world. no longer was cutting a disk in two enough. >> the implications of our technique was for $131 and not a lot of brain cells we can retrieve that data. and now everybody has to change their protocol on how to safeguard classified information. at times a perpetrator's dna is the only clue at a murder scene. this case made forensic history when scientists saw in these genes, literally, the killers physical description. in the 1600s baton rouge and louisiana got its name from french settlers and meant red stick. to this day, baton rouge is one of the most racially diverse cities in the country. pam kinamore new the town's history well by birth and by profession. pam operated an antiques store. >> pam loved life. every day she couldn't wait to do all the things that she

wanted to do. she was fun. she was exuberant. she was enthused. she was intelligent. >> shortly before midnight on a friday in july, 2002, pam's husband byron called police to report his wife missing. he said when he got home the front door was wide open. his wife's keys were there. but pam was gone. strangely, the bathtub was full of water. >> it looked like she had been taking a bath and also there was some blood on a rug under the bed in the bedroom. that hadn't been there before.

forensic testing revealed the blood on the carpet was pam's. it appeared that she left her keys in the door inadvertently and an intruder walked in while pam was in the bathtub. the couple's son was sleeping overnight at a friend's house and couldn't shed any light on what happened. investigators also had to consider whether pam had simply run off. but her mother refused even to consider that possibility. >> i told them, i said your next thought is she might have had a boyfriend. i said i give you my word of honor if she had a boyfriend, i would have known and that would be the first name i would give you. pam never looked at another man. byron was herb sweetheart. >> pam's family posted missing

posters and billboards all over the city and offered a $75,000 reward for information as to her whereabouts. for four days the search continued. pam's body was discovered in the marsh land under the whiskey bay bridge 60 miles from her home. >> it is amazing it was found. it was found by surveyors. she had been dumped at whiskey bay. the coroner's office took her into custody. >> the medical examiner discovered pam had been stabbed to death and had also been sexually assaulted. >> pam was a beautiful young woman. and she had a lot of admirers and i thought maybe somebody just had a crush on her and took

her off. i guess we wanted hope. i never dreamed that she was murdered. do you know what it's like to know you'll never have any more memories that all those happy times are gone forever? so that's what it's like lose your child. >> the medical examiner determined that pam had been killed on the night she disappeared. pam's husband, byron had an alibi and it was corroborated by others so he wasn't considered a suspect. but police got a tip from a potential eyewitness. he thought he saw pam slumped forward in a white pickup truck on the night she went missing just a mile from where the body was discovered. >> this is a desolate piece of interstate very dark. not many vehicles would get off at this exit ramp. it leads to nowhere, where her body was found. >> the witness said the driver was a young, white male. >> police began to look for a white male in a white truck. >> unfortunately there were

35,000 white pickup trucks registered in the baton rouge area. . at pam kinamore's autopsy, and tipped off the house which used all that energy to stay warm through the storm. chipmunk: there's a bad storm comin! narrator: the internet of everything is changing how energy works. is your network ready?"

at pam kinamore's autopsy, pathologists found biological evidence that she had been sexually assaulted and it also contained the dna profile of her killer. naturally investigators wanted to know if this perpetrator had been apprehended before. >> we had already taken his dna profile and searched it into the fbi codis data bait which is a national database of offenders as well as evidence from other cases. and we knew then at that point he had not been linked to any other crimes. >> but this dna evidence did tell police something important, the same man who killed pam kinamore killed two other women several months earlier. >> i had never had experience with a serial killer other than seeing it in tv shows.

so all of a sudden this was something that batten rouge hadn't dealt with before. >> two months earlier, charlotte murray pace a graduate student at louisiana state university had been sexually assaulted and killed in her apartment. >> she was stabbed 81 times. her throat was cut. she was missing part of her ear. it was very violent, horrible attack. >> all the people, all the women in the world, he picked murray. why? i'd give anything to know why. and i don't know if you can know why because i wonder if he could articulate why if he knows why himself? >> like pam kinamore's case, there were no signs of forced entry. >> this person was absolutely vicious. >> also in that same neighborhood gina green, a nurse, was sexually assaulted and murdered in her home.

in all three cases the common thread was the telephone. either the killer took the victim's telephone or used the cords to restrain his victim. this led to speculation the killer asked his victims for assistance. >> everything he touched he took with him. those were his trophies. it at no time take much to wipe down the doorknob. he knew everything he touched. >> when residents of baton rouge learned a serial killer was on the loose they took all precautions. at night the streets were all but empty. but it wasn't enough. several months later, the killer struck again. 23-year-old trineisha dene

colomb never returned home from visiting her mother's grave. her body was discovered 26 miles away from the cemetery. she was sexually assaulted and beaten to death. a witness reported seeing a white male in a white pickup truck near the cemetery just like pam kinamore's case. and the killer wasn't through. the body of 26-year-old carrie yoder, a doctoral student at lsu was found near the whiskey bay bridge not far from where pam kinamore's body was discovered. dna tests confirmed the same man sexually assaulted and presumably killed all five women. >> he's very intelligent. i think he was doing a lot of surveillance stalking his

movements. methods and movement. he will be tough to catch. >> desperate for a lead police called the fbi in washington, d.c. and asked for a criminal investigative analysis of the crimes. >> we thought this was someone who followed women and watched women from afar and when he interacted with women it would be shortly into that interact before they felt uncomfortable with him. >> the fbi predicted the killer was anti-social and earned a below average income. >> the fbi profile we had folks come in and that was the whole gist that we were looking for, a white male in his 20s, 30s, single white male. >> although 90% of all serial killers are white, the fbi says they made no prediction of the race of the baton rouge serial killer despite the perceptions of local officials and information carried in the local media. >> i know there was confusion about that. i know what was written and was in the paper and it just wasn't there. >> nevertheless the local police obtained dna samples from over 1,000 men most of them white

between the ages of 20 and 40, most with a history of criminal activity. but not one of them was a match. that's when molecular biologist tony frudakis called with a warning that eyewitnesss and behavioral profiles are not always right. >> that information is oftentimes wrong. sometimes people lie and sometimes they are mistaken. >> so dr. frudakis made the police an offer. he promised he could identify the killer's physical characteristics. >> to be honest with you i didn't believe. i thought he must be a quack. how can he do this? but he purported he can determine the race of folks from dna and i said there is no way he can do that.

>> this new test called dna witness ascertains the ancestry of an individual based on their dna. it's rooted in the fact that all humans are descended from a common gene pool. >> instead of measuring the pigmentation genes we can make an indirect inference through a precise knowledge of your background. >> so the baton rouge police gave dr. frudakis the go ahead. the results changed the course of the investigation. based on statements from two eyewitnesss, baton rouge police on'tday ooklay, it's axwellmay. the igpay? otallytay. take an icturepay! onephay, onephay! really, pig latin?

radio announcer: mattress discounters 4th of july sale ends soon. ♪ mattress discounters based on statements from two eyewitnesss, baton rouge police were searching for a white male driving a white pickup truck in connection with five unsolved murders. with little to lose, investigators joined forces with a molecular biologist to perform a new test on the killer's dna. >> it's brand new technology. a lot of these people are unaware of what it can do. we have to go through the human genome and screen through large numbers of people to find these positions of dna so we can harness them and use the power

of them for what we're doing. >> to test dr. frudakis' claims investigators sent him 20 samples and asked him to identify the races of all of them. >> he did it to a tee. >> when he passed that test, dr. frudakis went to work on the killer's dna. the results? the dna test showed the killer was not a caucasian. >> the dna at the crime scene showed the individual was african and native american. >> the police couldn't believe it. >> i remember the phone line going silent. >> traditionally, serial killer is a white male and when it become a black male, it threw everybody off. >> police now realized the so-called eyewitnesss were wrong and they realized something else. around the same time of pam

kinamore's murder about 60 miles outside of baton rouge, someone knocked on the front door of a woman named diane alexander and asked to use the phone. when her back was turned the man ripped the phone cord from the wall and tried to strangle her. as she fought for her life her son came home unexpectedly. the attacker ran away still carrying the phone cord. >> the phone cord was sticking out of the vehicle. the son was able to describe the vehicle and the phone cord sticking out of it. >> and the police found similar phone cord near pam kinamore's

body. was it possible that the killer took diane alexander's telephone cord with him when he killed pam kinamore. to find out forensic experts compared the telephone cord to the ripped piece of cord of diane's alexander's home by performing a fracture match comparison. the ends usually remain intact. >> they took the remaining cord from diane alexander's house and were able to match it to the cord they found at pam kinamore's dump site. in a police line-up, diane alexander identified her attacker as derrick todd lee. if lee was the baton rouge serial killer, diane alexander was fortunate to be alive. derrick todd lee, a manual laborer, married with two children was identified by diane alexander in a police line-up as the man who assaulted her in her

derrick todd lee, a manual laborer, married with two children was identified by diane alexander in a police line-up as the man who assaulted her in her home. but he denied he was the baton rouge serial killer.

lee's dna sample was sent immediately to the forensics lab for testing. it matched the biological samples from all five victims. >> just a sense of relief and joy come over me. and it's like i had to smile. i said, we got him. derrick todd lee was arrested and charged with first degree murder. >> the first thing i would tell him is he's a coward. he picked on women that he took advantage of their good nature. >> after his arrest, investigators learned that lee's dna matched skin cells under the fingernails of yet another murder victim, an lsu student, 21-year-old jerry lynn desoto. prosecutors leave lee followed his victims so he knew when they would be home alone. he would knock on the door, ask to use their phone and once

inside, overpower them. fortunately for investigators, he left crucial dna evidence behind. at lee's trial, the sole survivor, diane alexander identified lee as the man who tried to kill her and dna from perspiration found on misalexander's blouse after the attack matched lee's dna profile, forensic proof he was the perpetrator. >> this is the real deal and now this lady has come to you and faces you and pointed you out. it was devastating. >> derrick todd lee was convicted of first degree murder and was sentenced to death. >> the death penalty is too good for him. they should execute him a little bit at a time.

you know, rape was not enough, murder was not enough. the coroner called it -- these murders, he said, are an overkill. >> some of the victims families are angry that police relied so heavily on the eyewitness accounts of a white male in a white pickup truck and the fact that most serial killers tend to be white. >> the profile itself was of course wrong. but it was also accepted by the task force as -- it was given the force of fact. when what it is is an educated guess. >> they were getting tons of tips from every direction. they were getting thousands of tips. so i wouldn't say that they -- i think they did the best they could and they worked very hard. >> in this case, dr. tony frudakis made scientific history. it was the first time this bio geographic testing was ever used in a criminal case.

the technology now has a 99% accuracy rate and new tests can even predict eye color with 92% accuracy. >> if can tell you the race, it might be able to tell you who you are looking for. but if it tells you the name and address and phone number it's time for me to leave this place. dna's too good then. >> this new test also shows the limitations of behavioral profiles and the fallibility of so-called eyewitnesss. >> i don't think it's too far out there to say that in the future there probably will be much less crime than there is today because people are going to realize that when they commit that rape or they commit that murder, they might as well take their driver's license out of their wallet and toss it on the ground. they're going to get that information anyway. >> if people are going to commit violent crimes they need to be

accountable and we need to take whatever means necessary to hold them accountability and that makes the job of police officer so easy. we have to take advantage of science as much as we can when it's for valid reasons a brilliant, young architect mysteriously died just before she testified in a criminal trial. her diary contained stories of sex, betrayal and intrigue. investigators needed to know if the stories were true. university park, texas, just outside of dallas, is better known as the bubble. it's a place of privilege and prestige, an address many would >>ke to have but few can afford.
