sean's bathroom to take a shower, and left with several pairs of shawn's panties and jewelry. he left behind a pair of boxer shorts that were small. back, then shawn a mediately suspected some neighborhood teens, said george. >> so she had discussed it with several people, including george, and decided that maybe, she left something unlocked and it could be some kids that live in the neighborhood. >> so, is that who killed her? looking around the crime scene, the detectives realize that china'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 said about checking every one of the neighborhood boys and they had solid alibis, all of them. >> they were not involved in the break-in, they were not involved in sean's death. now things get even more scary.

because we don't know -- >> what's that word got out, it can very quickly spread the terror around, like it already had among shauna's coworkers. >> we did not know if there was a cycle watching us girls working at the palms, and we don't know if any of us were next. >> the predatory -- got a boost on that second, i went on a walking path near shawn's house, someone found bits of her purse, i.d., makeup kit, personal things. >> what crosses your mind when you realize it's someone walking away from the scene discarding things? >> a stop. or, absolutely, a predator, sexual predator. >> spread, out that got the rest of homicide involved, days off were canceled. everybody, out they looked everywhere. >> there was considerable pressure. pressure from media, pressure from our administration. everyone wants this thing solved and put away quickly. >> and then, quite suddenly, a

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. >> if we have a predator, and she came home, and they were both rising 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 panics called the crime stoppers. big will have 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, drink

a lot of alcohol, and was volatile. >> according to big will, this greyhound total lot of tall tales. but will called police this time because greyhound bragged about killing someone, a woman. and said that he used a hammer to do it. >> and we had just come from autopsy that morning, mark said we were seeing on her body, we thought it was possibly hammer. so no one knew a but the two of us. >> when it guy brings it up it's -- >> exactly. >> a homeless, drug addicted ex-con with a volatile temper, said big will. certainly seem to fit the profile of a potential predator, detectives were looking for. >> he told us that greyhound walks everywhere, he lives out in the desert. >> big will wanted to help, he, said so he agreed to take them to some of the places we thought greyhound like to hang out. and what do you know? they ran into him in the

personal things, and in fact, her friends had recalled that she had grown uncomfortable with this charity case we did work around the house. >> she did mondale in the house anymore and she said, you better get out of this house or i'm calling the police on you. >> so was he the killer? out of the campsite, detectives did not find any evidence linking him to the murder. so, they kept looking. >> one of the other things that big will told us was that noel stevens had a campsite number two, and a campsite number. to >> a second campsite, out there, somewhere. but where? and what, if anything, was hidden there? >> coming up. >> in the bush, he saw a pair of jeans. it appeared to have blood on them. >> when dateline continues. appeared to have blood your by to unblock your gut.
