ron shaw's murder was a major news story in louisiana and the entire gulf coast region. >> it was huge. it was characterized as a well-organized home invasion of people who police believe laid in wait for the shaw family. >> the victim was portrayed as a very wealthy business executive. and then to have him killed in

front of his wife certainly hit a nerve with society in general. >> the shaws' home was only a few months old. not all of the landscaping had been completed. and this produced the first piece of evidence. >> it's a new construction. there was builder's sand in the back of the house. so, as the suspects stepped in that sand in the back of the house and went through the house, they left real nice shoe impressions down the hallway. >> the outside print was preserved with a substance called denstone. >> kind of like pancake batter. then you're able to lift those impressions and bring them back to the crime laboratory. >> inside though home, investigators lit the hardwood floors from various angles and saw two more sets of shoe impressions. criminalists lifted the prints

with gelatin strips. >> you roll the gelatin with the black side down onto your questioned shoe impression. and when you peel it off, the adhesive in the gelatin adheres to the dust particles on the floor. >> with some research, investigators identified the prints outside as a pair of size 10 nike air jordans. the perpetrators inside also wore nike shoes. one wore the air medal force model, the other the shocks trainers. when police interviewed the neighbors, several of them said they saw a burgundy-colored car parked a short distance away from the shaws' home. >> the vehicle was occupied by black males. either they observed these black males within the vehicle or standing outside the vehicle, but it was parked in front of a vacant lot in this particular neighborhood, so it did stand out.

>> and about a mile from the crime scene, search dogs found a potentially crucial piece of evidence. >> while they were walking around in the roadway, they discovered a red ski mask with blue outlines on it next to the roadway, which was in direct line of sight to the rear of the victim's property. >> this ski mask, red with dark trimming around the eyes, was similar to the one described by rosana shaw. at ron's autopsy, the medical examiner confirmed that ron shaw was shot three times with a .38-caliber weapon. >> there were two torso shots. one of those torso shots, the bullet remained. the other torso shot, the bullet went all the way through his body. >> in the yard, investigators found the projectile that passed through shaw's body. this, along with the two bullets found inside shaw's body were sent to the forensics lab.

under a microscope, firearms expert chris henderson discovered that the lands and grooves on two bullets were the same. the third bullet was different. >> we determined that we had two different shooters, based on the class characteristics of the bullets. >> in their search for potential suspects, police had to consider whether rosana shaw had anything to do with her husband's murder. ron's grown son from his first marriage certainly thought so. >> he had kiss trust for her. he wondered what her motivation was for marrying his father. had she married for money? >> and there were others who had a potential motive. a background check revealed ron had shifted funds from one oil drilling research project to another. one was successful, the other wasn't, which created substantial losses for

investors. >> there were a couple of them that had actually lost hundreds of thousands of dollars. it didn't surprise them at all that the victim had met such a violent death, because they felt that his business practices were dubious and unethical. >> with so many potential avenues to explore, investigators focused first on who knew that the shaws had a safe? >> the people that knew about the safe was the safe company, my family, ronnie's family, people at the office, the architect, the construction workers, friends. there was a lot of people that could have known about the safe. >> the general contractor who built the shaws' home fully cooperated with authorities. >> ernest touchet revealed the names of several disgruntled employees that he felt might play a role. and later added that he also had

two grandsons that had worked on the home and that had also recently had several run-ins with the law. >> but investigators dismissed that idea. the perpetrators were black, yet, ernest touchet, and presumably his grandsons, were white, and ron shaw knew these boys personally. >> ernest touchet came to my husband and asked to hire his two grandchildren to keep them out of trouble. you know, they needed to do something. so, my husband says sure. my husband really appreciated the grandfather, ernest touchet, so, he said, of course, bring your two grandchildren and i'll hire them. >> police didn't believe the touchet boys would repay ron shaw's kindness in this way, or would they?

initially, police thought little of it, since the perpetrators were black and ernest touchet was white, until they looked at the mugshots of his grandsons. >> shannon touchet was a black male and was a product of an interracial marriage that his mother had had during her earlier years. >> 17-year-old shannon touchet had worked on ron shaw's home and would have known about the safe hidden in the master bathroom closet. investigators went to shannon's home. he wasn't there, but his mother was, and she was very helpful. >> she reported to us that she had found some bullets and a black bag, a black bag that she recalled had at one time also contained ski masks and drugs. >> police found the bag in shannon's bedroom.

the drugs and ski masks were gone, but they did find 13 unfired .38-caliber bullets. investigators wondered whether these bullets matched the ones that killed ron shaw. firearms expert chris henderson examined the knurls on the fatal bullets. knurls are the ridge-like protrusions that hold the lubrication needed to fire them. henderson then compared those knurls with the knurls on the bullets in shannon touchet's bag. >> we had the same number of knurls, same width, and those knurls looked kind of like railroad tracks going around the outer surface of that bullet. all the physical characteristics, everything that we could physically see and measure were indistinguishable from one another. we could not tell the difference between one and the other. >> police brought shannon touchet in for questioning. he insisted he knew nothing about ron shaw's murder. he said he was with his

girlfriend that night. >> she did verify his alibi and stated that shannon touchet was, in fact, with her in lake charles. >> but looking at shannon's shoes, investigators noticed he was wearing nike air jordan basketball shoes, similar to the shoe impressions at the crime scene. scientists took casts of shannon's shoes and compared them to the cast from the impression in the sand outside ron shaw's home. >> we concluded that the shoe impressions at the crime scene were basically indistinguishable from those of shannon touchet's shoes. they had the same wear, the same physical characteristics, they were nike air jordans, same size. >> shannon's own mother disputed his alibi. she told investigators that shannon was out with two friends on the night of the murder, reggie basile and ronald benson, and they were driving a burgundy

car, similar to the one witnesses saw near the murder scene. when questioned, both reggie basile and ronald benson denied any involvement in the robbery and murder. police obtained a search warrant and confiscated all of the shoes belonging to the two men, but none matched the shoe impressions found inside shaw's home. so investigators decided to look for genetic material inside the red ski mask that had been discarded after the murder. the forensic scientist turned the mask inside out and swabbed around the mouth area, hoping to pick up cells from saliva. >> using the entire surface area of the swab to collect as much of the potential cellular material that's there. >> using a dna test called str, or short tandem repeats,

scientists found dna from three different individuals inside the mask, but investigators needed to know who was wearing the mask before it was discarded. to find out, they analyzed the swab from the ski mask to determine who left most of the saliva behind, and the results of this test were clear. >> in this case, the major contributor of dna matched that of ronald benson. >> the red ski mask was very important because it corroborated the story that we were able to receive from mrs. shaw. mrs. shaw indicated that the person with the red mask was the most aggressive in the robbery. >> the identity of the other two dna profiles in the mask was inconclusive. the ski mask implicated ronald benson. the shoe impression outside the

shaws' home implicated shannon touchet. but there was no forensic evidence linking reggie basile to the crime. >> as an investigator, that's a little hard to swallow, you know. that's a little hard to leave in the end of the day with, knowing that there's nothing else you can do, and you feel fairly certain of who's responsible for doing it. >> investigators hoped that would change. if yand you're talking toevere rheumyour rheumatologiste me, about a biologic... this is humira. this is humira helping to relieve my pain and protect my joints from further damage. this is humira giving me new perspective. doctors have been prescribing humira for ten years. humira works for many adults. it targets and helps to block a specific source of inflammation that contributes to ra symptoms. humira can lower your ability to fight infections, including tuberculosis. serious, sometimes fatal infections and cancers,
