What happened here . I was utterly confused. So many different stories about what might have happened. He said many things that night. Maybe, someone could have shot something at the house. At one point, he said that there was 80 suicide. Police had their own theory. I thought, oh, man, theres something going on here. We dont see a lot of women that commit suicide, naked. Conrads stories were not adding up. Reporter but Something Else wasnt adding up, either. A key piece of evidence. We went to the house. And we walked in, and we think, ahha. Would a mistaken measurement send an innocent man to prison or free a guilty one . One suspect. So many stories. Only one of them could be true. Somethings going to break. And when it does, the truths going to be known. As night fell. Hello and welcome to dateline extra. Heidi and Conrad Truman had a special bond. A deep love. Envied by others. But one, tragic evening, a gunshot rang out. And in the blink of an eye, heidi was on the floor, clinging to life. Conrads behavior in the minutes and hours that followed would be hotly debated, for years. Detectives would focus on the grieving husband. But were they looking at the wrong man . Heres josh markowitz. Reporter they seem to inc incongruous. The soaring majesty of the mountains and the story of a beautiful woman, struck down in her youth. It was a lot of things. Tragic. Crushing. Stunning. But was it an accident . Or a suicide . Or a murder . Police felt they knew, but as most cops will tell you, both the evidence and the jury have their own stories to tell. And the answers not always so clear. Certainly, that is true for this story. And, quite possibly, for the woman at its heart. Her name . Heidi wagner. As the baby, she was favored. Everybody loved her. She could do no wrong. Autumn was one of heidis four sisters. She was just special. You know, shed walk into the room and she shes ready for that good time. Heidi grew up with no fewer than seven older siblings. Tell me about her, growing up. She was a funloving girl. She was rather shy, though, so heidi seemed like an appropriate name. Heidis mom, janet. The family would get together and we were kind of loud and boisterous and shed hide her face. Make no mistake, heidi was no pushover. She was kind of intimidating, actually. For being so small, you wouldnt think so. At just 20, heidi started working in the notentirely feminine gas and Chemical Industry just outside salt lake city. Sandy sanchez was one of heidis coworkers. We worked with hazardous chemicals and gases. Crazy things that you wouldnt expect a couple of girls to want to do. Heidi seemed to thrive. In a workplace that favored hardhats over heels. It was dangerous if you didnt follow the rules. In fact, quote from heidi, everything is dangerous. Its just what will kill you the quickest. To sandy, heidi became more than just a coworker. I considered her my best friend. She was a person that you knew never stab you in the back. She was the person that youd knew would always have your back. In person, she could be both sweet and salty. And that caught the attention of one of her colleagues, 25yearold Conrad Truman. I noticed her, first, in the hallway. Whatd you think . I thought she was cute and i noticed her hardhat and they have a little personality. Her stickers. You know, and hers said its all about me. Deal with it. And i was kind of thinking this girls kind of a feisty girl. Soon, conrad asked heidi out on a date. Im not that type, usually. I dont get superserious, right off the bat. But it was it was almost like we were inseparable, after that. That first night . Yeah. Yeah. We would go to the range and shoot in the hills. Heidi knew how to handle a handgun . Yes. One year into their courtship, conrad decided to pop the question. In true utah form, he chose a mountain on which to do it. She have any idea it was coming . No. I got on one knee and asked her and she just said yes, right off the bat. She couldnt believe it when her little brother first introduced heidi to the family. I was actually really sort of surprised when i first met her. Like, how did he land that girl . They just seemed to be such a great match. You saw a love and chemistry there. Oh, it was almost awkward. They were, definitely, an enviable couple. A year later came a wedding. It was amazing. We went up on a lift, a chair lift, and then all the guests left down these slides. So it was just so them. They said their vows, and he is kind of doing this champion pose like he was just everything was right with the world. The enviable couple was just starting out with a future as bright as their smiles. Until, that is, a sunday evening in september, 2012. Three years after the trumans were married. Tell me about that day. That day was like just like any other day. As night fell, heidi decided to take a bath. Conrad said he went to the kitchen to get something to eat. As he fixed himself a sandwich, he said he heard a noise coming from the direction of the bathroom. It was like the new years poppers or the halloween poppers. Where you can pull two strings or you can pull one. And confetti and stuff comes out. Thats when conrad said he turned and saw heidi standing there, in the hallway, naked. She wasnt talking. She wasnt talking, at all. She was coughing. She was heaving. And she was bleeding. She was bleeding out of her nou mouth and her nose. I needed to call 911, immediately. An unimaginably shocking scene. Heidi on the Kitchen Floor in a pool of her own blood. Conrad, on the phone, pleading for help. It was bad to begin with, and it got so much worse. As you will learn, truer words may never have been spoken. Im asking like, conrad, whats going on . He said, i dont know what happened. Everything was just different answers and different theories. Different, little things. A search for answers and a race to save heidi. When as night fell continues. When as night fel continues. Daily anoro. Copd tries to say, go this way.

Something was wrong at the truman house. She came out of the shower and i heard a pop. And theres theres blood. I have officers and paramedics on the way. Okay . The 911 call came into the orem, utah, Police Department at about 11 00 p. M. , that september night, back in 2012. We got a call of a gunshot wound or some sort of injury. Sergeant bill crook, now retired, went to the truman home. So we all kind of rushed to our cars and headed that direction with lights and sirens. Reporter on the other end of the phone was conrad, kneeling on his Kitchen Floor, covered in blood and consumed by panic. It was devastating. It was a nightmare. You cant seen explain it. Reporter with one hand, he held the phone. With the other, his bleeding wife. It was so hard. When its your lfboved one like that, i had no i just did the best i could to try to keep her breathing. Reporter by then, conrad said he realized heidi had been shot in the head. When you went to heidi, did you see a gun . No. Reporter he remembered the pop he had heard. And wondered if a stray bullet might have come through the bathroom window, and hit heidi. I was trying to think of the noise, and how it wasnt very loud. And, you know, maybe, someone could have shot something at the house. Reporter it seemed farfetched. But, he said, neighborhood vandals had recently been shooting the back of his house with paintballs. I was utterly confused. Reporter within minutes, sergeant crook arrived. Conrad, by now, had moved to the doorway of his home to wave crook down. He had blood on his hands and he was screaming and shrieking. Conrad led the sergeant through the front door, up the stairs, and then, into a scene straight from a horror movie. I could see heidi laying there. She was naked. Blood everywhere. Just right at the top of the stairs. Just this horrific scene. Whats conrad doing . Well, he is screaming and hes yelling. Reporter and as these Police Photos make clear, covered in blood. Im asking him, like, conrad, whats going on . What happened here . He said she was in the bathroom. You know, and just, i dont know what happened. Everything was just different answers and different theories. Different, little things. Reporter right away, crook went to check one of those theories. A stray bullet. Perhaps, coming through the bathroom window. The windows closed. Theres no bullet hole. Nothing to indicate that anybody fired a shot from outside. Thats correct. Reporter crook returned to the kitchen and thats when he discovered a gun, lying on the Kitchen Floor. What did you think had happened . Honestly, i didnt know. Reporter was this an accident . An attempted suicide . Or something far more sinister . At least for now, those answers would have to wait. Heidi was clinging to life. My focus, at that time, was, honestly, was to help heidi. Paramedics took heidi to a nearby hospital. Conrad followed, in a police cruiser. A dash cam recorded the absolute desperation in his voice. This is not happening. This is really not happening. I really dont understand any of this. This is so crazy. Reporter about an hour after conrad arrived, hospital staff delivered the devastating news. Heidi wagnertruman could not be saved. It was pain. It was misery. It was why . How . Reporter in a neighboring town, heidis mother, janet, would soon agonize over those very same questions. It was after midnight when two Police Officers came to her door. What must that be like . The most horrendous thing, ever. And i would never want anybody to have to feel that, and that pain, that agony, of knowing that your daughter, for whatever reason, is dead. Is gone. Reporter the officers wouldnt give janet any details. Only, where her daughter had been taken. I am driving down to the hospital. And i make a comment to my daughter. I go, you know, autumn, as hard as it is that we lost heidi, were going to have to be supporting conrad because he must be overwhelmed with grief. Reporter conrads sister, collette, was thinking the same thing as she raced to the hospital. What kind of condition was your brother in, then . He was just a total wreck. Just absolutely hysterical. Didnt know how it could have happened. Reporter no one did. But back at the truman home, sergeant crook had started analyzing the evidence. And was, already, developing a theory. I thought, oh, man, theres something going on here. You got a feeling. I got a feeling, yes. It wasnt just me. Everybody was kind of looking around like this theres something wrong here. We need a detective. Coming up. Was it an accident . Suicide . Shes completely naked. We dont see a lot of women that commit suicide, naked. Thats not common. Or Something Else .

But im sure whatever youve been working on is equally impressive. We are farmers. Bumpadum, bumbumbumbum as the sun inched above the mountains, questions swirled at their base. How did heidi truman wind up on her Kitchen Floor, shot in the head . For sure, police were wondering about her husband. After all, Conrad Truman was in the house when heidi was shot. And there was no evidence of an intruder. I felt like they thought i did something. Reporter soon after he arrived at the scene, sergeant bill crook did begin to have his suspicions. Were telling him, conrad, back off. The paramedics are here. Back off. And he wouldnt. He was, what, moving around, keeping paramedics from being at the body . Yes, sir. Reporter there were other scenarios that needed to be explored, like accident and suicide. Thats where thendetective tom wallace came in. There have been a number of theories. We, obviously, are going to exhaust them. Thats going to happen. The medical examiner didnt make wallaces job any easier. His preliminary finding, heidis manner of death could not be determined. So, wallace tackled each theory, one by one. Accident seemed hard to believe. Thanks to conrad, heidi had firearms experience. Can you think of any way it could have been an accident . No, heidi wouldnt have been so careless. Reporter so what about suicide . Shes completely naked. We dont see a lot of women that commit suicide, naked. Thats not common. Did you find anybody that heidi had spoken to about suicide . Or about being depressed . No. Reporter neither, heidis mother janet, nor her sister autumn, could imagine taking her own life. Heidi would never do that. In fact, heidi was against that. She had a friend who committed suicide and she thought it was selfish and, in other words, dumb. Heidi ever tell you she was depressed . No. Ever act depressed . No, she was probably one of my happiest, most upbeat kids. That left wallace with homicide and it put conrad back in the police crosshairs. Wallace decided to speak to the officers, first, on the scene about their experience with conrad. Everyone felt his behavior was odd. He is yelling but its its a violent yelling. Hes like, if you dont save her, im going to [ bleep ] kill you. Crook found those threats so alarming, he took out his phone to record them. Youre going to die. Everyone in your lifes going to die, if she dies. It could just be the way this guy reacts to trauma. But im telling you, it was a red flag, at that time. Also, a red flag. Conrad was drunk. He admitted he and heidi had been drinking earlier that night. I could see in his eyes the redness. Red flag number three. Conrad told crook he and heidi had been arguing. A minor dustup, he said. No big deal. But enough for heidi to draw a bath and ask to be left alone. She went and locked herself in the bathroom. And then, he details how he picked the lock and went in the bathroom. And then, she kicked him out. To me, thats another its its just more proof of there was an argument, a bigger argument. Reporter as for the location of the gun, itself, that, too, was suspicious. That guns how far from heidi . Oh, i would say eight feet, ten feet, maybe. Its far enough away that it wasnt a normal, like, if she shoots herself and falls to the glou ground type of thing. Later that morning, police ask conrad to come to the station for more questioning. They can say whatever they want but i did not hurt anyone. And i know that. Bottom of my heart, i did not hurt my wife. Heidis family thought otherwise. After finally learning from police the details of how heidi died. The minute i heard how she died, i knew he did it. Sounds like he had a temper, and he was very intoxicated. And he did something that, perhaps, he didnt plan. I just knew he did it. Reporter detective wallace, next, pored over conrads statements to police about what happened that night. As wallace saw it, conrads story went like this. Conrad was in the kitchen. Heidi was in the bathroom. At some point, conrad heard a pop. And when he turned, he saw heidi standing somewhere between the kitchen and the bathroom hallway, bleeding. And he either runs over and catches her. Or she falls down. Reporter wallace, then, went back to the truman home. Making detailed measurements of the kitchen and surrounding rooms. He wanted to see if conrads story checked out. His conclusion. It did not. Her bodys at the top of the staircase. It doesnt add up that she would have traveled the distance hes saying she would have gone, and then fallen at that location. It was hard for wallace to believe heidi could have traveled from the bathroom to the top of the stairs, after sustaining such a severe head wound. She would have fallen, immediately, to the ground. Wallace shared his findings with assistant District Attorney craig johnson. Johnson agreed. Everything pointed to conrad. Why would Conrad Truman want to kill his wife . Under the circumstances, id say the motive was just based on this heatofpassion argument that they were having. Alcohol, a fight, and guns. Thats where we got murder. Reporter at the same time, johnson was still reluctant to press charges. Remember, the states own medical examiner couldnt say whether heidis d
