>> you've been sent to the slammer that you're going to do time in. you're learning how to become incarcerated.
>> i had to. i didn't have a choice. i had to figure out how to survive. and i made my mind up early on that's what i was going to do. whatever it took.
>> did you get confronted inside the joint, this is the guy that was a former cop, trooper?
>> not directly. but people would say things or you would hear people talking and so on.
>> did you think i'm done?
>> i was bewildered at first, but i thought there was still a possibility, or a glimmer of hope, there's this thing called an appeal.
>> there's an appeal, another trial.
>> overturning a first-degree murder conviction, long odds?
>> yes. until you read that transcript.
>> a new team of attorneys took the case to the state court of appeals.
>> narrator: it wasn't long odds in my mind. it was way over the top .
>> what was over the top they argued, was allowing all those women to testify to the sex t groping, the come ones.
>> narrator: it was weeks after weeks, woman after woman. how is that relevant to what happened on september 28th ?
>> jurors, this is a bad guy we have got here.
>> he's a louse of a husband and we're going to tell you more than that.
>> and it was intentional, too.
>> and two years after the guilty verdict t appeals court agreed. the women should never should have testified.
>> narrator: in review of some previous evidence and in view of some new evidence that's come to light. i have decide to pursue david camm for the murders of kimberly camm, bradley camm and jill cam.
>> with another trial looming, the defense team was intent on bringing sharply into focus a piece of evidence it believed would set david free. the sweatshirt with that unknown dna . sam lockhart says he approached the new investigators to run it through again. i wanted to show them the unknown dna in case this guy had been arrested now and we got new dna on this database, will you return it? no, they can't.
>> narrator: we started saying, please run the dna through the database. and he said we won't do it.
>> lo and behold, we find charles onae.
>> i had never heard the name before, it was a complete shock to me.
>> charles bonae, his business nickname was backbone, the same name inked into the sweatshirt's collar.
>> narrator: as brainy as ted bundy and as brawny as mike tyson .
>> it began in the 1980s when he was a student at indiana university . newspapers called him the shoe bandit and followed his bizarre crimes. there had been four separate incidents. he would wrestle the woman to the ground and take off her shoes.
>> one crime he wore kind of those zul masks. like creepy stuff you can't make up.
>> the police were on to it. after one arrest, he admitted in effect that he had a thing for ladies legs and feet. he pleaded guilty to those crimes and in time his attacks became more violent. he began threatening women at gu gunpoint. one incident involved three coeds.
>> narrator: he had been watching them, one night just walked into their apartment, held them at gunpoint to their head, took them out, kidnapped them to the car. luckily somebody saw him with the gun leading the women out, called bloomington police department .
>> he pleaded guilty again and was sentenced to 20 years in prison for armed robbery , but was released after serving only 7 years. at the time of the camm murders, he was out on parole.
>> narrator: he fit the profile?
>> yes, he has a foot fetish , and when they saw at first that it was not a sex crime , we kept saying, well, not everybody targets the same place in sex crimes .
>> kim camm had bruising on her toes, her shoes were on top of the bronco, her pants had been removed and bonae's sweatshirt with his dna was found at the crime scene .
>> narrator: it took one hour and one e-mail to find charles bonae. that could have been done in 2002 .
>> you would think on a case in which children and a mom are murdered, ambushed into a garage, the state would bend over backwards to do it right.
>> stan faith was the prosecutor in trial one.
>> narrator: the defense said, well, we asked you the prosecutors to send that out, to be tested against a national register of dna ?
>> i asked the lead investigator to do that and he said we didn't get anything.
>> when in fact he hadn't sent it out at all.
>> i think he sent it out. he hadn't sent the proper dna .
>> faith says he later learned that the detectives sent out the wrong dna sample from the sweatshirt. mike mcdaniel, the defense attorney isn't buying it.
>> narrator: when he says that the prosecution is lying to him.
>> lying means that you knowingly tell a falsehood. i didn't tell him a lie. i told him what i thought was true.
>> but whatever the truth is, now more than four years later, there was a name to that dna .
>> narrator: do you a allow yourself to think, here we are on our way to case closed finally?
>> we have got a name, we have got genetic forensic evidence , this is the shooter?
