As soon as class was over she was gone. Back home . Yes. Thats where they found her. My girl is not answering the phone. The officers could see a lot of blood.

Did he try to point the finger at anybody else . He did. Angilas ex husband. The ex had an alibi to. He came off as very calm and collected. And there was Something Else missing. We got a phone call until someone found it. They asked me if i would be willing to come up there and wear a wire. One old friend talking to another. This is just my second drink. About a secret she was dying to share. I think she was almost proud of the whole thing. A case where the biggest twist came after the verdict. Wow that was my response, wow hello and welcome to dateline. Working mom Angila Wilder dreamed of 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 just when they thought it was cased close, 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, on the Great Central plains. Moonless, in the early hours that friday the 13th of november. A small light wind shivered along flat deserted streets, and nipped the freezing little teeth of the ruins of autumn in minot, north dakota. Was there a muffled sound of a cry, no one heard. Not a thing. Its a modest place, modest in a good way. And uncommonly friendly, comparatively speaking, of course. Its comfortable. Its a family community. North dakota nice, maybe an old fashion 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 that morning at Minot State University department of nursing, professor diane shull wondered why one of her students hadnt shown up for an 11 am exam. Before we all started taking the test i said has anybody heard from angila . Angila was this woman. My name is Angila Wilder im a Student Nurse with and i will be investigating your cardiovascular system today. She was a sweet little southern girl. Always miss diane, yes maam, no maam. I let the doctor know and he will be with you shortly. Angila wilder was an 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, you know, who are not feeling well and then thats when i just told her yes is expected to come to class but if she couldnt she needed to call and let me know and we would just make other arrangements. But that morning . No call. No angila. Was she ill . Class was over. Before one of dianes students dropped a kind of bombshell. She said, well, i think it was angilas house where there was police tape around it, a lot of people in hazmat suits. And indeed it was angilas house. This little place next to a lutheran church, across the street from that elementary school. It was angilas fiancee home from a night shift who called 911. I just got home, my back door is kicked in, and my girl isnt answering the phone. My sons inside with her and everything. Im about to go in and see what is going on. Okay, why dont you just wait for officers. Ill get them over there. So, the fiancee stayed outside. The officers went in. The house was neat, tidy. They found the twoyearold unharmed. They went down the hall looked into the next bedroom, and there she was. Very dead. I didnt know at the time exactly how many times she had been stabbed but i knew that it was vicious. Why not Police DetectiveSergeant Dave goodman. How many eventually did you found out . Somewhere near 40. And there was the fiancee, 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 that he was obviously concerned about that. If that was me, i think i wouldve rushed in there to see what was going on with my family. And i say that to, of course, until you experienced that yourself i guess none of us know how we would react. Still, good mens Detectives Instincts kicked in, so what if some 911 dispatcher told him to wait, wouldnt innocent, worried parents really do that . It was suspicious. Why did angilas fiancee Chris Stay Outside . And, had he really been at work all night as he said he was . They took him downtown to the first of several interviews. Where goodman and his partner detective Sergeant Chris mathias sized him up. His name was chris jackson. How did he present . He was calm, he was crying, he was upset. He was mad. Where was he that night . Chris said angila drove him to work at walmart. Dropped him off before 11 pm. And i kissed her, and i said i love you, sweetheart. Drive safe, have a good night. Angila was nervous, he said, afraid to be left alone. Why did he say she was anxious during the night . The night before she thought that she had heard somebody messing at the front door of the residence. She felt like she was being watched. So said chris he called, and he texted her repeatedly. But after 2 am, he said, she didnt pick up when he called. And he figured she had fallen asleep. But no, she wasnt 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 the piece of [bleep] who did it, god i hope [bleep] they [ bleep ]. Richie, who was he . A pregnant young mom dead, her toddler nearby. An investigation about to lead it to even darker discoveries. Coming up her fingernails were broken off. Detectives talk to richie. What happened to your face . Where . Right here . You got a scratch on your face. Are they getting closer or getting away . Did he have an alibi . He said he did. When dateline continues. Chevy silverado has what it takes to do it all.

The wind on the prairie is a when pain comes for you, Keith Morrison voiceover the wind fickle thing. Like people sometimes are. Is that why Angila Wilders fiancee chris was so angry . Richie is probably the [bleep] piece of [bleep] who did it. There was a history to this, long before the november morning in 2015 and far away from minot, north dakota, in alabama, angila met richie at church. They were the best of friends as kids, 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, krystal. She tends to date guys who were funny, gentle that were intelligent and really ritchie was all of those things. Richie was in the air force, thats why they moved to minot, the airbase there. And thats where angila 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 angilas lifelong bond rupture . Who really knows. But theres curdled into a corrosive, toxic anger. Richie was court marshaled, convicted of domestic abuse, drummed out of the military. A divorce followed. But then, like the prairie wind, their affection shifted. Richie remarried, small town north dakota girl called cyndi who had moved to minot and became a Kindergarten Teacher. And soon cyndi and richie had a baby of their own. And angila got engaged to chris and she had another baby too. And these two new families all settled down again, or they might have, except for rich in angeles nasty custody battle. She said he was fighting me all the time, its 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 is going on . And she said its richie. I just woke up, came out of my bedroom, went into my living room and he is sitting on my couch, and looked at me and said see i told you i can get to you if i wanted to. Is that what happened here, an angry exhusbands revenge . Hello. Are you richie . Yes, maam. A few hours after the murder, pat her talking to angilas fiancee, chris, Detectives Goodman and mathias called routine for a top. But he didnt seem to know what was going on. And ill tell you, angilas dead. , oh really . Yes. Did he seem upset by what had happened . He didnt, no. That strike you as odd . It did, yes. He would want to have some reaction, the mother of his child. Thats what we would expect. Their questions got tougher. Did you kill her . No. No . No. Im 100 percent truthful. Did he have an alibi . He said he did. Did you work last night . From 7 to 11 yes, maam. Where do you go after you left work . Straight home. Can anybody tell us what time you got home . Yes, cyndi. That is, his new wife, the Kindergarten Teacher. She confirmed that when she woke up for the baby during the night, richie was beside her in bed. He was home, the three times that i was up. If thats the truth, cyndi, thats fine, i mean maybe he was home during those three times that you were up during the night. Is that possible, sure. What do you know about this . I dont know anything. So, maybe the detectives could get some evidence from the crime scene techs who told them angila had tried to fight off her killer. Her fingernails were broken off, it appeared that the assault actually occurred while she was in bed and ended up on the floor next to the bed. Your dna is not gonna show up anywhere on her . No, its not possible. I wasnt even there. Gonna show up under her fingernails . No. But, they couldnt help but see the scratch. What happened to your face . Where . Right here . You have a scratch on your face. He had a story that he had been wrestling with his younger son and that he had gotten scratched. Police also in putting two cars driven by richie and his wife and in one, of small spot of something dark brown. On the inside of the door. Visible to the naked eye but not obvious that 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 couldnt believe it. That spot in rishis vehicle, it was indeed blood. Angilas 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, material found under angeles fingernails. About a week later we heard back on the fingernail clippings and that came back to richie and we said okay, lets 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 for the murder of angila. Richie junior was charged with murder, he soon pleaded not guilty. We offered an interview to him, and he didnt want to talk. He went to jail. Then, a couple of months later. Hi richard, do you remember us . Detective mateo, Detective Goodman.

Richie said chris had discovered angila was cheating on him while he worked his night shift at walmart, he wanted to catch her in the act, prove 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, 2 15 a. M. Richie told us that he picked chris up from walmart, that he drove him to the house, they were supposed to catch her in the act of cheating on chris. When we opened the door, it looked like there were two people in the bed, you know . And of course we pulled the cover, and i noticed that it wasnt a person, it was a blanket. Chris didnt understand that, said richie, because he said he went crazy in started stabbing her. I went over and i touched her neck to fill her pulse because she was kind of like and i touched her pulse and she leaned up and like scratch the mess out of my face, i grabbed her hands, she just said i love you. That was why his face was scratched said richie and his dna was under her fingernails. Anyway, afterwards which he said he drove chris back to work and drop them off at walmart. And where the chris ride . In the passenger seat. The same side of the car where the spot of blood was found. Angilas blood. When we first interviewed you, richie, why did you not tell us this .
