she was burning the candle at both ends to make come true then, angela was murdered. investigators suspected the attack was personal. just when they thought it was case closed, turns out it was not. so, they said an elaborate trap, hoping to catch a killer. here is -- >> it was dark, the great central plane. luminous in the early hours of that friday the 13th of november. the small light winds shivered on flat, deserted streets. and knit to the freezing little t that the ruins of autumn, in north dakota. was there a muffled cry, the sound of a car making haste away no one heard. not a thing. it's a modest placed, 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? are >> 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, dad. toddler nearby. an investigation about to lead

fickle thing. like people sometimes are. is that why angela wilder's fiancée, chris was so angry? >> there was a history to this long before that november morning, in 2015, and far away from minot, north dakota. in alabama, angela met richie. at church, they were the best of friends as kids. after angela had a baby as a teenager, it was richie who scooped her up, married her adopted a little girl and before, long had a boy of their own. all witnessed by angela sister, crystal. >> she attended today guys who were funny. that were gentle, intelligent and really, richie was all of those things >> ritchie was in the air force. that's why they moved to minot, there was an airbase there that's 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, and still attended classes, and take her kids >> why did richina and gilles's life long bond rupture? who really knows? but there is curdled into a corrosive, toxic anger ritchie was court-martial, convicted of domestic abuse jumped out of the military. the divorce followed. but then, like the prairie wind, their affections shifted. richie remarried a small town north dakota girl named cindy who moved to minot and became a kindergarten teacher. soon, cindy and richie had a baby of their own angela got engaged to chris, and she had another baby as well. these two new families all settle down again or they might have, except for richie and angela's nasty custody battle. >> she said he is just fighting me all the time it's been

really hard with the kids. >> it was bad between those two scary >> i got a frantic phone call from her one morning, i was like, calm down, what's going? on >> she says, it's richie i just woke up, came out of my bedroom, went to my living room, and he sitting on my couch he looked at me and said, see i told you, i can get to if i wanted to >> is that what happened here? an angry ex-husbands revenge >> hello, are you? richie >> yes ma'am >> a few hours after the murder, after talking to angela's fiancée, chris. detectives goodman and multi's call russian for a top he didn't seem to know what was going on. >> i will tell you, angela is dead >> or really? >> yeah >> did he seemed upset by what it happened? >> he didn't, know >> that requisite? >> it did, yes >> he would have some reaction, it's a mother of a child >> that's what we would expect. >> their questions got tougher

>> did he have an alibi? >> he said he did >> did you work last night? >> 7-eleven >> would you after you left work? >> -- can anybody tell us when you go to? >> >> that is his new wife, the kindergarten teacher. cindy >> 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?

>> now. 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.

kept stabbing her. >> richie wilder had a news story. a new and shocking story that put him and his ex-wife, angela's bedroom. the night she was stabbed to death. but did he kill her? oh no, richie said. but who did? richie was finally ready to reveal the secret. to point the finger at the very man who had accused him. the killer? was angela's fiancée. chris. >> i said what's the -- are you doing man? >> but, to start at the beginning. richie said that chris found out angela was cheating on him as he worked his night shift at walmart. he wanted to catch her in the act. proof that she was an unfit mother. so they, chris and richie, would win custody of their respective kids. sounded good to richie. so, friday november 13th, doug to 15 am. richie told us that he picked chris up from walmart and drove him to the house.

they were supposed to catch her in the act of cheating on chris. >> when we open the door, it looked like there was two people in the bed. and when we pulled off the cover, i notice that was not a person. it was a body pillow. >> but maybe chris did not understand that, said richie. because he went crazy and started stabbing her. >> and i touched her neck to feel a pulse, because she was kind of -- as i touched her pulse, she leaned up and scratched my face. i grabbed her hands, and she was just like, i love you. >> that was why his face was scratched, said richie. and his dna was under her fingernails. anyway, afterward, said richie, he drove chris back to work and dropped him off at walmart. >> where did chris ride? >> in the passenger seat. >> the same spot in the car where that blood was found. angela's blood. >> when we first interviewed you, richie, why did you not tell us this? >> well, one, because he kept threatening my family.

he said if you tell anybody, i am going to kill your wife, i am going to kill your little one. >> it was quite a story. the only problem? walmart, where chris worked, had cameras everywhere. and it just so happened that detective goodman spent the night before, watching videos with richie. videos that kept witness of every movement, every minute. if chris left the store to kill his wife, then good men would not see him on any video shot between to 15 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 ritchie is telling us that he is 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. >> [inaudible] and i asked that you find richie wilder not 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 wet 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 suspicious about cindy. >> was she inside the house? was she involved in this?

>> and the secret revealed. >> wow. >> that was what i thought. >> when dateline continues was what i thought >> when dateline continues ♪ got my hair ♪ ♪ got my head ♪ ♪ got my brains ♪ ♪ got my ears ♪ ♪ got my heart ♪ ♪ got my soul ♪ ♪ got my mouth ♪ ♪ i got life ♪

commit murder, the prosecutor offered a deal. she would spend 25 years in prison, and then get out to resume her life. and cindy turned it down. she had a strategy of her own. she would take an all furred p plea. meaning she pled guilty not because she did it, because a jury would find her guilty, that way the judge would impose a lighter penalty. but in may 2015, who they appealed to the judge for a lean more lenient sentence. and now, it was the judges turn. which he believes in these explanation? >> you are the one person who could've stopped this nightmare. you're the one person who could've intervened. who could have called law enforcement when reggie left your home. you are the one person who could've spared her life. you chose not to do so.
