Good night, america im nick cannon from hollywood. Good night, america. Lywood. Good night, america. Watching us, girls, work at the palms. We didnt know if any of us were next. The predator theory got a boost that second day when, on a walking path near shaunas house, someone found bits from her purse i. D. , makeup kit, personal things. What crosses your mind when you realize its somebody walking away from the scene, discarding things . A stalker . Absolutely. A predator. Sexual predator. They spread out, got the rest of homicide involved. Days off were cancelled. Everybody out. They looked everywhere. There was considerable pressure. Pressure from media. Pressure from our administration. Everybody wants this thing solved and put away quickly. And then quite suddenly, a break. A tipster on the crimestoppers line with a story to tell. He had some information that he thought was connected to our murder. A wild goose chase . Maybe. And maybe not. Coming up, the tipster mentioned a detail about the crime, one that gets everyones attention. No one knew that but the two of us. This guy brings it up. Exactly. When dateline continues. Good job. Yay. Good singing. Its a terrible thing to bury a young mother in the prime of her life. Especially in the shadow of murder. Big sister paula had felt somehow frozen in a terrible dream that refused to end or make sense ever since her mother called with the news about shauna. Whats it like to hear Something Like that . I dont know that you can describe it. You know, i mean, your heart just drops to your stomach. Paula and shaunas family and friends gathered to mourn and remember how much they cared about her. The funeral itself was standing room only. It was a beautiful tribute to shauna. Georges big sister, maria i could see george was heartfelt and did what he could to express himself at a terrible time. It was all about showing that shauna was loved and cared for. Meanwhile, las vegas homicide detectives worked diligently to identify and track down whoever killed her. Do we have a predator . Did she come home and they were burglarizing the house . Is there an enemy somewhere that she made that we need to find . And then, they got lucky. A man who called himself big will pennix called the crimestoppers hotline. Big will had a story to tell. He had spent time in prison. And he worked as a maintenance man. But he found satisfaction in helping others coming out of prison and helping them find the right path. One such man, said big will, was a homeless handyman who lived out in the desert. Went by the name greyhound. He did a lot of drugs. Drank a lot of alcohol. And was volatile. According to big will, this greyhound told a lot of tall tales, but will called police this time because greyhound bragged about killing someone a woman. And said he used a hammer to do it. And we had just come from autopsy that morning. Marks that were seen on shaunas body, we thought that it was possibly a hammer. So no one knew that but the two of us. But this guy brings it up. Thats exactly. A homeless, drug addicted excon with a volatile temper, said big will. Certainly seemed to fit the profile of the potential predator detectives were looking for. But big will told them, finding greyhound might not be so easy. He told us that greyhound walks everywhere. He lives out in the desert. But big will wanted to help, he said, so he agreed to take them to some of the places he thought greyhound liked to hang out. And, what do you know . They ran into him in the parking lot of a gas station. Detective long approached him. Sweet as pie, greyhound was. Said hed be perfectly willing to go to the station and have a chat. His real name was noel stevens. What did he tell you . He knows shauna. He knew where they lived. That he did yard work and handyman work for george and everybody else in the neighborhood. So someone shauna knew, someone george, the dogooder, had tried to help. A thing not out of character for george. But greyhound, or, noel, was adamant that he had nothing to do with shaunas murder. Then he agreed to show the detectives his campsite out in the desert. What did you find . Swimsuit bottoms that in our search of shaunas house appeared to me that matched the top that i had seen in her bedroom. There was also an extra small black dress, which, you know, shauna was very tiny. So greyhound was the burglar poking around shaunas personal things. And in fact, her friend recalled shauna had grown uncomfortable with this particular charity case whod been doing work around the house. She didnt want noel in the house anymore. And she said, you know, you better get out of this house or im calling the police on you. So was he the killer . Out at the campsite, detectives did not find any evidence linking him to the murder. So, they kept looking. One of the other things big will told us was that noel had a campsite number one and a campsite number two. A second campsite out there somewhere. But where . And what, if anything, was hidden there . Coming up under the bush he saw a pair of jeans that appeared to have blood on them. A dark discovery seems to provide answers, so why are detectives about to confront a series of new and troubling questions . Its not on any sightseeing itinerary, not this way, but this, too, is las vegas. Rugged desert terrain that is a kind of refuge or hiding place for the desperate and troubled. Believe it or not, that whole area has Homeless People that are up there. This is where greyhound took them. This is where he lived, he said. But out there somewhere, they were convinced there must be a second campsite with possible evidence about the killing of Shauna Tiaffay. So detective miller went up with the Police Air Unit to have a look around. Those two pilots decided that they were going to fly that whole area for us, and they actually located the second campsite. And we entered and we found a citation in the name of noel stevens, so we were in the right place. So they spread out, kept looking. And pretty soon, one of them called out. About 175 feet from the tent, he found a bush. And under the bush he saw a pair of rolled up denim jeans that appeared to him to have blood on them. We put those in for immediate dna testing. How did that come back . It was Shauna Tiaffays blood, and the pants were worn by noel stevens. Thats kinda your story there, huh . Thats kind of our story there. Proof the homeless handyman george and shauna tried to help was a murderer. But could the story be that simple, really . Listen to shaunas sister, paula, for example, and things start to sound a bit more complex. Well, i just think that he always loved himself more than he loved anyone else. And it was all about him and what he wanted. That was george she was talking about. The selfless firefighter had another side, said paula. The verbal abuse, the intimidation, the control. I mean, george was always a controlling guy. Hold the camera in your hand. Push it away from you. According to paula, george had become ever more controlling, and judgmental, especially about shaunas spending habits. First time at the beach. Only got worse when shauna told george the marriage was over. He said, you know, if you dont come back to me and we cant sort this out, youre going to lose custody of your daughter. And that was that was his threat. Her number one fear. Oh, absolutely. He used their daughter as a way to manipulate shauna, time and time again. Shauna had been letting her work mates read the Text Messages george sent as things got worse in the marriage. One text, it would be nice, you know, short and sweet. Like, i love you. Ive been thinking about you all day, we need to work things out. And then, you know, we would be working. She wouldnt be able to text him back right away, and ten minutes later, hes blowing up her phone cussing her out, calling her names. Shaunas supporters remembered her funeral quite differently than georges people did. He had no emotion. No emotion at all. He did a eulogy, talking about how much money shauna liked to spend, and that there was one time she was at the gas station and accidentally left the pump in the car. In the eulogy . In the eulogy. Paula watched george and his daughter at the cemetery and fumed. They hadnt even lowered her in the ground yet, and he said, come on, and took her hand, its time to go. And i watched him walk off with my little niece, you know, 8 yearsold, just lost her mom, and i watched him walk off with her. And i thought, you know, this is exactly what he wanted. He wanted all the control over my niece. Paula told the police her suspicions, even before they began chasing down leads on greyhound. So even though they had their killer, the idea that george was involved somehow was already in the back of their minds. On the other hand, georges family was just as eager to assure the police that those attacks on georges character from shaunas side were complete nonsense. I never saw shauna act cowed or afraid of my brother. She had an equal footing in the way they interacted with one another. So thats thats why i still cant believe the it the insinuation, the allegations that that he was abusive, or even controlling. Georges friend, aaron solano, couldnt agree more. No matter where he finds himself, what challenging situation he finds himself in, hes always been consistently kind, consistently caring. So which george was the real one . The detectives decided to pay george a visit at his house, though they didnt tell him what theyd heard about him. The good or the bad. Mr. Can i call you george . Yeah, call me george. Thank you. George said, sure, he knew greyhound. But said hed never heard him called noel stevens before. You knew him as Something Else . I knew him as neal smith. George told detectives how he and shauna had befriended this neal smith. Tried to help him get back on his feet. Me and the wife kinda looked at him like our Little Charity case because he was a nice guy and hes down on his luck. By now, the detectives knew greyhound was an addict and a big drinker. So they asked george. Was he a drug user . Nothing. Okay. Alcohol . Yes. He would drink alcohol, but not a lot. Just a beer or two. Just a beer or two every now and then . Yeah. That raised the antenna a bit. In his interview with detectives, greyhound said he and george were great friends, worked out together, drank together a lot. But then, listen to this. As george kept talking, the man he said he knew as neal became noel. She said, can noel help us out with this . If it was something i wasnt good at, well maybe noel is good at it. Because noel seemed to be good at everything i wasnt good at. Remember, george said hed never heard the name noel stevens before. Knew greyhound only as neal smith. So, was it an honest little slip or was george hiding something . Is it possible he was confused about the name, that it, you know, greyhound used several different names . When you get nervous, youre gonna revert back to whatever is natural. And he reverted back to noel. He just got done telling us, ive known this man for years as neal, and then, noel helped me move. So i thats a tell. But why would george admit to knowing greyhound and then lie about the name . The detectives left george at home and made a plan they hoped would shake out the truth. We decided to amp up the pressure. Coming up, a bold calculation by detectives was about to trigger a stunning chain reaction. He was driving extremely fast and forcing vehicles off the road and then plowed straight into a cement barrier. The officer following said he just committed suicide. When dateline continues. Hush my darling. Dont fear my darling. The lion sleeps tonight. [snoring. ] hush my darling. [snoring. ] dont fear my darling. The lion sleeps tonight. [snoring. ] take the roar out of snore.
