uld

>> if you don't call me back -- over and over again it was the same voice. >> i would love to hear from you and make sure everything is okay with you. >> it was starting to get more desperate and needy. >> i don't know what to do. u won't answer me. >> really reminding me of when you're a teenager and you have e your first crush and the guy or the girl goes to call them the next day and they don't answer. usually most of us would stop. >> pleaslet me know you're okay. >> but as a teenager, your em ions aren't really under control. they'll continue to call and caen and call. it was like that, but the messages just continued to get closer together and just more desperate. >> please let me know that you're okay. please. evorybody is v py worried about you. >> i thought that this guy's strange to call that many times and really kind of obsessive. >> and we're all worried.

>> yeah, who was he talking about? >> more to the point, who was this guy? who was he to susie, and why in less than four hours did he leave not one or two or four or six, but 22 voice mail messages for susie? >> please call me. i'm worried. >> and then val suddenly knew. susie had only hinted at it, but there was another man in her life. someone from her past with whom she had reconnected as her marriage to ted fell apart. this man, her long ago first husband, the father of her t g older children, marty larson. >> did she talk about him at all? >> i knew that she had had a previous marriage, but i didn't know anything more beyond that. >> marty had been out of susie's life for nearly a decade. no contact, no child support,

but then in 2007, marya, curious about her biological father, foun him on the internet and reached out. marty came to visit a time or two. at least once, susie took the kids to see him three hours across the prairie in billings, moopntana. her parents were astng the ery few people who knew. they were not happy. >> we got into an argument. i said susie, you don't want to do this. i said the family isn't going to really o for this, an she said, you mean everybody is going to disown me, so i just backed off. i said i'm not going to lose my daughter over him. and that was the end of it. >> how serious it got, nobody knew really. maybe they were just friendly. maybe it was more than that. now investigator ulrick typed marty larson in the database.

i'd seen ctiminal trss. >> remember, she married ted pretty quickly after she left marty in 1998. that wasn't the end of it. >> not long after the wedding, apparently marty drove three hours down the highway from billings to glendive and turned up outside the newlywed's house with a shotgun. it was never clear what he intended to do with it. he was convicted with criminal trespass and was slapped with what lifetime restraining order. no contact with susie or ted ever. >> at that oint in time, i had little red flag go up. boy, this is something we need to look at here. >> you could tell by the 22 phone messages. >> marty and his given first name was walter was very worried about susie. desperate even as those nighttime hours went by without a word from her. mart lives three hours away in billings, so was that where he was calling from?

out was check the cell phone towers. >> we looked at marty's cell phone and he was pinging from billings all the way to here. >> oh, susie, where are you? where are you? >> marty has a revelation for police. >> were you thinking that you two would get back together? >> that was the plan. an. te we're extending our 50% offer so you can save on most verizon, at&t or t-mobile rates. money! we s ed a lot money! the sprint network is faster. ta and, we're more reliable, with better coverage thtn ever. i like s int because of the reliability. my movies download mu ch faster. sprint's network is...

it's a long, lonely road

at the elevated speeds allowed on i-94, it's a good three hours east-northeast across the rolling prairie from billings to the ponderosa apartment building in downtown glendive. ping, ping, ping pass the ever listening cell phone towers. suddenly, the cop had homework to do. >> i had no idea who marty larson was. >> he was the third man to put himself near susie casey the night she vanished. that's why he called the state department of criminal investigation. soon after marty returned from the area, agent lee found himself standing outside the apartment staring at this freshly washed mini van. video again, courtesy of the police. >> it was very clean on the exterior because it had gone through an automated car wash. the interior of the vehicle had heavy condensation on the windshield. >> what did you find on the

the carpets had been cleaned. when you get into the cargo area, the back of the van was vigorously cleaned out with water and some type of cleaning solution. >> and in marty's apartment -- >> there was an empty bottle of toilet bowl cleaner in the kitchen garbage. detectives looked at the toilet in the residence. the toilets didn't look like they had been recently cleaned, yet we had an empty container of lysol bathroom cleaner. >> that wasn't all they found in the garbage. there was this. >> it appeared to be a list of expenses, as if someone was planning quite seriously for a las vegas wedding. >> a breakdown of the trip for lodging, paying for a minister to marry them, and the return trip home. >> when investigators asked marty to take off his shirt, they saw scratches on his back.

have gotten those? some struggle perhaps? while the search for susie is going on still, the agents suggested they all sit down for a little q&a and marty said sure, but -- >> can i ask you one question first? >> sure. >> am i under arrest for something or being charged with something? >> no. >> marty said he and susie had reconnected the year before mostly for the children, but right away, said marty, they fell for each other all over again like true soul mates. that time ten years prior when he took a shotgun to ted and susie's house all forgiven. he was a different man now. >> the ten years we were apart i spent thinking she hated me and she spent thinking i hated her. in fact, we still love each other very much. >> were you thinking you two would get back together? >> that was the plan. >> so said marty.

her on the phone. >> i told her before she went don't drink too much. you don't need to get a dui and get in trouble like that. >> she promised to call him back later. >> if i'm sleeping, don't worry about it. it's okay. wake me up. >> after all, said marty, they were a couple again. it was his business to worry about her. and when she didn't call -- >> then i called her at 12:30 because i hadn't heard from her. >> if you don't won't call me back by 1:00 -- >> i didn't know if she had gotten arrested or what was going on. and then i thought i'm going to go out there and see if she's okay, make sure that she got howe. >> what time did you leave billings, do you recall? >> about 1:30ish. >> sure enough. when police pulled video at the blue basket where marty said he gassed up, time stamps said 1:39

so he drove, he said, calling and leaving voice messages for susie during the entire 220-mile trip. >> i just need to hear from you. please, please call me. i'm worried. >> exp w-ecting to hear from susie saying i'm fine, don't worry. don't come. but susie's call never came. >> what time did you get into endive? >> 4:30, 5:00. >> again, true. s cell phoneinged off a tower. he said he parked armind the cornere.nd walked to her apartment. her car was parked outside as if she was home. >> i went in the building. i knocked on the door softly because her bedroom was near the door hoping it would wake her and not the kids. hoping she'd come and tell me she was okay. and there was no answer, so i went out and called and texted a few times, hoping to wake her up.

susie at all? >> no. >> okay. >> i wish i would have seen her. >> he swore he didn't see susie arri just before 5:00 a.m. with brad. dn't see what they were doing in her truck but he did leave town, he said. video from another nearby bank seemed to back him up at 5:45 a.m. leaving one last frantic voice mail. >> just hoping to hear you're ay. >> police are paid to be skeptical. >> there's no doubt in my miid you aaw her this morning. >> no, i didn't. >> but marty stuck to his story. and hen detectives asked him amwhy his mini van was so freshly washed -- >> on the way up there, i did kind of have one sort of major thing. there was a deer in the road that i hit and there was a bunch

>> okay. so i wentyaud cleaned the bugs off of that. hoping the drive through car wash would spray the deer ofd. i didn't do a very good job though. >> a deer? really? but -- >> did you check into whether or >> we di we checked with the highway patrol. it was c.nsistent with a deer. it was not a live deer he hit running. >> when they tested the tissue on the van, sure enough it was w not huyon. it was animal tissue. but then when police asked if there was anyway they'd find susie's dna in, on, or under the van, marty said something as he often did that made police wonder. >> well, i guess what i'm saying is -- what i know is -- my thought is that was a deer. i guess i don't know for certain that it couldn't have been her. >> would he try to tell police

>> is heere something you want to tell us? >> no, i haven't done anything. you can scrape everything out from underneath that van. it's deer as far as i know. >> and if that wasn't weird enough, as the detectives left >> oh, susie, where are you? where are you? those kids need you. i need you. i love you, susie. just wish i knew where you were. >> marty was now the prime suspect, the man in the crosshairs. but suspicion is so easy. the real question was did he do it. what cop or prosecutor would

on a wild bet like that? >> susie's death consumed him. he was going to get justice for our family, even if he had t do it himself. >> a whole new tragedy is about to hit susie's family. ily. i accept i'm not 22. i accept i do a shorter set these days. p i even accept i have a higher risk of stroke due to af , a type of irregular heartbeat, tnot caused by a heart valve problem. but i won't play anything less than my best. so if there's something better than warfarin, i'm going for it. eliquis. reliquis reduced the risk of stroke better than warfarin, plus it had significantly less major bleeding than warfarin... eliquis had both... that's what i wanted to hear. don't stop taking eliquis unless your doctor tells you to, p as stopping increases your risk of having a stroke. neliquis can ca e serious and in rare cases fatal bleeding. don't take eliquis if you have p an artificial heart valve or

once susie's family found out that her ex-husband marty larson had been in glendive the night she disappeared, reaction was quick and to the point. >> if i knew all this ten years earlier, i would have taken him for a ride. >> here's what most thought right away. >> it didn't add up that it was brad and it didn't add up that it was ted. >> but marty, perhaps? there were signs like those obsessive voice mails and the bank video and his own admission that he opened to reunite with

the probability he saw susie canoodling with brad. the minivan washed on his return home, and yet marty larson was not arrested. >> i think that frustration was really, really hard for the family. >> what was your expectation? that they would look at this material they had and just go and arrest marty? >> i guess i anticipated these things would move forward and who was responsible would it held accountable and time just kept on going. >> the thing is at tham point susie's sister-in-law val and rusty were still hearing marty and ted were both suspects. at the time, susie's two yupg he's kids with ted and the older two living with val and rusty. >> it was extremely difficult

bedroom, his own space, but at night he 'scouldn't sleep in his room. he had to sleep with marya. >> because?i>> he was scared marty was going to come and take him. >> his own father? >> i don't think he ever really called him father. i don't think any of us really did. i think he was just afraid of marty. >> val had a newborn of her own to go along with those extra responsibilities, and an overwhelming sadness that seeped into her bed, her kitchen, her life. an unwelcome house guest that simply refused to leave.to>> my son was 4 months old woun sie was taken from us.r i don't remember him walking. i don't remember those moments i should remember as a mother. >> meanwhile, the investigation was stuck in the weeds. >> i was thinking couple months and we're going to have an

the pieces at that time that we needed. >> 2008 went the way of all years. ted kept to himself. marty moved, left billings, went to phoenix, got a job. and at home in glendive, susae's brother, val's husband rusty, was having trouble with the rage. >> susie'sodeath consumed him. when he went to sleep at night, he told me one night that he just wanted to stop feeling. i think it just haunted him that he felt he could have done something. >> and by the time a representative at the attorney general's office met with the family, many felt they were teetering on the edge of sandy.

what was the hold up? >> that day i asked if she could tell us, as a family, that ted was no longer a suspect because the two little girls were living with ted at the time a marya and shea were living with me. just felt like i was the only pers.n trying to salvage the relationship with the little girls and their siblings. and i just really wanted her to kind of crush that wall down and say that he wasn't a suspect and her response to me wasrthat c e case is still moving forward and he's still a suspect. >> that's quite a thing to hear. >> yeah. i just felt like i really needed to hear that at that tome and i didn't get to hear that and that it was still possibly he could have had ikiolvemest. >> ted, who still under a cloud of suspicion, believed that marty killed susie. >> there was a lot of nights i didn't sleep real good wondering if somebody was going to show up

a gun. >> but it was rusty who delised a plan to do what prosecutors and police officers seemed unwilling to do. >> he was going to get justice for our family, even if he had to do it himself. >> what did you mean by that? >> he had made several plans about how he was going to kill .marty, take marty's life just like mo ty took susie's. >> what would you say to him when he said things like that? >> that the case was moving forward and jhat wasn't something that he needed to do, that we had a son and his son needed him and me and that he couldn't leave us. >> eventually, it all came to that anywakiy. first, val and rusty divorced. then in november 2011, three and a half years after the night

>> i got a phone call in the middle of the nighu.ntit was impossible to believe that. >> rusty, her brother, 32 years old committed suicide. >> we've already lost susie. this can't be happening too. so it was really hard for my brain to wrap around that. >> so jack and marlene went to the little cemetery in cyrcle to lay another child to rest. >> it crushed them and then to lose their two youngest. it just seemed like theylaged 15 years. >> do you think rusty would be around today if they moved quicker on that case? >> i try not to go the.e. i mean, there's all this what-ifs. >> it wasn't long after her rusty eas puf in tge ground a new county attorney was elected in glendiv a you've already met her. >> i felt we had a duty to give

marlene and their family as to what was going on. if'she case was going to go somewhere or it wasn't, they needed to know. they couldn't be left dangling out there. >> and they certainly were dangling. for an answer and justice might haveooimply ended there. but one morning as olivia was settling into her new office, there was a knock at the door. a man had come to call and he smiled and said -- >> hi, i'm brant light and we're going to try a homicide. >> my stomach was in my throat. >> an arrest at last and new anguish that no one in the family saw coming. >> it hit you pretty hard, didn't it? >> yes. re of business and take care of the people who matter most. so when your tax refund arrives, make it go a little further at walmart.

olivia could scarcely believe her eyes. the man at the door, the man who clearly intended to enlist her in some sort of cause, was one

all of montana. >> when you saw him in the door that day, what happened to you? >> i think my stomach was in my throat especially when he said we're going to try a homicide. are you kidding me? because i am new here. he brought boxes of files and he said i'm going to be back in six weeks, and i want you to get on this and read all this stuff and we're going to talk about how we're going to do this. >> this is brant light, who before he owed up at olivia's door, was appointed the state attorney general's chief prosecutor. they often help small jurisdictions handle big cases. ti>> how dad younget involved in this particular case? >> well, i had come to the attorney general's office. there was another chief prosecutor at that time simply didn't think there was enough evidence. i took her position and i told my team, let's look really hard at this. months later after a really hard look, i thought it was a great

i thought circumstantially it was overwhelming. then brant light met with susie's family after their patience and pro sed he would issue an arrest warrant for marty larson. >> i saw my family and their family, a good strong family, and to have this death occur, to her get out of a car and never make it to the front door 20 steps and we can't explain to them what happened in those 20 steps, i thought they deserved to find out. >> in february 2012, four years after susie's murder, a phoenix s.w.a.t. team descended on marty's apartment on his way to work. back in glen dive, a certain ex-suspect ninely relaxed. >> when you knew he was under arrest and in jail, how did it change your life? >> it took a lot of stress off me. >> mr. larson, i'm the assistant chief with the glendive police

how are you doing? >> and the man who originally took susie's missing person's report sat down to interview marty. >> when i walk in, i expect someone to say you're crazy, i didn't do this, i don't want to talk to you at all. >> but -- >> i found a guy sitting in a chair with his legs crossed and arms across the side. >> i have no idea what happened to her. i don't know how she passed away. that's it. i pretty much coknew when i was targeted years ago that something like this could happen at any time. i knew this day would come. >> what did that say to you? >> >> he's been thinking in the back o his head that he would be arrested for this crime. >> they took marty back to montana, stuck him in the county jail to await his murder trial, and when the spring of 2012 arrived, it seemed things were

family. >> it was a lot of relief. especially mom and dad. they felt susie woald finally get some justice. >> there was another reason finally for the family to celebrate. susie's eldest child was graduating from circle high school. senior photos were taken, announcements were printed up and sent out, a party was planned in circle. then the day before the ceremony -- >> she said it's going to be my graduation and my mom is not here to see it. i said i know, but she'll be with you and she cried. marya and marlene dried their tears and the young girl bounded out of the house and drove away. >> what happened? >> they said she fell asleep. >> went off the road.

nothing. she hit the ditch and it rolled. that kid would never leave without her seat belt . that night she didn't have it on and it threw her out. >> marya larson was just 18 years old. >> all i remember is answering the phone and my mom telling me and that's all i remember. i just dropped the phone and just cried. cried and cried and cried. i just couldn't believe that that could happen three times in one family. >> i never really grieved for susie, just like i never really grieved for rusty until mariah's accident. and that was the day i grieved for all three of them. >> i can't imagine that scope of

i don't know how you managed it. >> i don't know either. >> that hit you pretty hard when she was killed. >> yeah. >> is that the point that gets you every time? >>ta yeah. >> marya was laid to rest in that little cemetery outside circle next to her uncle rusty and her mom susie. >> she had a hard time livin without her mom, and i guess that's why she finally went to be with them. just about didn't make it through that one. three of them. >> and right along with the family that dad was the new prosecutor on the case. >> it showed me a lo about brant light because he traveled from helena after meeting shat 'girl only one a me to her

>> and he had a message for the family and for marty ltrson. >> it was very clear in this case from both sides there was not ing to be any plea negotiations. we never talked negotiations. weug simply talked about trial. let's go to trial. >> bravado? circumstantial cases, specially like this one, can be tricky things. coming up, the shoe print, those drag marks, and that surveillance video from the bank. would any of it point to marty? >> it looked like a different person. all of us were a little taken aback. aback. nd a half days when used at the first sign. without it the virus spreads from cell to cell. ly abreva penetrates deep and starts to work immediately to block the virus and protect healthy cells. you could heal your cold sore, fast, as fast as two and a half days when used at the first sign. learn how abreva starts to work immediately at abreva.com don't tough it out,

glendive, as we have said, not a very big place. the walk from susie's apartment door to the dawson county courthouse would take less than a minute. five years from crime to trial. five years and one city block where in april 2013 marty larson finally faced a jury. >> clearly, to me, he was the person that committed that crime. now my chore was to go out and prove it. >> but when marty walked in, the courtroom gasped. >> he didn't look like the picture that i was shown of him. >> he had lost 77 pounds like

all of us were a little taken aback. >> was it intentional? more on that in a minute. first, prosecutor light listed what he said were motives for marty to kill susie. motives as old as time. jealousy, pride, rage. >> i think marty was absolutely convinced that he and susan were going to get back together. i really think he thought that was going to happen and then all a shdlen he comes brad. prosecutor, d phone records backed it up marty made those phone calls to his estranged wife wnd ted casey before the murder. alerting these people that something untoward was going on. >> i think at that point he thought, well, let me just break this up. his efforts were all just ab t breaking them up. >> that effort included e-mails, though marty denied it.

>> no, i did not. >> a search of marty's computer pirevealed that he created that e-mail account under the name denise johnson and sent those e-mails to brad asking about how his wife felt about that girlfriend. when police showed up at marty's door for the very first time -- >> he's erasing things on his computer and defragments the hard drive. >> appeared to be getting rid of something. >> right. >> on the night susie disappeared, phone records revealed that she and marty last spoke at 9:51 p.m. by then, susie was aware that marty had been trying to sabonage her relationship with brad. after the phone call, susie called her daughter marya with a question. >> she wanted whto know how to restrict a number. >> i asked her why andhe told me because marty was calling and i -- he was calling ted.

susie stopped returning marty's call. that's why at 1:39 a.m. marty was caught on that gas station camera leaving billings to go to glendive. >> i think it was his intent to confront her, to find her and confront her about what's going on. >> the jury heard marty left 22 voice mails as he drove over the next three hours. his cell phone pinging ig glen dive just before 4:30 a.m. then by his own admission, marty parked right around the corner from susie's apartment building next to the bank. anll. that's when the bank's atm started telling a story like nothing else could. 4:27 a.m., prosecutors argued this figure right here is marty walking towards susie's apartment. >> our theory was he got to susan's apartment before brad, before she returned, and there's a little concave, a little store

we believe that's where he was standing. >> that's when he left that footprint found in the dust found in the alcove next to susie's. then the tape showed at 4:52 a.m., brad and susie pulled up in ad's truck. 5:19 a.m., the dome light came on. susie opened the door and got out just steps from onr apartment. >> when she stepped out of brad's car, after he had stewed in that concave for 15 to 20 minutes as they were in the car doing what'v r the hwere doing, i think he was extremely angry. i think he confronted her. i think she confronted him right back. >> i think she told him when she was going to continue a relationship with brad and that marty and her were done, he was a no one is going to have susie sort of guy. >> i think that's when he strangled her. >> strangled her, pr

argued, but not before susie left those telltale scratch marks on marty's back. he dragged her body across the alley reaving those drag marks near the dumpster. at 5:38 a.m. a figure walked back towards marty's mini van. after he walks back, the next thing you see is that silver van pull in front of susan's. there's about a five-minute wait. i believe he's putting the body into the back of that van. then you see the van pull aside. >> that, said prosecutors, is when marty started driving back to billings. >> you have a body in your van. i think the river was the fastest and easiest way for him -- and to buy him some time. >> prosecutors produced this video showing marty 78 miles down the road stopping for gas, at 8:15 a.m., wearing a white t-shirt and black shoes that were never

did he throw them away whehihe du mped her body? at 10:29 a.m., marty was back in billings leaving his first voice mail in almost five hours. this one with a decidedly different tone. >> good morning, sweetie. i was just hoping that you would be willing to talk to me. i have my other phone charging right now. if you could, give me a call on this one. thank you. >> totally different tenor. i thought he would have been more angry when she still hasn't returned your calls. they don't know where you are. no he's in alibi mode. >> the final piece of the puzzle for prosecutors? remember how marty vigorously cleaned his mini van inside and out. not quite enough. e hair was foundk it was in the back of the van where he had put the body. >> we did a mitochondrial dna and it was hers.

believed he laid her. >> a strong circumstantial case, except the marty who showed up in court did not look a bit like the man in the videos. >> my belief was he tried to change his look so he would not look like the person who was on t the bank atm. there's a big husky guy, maybe 210-pound man, and here's a person who might be 150 pounds, 160 pounds. >> but would it work? good question. after all, the state's case was entirely circumstantial. there were no eyewitnesses. the bank video was so bad even the judge wondered at times what he was looking at. they never found shoes to match the footprints in the alcove. brant light had taken a chance all right, on a difficult case.

>> ted casey was the one, i believe, who had a real motive. >> was the wrong man on trial? >> i couldn't have done that. >> can you see how it looks in >> marty larson speaks. >> i can. >> and so does the jury. ury. here's something to shout from the mountaintop. pcricket's plans start at $35 a month, pafter $5 auto pay credit. p with more 4g lte coverage nationwide pthan tmobile or sprint. pcricket wireless. psomething to

marty larson's defense attotorney hadlone big headline for the jury. >> i don't think anyone knows how this crime happened. >> she is a seasoned and respected montana defense attorney and her review of the prosecution was harsh.

made for a good story, but offered very little in the way of actual proof that marty killed susie. >> i believe there was not enough evidence to bring this case and that's one of the reaskns why it wasn't filed for all t. te years bed.use other prosecutors had determined there wasn't sufficient evidence. >> much more evidence against ted casey, she said. >> ted casey, i believe, is the only one who had a real motive. they were fighting about the children, the monetary aspects of their marriag and she had indicated to marty on several occasions that she was fearful of ted. and i believe his recounting of what he rd that morning, had it been proper ly in estigated, would have been less than a perfect alibi.

was no evidence that ted or, for that matter brad or his then wife or anyone but marty larson killed susie. the defenb dant himself testified at the trial and agreed to sit down with us too. >> so what do you want people to know about you? >> i guess the main thing is just i had nothing to do with killing susie. i would have never done anything to her or to take her awaymarom my kids or her two little girls. i couldn't have done that. >> marty insisted that his very last contact with susie was that phone call at 9:51 p.m., eight hours before she disappeared. >> what happened in that nversation? why did she not want to talk to you at all afterwards and block your number? >> during that call, she called to ask me -- i don't remember if she asked me or if she accused me of calling ted. >> in fact, you had. >> i did.

i told her i didn't do it and it wasn't me. >> why would you do that? why would you lie ab t it? >> lying about it was i knew i had done something stupid and i felt guilty about it. why i did it, a lot of it was because of being hurt, because what she had bee,elling me was that whatever she had, as far as a relationship with brad, she had been telling me for a week to ten days or so that that was over. >> apparently it wasn't. >> no. and i guess somewh.andin my head suspected that and that's why i sent the e-mails. there was a lot of confusion. >> confusion or something else that made him decide to drive three hours to susie's place in the middle of the night. >> that's a bad decision, right? you see that now.

the whole time i was driving i was hoping that she would respond and say i'm fine, so i could just turn around and go home. that was all i wanted was to know she was okay. >> and still maran ins sted that when he got to her apartment he just didn't see susie right across the street with that gue brad. in a spot where he couldn't have seen her walking to the door. >> that's the part that sticks with me. here's a guy who cares deeply about this woman and what she's up to and he sits e ere he can't see the entrance to her apartment building? don't give me that. that's crazy. >> i can't make people believe anything. i knowtwhat i did. i know where i was. >> listen, you put yourself there. that's the point. you put yourself at the crime scene. >> i put myself in a position for them to look at me. >> right. you had the opportunity. you had the motive.

>> you could have in other words. >> within that time frame, yes. >> can you see how it looks? >> oh, yeah. i can. i can. there are a lot of things i don't understand myself. i don't understand why, especially now, i couldn't have stayed home and tried to contact her. i thought i could do something to help if she needed help. >> sometimes with a girl like susie the thing you can do to help is to walk away. >> yeah, i think it probably would have been best, at least for me. >> the jury was out about as long as it was for marty larson drove from billings to glendive. the night poor susie left his life. three hours. the verdict, guilty. >> what was it like to hear that guilty verdict?

and hugged. it was just like a big weight just lifted off of you. >> there's something hugely important about justice. couldn't bring her back, of course, but did the verdict matter? oh, yes. >> it really did set my mind at ease. it really did help us to move on. >> the first thing i do is to turn to the family. i love to look in their eyes and see the smiles on their faces and the joy they have. for me, that's what it's all about. >> i'll never have another time that i loved being a prosecutor than i did right then. >> this is where marty larson lives right now. crossroads correctional, in shelby montana, near the canadian border. >> what did they sentence you to? >> 110 years. >> your first parole possibility is what? >> 2042.

>> yes, it is. >> but of course it's far more than just a long wait for susie, rusty, marya. the cascade of grief begun that night was deep and long. >> i can't understand how the guilt and the emotions aren't just consuming him because losing her is still consuming us. >> he took her life and he took part of our hearts, but he'll never break this family up and he hasn't. >> no, he hasn't. shay, just 12 when his mom was murdered, graduated from high school in 2013. ted and susie's daughters, kyana and charlee, were junior bridesmaids when their aunt val remarried.
