Police zero in on three fellow students. The dead girls friend. A small group of shelleys fellow students. Had a budding artist designed a seemingly perfect murder . There was the boyfriend, fascinated with weapons. He had daggers. Knives. Swords. Who collects that kind of stuff . Reporter there was the guy always hoping to get her attention. Trying to corner her in the hallways at school. Texting her on the phone. Shes like, hes really weirding me out. Reporter but maybe the brutality of the crime pointed to the roommate. Something like a lover would do. A spurned lover. Absolutely. Shelly nance was a shy girl. A budding artist who greatest pleasure was to sit in her room and draw. With thattal entd. She earned a scholarship to the Art Institute of dallas. She was thriving. Then, the unthinkable happened. Shelly was stabbed to death. And investigatored zero in on three possible suspects. One harbored a dark obsession fuelled by jealousy. Once there was a quiet little girl. In a quiet little town. Who liked to draw. She drew the butterflies that floated quiet like her. Around texas. Spelled just like the country. But they pronounce it italy. She drew a butterfly in her art class in elementary school. And all the little girls are like thats so good. Draw me one. Sa michelle nance. Everybody culled her shelly. And her mother loves to tell this story. Everybody was just so impressed with her butterfly. Ill be an artist. I think i can do this. She just started honing her artistic talent from that point. And draw everything. Anything. Everything. She loved to draw. And draw and draw. Shelly was different. From the other girls at school and home. Said her dad. The other two girls we couldnt keep in the house. She didnt want to go out of the house. She was perfectly happy to be at home on the weekend. Staying alone time. By herself. Which as you can imagine didnt make her very popular in the intensely social world of growing up. It didnt seem to matter much to shelly. They had them write an epilogue for the seniors. And she wrote you laugh at me because im different. I laugh at you because youre all the same. She wasnt like you two . No. Opposite. These are her sisters. She got in trouble. Shelly however did not raise hell. Not ever. She was very smart. Nonathletic. Didnt like athletics. That was our department. Just very shy. She sit in her room and read a book. Play video games. Never had to worry about her. She wasnt into like tattoos and piercings. And alcohol. And sex for sure. She avoid td majority of everything that could have gotten her into trouble. I was happy because of that. When she was a senior. Her teachers suggested she enter an art contest. Sponsored by the Art Institute of dallas. Shes like ot not that gad. The art teacher said you are. And she won. The same piece of art they took and put in the national competition. And it won her fourth place there. 13,000. Towards a scholarship. Thats remarkable. This is an a major talent. She was so excited about getting to go. Reporter the Art Institute of dallas is an urban school. Everything about it and around it as different as can be from little italy, 45 miles and a whole world away. But here, finally, was a world in which shelley felt like she belonged. Just being around people that had her same objectives and the boys which never paid attention to her in high school. Noticed her in college. She knew her stuff. This is what she wanted to do. She wasnt home sick. And i said okay. It was only an hour drive away. Her first year was just fine. So in september 2019 when she was in year two of the circle of friend and pa boyfriend. Her parents felt free to set off on a Real Adventure alone. Far from home. Just the two of them. A road trip to Yellow Stone National park. More than 1,400 miles up the interstate from italy. She was texting her on the phone. Were leaving texas now. And she sent it to each girl. Rachel and sean responded immediately. No word from shelly. We thought shes probably still sleep. She departmeidnt have class to. That wasnt unusual. Later in the the evening we thought something might be wrong. We hadnt heard from her. That wasnt like her. Its torture. She thought something was wrong. I what would happen to shelly . She never goes anywhere. She stays in the room. She goes out when she has to. So, the next morning when she hasnt called. We both got worried. The first thing the next morning, she called the Art Institute. To find out if she was in class. And actually they well, they wouldnt go check on her. She has a break. Then, they phone shellys sister. I told her i was like stop worrying about it. Shes 20 yearold. She doesnt want to talk to her mom. I didnt think anything bad would happen. I brushed it off. They kept driving. They were almost 1,000 miles from dallas. Thats when the School Called back. They sent somebody to the classroom. And she wasnt there. I was ready to turn around i knew something was wrong. Relief. Someone from the school ran into her roommate. She said i saw her last night. At the room. She was fine. Relief didnt last.

They called the school to check on her. And were told she was safe. Then the next morning, the School Called back. The nances Worst Nightmare was about to come true. She assured School Officials her roommate was fine. Shellys parents couldnt shake the feeling something was horribly wrong. She went home she found her. And she wasnt all right. No, she was not. Reporter the School Called shelleys parents yet again. Were on the highway and about 200 miles from our destination in the mountains. And phone reception was really bad. Reporter so, through the static, she couldnt tell. Was she hearing or imagining the words . And she said, your daughters been found in blood and then the phone went dead and id lost reception at that point. Reporter daughters been found in blood. Yeah. I was asking him, what does that mean . But i knew what it meant. I just didnt wanna accept it. The only thing that made sense was a Sexual Assault. Thats all i could think of because she didnt have any money. She didnt have any enemies. No. That we knew of. Reporter what is that like driving through the mountains so far away and you get that call . Panic. I wanted him to stop the truck. We were in the middle of the freeway. There was no place to cross. I wanted him to cut across the median and go back. We needed to get back. Not that we could do anything, but we shouldve been there. We shouldve been there. It kind of feels like your guts were kicked out from the inside. Thats about the best description i can it it hurts your whole soul. Reporter as they raced back toward texas, cynthias cell service finally cleared. She called the police and got the confirmation. Shelley was dead. So, again, she phoned shauna. I had to tell her her little sister was dead on the phone. I needed somebody to be there, to be my be me in my place. To be, you know, there if the Police Needed to ask questions and stuff. Somebody needed to be there. So i called her. And of course, i hated to devastate her that way over the phone, but she had to know. And i just hit the floor. I couldnt stand up, couldnt do anything, couldnt talk, just shocked. Reporter did you have any idea what happened . None. I got to the scene first cause i lived closest to her. It was like a scene out of a movie. There was tape that had everything taped off. There were cops with dogs and they were searching the garbage cans. They had cops on golf carts and they were just searching all around the crime scene. I just ran towards the cops and started yelling, shelley, shelley. Reporter they wouldnt let her in, of course. But they had questions. Well, they just wanted to know, like, if i knew her boyfriend and if i knew her roommate and who could have done Something Like this to her. Reporter meanwhile, youre flying down the highway as fast as you can go. Yeah. We were trying to get back. We were still trying to put it together in our minds what happened. Who took our little girl from us . And at that time, youre so torn up that thats you dont know what to do. Reporter what happeneded to this talented, modest, innocent young woman would be all too obvious very soon. But as for who did it, and why for the case to have the twist and turns that this one did was something that i wouldnt have dreamed in 100 years. And im seasoned. Ive seen a lot of things. Reporter no kidding. But not like this. Could the smallest of clues lead to the biggest of breaks . A little tiny sliver of the plastic about this long. When infatuation continues. A. Which is the only egg good enough for my family . A. Only egglands best. With more farmfresh taste, more vitamins, and 25 less saturated fat . Only egglands best. Better taste, better nutrition, better eggs. Discover. O i like your card, but im absolutely not paying an annual fee. Discover has no annual fees. Really . Yeah. We just dont believe in them. Oh nice. You would not believe how long ive been rehearsing that. No annual fee on any card. Only from discover. Dealing with your insurance shouldnt be more frustrating than the accident itself. Thats why esurance makes it simple. Just take some pics. [picture noises] go to sleep. Wake up. Grab a bite. Maybe some racquetball. And boom your moneys on the way so you can get back on the road fast. Well, not that fast. The editor had to make it fit in 30 seconds. Its pretty tricky actually trying to. And. Tagline. When insurance is simple, its surprisingly painless. She just never got into any trouble. At all. So thats what makes this so much harder. Because nothing like this should have ever happened to her. Especially to her. Especially to her reporter what was done to shelley nance, just 20 years old, was viciously ugly. That it was murder was all too obvious. The girl had been attacked as she lay probably asleep in bed. Her killer stabbed her again and again and again. Over 40 times. In the back. She was stabbed in her back. She was stabbed in her neck, behind her head. I mean this was brutal and this was savage. Reporter overkill, said detective paul ellzey. As will be clearly apparent, detective ellzey has deep roots in oldfashioned police work. Starting as a kid, then 36 years with the dallas p. D. Thats over now. Hes retired from the force. But he cannot get over the sight that greeted him in shelley nances bedroom. This was tragic, this was horrific. Reporter that sight sticks with you. Yes. Very much so. Reporter murder, as detective ellzey knew from long experience, takes something from the investigators, too. Makes them hard sometimes. But when he learned about the victim, about her decent family, her quiet modest life, her innocence, the murder of shelley nance hit him personally. I mean that was doin nothin wrong. She was not in the wrong place at the wrong time. She was not associating with somebody that she shouldnt have been associated with. The stars lined up just right that somebody, an animal, decided to take her life. Reporter sounds like it got to you, this one . Well, you know, ive got two daughters. And yeah, its its hard. Reporter shelley died here, in the falls, a large housing complex where the Art Institute arranged for some of its students to live. Seemed like a perfectly reasonable place, looked quite safe, when we stopped by to take some pictures one sunny afternoon. About you, i wouldnt let my daughter live there. Reporter really . Absolutely not. Reporter dallas, like any big american city, suffers from its share of crime. And the falls . You go there during the daytime, it looks very nice. But at nighttime, totally different story. Reporter innocent 20yearold girl out on the street in that neighborhood at night, youd worry about her . No way would i let my daughter walk that neighborhood at night, no way. Reporter the nances didnt know any better. Reporter little italy, after all, presents few of the issues a person can encounter in the middle of a place like dallas. Anyway, on that september day when detective ellzey arrived at the falls, he had no idea what sort of scene would confront him there. All he knew was that a female had been murdered. Im ready to go Different Directions and i have to make some assessments. When i walk in that door and i make a left hand turn and i see that girl there, then i can eliminate things relatively quickly. She still had her panties on, which generally reporter means no Sexual Assault. Exactly right. It it relieves the Sexual Assault part of it. She has a tshirt on. So im not thinkin that that its a rape. Im not thinkin that. And when i see the stab wounds in the back then i start thinkin personal. This is probably gonna be somebody that she knew. I checked the windows. I checked the door. You wanna look for forced entry. I didnt see evidence of that. Reporter so somebody she knew. And from the looks of it the wild, repeated, ferocious stabbing somebody consumed by an uncontrollable rage. But aside from all the blood, they found no useful fingerprints, and, eventually, no dna to help them either. Whoever did this had managed to erase any sign of who he or she was. Except there was one tiny bit of well, was it evidence, what was it . They found it under shelleys left wrist. A little bitty tiny sliver of plastic. About this long. And probably a quarter of an inch in width. Reporter hmm. Any idea what it was when you found it . It wasnt confirmed until after the completion of the autopsy of what the material actually was, that it was latex, a latex material. Reporter a a kind of material that that a pathologist would be rather familiar with doing his autopsies. It appeared to be a fragment of a disposable glove. Of course they tested it to be sure it did not come from the medical examiner or any of the officers at the crime scene. And it did not. Must have been left by the otherwise careful killer. But who would want to hurt her . And so horribly . The first person detective ellzey talked to was shelleys roommate, Ashley Olvera, whod found shelley dead in her own bed. Thats how ashley became possible suspect number one. She wasnt sexually assaulted, shelley. That was my initial opinion. It was later confirmed. Reporter yeah. Why couldnt a woman do this . Reporter sure. Its her roommate. Theres a lot of things happen between roommates that we dont know about. So it very well could have been. Reporter sure. What happened, if anything, between these roommates was something detective ellzey was determined to find out. Even if he had to get rough. Coming up right away, he would become convinced that something just wasnt right between the two girls. What else can you say . Its weird. Its not natural. Its not normal. Reporter when dateline continues. To be nobody but yourself in a world which is doing its best to make you everybody else. Means to fight the hardest battle, which any human being can fight and never stop. Does this sound dismal . It isnt. Its the most wonderful life on earth.

Back to date line. Welcome back. It was a senseless crime. Shelly nance who always steered clear of trouble, was stabbed to death in her own bedroom. Detectives believe the killer was somebody she knew. Possibly her roommate. After all, it was ashly who found her. Now, they were about to bring the young woman in for questioning. And would confront her with a potentially important piece of evidence. I kept thinking i was asleep, it was a really bad dream. And this wasnt really happening. I couldnt imagine anything like that ever happening. Definitely a shock. Reporter the first stage was denial. That shelley nance, their innocent wisp of a sister, had been murdered, was almost beyond comprehending. But maybe worse, quite possibly they werent going to know who did it. The first and most obvious mystery jumped right out at the experienced eyes that cased her bloody bedroom. Shelley had been dead a while. We could tell by lookin at her that she had not been there longer than 24 hours. Reporter but this was curious. Her roommate was in the apartment for much of that 24hour period, and claimed she saw and heard nothing amiss. Like shelley, roommate Ashley Olvera was also 20 years old and from a tiny town taft, texas not far from corpus christi, on the other side of the st
