nelson villavicenzio and his wife were just outside while the murder occurred. had they stopped in to say hello to sarah, they, too, might have been victims. in october of 2006, kosoul was convicted of capital murder and sentenced to death. people will kill for the most trivial of reasons. reasons that no rational person would ever imagine. what the science did in this case is it made that defense attorney get up in his opening statement and say, my client was guilty and this was a robbery gone bad. he would not have said that if we hadn t had the physical evidence that we had in this case. this case turned out to be the perfect marriage of good police work, excellent science, and prosecutorial expertise. it was the perfect blend of all
walker arrive for work across the street. i yelled at my wife, come and check this out. there s a beautiful blonde coming out of this sports car and she s going to the model. my wife said oh, that is sarah. and i said, oh, sarah is looking very good. she said, well, yeah. when nelson and his wife realized that their appointment was a no-show, they left, and saw the white mustang parked next to sarah walker s car. nelson said they considered stopping by to say hello to sarah. said well, are we going to go visit with sarah? and my wife said no, we re hungry, so we left. they left at approximately 1:00 p.m.
and she tried to call the hotel he said he was at to find out what time he was coming, and he was not in the room that he said he was in. in fact, no chan lee was registered at the hotel, but she still agreed to meet him. remember when you re in the real estate business, you re in the business of making a commission. so you re going to accept all comers. the realtor did take precautions. my wife asked me if i wanted to come along, and i said yes, and i did it for my reasons. when they arrived, an asian male drove up in a white mustang. he had a t-shirt, no sleeves, jeans, sneakers, very athletic. and i asked him, excuse me, sir, is your name chan lee, and he looked up in the sky. did not make any eye contact with me and sort of gave me a vague loose saying like no, but he didn t express anything. the man walked quickly to his car and drove away. while nelson and his wife waited in the townhome, they saw sarah
if i exchange one e-mail with a random stranger or if i just write something like no, thanks, i m not interested. you have a suspect right there. if you return 30 or 40 no thank yous in a week, and trust me, women get inundated with that many requests, well, you ve got 40 suspects. investigators interviewed all the men sarah spoke to from the site. each provided a dna sample and all were eliminated. by this time, several weeks had passed. and the trail of sarah s killer was turning cold. then unexpectedly, nelson villavicenzio, the husband of another realtor, came forward with some new information. he said on the morning of sarah s murder, his wife got a call from a man who identified himself as chan lee. he wanted to see the model home located across the street from the home where sarah was killed. she felt a little suspicious about him and wondered if he was legitimate.
sarah s body was discovered 20 minutes later. the possibility of we had visited sarah and found myself and ourselves in the middle of it, of something terrible, will always be on my mind. i consider nelson s wife to be very lucky. i think there s a high likelihood that she would have been the victim that day had she not brought her husband along with her to that subdivision. police now had a possible eye witness. but would it be enough?
