and i consider it to be one of the most important cases i've worked in my career, based on the type of person jenna was. she was a young person that had her life ahead of her. and it's just a tragic event that it has to happen to someone like her. up next. they meet in cyberspace. >> they were meeting on the internet. >> she made pictures of herself. >> they meet face to face. >> they were getting all hot and heavy with each other. >> day later they were all dead. >> they all appeared to be execution-i'll ask murders. >> they disappear but not without a trace. >> probably every crime has a digital component. on average, 911 dispatchers in tulsa, oklahoma, receive

about 3,000 emergency calls a night. one night they got a call about a fire that sounded routine. >> i can see flames but i can't really see smoke. the back of the house is lit snup what's your name? >> my name's kenneth. >> where are you calling from. >> my cell phone. i'm on my way home from my friends house. >> 911 operator told kenneth to stay on the line until firemen received at the korean. then something strange happened. >> then it appears somebody may have been walking up to him. >> is there fire in there? okay. okay. >> hello. hello. >> when firemen arrived at the scene, they put out the blaze. and in a car parked in front of the home slumped over the steering wheel was the man who

called 911. he'd been shot to death. he was identified as 24-year-old kenneth maxwell, a truck driver who lived just a mile away. friends said he was going home from a party when he drove by. >> that's just horrific. no one ever thinks the good samaritan is going to be a victim. >> inside the house, firefighters found two bodies, a man in the kitchen shot in the head at point blank range. >> his body is right there and he's covered up with a rug. >> and a woman in a back bedroom. she's naked and shot several times in the head through a pillow like someone was trying to muffle that sound. >> the victims were identified as the homeowners, 51-year-old fred barney and his 42-year-old wife rebecca.

>> we were not able to find any kind of connection between kenneth maxwell and the barneys. >> but investigators learned that rebecca and fred barney had an unusual relationship. after six years of marriage, they were getting a divorce. they had no children, and the divorce was amicable, so they decided to live together and sleep in separate bedrooms until the divorce was final. >> so they didn't have an intimate relationship anymore, but they were still good friends. >> in the dining room, rebecca's clothing was folded in two neat piles. >> anybody that takes their glasses off and puts them on their clothing in the dining room, i'm thinking there's something that really went bad here. this is not a voluntary thing. somebody is forcing rebecca to do this. >> that's when you realize this

is not going to be your average murder. we can save big on killer hotels with priceline express deals. somewhere with a fitness center? hey you know what man, these guys aint no dragons. they're cool. these deals are legit. yeah, we're cool. she's cool. we're cool. i'm cool. hey, isn't that razor's old lady? not anymore. priceline savings without the bidding. on car insurance. everybody knows that. well, did you know that game show hosts should only host game shows? samantha, do you take kevin as your lawfully wedded husband... or would you rather have a new caaaaaar!!!! say hello to the season's hottest convertible... ohhh....and say goodbye to samantha.

arson experts determined the fire in fred and rebecca

barney's house was no accident. >> stove pulled out, gas line cut. it has always the appearances of somebody trying to conceal what had just taken place in that home. >> but the killer hadn't counted on someone driving by and reporting the fire. that call cost kenneth maxwell his life but saved a lot of evidence. >> bless his heart. he saved the investigation. he got 911 help there, the fire department put out the fire, and there was still plenty of evidence for us to analyze and work off of. >> kenneth maxwell's 911 call also prevented fire damage to the bodies. from the evidence at the scene, it appeared the killer caught fred barney completely off guard. he had been shot once in the back of the head. >> fred was wearing pajamas. it appeared that fred had been

making a sandwich in the kitchen. there was no real sign of a struggle. >> rebecca's body was found in the bedroom. she had been shot numerous times, leading investigators to conclude she'd been the primary target. >> he puts that pillow over her face and he shoots her, and think it's significant that he shot her more than once. he shoots her three times because he is pissed. >> ballistic tests reveal all three murder victims, kenneth maxwell and fred and rebecca barney were all killed with a .22 caliber weapon, the same .22 caliber weapon. the lack of forced entry indicated that fred and/or rebecca knew the killer. at first glance it appeared that nothing had been stolen. the victims' money and credit cards were untouched, but in a back bedroom something was

missing. >> the computer tower itself was gone, so that alarmed me right off the bat. >> why would a killer steal only the computer? >> to me that clearly showed very quickly that there's a computer angle on this crime. there's an internet angle on this crime. >> on the night of the murders, investigators discovered fred and rebecca were seen together in a bar called arnie's, a regular hangout of theirs. witnesses say they were with a man no one at the bar had seen before. >> they described him as a really tall guy. he was well over 6'4", 6'5". >> she's introducing him that night that this is my new internet boyfriend. >> witnesses say fred looked tired and disinterested. >> it seems to the patrons of the bar that knew fred wasn't very enamored with the date

rebecca was bringing. >> rebecca didn't introduce the acquaintance by name, but she did introduce him nevertheless. >> rebecca introduced the man that she was with as this is my ten-inch cowboy is how she referred to him at the bar. >> patrons and staff told investigators that fred, rebecca, and the cowboy left arnie's together at closing time. the bar was only five minutes from the barneys' house. >> arnie's closes around 2:00. the fire is being called in at 3:11. so a lot happened between the time they left the bar at arnie's an an hour before the murders happened. >> investigators knew nothing about the so-called cowboy. they had no name, no idea where he was from. but something found at the crime scene quickly filled in a lot of those gaps. number 1 of my 20 is for chacne. you know, chin acne. uh-huh. not to brag, but i have the chin of a teenager.

here you go. dinges for everyone! when i get hangry anything within arm's reach could be part of my number 20. hm, this is potpourri. mmmm. the new amex everyday credit card, with no annual fee. it's not food. make 20 or more purchases in a monthly billing period, and earn 20% more rewards. and a coat. it's membership that rewards you for the things you already buy, everyday. what's your 20?

at rebecca barney's autopsy, the medical examiner determine shed had been sexually assaulted, but collecting a biological sample wouldn't have be easy. >> this barney was on her menstrual cycle, and so there was so much of her dna that it

was literally overwhelming the other contributing dna that we were finding. >> fortunately a quick-thinking paramedic at the scene had swabbed parts of rebecca body while others were trying to save her life. >> this is pretty heads-up. i know this is a crime, she was found nude, what if there's dna. it turns out, yes, there was saliva on both rebecca's neck and her breasts. >> investigators encountered another setback. >> they did not get enough markers to work to compare to that database. >> investigators were fairly certain the dna belonged to the man seem with rebecca and fred in the bar just an hour before their deaths, but who was this man? the computer had been stolen from fred and rebecca's home, but investigators did find

several e-mails rebecca had printed. one was from a man with an unusual screen name. >> he had a screen name. i believe it was cowboyforyou67. >> the printout showed that rebecca and cowboyforyou 67 were exchanged over the internet. hers were more modest than his. >> he attached a ruler right next to his penis. >> you could tell rebecca was trying real hard. she was lonely. >> investigators were fairly certain these e-mails were from the man with rebecca and fred at the bar on the night of their murders. >> this is my ten-inch cowboy is

how i think she referred to him at the bar. certainly a material witness to perhaps the last hour or hours of the lives of fred and rebecca barney. >> the cowboy had also provided this picture, but since he was wearing sunglasses, there was no way to identify hymn. investigators turned to the tulsa police cyber crimes unit. >> i'd venture to say every crime that occurs these days probably has a digital component. there's probably going to be some kind of communication on the internet or cell search. >> a court authorized search revealed the screen name met someone new online just three days before the murders. wild ivy. >> they find out who wild ivy is. it's becky. >> cowboyforyou67 was identified as james kidwell, a31-year-old

computer science guy. >> he was divorced, money issues, and living at home. >> he had never been charged in a domestic violence incident. >> he had a warrant in relation to slashing tires of an ex-girlfriend. that's a red flag in a domestic situation. >> when police notified law enforcement in gore, oklahoma, that they planned to arrest james kidwell, they got a plenlt surprise. >> on that particular day when we were headed to gore to serve the warrant, the gore p.d. pulled kidwell over on some unrelated charges. >> police couldn't help but notice that kidwell's car was a mess. >> he's just got junk pouring out o of it. it's like he almost lives ow of that car. ite probably pretty obvious to rebecca pretty quick, all right, maybe he's well endowed, but he's not the kind of guy i want

to have a relationship with. >> when kidwell was arrested, police found a loaded rifle in his car, a weapons violation. >> he was asked if he knew rebecca barney and he told us he didn't know anyone by that name. >>s he cohis computer would tel investigators the truth.

when james kidwell was arrested for the murders of kenneth maxwell and fred and rebecca barney, he was with a young woman he met online less than 12 hours after the crime. when questioned, she told police she immediately regretted dating him. she said he always carried a loaded weapon. >> she was absolutely scared. just kind of invaded this young lady's life. she definitely felt threatened by it. >> kidwell lived with his mother. inside police didn't find the murder weapon or the computer stolen from the barneys' home, but the hard drive on kidwell's computer showed numerous contacts with many women. but he'd only deleted one series of files, the ones addressed to

wildivy2003, rebecca barney's screen name. >> just one folder, for some reason. he felt the need to delete that. to me it indicates a need to hide something. >> the evidence shows kidwell met rebecca online jild three days before the murder, and during that time exchanged more than 70 e-mails. the day before the murders, rebecca gave kidwell her telephone number. after the murders, all communications stopped. >> jimmy did not send any messages to her after the shooting. >> totally inconsistent behavior with the behavior three days before the homicide. >> and despite claims he didn't know who rebecca was, kidwell's computer showed he had a keen interest in her murder. >> someone using that computer for several days after the crime was looking up news stories to see what the latest news was on

the crime. >> kidwell was confronted with this cyber evidence. >> mr. kidwell begins to change his story. >> kidwell then admitted knowing rebecca barney and admitted he was hoping for a sexual encounter but said when fred barney accompanied them to the bar, it was clear to him the date was going nowhere. >> he told us that he was only there probably five to ten minutes before he left heading back to gore, oklahoma. >> ballistic testing revealed that kidwell's .22 caliber rifle was not the murder weapon, but records showed that kid well also owned a .22 caliber hand zbun, which police were unable to find. in kid well's dryer, investigators found two shirts. although they'd been washed, they still contained rust-colored stains. despite being washed and dried,

analysts were able to obtain dna from the stains and generate a profile. >> they could not exclude rebecca barney from being a contributor to that profile and only one in 12,000 individuals in the general population would match that profile. >> but was kidwell's dna at the crime scene? the profile from saliva on rebecca's body was very weak, so analysts returned to the dna from rebecca's rape kit. because she was menstruating, the dna was predominantly female, but there were minute amounts of male dna too. this time analysts used a process called ystr, which zeros in on one part of the sample, t the "y" chromosome which only is

found in males. it matched james kidwell's. investigators are convinced on the night of the murders, james kidwell was primed for a torrid sexual encounter. >> you're not driving 75 miles just to say hi. >> as a precaution, rebecca asked her estranged husband to accompany her on her first meeting with kidwell. he did so reluctantly since he just returned from a business trip. the evidence shows when they returned to the barneys' house, fred wept to his room and changed into his pajamas. prosecutors believe that rebecca refused kidwell's advances either because she didn't like him, because of her having her menstrual period, or both. regardless of the reason, kidwell got angry and left.

but not before getting a .22 caliber handgun from his car. by this time, i thinking kidwell was gone, fred was in the kitchen making a sandwich. kid well shot him at point blank range he then forced rebecca to take off her clothes. assaulted her in the bedroom. then killed her. to cover up the crime, he pulled the stove from the wall, cut the gas line, and started the fire. he left with the barney's computer thinking he was removing all the evidence. kenneth maxwell drove by on his way home from the party, saw the flames, and called 911. >> i see flames but i can't really see smoke. i mean the back of the house is

lit up. is that fire in there? >> when kidwell saw this, he shot maxwell too. police never recovered the barneys' computer or the murder weapon, but kidwell left plenty of electronic and biological evidence behind. >> the thing that sticks out about this case to me more than anything is kenneth maxwell and the sacrifice he made for being a good citizen. >> in november of 2004, james kidwell was tried and convicted of three counts of first-degree murder. he was sentenced to life in prison without parole. >> i think just being detailed and paying attention to detail in my opinion is what you have to do in each and every case to make sure that you don't miss anything. >> nothing you put on a computer is going to disappear unless

it's at the bottom of the lake or somehow destroyed in the fire. it's going to follow you even if you think you have destroyed it. up next, a woman is murdered in broad daylight. >> this is the monitor jumping out of the bushes and grabbing you and killing you. >> cell phone records and search dogs provided some leads. >> they were able to track a scent close to the trail. >> but if not for some crafty police work and the chance encounter, the entire investigation could have gone up in smoke. >> we have an individual that's still out, walking about, who can do this again. >> i don't know how much scarier it can get. during her lunch break in
