delight and sin in an unaccustomed shade of pale. it was september 29, 2012. at precisely 3:00 in the morning, in a back room of the palms casino, the cocktail waitress named shauna tiaffay inserted her time card in the staffing machine and set out to break a little rule. shauna had parked her car in the back lot, a practice discouraged because surveillance cameras were unable to track her all the way to her car. still easier this way. quicker. and after all, would a stalker really be waiting for her here, under a full moon? >> is t wasolutely horrible. and we felt so helpless. >> it's every woman's worst nightmar >> we didn't know if any of us were next. >> it never occurred to shauna to become a cocktail waitress when she ved to vegas as a 20-something back in the mid-90s. what shewas to be closer to family, meaning big sister paula.

>> she originally just thought, "oh, t i don't even drink." >> but in a casino town, a cocktail waitress could make good money. so now, at 46, she was a tera ndhe wld lau. sht rself a lot.d laugh at hers and, you know, she'd say, "well, i stl don't , yoow, what these cocktails are. you know, i -- i just order 'em and they give them to me and i go take them to the -- the people." >> but she w good at it. everody could see that. >>ll the customers loved shauna so much. >> why? >> she was a sweet person. >> beautiful. >> she made close friends. a work family, really, including kelly chapman and stephanie vargas. >> i remember there was one time, i was in the -- i was at one of bars and i saw her walk by. every single head turned on that bar watching her walk by. ani rember thiing, i'm like, "why don't i look like her?" because men, women, they -- they just loved her. no onlodquite the way he did.

a handsome b scout of a firefighter named gege tiaffay. george was the genuine article. an a american good guy. he'd yeefr overcome early obstacles to become a top notch student in high school, a star athlete. this is his sisteraria mcgrew. >> a valedictorian and on the football team. i -- >> yeah, you'd think -- >> --he'd just be a jerk, right? >> yeah. >> just kind of a jock, mean-spirited sort of, who knows, stereotypical. >> but it was quite the contrary, said maria. >> he was always the calming force amongst mily and friends. you know, he was the gentle speaker. he had this outlook in life where, "i wanna go out and make the world a better place. with my life." >> so george did. he earned a prestigious appointment to west point, and after graduation bece a combat engineer, served as a nation builder in panama. his childhood friend, aaron solano, went down for a

visit. >> the stories he told me about the missions that he accomplished. building schools, clinics, roadways and bridges, really had an impact on his life. he finally felt like, "hey, i'm getting to do something." >> when george left the military with the rank of captain, he took a corporate engineering job, but soon realized that life in an office building wasn't for him. he wanted to work for real people, which is why george put aside that fancy degree of his and went to vegas to train as a firefighter/emt. >> focusing on himself was not how he wanted to live his life. he wanted to serve. that was a favorite word of his, to serve. >> so while shauna served drinks at the palms, george served as a fire fighter and found time to volunteer, do what he could for the down on their luck souls who live on the fringes of so much glitz. in 2004, they had a baby. >> there's daddy and mama. >> she loved it.

her daughter was the most important thing to her in this world, and everything she did revolved around her daughter. >> and then, two years later, a marriage in hawaii. just the three of them. back in vegas it was a busy, if complicated life what with george's 24 hour shifts, and shauna's night times at the casino. and then it was september 29th, 3:00 a.m. she walked the empty lot to her car, started it, pointed away from the strip. and under that full moon headed home. no idea what was waiting for her. it was 9:00 a.m. when george arrived with their daughter. she'd spent the night at grandma's, he at the firehouse at work. but why was the garage door open? and what was that inside? george had grown accustomed to trauma and death.

part of what made it so incomprehensible was where it happened. shauna tiaffay lived in a good, safe, neighborhood. part of town where vegas does not party, a part of town where the people who work the casinos raise their families and live ordinary quiet lives. but, this is where they found her. george and the eig-year-old daughter. inside her own house. not so safe after all. eport a break in and a murder. >> george would have known even if he hadn't been an emt. >> what's going on there? >> she'd been dead for hours. >> my wife. my wife is on the floor, bloody, stiff, not moving. >> we got a call in the morning. >> detective dan long has been in homicide a long time, and god knows, vegas has kept him busy.

him and his partner terri ment personnel everywhere. >> it was all too obvious. shauna had been attacked, probably as she walked into her house, had been beaten with something blunt and hard. >> and there was things done with the body that made us think that there was possible sexual assault of some type and there was posing of the body. >> some kind of predator at work here? a predator who escaped with a good hunk of cash from the looks of it -- suna's purse was missing. >> cash and casino chips. they get tipped withasino chips quite a bit. they're known to make $300, $400, $500 a night. they make a lot of money. especially if they're good. and we d send deblgts detectives over to the palms. they talked to them. they said shauna is one of the best employees they had.

>> but somethi happed after she left the palms. so what? >> shauna was very beautiful. is it someone that saw her at work and followed her home? >> of course as the husband, george would havto be considered a possible suspect, too. so detectives pulled him aside, interviewed him right on the spot. >> george, do you understand the statement's being recorded? >> i understand. >> and you understand we want to talk to you about what happened this morning? >> yes, sir. >> george told detectives that when he saw the garage door open, he had tir dghtehang back while he went inside. >> i saw shauna's feet. just laying there frozen looking. and, in my job, i know what that means. >> ok are you a paramedic? >> i'm an emti firefighter. >> their daughter, ank god, didn't see anything, said george. he rusheher out to the street. >> i dt know if there was somebody there. i wanted to get out of there with my daughter.

>> he d takethe littirl to shauna's place, he said, because it was shna's turn. >> we are currently separated, but planned on moving back in gether because we started to get along again. >> and meanwhile, they had this shauna worked 7:00 p.m. to 3:00 a.m. at the casino. george, as a firefighter, worked long shifts and got lots of ys off. their daughter shuttled back and forth between them and when they were both at work, the girl spent nights with george's mother. what shift did you work yesterday? >> a 24-hour shift. >> so he was at work when shauna was killed. course, they did some checking, just to be sure. >> you know, if he was there on every run. you know, if he had left for any reason. >> but he was on every run. did not leave work. at all. so, not the husband this time. >> he had nothing to do with the attack of shauna. >> but george did offer a possible lead. >> the garage door was open,

which is unusual. so we were worried because my wife's house got broken into a week or two ago. >> the thief in that earlier burglary, it appeared, used shauna's bathroom to take a shower and left with several pairs of shauna's panties and some jewelry. he left behind a pair of boxer shorts, size small. back then shauna immediately suspected some neighborhood teens, said george. >> so she had discussed it with several people, including george, and decided that it may be that she left something unlocked. and it could be maybe some kids that live in the neighborhood. >> so is that who killed her? looking around the crime scene, the detectives realized that shauna's killer or killers had been into her booze, had taken not just her purse but, like in

that earlier burglary, her underwear so they set about checking out every one of the neighborhood boys and -- they had solid alibis, all of them. >> they were not involved in the break in. theyere not involved in shauna's death. now things get even more scary, because we don't know what we have. >> once that word got out, it could very quickly spread the terrorround. like it already had among shauna's co-workers. >> we didn't know if there was some psycho watching, you know, watching us, girls, work at the palms. we didn't know if any of us were next. >> the predatotheory got a boost that second day when on a walking path near shauna's house someone found bits from her purse -- i.d., makeup kit, personal things. >> what crosses your mind when you realize it's somebody walking away from the scene, discarding things? sexual predator. they spread out

the rest of homicide involved. days off were cancelled. everybody out. they looked everywhere. there was considerable pressure. essure from media. administration. everybody wants this thing solved and put away quickly. >> and thequite suddenly, a break. a tipster the crimestper's 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 everyone's attention. >> no one knew that but the two of us. >> this guy brings it up. >> exactly. >> when "dateline" continues. mmmm... when you add liquid gold velveeta to rotel tomatoes and zesty ie

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 d 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. >> reporter: swuchb 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 killinsomeone -- 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 shauna's body, we thought that it was possibly a hammer. so no one kn that but the two of us. >> but this guy brings it up. that's -- >> exactly. >> a homeless, drug addicted ex-con with a volatile temper, said big will. certainly seemed to fit the profile of the penti 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.>> b he said, so he agreed to take them to some of the places he thought greyhound liked to hang t. 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 he'd be perfectly willing

chato to the station and have a his realame was noeltevens what did he ll you? >> he knows shauna. he knew where they lived. that he did yard work and handym work for george and everybody else in the neighborhood. >> so someone shauna knew, somee george, the do-gder, 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 shauna's murder. then he reed to show the detectives his campsite out in the desert. what did you find? >> swimsuit bottoms that in our search of shauna's house appeared to me that matched the top at 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 shauna's personal

things. and in fact, her friend recalled shauna had grown uncomfortable with this particular charity case who'd been doing work around the house. >> didn'want n theoein house anymore. and she said, you know, you better get out of this house or i'm calling the police on you. >> so was he the kilr? 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 coront a

i mean, george was always a controlling guy. >> hold the came >> according to paula, george had become ever more controlling, and judgmental, im. >> only got worse when shauna told george the marria was over. >> he said, you know, "if you don't come back to me and we can't sort this out, you're going to lose custody of your daughter." and that was -- >> that was s threat. >> -- her number one fear. , absolutely. and she -- he used their daughter as a way ñ manipulate shauna, time and time again. >> shauna had been letting her work mat read the text messages george sent as things got worse in the marriage. >> one text, it would be nice, u know, and sweet. like, "i love you. i've been thinking aboutou all day," "we need to work things " and then, you know, we would be working. she wouldn't be able to text him back right away and ten minutes later, he's blowing up her phone cuher t, cling her

killer, the idea that george was involved somehow was already in the back otheir minds. on the other hand, grg family was just as eager to assurehe police at those attacks on george's character from shauna's side were complete nonsense >> i never saw st cowed or afraid of my brother. she had an equal footing in the way they interacted with one her. so that's -- the -- it -- the insinuation the allegations that -- that he was abusive, or even controlling. >> george's friend, aaron solano couldn't agree more. >> no matter where he finds himself, what challenging situation he finds himself in, he's always been consistently kind, consistently caring. one? the detectives decided to pay george a visit at his house,

though they didn't tell him what they'd heard about him. >> mr. -- can i call you george. >> george id, sure, he knew greyhound. but said he'd never heard him called noel stevens before. >> you knew him as something else? >> i knew m as neal smith. >> george ld detectives w he and auna had befriended this neal smith. tried to help him get back on hifeet. >> me and the wife kinda looked at him like uh, ke our little charity case because he was a nice guy and he's 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? >>es. 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 ther 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 wasn't good at, well maybe noel is good at it. because noel seemed to be good at everything i wasn't good at. >> remember, grge said he'd never heard e name noel stevens before. knew greyhound only as al 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 you're gonna vert back to whatever is natural. and he reverted back to noel. he just got done telling him, "i've known this man for years as neal," and then, "noel helped me move." so i -- that's a tell. >> but why would jorng george admit to knowing greyhound and then lie about the name? the detectives left george at
