's bedroom window looked across the small parking lot at nona's bedroom window. now, he had to get the dna . >> how did you do that? >> i asked him for it. >> he said yes? >> basically. i asked if he would be willing to give fingerprints and a dna sample. if i can rule it out, then we are done. >> there was a problem. to get the sample tested he needed the jones family to pay for it. at first kevin's mother hesitated. it would cost $600 but the investigator insisted. >> eventually, she said something like, ■çoh, shucks, it's just money. >> so she paid for it and what a good investment it turned out to be. weeks later he got a call from one of kevin's lawyers, the dna tests were back. wouldn't you know. >> i said it matches. he said, it matches gary dunn. >> the results strongly suggested the dna on the condom wrapper was left by jeni neighbor, gary dunn. now he needed to check out the alibi for the day she was killed. dunn said he was shopping with his mother at the time of the murder, december 15, that was his alibi. he went looking for copies of receipts from those stores to back up the alibi. this is the store where supposedly gary dunn came to do shop( we checked out his alibi. the store had boxes and boxes of receipts. the old fashion sign slipped receipt. >> boxes going back years. he routed through piles of forgotten paper. how many boxes did you go through? >> i have no idea. i think i tried to forget that. >> just when he thought it was a wasted effort, he pulled out this scrap. did you find it? >> i found it. >> there it was. a receipt that showed gary and his mom were out shopping all right on december 13 not the 15th when they said they were. when nona was murder. it wasn't the same day at all. ç >> no. >> none of the receipts from the stores where they said they were shopping gave him an alibi for the time nona was killed. police and the prosecutor did not mention that . now, a new prosecutor was on the case and he found the dna results and faulty alibi compelling. when you're after kevin's acquittal, gary dunn was charged with murder. many people in russellville struggled to know what to think. their first impression was that kevin jones murdered nona dirksmeyer, but they believed this latest arrestee was the real killer? could the state of arkansas prove it? >> coming up. gary dunn was the one on trial. why did it ■çseem as if kevin jones was as well? >> the first thing is your son is on trial again even though he's not. . ahhh! my bottom's been saved! with its diamond weave texture, charmin ultra strong cleans better with fewer sheets and less effort. enjoy the go with charmin. smile! you found it. the feeling of finding psoriasis can't filter out the real you. so go ahead, live unfiltered with the one and only sotyktu, a once-daily pill for moderate to severe plaque psoriasis, and the chance at clear or almost clear skin. it's like the feeling of finding you're so ready for your close-up. or finding you don't have to hide your skin just your background. once-daily sotyktu was proven better, getting more people clearer skin than the leading pill. don't take if you're allergic to sotyktu; serious reactions can occur. sotyktu can lower your ability to fight infections, including tb. serious infections, cancers including lymphoma, muscle problems, and changes in certain labs have occurred. tell your doctor if you have an infection, liver or kidney problems, high triglycerides, or had a vaccine or plan to. sotyktu is a tyk2 inhibitor. tyk2 is part of the jak family. it's not known if sotyktu has the same risks as jak inhibitors. find what plaque psoriasis has been hiding. there's only one sotyktu, so ask for it by name. so clearly you. sotyktu. sleep more deeply and wake up rejuvenated. purple mattresses exclusive gel flex grid draws away heat, so clearly you. relieves pressure and instantly adapts. sleep better. live purple. right now save up to $800 off mattress sets at purple. visit purple.com or a store near you today keith morrison (voiceover): kevin jones's parents had won and lost. they'd won freedom for their son kevin, kevin jones parents won and lost. the won freedom with her son kevin but had lost a young woman they considered a daughter. they wanted justice so badly for nona that they spent their last dime to find her killer. they believe their sacrifice finally paid off when police arrested her neighbor, gary dunn , for her murder. >> ■çi believe he committed thi crime, but that's my belief based upon what i saw. >> the trial opened in april 2010. jones listened as the state which had already tried his son now argue that dunn was a sexually violent man who had been stalking the young beauty queen his bedroom he could see across the parking lot. his own wife testified he was violent in bed with her and weeks before nona's bed, she caught him hanging around nona's front door in the middle of the night. so, a jury could be sure that dunn killed nona after forcing asexual encounter. the condom wrapper proved to. >> this wrapper that was found that had the dna on it■ç that d not have kevin's dna on it, that had his dna on it. >> dna evidence, disturbing background, and alibi that turned out to be no alibi at all. it was hard to see how his public defender could argue against their client's lies and dna. that is what they did. and with gusto. what you are saying is the state is wrong. >> the state was wrong. >> what's more, they could prove it. for starters, they said the state was not honest on the dna. it was only a mixed partial match to gary dunn they said. >> any thousands, millions of people are also not excluded. >> let me ask. if what you are saying, gary dunn did not touch that condom wrapper? >> that is what we are saying. he was across the parking lot in his apartment. >>is minding his own business when nona was murder. it's true the defense said that he was not a shopping as he first claimed. it's at got in his days mixed up. it was two weeks after the crime when detectives asked her a detailed alibi. >> they asked for receipts and they found receipts. they gave it to the police department. >> it wasn't for that day? >> he cooperated and gave them what they asked. >> the defense that it was not e his alibi they should question. if anything, the lawyers said they should look at someone else for nona's murder . her old boyfriend. that moment, jones realized with dread just where this trial was heading. >> first thing you get hit with is her son is on trial again even though he's not on trial. he is. that's part of the defense that they use. >> how right he was. the attorneys tried to persuade the jury that kevin jones, the first suspect in the case had one shaky story after another. the 911 call were kevin's mother was crying. >> her name is nona dirksmeyer. >> the defense said janice jones and kevin's friend gave conflicting details of how they came upon nona's body and what they were doing to save her. >> they are lying. all three are lying. >> the pizza boy, his mother, kevin is lying?

>> i don't know what they know but they are covering for him. >> the lawyers said he could not explain one thing away. the bloody paw imprint in nona's apartment. it was his and not gary dunn's. did it work? yes, it did. after three days of deliberation, the jurors said they were hopelessly deadlocked. the judge declared a mistrial. the prosecutor was not giving up. he promptly refiled murder charges and gary dunn's second trial began in 2011. >> gary dunn tried a second time after his first trial ended in a hung jury. >> the judge allowed the prosecutor to reveal a dark fact about gary dunn. he was a convicted felon before nona was murder. jurors heard from a woman named kelly joe fitz harris who had the grave misfortune of jogging past gary dunn on the wrong date in the wrong place. in 2002. it's a popular trail with runners but very isolated. kelly joe came running by herself from that direction. she saw a man sitting here on this bench. as she ran up the trail this way, she heard footsteps behind her, turned around, and the man had a huge stick and he hit heri over the head with a. he knocked her down and hit her kn repeatedly. she realized the only way to escape was to wriggle free. she ran up the trail that way as quickly as she possibly could. calling for help, pretending there was someone nearby. the police came a little later. they found gary dunn hiding in the water. they arrested him. he spent 18 months in jail. he and then, newly out on parole, he moved into nona's apartment complex and set up house across the parking lot months before nona's death. the lawyers admitted it was a blow to their defense. >> we had to deal with it he may get -- not make it any worse. >> or was it already done? this time they knew the man sitting in the defendant's chair wasn't as prone to violence but a convicted criminal. so, the first impression that kevin jones murdered the beauty queen finally be undone?
