Thought you heard somebody messing at the front door of the residence, she thought she was being watched. All the wounds she had to her body, it was a very angry attack. A Nursing Student with three children. Nobody was busier than angila. And that is where they found her. The officers could see a lot of blood. The officers thought her boyfriends behavior seemed odd. People thought there was something suspicious about it. Buddy had an alibi. Did he try to point the finger at Somebody Else . He did. Her exhusband. He had an alibi, too. And there was Something Else missing. We got a phone call. Until someone found it. Just one old friend talking to another. About a secret she was dying to share. I think she was almost proud of the whole thing. A case for the biggest swiss came after the verdict. That was my response. Wow. Hello and welcome to dateline. Working mom Angila Wilder came to becoming a nurse and was burning the candle at both ends to make it come true. Then angila was murdered. Investigators suspected the attack was personal and when they thought it was case close, it turns out it was not. So they set an elaborate trap hoping to catch a killer. Here is Keith Morrison with prairie confidential. It was dark. Moonless and nearly that morning. Was there a muffled cry . The sound of a Car Making Haste away . No one heard. Not a thing. Its a modest place, minot, modest in a good way. And uncommonly friendly. Comparatively speaking, of course. It is a family community. North dakota nice may be an oldfashioned phrase but still fits. People who have been around a long time to 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 that morning at Minot University department of nursing, a professor wondered why one of her students had not shown up for an exam. Before we started taking the test, i said, has anyone heard from angila . Angila was this one. She was a sweet little southern girl. Always yes, maam and no, maam. Angila wilder was an addition to a Nursing Student a mother of three who just days before revealed to her professor that she was pregnant. Did you have any advice for her . We talked about how stressful school is and we talked about her not feeling well and that is when i told her, yes, she is expected to come to class, but if she couldnt, she needs to call and we would make other arrangements. That morning, no call. No angila. Was she killed . Class was over before one of her students dropped a bombshell. She said, i think it was angilas house when i came to school but there is police tape around it and a lot of people get hazmat suits. Indeed it was angilas house. This place to Lutheran Church across the street from the Elementary School. It was angilas fiance home from the night shift to called 911. I just got home and the back door is kicked in. My girl aint answering the phone. My son is inside with her. Im going to go inside and see what that [ bleep ] is going on. In so, the fiance date outside. The officers went in. The house was neat, tidy and they found a 2yearold unharmed. They went down the hall, looked in the next bedroom and there she was. Very dead. I did not know at the time how many times she was stabbed but i knew it was vicious. Mina Police Sergeant david goodman. Ck what story did he tell about coming home . He reported he was at work all night and when he arrived home he found the back door kicked open. He said that he was obviously concerned about that. If that was me, i think i would have rushed in their to see what was going on with my family. I say that, to. Of course, until you experience that yourself, none of us know how we would react. Still, his instinct kicked in. So what if a dispatcher told him to wait. When an innocent worried parent really do that . It was suspicious. Why did angilas fiance Chris Stay Outside . And had he really been at work all night and he said he was . They took him downtown for the first of several interviews were goodman and his partner to 22. Angila said he drove him to work and dropped him off of her 11 00 p. M. I kissed her and i said i love you, sweetheart. Drive safe. Have a good night. Angila was nervous, he said. Afraid to be alone. The night before she thought she heard somebody messing at the front door of the residence. She thought she was being watched. In so, chris called and texted e her repeatedly. But after 2 00 a. M. He said she did not pick up when he called. He figured she had fallen asleep. But no, she wasnt sleeping. But who killed her . H 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 [ bleep ] who did it [ bleep ]. Got i hope [ bleep ]. Richie . Who was he . A pregnant mom dad and her child lived nearby. An investigation about to leave to darker discoveries. Coming up, her fingernails were broken up. Detectives talk to richie.

For a great low rate, Keith Morrison voiceover the wind on the prairie is a fickle thing, will wind on the prairie is a fickle thing. Like people sometimes are. Is that why Angila Wilders fiance chris was so angry . There was a history to this. Long before that november morning in 2015 and are away from minot, north dakota, and alabama, angila met richie at church. They were the best of friends as kids and after angila 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 angilas sister crystal. She tended to date guys that were funny and gentle. That were intelligent. And, really, richie was all those things. Richie was in the air force. That is why they moved to minot. And that is where angila pursued her dream of becoming a nurse. She took classes whenever she could. She would have two jobs at a time and still attend classes and take care of her kids. Why do richie and angilas lifelong bond rupture . Who really knows . But theres curdled into a corrosive anger. Richie was courtmartialed and convicted of domestic abuse. Kicked out of the military and a divorce followed. Then, like the prairie wind, their affection shifted and Richie Remarried A Small Town north dakota girl named cyndi who moved to minot and was a Kindergarten Teacher soon cyndi and richie had a baby of their own and angila got engaged to chris and she had another baby, too. These two new families all settled down again or they might have except for richie and angilas nasty custody battle. She said he is fighting me all the time and its bar harbor the kid it was that between those two. Scary. I got a frantic phone call from her one morning and i was like, calm down. Whats going on . She said, its richie. I went into The Living Room and hes sitting on my couch and looked at me and said, see, i can get you if i wanted to. Is that what happened here . And angry exhusbands revenge . A few hours after the murder and talking to angilas fiance chris, Detective Goodman and mattice called richie and for a talk that he didnt seem to know what was going on. Did he seem upset by what happened . He didnt, no. Did that strike you as odd . It did, yes. That he would have some reaction. It was the mother of his child that is what we would expect. Their questions got tougher. Did he have an alibi . He said he did. Did you work last night . From 7 00 to 11 00 where did you go after work . Straight home. Can anybody tell us what time you got home . Yes. Cyndi. That is his new wife, the Kindergarten Teacher who confirmed and she woke up for the baby during the night richie was beside her in bed. Maybe he was home. Is that possible . Sure. But what do you know about this . In so, maybe the detectives could get some evidence from the Crime Scene Technicians who told them angila try to fight off her killer. Her fingernails were broken off. Appeared the assault occurred while she was in bed and ended up on the floor next to the bed. Your dna will not shop and they were on her . No. Would it show up under her fingernails . But they could not help but see a scratch. What happened to your face . He had a story that he had been wrestling with his younger son and that is how he got scratch. Police impounded two cars driven by richie and his wife and in one a small spot of something. Dark brown on the inside of the door. Visible to the naked eye but not obvious it was blood. Enough suspicious for them to collect it. And when the lab called back a few weeks later with his, well, it was quite a moment. We were excited. We could not believe it. That spot in richies vehicle was indeed blood. Angilas blood. We ended up standing up during the Conference Call and hugging. We were so excited to get that news. But, no arrest, not yet. Not until more results came in on material found under angilas fingernails. A week later we heard about the fingernail clippings and that came back to richie and we said, okay. Lets go get him. And they did. We found him at a local gym. We told him that we have an Arrest Warrant for the murder of angila. He was charged with murder and pleaded not guilty. We offered an interview to him but he did not want to talk. He went to jail. Then, a couple months later, richie asked her seat the detectives again. Because he was finally ready to tell the truth. And blow the whistle on his accomplice. Wait. Accomplice . Coming up. Richie story and why he says he kept it secret. When dateline continues. Business. Its not a ninetofive proposition.

He kept stabbing her. Richie wilder jr. Had a new story. A new shocking story that put him and his exwife angilas bedroom the night she was stabbed to death. But did he kill her . Oh, no, richie said. So who did . Richie was finally ready to reveal the secret to point the finger at that very man who first accused him. The killer was angilas fiance chris. But to start from the beginning. Richie said chris discovered angila was cheating on him while he worked his night shift at walmart. He wanted to catch her in the act. Who fruit she was an unfit mother so they chris and richie could win custody of their respective kids. Sounded good to richie so friday, november 13th, 2 15 a. M. Richie said he picked up chris from walmart and drove him to the house. They were supposed to catch her in the act of treating gents up cheating on chris. The first thing i noticed is it wasnt a person. Maybe chris didnt understand that, said richie, because he went crazy and started stabbing her. I checked her for a pulse. Like, she scratch my face. I grabbed her hands and she said, i love you. That is why is faced with scratch scratch said richie. He dropped chris back off at walmart. The same side of the car where that spot of blood was found. Angilas blood. When we first interviewed you , why did you not tell us this . One, because he kept threatening my family. You tell anybody and i will kill your wife and your little one. It was quite a story that the only problem, walmart where chris worked has cameras everywhere. And it just so happened that Detective Goodman spent most of the night watching videos. Videos that kept witness of every movement, every minute. If chris left the store to kill his wife, then goodman would not find him on any video shot between 2 15 i am at 3 00 a. M. 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 richie is telling us he is stabbing angila. In fact, the only time chris briefly left the store was his scheduled breaks. He couldnt have taken part in such a game with richie . He couldnt and we knew that. Goodman held back as richies told this tale and then. Chris did not leave walmart. I know he did because i picked them up. I know he didnt because i watched him on video. Minutes later, Richie Wilder, his bluff called, simply folded. So when Richie Wilders murder trial started a few months later. The evidence shows. The prosecutor was confident. I thought i had a strong case. My strategy was to present the crime scene and physical evidence and present richies multiple stories about how this went down. Straightforward enough. As richie listened, his wife cyndi dutifully seated near the defense table, the prosecutor called witnesses who told the jury about angilas blood in one of richies cars. Dna under his fingernails and the changing story richie told. She leaned up and like scratch my face. I grabbed her hands and she was like, i love you. Up to that point i was thinking he might be able to convince a jury but when he got to the point where Angila Sat Up and that, richie, i love you. It was done. It was done for me. Its just such an incredible thing to throw into that story. It was an example of richie needing to be the hero. What did he gain from killing her . Or think he would gain . Control. He wouldnt have to deal with angila anymore. He is responsible for angilas murder. And only Richie Wilder. S Defense Attorney countered that the Murder Weapon was never found and suggested richie was somehow set up. I think there is reasonable doubt here and i asked that you find Richie Wilder guilty. The jury went out. I returned in less than an hour. I have had theft cases that have taken longer to decide then this case did. We the jury find the defendant guilty of the crime of murder. Guilty. Richies wife cyndi dissolved into tears in the courtroom. Then, again, later in the hallway. Hes a good man. Hes a good husband. He would never do anything to hurt his kids. None of it makes any sense at all. I know i was home that night. I got up on a couple
