. she felt that she was being watched. all the wounds to her body. it was an angry attack. >> a nursing student with three children, nobody was busier than angela. as soon as class was over, she was gone. >> back home? >> i'm. >> that's what they found her. >> the officers could see a lot

of blood. >> police thought that her boyfriend's behavior seemed odd. >> he doesn't going. >> people thought that there was something suspicious about that. >> but he had an alibi. >> did he tried to point the finger anybody else. >> he did, angela's ex-husband. >> the ex had an alibi to. >> he came off as very calm and collected. >> there is something else missing. >> we get a phone -- call >> until somebody found it. >> they asked if i would be willing to come up there and wear a wire. >> just one old friend talking to another about a secret that she was dying to share. >> i think that she was almost proud of the whole thing. >> a case where the biggest twist came after the verdict. >> wow, >> that was my response, wow. this is a different analysis perry confidential because they really missed parts. >> hello and welcome to dateline. working mom angela walker dream

to becoming a nurse. she's working on both ends to make it come true. then, angela was murdered. investigators suspected that the attack was personal. just when they thought it was case close, turns out it was not. they set an elaborate trap hoping to catch a killer. here's keith morrison with prairie confidential. >> it was dark on the great central plains. luminous. in the early hours of that friday the 13th of november. the small light winds shivered on flat, deserted streets. and nipped the freezing little teeth at the ruins of autumn, in north dakota. was there muffled cry? the sound of a car making haste away. no one heard. not a thing. it is a modest place, minot. modest in a good way. and on commonly friendly, comparatively speaking of course. >> it is comfortable. it is a family community.

>> north dakota nice. maybe an old-fashioned phrase but it still fits. >> the people who have been around a long time, still greet each other on the street. >> as they did that chilly morning in november, 2015. when parents dropped off their kids at this elementary school. and where later, at my knots state universities school of nursing. professor diane shoal wondered why one of her students had not shown up for an 11 am exam. >> before we all started taking the test, i said, has anyone heard from angela? >> angela was this woman. >> my name is angela wilder. i'm a student nurse at am s u. i will be assessing your cardiovascular system today. >> she was just this sweet little southern girl. >> sweet little southern girl? >> yes. it was miss diane. and yes ma'am. and no ma'am. >> okay, i will let the doctor know and he will be in with you shortly. >> angela wilder, was in addition to a nursing student, a mother of three. who, just days before, had revealed to her professor that she was pregnant.

>> did you have any advice for her? >> well, we talked about how stressful school is. we talked about her not feeling well. and that is when i told her, yes she is expected to come to class. if she could not, she could call and let me know and we would make other arrangements. >> but that morning? no call. no angela. what's she ill? class was over, before one of dianne students dropped a bombshell. >>, she said, i think it was angela's house when i drove to school and there is police tape around it. a lot of people in hazmat suits. >> and indeed, it was angela's house. this little place, next to a lutheran church. across the street from that little elementary school. it was angela's fiancée, home from a night shift who called 911. >> i just got home. my back door is kicked in, and

my girl is not answering the phone. my son is inside with her and everything. i am about to go in and see what is going on. >> okay, why don't you just wait for the officers? i will get them over there. >> so, the fiancée stayed outside. the officers went in. the house was neat, tidy. they found the two year old, unharmed. they went down the hall, looked in the next bedroom. and there she was, very dead. >> i did not know at the time exactly, how many times she was stabbed. but i knew that it was vicious. >> my police, detective sergeant, dave goodman. >> how many eventually did you find out? how many stab ones? >> somewhere near 40. >> and there was this fiancée. and you have a crime that looks like a crime of passion. what story did he tell about coming home? >> he reported that he had been at work all night. when he arrived home, and found the back door to the residents kicked open. he said, he was obviously concerned about that. >> if that was me, i think i would have rushed in there to see what was going on.

with my family. >> and i say that to. of course, until you experience that on your own, i guess we do not know how any of us would react. >> still, good men's detective instinct kicked in. >> so what's if the dispatcher told him to wait? would a innocent, worried, parents do that? it was suspicious. why did angela's fiancée, chris, stay outside? and, had he really been at work all night as he said he was? they took him downtown for the first of several interviews. where goodman and his partner, detective, sergeant, chris systematize sized him up. his name was kris jackson. how did he present? >> he was calm, he was crying. he was upset, he was mad. >> where was he that night? chris said, angela drove him to work at walmart. dropped him off before 11 pm. >> and that kids are, and i say, i love you sweetheart, drive safe. have a good night.

>> angela was nervous, he said. afraid to be left alone. >> why did he say she was anxious that night? >> the night before, she said, that she heard somebody messing around at the front door of the residents. she felt like she was being watched. >> so, said chris, he called and texted her repeatedly. but after 2 am, he said, she did not pick up when he called. >> and he figured that she had fallen asleep. >> but no, she was not sleeping. but who killed her? and why? when chris first arrived at the police station, they let him make a phone call. it was obvious, he had his own suspect in mind. >> richie is probably be piece of -- who did it. god, i hope they piece it to him. i hope so. >> richie? who was he. a pregnant young mom dead, her toddler nearby and an

investigation about the lead to even darker discoveries. coming up, her fingernails are broken off -- >> detectives talk to richie. >> what happened to your face? >> you have a scratch on your face. >> are they getting closer are getting played? >> did he have an alibi. >> he said he did. >> when dateline continues. when dateline continues i just love that word "bundle." it's so fun. two things coming together like a force of nature, like it was really meant to be, y'know? yes, yes, i do. and i'm so glad you wanna save money. rodney, set up a bundle for jon hamm. mm! of course! jon, is it still cool if i catch a ride home with you? i never said it was. but technically you didn't say it wasn't. it's not. yet. did i tell you i bought our car from carvana? it's not. yeah, ma. it was so easy! i found the perfect car, under budget too! and i get seven days to love it or my money back... i love it! i thought online meant no one to help me,

fickle they. like people sometimes are. is that why angela wilder's fiancée chris was so angry? >> richie is probably the piece of -- who did it. >> there was a history to this. >> long before that november morning in 2015. far away from north dakota. in alabama, angela met richie. at church. they were the best of friends as kids. and after angela had a baby as a teenager, it was richie who scooped her up, married her, adopted her little girl, and before long they had a boy of their own. all witnessed by angela's sister, krystal. >> she tended today guys who were funny. that were gentle. that were intelligent. and really, richie was all those things. richie was in the air force, that's why they moved to minot. there was an airbase there. and it is where angela pursued her dream of becoming a nurse. >> she took classes whenever

she could. she could have up to two jobs at a time, still attend her classes, and take care of her kids. >> why did richie and angela's lifetime bond rupture? who really knows? but there is curdled into a corrosive, toxic, anger. richie was court marshaled, convicted of domestic abuse. drummed out of the military. the divorce followed. but then, like the prairie went, their affections shifted. richie remarried, a small town north dakota girl named cindy. who had moved to minot and become a kindergarten teacher. and soon cindy and richie had a baby of their own. and angela got engaged to chris, and she had another baby too. and these two new families, all settle down again. or they might have, except for richie and angela's toxic custody battle. >> she said he is just fighting me all the time. you know, it has been really hard with the kids. >> it was bad between those

two. scary. >> i got a frantic phone call from her one morning, and i was like, calm down, what's going on? she says, it's richie. i just woke up, came out of my bedroom, went into my living room, and he is sitting on my couch. and he looked at me and said, see? i told you i could get to you if i wanted to. >> is that what happened here? an angry, ex-husbands revenge? >> hello, hi, are you richie? >> yes ma'am. >> hi richie, my name is -- >> a few hours after the murder, after talking to angela's fiancée chris, detectives good men and nutcase, call richie in four a top. but he did not seem to know what was going on. >> and i will tell you, angela 's dead. >> oh really? >> yeah. >> did he seem upset by what had happened? >> he did not, no. >> that strike you as odd? >> it did, yes. >> will you would want to have some reaction. it is the mother of his child. >> that is what we would expect. >> their questions got tougher. >> did you kill her?

>> no. >> no? >> now. i am 100 percent truthful. >> did he have an alibi? >> he said he did. >> did you work last? night >> from 7 to 11. yes ma'am. >> okay. where did you go after you left work? >> straight home. >> can anybody tell us what time you got home? >> yes, cindy. >> that is his new wife, the kindergarten teacher. who confirmed that when she woke up with the baby for the night, richie was beside her in bed. >> he was home, the three times that i was up. >> if that's the truth cindy, then that is fine. maybe he was home during those three times when you are up in the night. is that possible? sure, but what do you know about this? >> i do not know anything. >> so maybe the detectives could get something from the crime scene techs. who told them that angela had tried to fight off her killer. >> her fingernails were broken off. it appeared the assault had occurred while she was in bed and ended up on the floor next to the bed. >> your dna is not going to

show up anywhere on her? >> no. it is not possible. i was not even there. >> going to show up under her fingernails? >> now. >> but they could not help but see, the scratch. >> what's happened to your face? >> where? right here? >> you got a scratch on your face. >> he had the story that he had been wrestling with his younger son and that's how he had gotten scratched. >> police also impounded two cars driven by richie and his wife. and in one? a small spot of something. dark brown, on the inside of a door. >> visible to the naked eye. but not obvious it was blood. but enough suspicion for them to go ahead and collect that. >> and when the lab called back a few weeks later with news? well, it was quite a moment. >> we were excited. we could not believe it. >> that spot in richie's vehicle? it was indeed, blood. angela's blood. >> we ended up standing up

during that conference call and hugging, we were so excited to get that news. >> but no arrests, not yet. not until more results came in on material found under angela 's fingernails. >> about a week later, we heard back on the fingernail clippings. that came back to richie, we said okay, let's go get him. >> and so they did. >> we found him at a local gym in town. i said i have an arrest warrant for you in the murder of angela. >> richie wilder junior was charged with murder. he soon pleaded not guilty. >> we offered an interview to him. he did not want to talk, and he went to jail. and then, >> a couple of months later. >> richie do you remember us? detective mai tai's detective goodman. >> richie asked to see the detectives again. because he was finally ready to tell the truth. and blow the whistle on his accomplice. wait, accomplice?

a new and shocking story that put him and his ex wife angela in the bedroom, the night that she was stabbed to death, but did he kill her? oh no, which he said. so who did? richie was finally ready to reveal the secret, to point the seeker at the very man that first accused him, the killer was angela's fiancée, chris. >> i don't know what the -- you doing, man. >> let's toughen beginning. corset that he discovered angela cheating when he was working at walmart. he wanted to catch her in the act, prove that she is an unfit mother, so that they, chris and richie, goodwin custody of their respective kids. it's not a good to richie, so, friday november the 13th, 2:30 am. >> richie said that they pick

tear up from walmart, they drove to the house, and they were supposed to catcher in the act of cheating on chris. >> when we opened the door, it looked like they had to people in the bed. the first thing i notice, there was a body pillow. >> maybe chris did not understand that because he went crazy and started stabbing her. >> i went over to her, i touched her neck to feel her pulse because she was kind of -- i want to touch her pulse, she leaned up and scratched the mess out of my face. i grabbed her hands and was like, i love you. >> that was why his face was scratched, said richie. and his dna was under her fingernails. anyway, he drove chris back to work at walmart. >> or decrease ride? >> in the passenger seat. >> the same side of this car where that spot of blood was found, angela's blood. >> when we first interview

discs, richie, why did you not tell us? >> one is, if utah no, and i will kill your wife, i will kill your little one. >> it was quite a story, the only problem, walmart, where chris worked, had cameras everywhere. it just so happened that detective goodman spent most of the night with detective richie watching the videos. videos that kept witnessed of every movement every minute. if christophe to store to kill his wife than good men would not find him on any video shop between 2:50 am and 3 am. >> every 5 to 10 minutes, we have him there at the store. we have him in the entryway sitting down eating his lunch during the time that he told us he stabbing angela. >> in fact, the only times chris briefly left the store, where his scheduled breaks. so he couldn't simply have taken part in such a game with

ritchie? >> he could not have. and we knew that. >> good men held back as richie spun his tail. and then? >> chris did not leave walmart during those times. >> i know he did, i picked him up. >> i know he did not, because i watched him on video. >> and minutes later, richie wilder, his bluff called simply folded. >> you can stop anytime you want. >> i will stop. okay. >> and so, when richie wilder's murder trial started a few months later, prosecutor kelly dillon was confident. >> i felt i had a very strong case. my strategy was to present the crime scene, presents the evidence and present richie's multiple stories about how this went down. >> straightforward enough. as richie listened, his wife cindy dutifully sitting near the defense table, the defense called people who told the jury about angela's blood in richie

's car. about dna linked to richie under angela's fingernails. about the changing, self serving, stories that ritchie told. >> she like leaned up, and scratch the mess out of my face. i grabbed her hands, and she was just like i love you. >> up to that point, i was thinking that he might be able to convince a jury. but then when he got to the point when he said that angela sat up and said, richie! i love you. it was done. it was done for me. it is just such an incredible thing to throw into that story. it was just an example of ritchie needing to be the hero. >> what did he gain from killing her? what did he think he would gain? >> control. he wouldn't have to deal with angela any more. richie wilder, is responsible for angela's murder. and only richie wilder. >> richie's defense attorney countered that the murder

weapon was never found. he suggested that ritchie was somehow, set up. i think there is reasonable doubt here. i asked that you find richie wilder guilty. >> and the jury went out. and returned? in less than an hour. >> i have had simple theft cases that have taken longer. to decide, then this case did. >> we've a jury, find richie wilder, guilty of the crime of murder. >> guilty. richie's wife cindy resolved of tears in the courtroom. and then again later, in the hallway. >> he's a good man. he's a good husband. he would never do anything that would hurt his kids. none of it makes any sense to me at all. i know that i was home that night, i got up on a couple of occasions with my kids. when i got up, he was at home. >> sad, but still so loyal. keeping on clinging to that

long destroyed alibi. not uncommon, really. for a spouse too refused to an except an awful truth about her man. anyway, cindy was left to pick up the pieces. her sister abby, moved to minot to help. >> i just felt like she needed me as a sister and she needed the support. i've been a single mom for years, i know how hard it is to do it on your own. so i felt like i was going to do what i could to help her to bear that burden and to figure things out. >> and it helped. cindy went back to her teaching job. but even with abby there, she felt lonely. a certain kind of lonely. oh. >> coming up, growing suspicions about cindy. >> did she drive him there? was she inside the house? was she involved in this?

wilder guilty for murdering his ex wife angela. even after the verdict, his second wife, sidney, continue to stand by his man, insisting that he was no killer. cindy was about the rekindle a connection with a old friend and the story that she told him will come with a surprising twist. here again is keith morrison with prairie confidential. >> murder can have so many innocent victims, like the children. angela's and richie's forever deprived of both parents now. >> they have been with me for the past year, and they will continue to be with me. they need to know that there that is a good dad. >> stepmother cindy, the kindergartner teacher, so that she was doing her best in trying circumstances, raising a step kids, the children of the woman that her husband had just been convicted of murdering. she did get some help, mind you, from her sister, abby.

>> i saw that she was struggling and needed some help, trying to figure out the whole single parent thing. but, of course, abby had to wonder what happened that night, the night that ritchie murdered angela, human nature, really. >> i tried to ask her a few times. are you sure that he was home that night? >> the same questions that bothered the minot detectives, but seen stuck to her story. >> he didn't leave last night night. >> yes, he did. >> no, he didn't. >> as you can tell, they had their doubts about cindy. >> did she drive him there? was she inside the house? was she involved in this? >> no way to know. >> we did not have anything to go on. >> you put out your mind? >> we did. >> meanwhile, abby help the cindy with the kids and watched her sister grow even more sad. >> she did seem lonely.

she wanted someone to talk to. she wanted a companion. it seemed like she was dealing with the realization that her husband was not coming home. >> it wasn't necessarily romance that she was looking for, just a man to talk to, like the bartender that she once knew at the minot watering hole, cold, the original. his name was matt walters. him and cindy had met before she married richie in 2013. >> we would hang out on slow nights, two shots together. there was one night when we had a good, in-depth conversation. ever since then, she felt this connection. that is how she referred to it, this connection. >> the chief trust you? >> she seemed like it. >> they lost track of one another, after cindy married richie and had a little girl. >> but after the murder, cindy found matt on facebook. >> she said something like, i suppose you heard.

i said, heard what? she linked an article to richie being arrested. >> did you feel a bit sorry for? >> yeah, i felt really bad for. >> matt and some friends took sydney out for a drink at, where else, and talked about, you guessed it, richie's arrest. >> did she have any comment about his guilt or innocence? >> she insisted that he was home alone with her the all night and never left. i think that the only thing i ever said to her was, if that is not true, and you testified to that in court, you can un-up in-person. >> matt knew something firsthand about person. he had done a little more than a year behind bars himself in these early 20's for burglary, before turning his life around and go into work as an electrician. >> you warned her? >> yeah, i let her know that person is not a place that she wants to go to. >> anyway, that was a shoulder to cry on. >> she was going through a

crappy time. >> even at their matt moved to denver, they chatted online. >> one day, sydney said something very disturbing. >> we are talking about how richie got caught and going to prison. i said a knife is a stupid way to do something like that. she said, well, the knife was a backup, it was supposed to be a gun. >> wow, -- >> that was my response, wow. she wasn't the innocent bystander. she wasn't the innocent bystander, and the right thing is to let the people know. >> so matted. he called the minot police, who, by then, had all but given up on the cindy angle. >> there was a phone call into the general police department for nine. this individual had given his name and phone number and that he had information in regards to angela wilder homicide. >> so, would you do? >> we arranged a time for detective tyson eye to place a call and we heard him out. >> he seemed very credible.

he was somebody that had this bad gut feeling from conversations that he had with cindy that there was more to this. >> so detectives took the next step. they enlisted him as a confidential informant and gave him a name, see i dash 17 dash 001. i mean what's it like to be a confidential informant? >> during the time, it was kind of cool. it was kind of like what you see on tv. >> the arrangements, however, we're a little daunting. >> they came out and they asked me if i would be willing to come up there and wear a wire. >> what was it like to hear that? >> i was kind of stunned and dumbfounded for a second. and you know after a second of thought, if she was involved, the right thing was to go up there and help them. >> careful. you can never know when you set a trap, exactly what your catch. >> test, test, test. i'm almost there. >> coming up, cindy stay silent

paranoid, and i just gathered that if they put a wire on me and we started talking about this stuff, there was a chance that she would want to search me. >> he felt that it would be better to just go for a ride or go out and have his car wired. >> so police did just that. then hit a transmitter in the trunk so that the detectives could follow and listen in. >> test, test, test. >> 9:30 pm. matt picked up cindy at her house. >> has it gone? >> well, you know. kids are finally passed out. >> they want to a bar where matt turned on a phone app to capture the conversation while they weren't in the car. >> well, i'm gonna get a beer. >> i wanted us all to be caught to pull together. i hadn't seen her in years. >> he didn't push too hard, didn't probe. >> this is just my second drink. >> for now, he was an old friend, catching up, till, past midnight, then -- >> i drove her home and, you know, she didn't get out of my

car, which is good, but it got to the point, it seem like an hour in one where she wasn't saying anything. anything relevant. >> detectives good men and multi's, park no more than 30 feet away in the dark, we're desperately trying to stay awake. >> at some point, we both were probably thinking, okay, we're on our four. we're sitting in this darker. you're getting tired, you're getting exhausted, we've been listening for hours. >> and there's nothing there. >> and then all of a sudden, it happens. >> you know, i said, well, i should probably get going. and her body language changed and just the tone of the situation changed. it was pretty obvious that she was, that she was angry. >> angry? >> she seemed angry. >> angry about what? >> well, i wasn't sure, so i asked her. are you mad at your husband? >> no, like, i'm -- i'm proud of him, i'm just

pissed that he got caught, and that he got sloppy and impatient, and -- we had this thing, like planned for two years. >> planned for two years? what? >> it was almost like the floodgates opened and she got it all off of her chest at once. >> like he came on that night, and he said, it got sloppy. she fought back. he had to do what she had he had to do. she put up a good fight, like, she did. >> well, i'm sure, she's fighting for her life. >> she scratched his face like, and that's what got him to. if it was me, i would've gone back into our fingers off. i would've burned them. i would've lit the house on fire. >> what was it like to hear that? >> it was the hardest mental think that i've ever had to do. to hold back the urge to tell her to shut the -- up, that she sickening. that she's disgusting. >> he went psycho on her, because the hate and the anger.

>> yeah. >> and the frustration and i would totally would've done the same thing to. >> it's like i said before, and offices to politico somebody. >> he had a gun that was untraceable, but every time he took it, it kept jamming and i guess that night, it was old. i helped him clean up. he left again to dispose of the clothing and the weapon and everything. i thought we were like in the clear. >> do you think you are a horrible person or do you think it needed to be done? because now you've said bowed. >> i fully believe that it needed to be done. >> needed to be done, she said, as if murder was somehow a winning solution to their long running struggle over who got custody of the kids. and finally, remember how angela had told her fiancée before the murder that she was worried about being watched? angela was right to be worried. >> like, i helped him. like, i would leave, like when he worked nights, i would leave the house at midnight and sit outside her house in my vehicle,

seeing who came into the house. when her boyfriend left, where -- when -- yeah, we had this planned out. and he -- up. he did not clean the car good enough. one spot of blood in my car. >> when she said that, can you tell me what that was? like >> we are pretty excited. >> there were some high fives in the car. >> all right, let's call it a night. i'm the. your be. we will see each other again, right? >> it's up to you. >> maybe. >> run out and exhausted, matt rendezvoused with the detectives that the sleep in. >> well, we got back to the hotel, and we went into the room, and i said to him, is it too soon to help you? >> i was so drained. we called it a night. i won't back to my friends house that i was doing it. i couldn't sleep for two or three hours. i was exhausted, it was also surreal. it was a roll wind of disbelief

and shock and discuss, and i kept having graphic images of what angela went through during the murder. >> you did know angela? >> i didn't. >> a few days later, the detectives went to the school where cindy was a substitute teacher. third grade that day. >> we met with her privately in an office at the school. i showed her that i had the arrest warrant for her for being part of the homicide with angela. >> how she take it? >> she really didn't respond. she didn't cry. she didn't make any statements. >> oh but she would. such a surprise on the way. >> coming up. cindy says she was just bragging. >> a handful of things in that conversation are somewhat true, but for the most part, it's false and extremely exaggerated. >> but will anyone believe her? >> that was kind of a shocker in the courtroom that day, in fact, wasn't it?

sydney was arrested and headed to court to share a different version of her story. first, she talked to us, here is keith morrison with the conclusion of prairie confidential. >> cindy wilder was tiny, almost childlike, in her jail jumpsuit, barely five c, maybe 100 pounds, a trusted teacher of the very young and very innocent. >> reserve a hand. do you swear the statements about the make. >> and yet here she was in court, entering allegations a very big crime, a few shea truths, of lying to everyone, even those who love thermos. >> i felt betrayed because high felt sorry for her, and as a sister, i wanted to help her and then to find out that it all felt like a big lie, and i was pretreat and deceived. it was terrible. >> no doubt. she did say what she said on

those tapes with the confidential informant, matt walters. >> like if it was me, i would have gone back in color fingers off. i would've burned them. i want to let the house on fire. >> what did you think when you heard that, knowing there was a two-year-old child in the house at the time? >> i thought, well, those are strong words, that is a lot of hay. >> but was it? or was it something else altogether? a few days before that scene in court -- >> hello? >> yes, hi. >> this is cynthia wilder. >> we interviewed cindy by phone from the ward county jail in minot. how would she -- how could she explain all those terrible things that she said to matt, on tape? her answer was also her legal defense. >> i mean, i'm lonely, and i was trying to see if there could be any sort of relationship, and i was kind of trying to impress him. >> you are trying to impress him, did you say? >> yeah, because i know he has it a criminal history to, so i thought, you know, that would

be our connection, our common thing. >> so he said, i did all these terrible things, when he didn't really do them? >> i mean, a handful of things in that conversation are somewhat true, but for the most part, it's false and extremely exaggerated. >> what would be true out of that conversation? >> the fact that i knew about it after it happened. okay and you hit the fact that you knew about it? . >> i want to lose the case of my job. >> with the jury believe that cindy was really trying to impress a man with some made-up tough talk, certainly, the prosecutor did not buy it. >> if you're trying to impress a boy, you make up a story about being a state champion gymnast or diver, not about being an accomplice to murder. >> in any case, no jury would

have to decide. on a charge of conspiracy to commit murder, the prosecutor offered a deal. cindy wood spent 25 years in prison, then get out to resume her life. and sidney turned it down. she had a strategy of her own. she would take and our plea, meaning she plead guilty, not because she did it, but because a jury would likely find or guilty, and that way, she believed, the judge would impose a much lighter penalty. and in may, 2018, sydney's attorney appeal to judge stacey lassiter for leniency ethan's. ten years and now it was the judges turn. would she believe sydney's explanation? >> you were the one person who could have stopped this nightmare. you are the one person who could have intervene, who could have called law enforcement when richie wilder left her home. you are the one person who could have spared angela wilder's life.

you chose not to do so. i am here by remanding you to the north dakota department of corrections and rehabilitation as to count one conspiracy to commit murder, to a sentence of life imprisonment without the possibility of parole. >> life without parole. that was kind of a shocker in the courtroom that day, in fact, wasn't it? >> it was a surprise but, i mean, it's certainly, in my mind, well deserved. >> were you surprised? >> this judge is known for hearts and seeing, particularly where children are implicated. >> they certainly were in this one. >> absolutely. >> for cindy, not a flinch. from her sister? >> it almost feels like a death of someone in the family. everything changed. at least before, there was some sort of hope that, even a foot

was a long period of time, there is still the hope that, you know, we can make memories again and go on trips and spend time together outside of prison walls. and that's gone. >> but for angela's sister? >> she's a horrible person. she's exactly where she needs to be, and i'm so thankful that the judge saw her for the individual that she is, the monster that she is. >> and so our story ends with a family shattered, and matt walters? the summer grace decision to wear a wire. but he struggles. doing the right thing was not easy. >> basically, i'm responsible for ending another person's life in all meaningful ways, which is fine. she deserves it. but it's still kind of a hard thing to deal with the no you and it's someone's life. >> like you feel somehow it's on you? >> yeah, there's like a way on you. >> and angela will surely be

working as nurse by now, finally have achieved her lifelong ambition to care for people and make them well. >> she pops in my head, and i just think, oh, sad, because she would've been one heck of a nurse. >> that's all for this edition of dateline. i am natalie morales, thank you for watching. for watching i'm craig melvin. >> and i'm natalie morales. >> and this is dateline! >> during the middle of the night, i heard this noise. it sounded like someone was in the house. i opened up her door, and, i'm hearing things. >> your instincts were right. that something happened in the middle of the night. >> you think your child is safe in your home sleepi.
