>> at first i thought it was just jill laying there. i didn't realize it was kim until i got out of my truck a and ran into the garage and that's when i saw that it was kim. >> how do you take this? it's too much to absorb. kim was in a long pool of blood running from her head. the doors to her bronco were open. when do you look into the vehicle? >> i don't remember how long it was, but after checking on kim, being assured in my mind that she was gone, i just suddenly thought about the kids, where are the kids? and my first instinct was to look into the bronco. a and i got up on the passenger's seat and i could see more into the back and that's when i saw brad and jill. >> narrator: jill, still buckled in on the passenger's side was slumped over, there was blood in her hair. next brad seemed to be clamoring over the seat. >> was it apparent in your shock, that this was a gunshot event? >> i did not know how they died. >> so you jumped over the console? >> i thought maybe he might have a chance. >> narrator: david had been an indiana state trooper for over 11 years. that night in the garage, david said, his police training kicked in. it seemed to him that his daughter jill was dead, but if there was even a whisper of a chance for his son brad, david knew he had too get him out of the bronco and give him cpr. >> i went in and got him and came out the same way i came in. >> you put him down on the garage floor and began working on him? >> yes. i just remember looking at his face. and his eyes, there was no moisture, and they were half shut. it was pretty obvious that he was gone. >> and this has all happened in, what, 45 seconds of your life?

>> yes. >> narrator: the prosecutor moved on to the crime scene and focused on what happened to kim in the garage that night. >> we thought that the pants had been pulled down. >> you have accused the husband of the murder, why are you telling the jury that he was pulling h in ing her panels dow. >> trying to get the jury to think that somebody was in there to molest her. >> that there had been a break in. >> narrator: investigators had never located the murder weapon. the only physical evidence the cops had that the gun was in david's hand that night was this. barely visible drops of blood on the lower left of camm's t-shirt. >> blow back, this is what happens when you shoot somebody at close range? >> yes. >> you get that blood on your shirt. >> he got high impact spatter on hiss t-shirt, he has to be within four feet of the child at the time that the child was killed. >> narrator: the prosecution believed david camm shot from inside the car, targeting jill in the back seat. that's how her blood sprayed on his shirt. but why? why would david camm kill his family? the reason for those killings, the prosecutor, declared was that david camm was a philandering husband. >> it probably was one of the first times that i really ever heard kim cry. >> remember kim's old friend, marcy mccloud? the prosecutor had her testify about an affair david had when kim was pregnant in late 1994. marcie testified that kim called her in tears to say that she and david were separating. marcie soon after visited kim. >> she was upset. you know, and saddened by it, especially just having a baby. >> narrator: and there was more. just three weeks before the murders, marcy had another troubling phone call from kim. >> her demeanor was different, her attitude and she didn't want to hang up the phone, but yet she didn't want to talk. >> narrator: the old friends made plans for kim a and the children to visit marcy. then kim said something she never explained. >> she felt like history was repeating itself. we didn't go into what that meant because she said, we'll talk about it when i get there. >> kim never made it. at trial t clear i, the clear i was that david was catting around again. >> there's people he pulls over, flirts with them and eventually seduces them. >> in court the prosecutor called a parade of women presenting them as david camm's conquests, more than a dozen of them recounting the fondling, the sex in the patrol car. >> he wanted to have women and his wife was getting in the way? >> yes. >> she was an on stack bstacle kind of women he wanted to pursue? >> yes. >> narrator: the prosecutor had a capper, something really dreadful. the medical examiner's testimony that the injuries on the murdered daughter, 5-year-old jill were consistent with sexual abuse. >> not a little girl falling on the monkey bars. >> no, not the monkey bars, it wasn't a bicycle or anything like that. >> narrator: so the killer with blow back blood spatter on his t-shirt. the defense lawyers had their work cut out for them. >> you had an uphill fight as a defense attorney. >> yes. and that was not unusual, but this was so much more high profile. >> reporter: coming up, the timeline of the crime. >> that was their smoking gun. >> reporter: the defense is about to stop the clock. that's insane. yep, and you can customize it. i can download anything i want.

>> i figured he was another red neck state cop. we had done a couple of cases, him on one side, me on the other. >> narrator: but mcdaniel became convinced of david's innocence and came on board to defend him. >> this is one of the most terrible cases that a defense lawyer never wants. you don't want an innocent client. you call them a ravager because they make you crazy. >> before the trial, daniel knew he had to confront all these women. >> the jury's getting a picture of this hard working wife, nose to the grindstone, taking care of the babies and running the household. >> yep. >> while he's out with pole dancers? >> he has women coming in with varying degreeses of sexual contact or innuendinnuendo. >> he put david on the stand to stay he knew he messed up. >> i regret all that stuff. it's so unfortunate the disrespect that i showed my wife. but good god, we don't jump to that to saying that automatically makes a person a murder, it's just ridiculous. >> narrator: then the defense had to confront the ugly allegation that 5-year-old jill camm had been molested. but in fact the medical examiner's report had not exact said that. it simply stated that the perus bruises were the result of blunt trauma. >> there may be some evidence here of child molestation. this is a very, very tough thing to combat. >> it's literally impossible. >> the defense turned to the physical evidence. the states's strongest evidence, the forensic case for david's guilt was the blood spatter. the defense expert testified the blood got on david's t-shirt very simply, when david reached into the back seat to move his son, his shirt brushed against his daughter's hair. >> there was some blood on some of her hair around the wound. so defense testimony was that was transfer. from that contact with the ends of the strands of her hair. >> narrator: and then the timeline. the defense lawyer challenged the prosecution's theory that david snuck out in the middle of his basketball game, killed his family and then returned to play ball. the defense attorney focused on the phone call made from the camm house at 7:19 p.m. when david said he was at the church gym. the state had tethered its timeline to that phone call. >> that was their smoking gun, which they had a bunch of those and every time they would have a smoking gun, we would just unload it. >> narrator: the defense unloaded by calling an expert from verizon, saying the timeline was incorrect, because of indiana's jumbled time zones. >> their 7:19 phone call was actually a 6:19 phone call. >> narrator: a call that david made to a client before he left to play basketball. plus there was a solid alibi. the basketball players, the corroborate that he had been to the gym throughout that evening. >> did he leave the court that night? >> no, he couldn't have left without one of you guys -- >> i would see him at one point in time running down the court. and then maybe just would have saw him at another point in time. so throughout that time, there's ten sets of eyes looking in ten different directions, as a group, i think someone would have noticed that he was missing. >> narrator: sam lockhart the uncle was playing basketball that night too? >> is it possible that david would have snuck out? >> is it possible that he could have snuck out, killed his family and snuck back in? absolutely not. >> narrator: if david wasn't the killer, who was? the prosecution had its answer, it was the one that owned that sweatshirt, the one lying on the garage floor. the defense attorney mike mcdaniel had recognized the sweatshirt as prison issue. >> in the collar of the sweatshirt is the word backbone, and i'm thinking, that's a nickname. >> narrator: tests on that sweatshirt revealed dna from various persons, including an unknown male. but there was no match when it was run through the database. there was proof that someone else was in the garage that night. >> we knew that there was probably the key to solving this. we didn't know that person by name, by god we knew him by dn a a profile. >> narrator: finally it was up to the jurors. as reporters lingered in the hallway, the jury deliberated for three days. >> guilty. >> narrator: david camm was found guilty of killing his wife and children. >> the jury comes back and guilty as charged. >> that's what we wanted and now we feel like kim, brad and jill can be at rest now. >> but his sister, an emotional outburst. >> before i even knew it, i was standing up and i was screaming, you're wrong, you're wrong, you're wrong. and a few people had to take me out of the courtroom. >> and you're being walked off in chains? you're not leaving that courthouse? >> no. and knowing what lies ahead of me. going to prison, a former police officer. there a's absolutely nothing i can do about it. >> narrator: david camm was sent to the state penitentiary to serve a terms of 195 years. but his uncle sam was hanging in. >> you didn't think you were finished at that point? >> unless they would have killed me, that's how they could have stopped me. no, it wasn't over. >> narrator: it wasn't over not by a long shot. but not even uncle sam could predict the stunning turn that would lay ahead. >> reporter: coming up, a break in the case, someone new enters the picture. >> as brain any as ted bundy and as brauny and mike tyson. never have 80 calories tasted so satisfying. light & fit greek. taste satisfaction without sacrifice. ♪ dannon for centuries." ♪ this levian collection is amazing. maybe it's time to start your own.

no, they can't. >> we started saying, please run the dna through the database. and he said we won't do it. >> lo and behold, we find charles bonae. >> i had never heard the name before, it was a complete shock to me. >> narrator: charles bonae, his business nickname was backbone, the same name inked into the sweatshirt's collar. >> 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. >> narrator: 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. >> 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. >> narrator: 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. >> 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. >> narrator: 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. >> 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. >> narrator: stan faith was the prosecutor in trial one. >> 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. >> narrator: 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. >> 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. >> narrator: but whatever the truth is, now more than four years later, there was a name to that dna. >> do you a allow yourself to think, here we are on our way to case closed finally?

>> do you know david camm. >> no. >> have you ever met david camm? >> no. >> do you remember the murder of david camm's family? >> on television, yes. >> do you know where david camm lives? >> only on television. i don't even know what his address is. >> narrator: the interrogation went on for some 12 hours, with bonae sticking to his story. but detectives released him with a warning. >> make no mistake about it, if anything else links you to it, you're done, stick a fork in you. and see, that would normally worry me. i wasn't there. >> narrator: then two weeks after letting bonae walk, there was something else, something big. >> early yesterday morning, i was notified of some additional scientific evidence that linked mr. bonae to the homicide. >> the prosecutor revealed that a palm print found on the exterior passenger side of the bronco door frame was left there by none other than charles bonae. investigators had been aware of the palm print for more than four years, only now did they know whose it was. bonae was pulled back into the interrogation room and the questioning became more confrontational. >> you've got some explaining to go here, charles. your palm print is on that bronco. you're there. now this is the time, this is the place, this is your last stage that you're going to have to tell us what the hell happened there. this is it. >> this can't be happening. >> charles. >> narrator: after hours of denial, bonae changed hid story, yes, he did know david camm, they met playing pick up basketball. in another round of questioning, the story changed and changed again. finally bonae put himself at the crime scene. >> the reason why i was -- >> police said david camm asked him to get an untraceable gun. he said he was the guy caught in the wrong place at the wrong time. >> as events started to unfold in the investigation, it became apparent that this case was intertwined between two people. >> now the prosecutor had a new theory, david camm did not act alone, he had a con conspirato. charles's signature was all over the scene. >> he attacks women, defenseless, innocent women, he takes their shoes, their socks, he holds guns to their heads and threatens to shoot them in the head. all of those things from his previous crimes is exactly what happened to kim. why can't they see this stuff? they just turned a blind eye to the facts. >> narrator: but the prosecutor had a different set of fangts. >> we know that the defense has maintained that this is now the killer, that i should dismiss the charges against david camm. the evidence is not there. >> narrator: in january 2006, charles bonae and david camm took trial separately in two different courthouse. while i wasn't accused of being the shooter, bonae was tried on three counts of murder, he was sentenced to 325 years, and the prosecution team rejected any -- those tiny specs of blood that were on david's shirt, but not on bonae's sweatshirt. >> his shirt does not have high velocity blood spatter on it. >> so a state trooper is now going to be a co-conspirator. >> there's no text messages, there's no phone calls, there's no smoke signals. there's nothing between david camm and charles bonae. >> the case against camm was pretty much the same, absent the female witnesses, the appeals court had thrown out. this time the state focused on the allegation that david molested his 5-year-old daughter as a motive for the murders. >> well the motive was kimberly was leaving david camm and she was leaving him because of the child molesting. and he could not let her leave, he could not let that secret out. that was the secret in the camm household. >> narrator: the defense countered, brought in experts to show there was no solid evidence the little girl had even ben molested. >> the state's theory of why david murdered his family was purely made up. it was speculation. >> narrator: david camm had never been charged with sexual molestation. but that didn't stop the prosecutor from closing his case with the big dramatic flourish. >> he took his finger and stuck it in dave's face and said you molested your child. >> narrator: the jury took four days to reach its verdict. >> guilty on all three counts, i can tell you that david camm has now been convicted in the murder of his wife and the murder of his two kids brad and jill. >> guilty again. >> guilty again. with the same inflammatory evidence. this is just such a heinous act zagts. >> narrator: but the saga was far from over. david'ssed to retreat. >> reporter: coming up. they certainly weren't done, but prosecutors weren't done either. >> the placement of the sweatshirt led you to believe that david camm put it there. >> and charles bonae, he was just getting started. >> he wants me to deliver a second handgun. >> when "dateline" continues. well...your boss loves the beach. really?

>> right. >> all rise. >> narrator: the indiana supreme court heard the appeal. >> these crimes are also connected. >> narrator: they argued that the evidence that david molested his daughter was pure speculation and should not have been allowed in the trial. >> there's absolutely no evidence at all that camm was the perpetrator of that, right? >> narrator: in 2009, the upper court agreed. >> convictions reversed. two words. that's all i needed. >> narrator: a second victory for the camm team. the conviction was overturned and the judge ordered a new trial. >> statistically a successful appeal of a first-degree murder charge is a long shot. and yet you got it. >> i got it twice. that doesn't happen. doesn't happen. you know, if you don't believe in something bigger, you need to really evaluate your spirituality because, you know, man, that was a god thing. . >> narrator: in august 2013, more than a dozen years after the murders, david camm faced his third jury. a special prosecutor sam lefco was hired to take the case. >> when i first got it, it was just overwhelming. i have tried a lot of death penalty cases, murder cases, i have never tried anything like this. i never seen anything as complicated. >> narrator: with no philandering husband, no molesting father, what remained was the theory of the crime that david left the basketball game, killed his family, then went back to play some more. once again t prosecutor argued that the scene in the garage was staged to look like a sex crime. >> and her pants had been removed? >> correct. >> narrator: removed after she had been killed. what's more, the positioning of kim's body, he argued, was not what you would expect of a person that had been shot and fall fallen. >> her feet are under the car, roughly 10, 12 inches under the car. her legs were bent at an angle which seemed unusual. >> unusual how? >> they weren't straight, they were at an angle that you wouldn't expect them to be that way. >> narrator: and the infamous sweatshirt, the one that once belonged to charles bonae was also part of the staging t prosecutor argued. >> the placement of the sweatshirt was incriminating. i thought the way it was put there led you to believe that david camm put it there. >> narrator: tucked all too neatly under bradley camm's body, as though put there on purpose to frame charles bonae. remember, no murder weapon was ever found. the heart of the prosecution's case was still that freckling of blood at the bottom of david's shirt. powerful, incriminating evidence, it argued, making david as the shooter. >> the little girl was seat belted on this side, as you're looking in. >> tom bevel, a blood stain pattern analyst was a witness for the prosecution. in a bronco similar to the one owned by the camms, he demonstrated for us the way he believes david was wedged inside the car to get those specs of blood on the bottom of his shirt. >> what's a likely posture for the shooter? >> leaning in somewhat like this north to get the correct trajectory for her. >> i notice your shooting hand is up pretty high. >> it is. >> is that an awkward shot? >> it's not necessarily awkward, but we have to go with the physical evidence, and the physical evidence isn't like this. >> narrator: but why so few spots? bevel said it's because most of the blow back hit the inside roof of the vehicle. like much of the other evidence, the blood spatter testimony was essentially the same as in the other two trials. what would be enormously different this time is the star witness. the jury was going to hear from charles bonae himself. a huge risk for prosecutor lefco. >> you wonder what kind of witness this charles bonae was going to be for you? >> i felt like i didn't have a choice, i suspect they would have. but also i thought the jury ought to hear it. >> narrator: this is the story bonae told in court. he says he met camm playing basketball at a local park. we talked to bonae in prison. >> it was just a pick up game of basketball. i didn't know him or really anyone there. i'm fresh out of prison, the scene is different. >> narrator: after the game, he said camm was bragging, talking smack about how easily he had beaten bonae. >> at that point, i said, i may have lost the game, but at least i have my freedom. he's like freedom, i was like yeah, i just got out of prison. >> camm told him he used to be a state trooper. >> at the end of that day, did you know him by name? >> no, i didn't know him by name until our second channels meeting. >> narrator: that meeting was about a week or so before the murders. they ran into each other at a convenience store and got to talking in the parking lot. >> the gist of our conversation was are you employed? are you staying out of trouble? then it evolved into what types of things did you do to get into prison in the first place? he was creating hiss own form of intel. he was learning quite a few things about charles bonae. >> he told him he had been inside for robbery. >> when i slowly started to let him know about some of the things i did in the past. he asked me, well, are you still able to get untraceable weapons? >> untraceable? >> that's what it led to. a clean gun. something that can't be traced by law enforcement and ballis c ballistics. >> so bonae said he met camm the same day, met him in a parking lot and handed over the weapon. he said he paid bonae $250. but one begin is not enough. >> so he wants me to deliver a secondhand gun. so i follow him back to hiss house. i can see visibly exactly where he lives. >> narrator: they spoke outside the house for just five minutes. bonae asked when he should return for the second gun? >> i'm asking this man, what time? what time should i be back here? >> why don't you come back on thursday at approximately 7:00, et cetera. so i knew what time to be back. >> so meet me here on thursday night in the evening and you'll have some more cash in your your pact? >> absolutely. >> narrator: it was thursday september 28, the evening of the murders. >> i arrived at mr. camm's house at approximately 7:00. >> narrator: he said he hadn' d it over to camm wrapped in his gray sweatshirt. >> my sole purpose is simply to get the $250 for the second weapon. >> narrator: bonae says a few minutes later, the wife and kids arrived and pulled into the garage. >> and what happens? >> i hear a little bit of commotion. it sounds like something's not right. it sounds like they're arguing and then all of a sudden, i hear an immediate pop. and before i heard the pop, i heard her say, no. and it was a commanding no. like stop. then i heard a pop, then i heard the word daddy. >> two more pops. >> did you know what that was? it sounded like handguns. >> so what did you think? >> i was thinking this was a crime scene. as he emerged from the garage and pointed the handgun at me, i was frozen. >> so you're a target? >> absolutely. so he needs to kill charles bonae. >> but the gun jammed. >> the thing is, once i realized that your gun doesn't have projectiles in it. now my job is to get you. >> you're going for him? >> absolutely. >> narrator: now as bonae tells it, the scene moved into the garage. >> as i go into the garage, i'm chasing after mr. camm, i heard him say you did this. and i took that as, this is your crime. >> narrator: as camm went inside the house, bonae says he saw the victims. the wife by the car door. he remembers her being fully clothed. then he says he stumbled. >> i trip over shoes. i clearly touch something that is now a part of what will be a murder scene. so yeah, i did pick them up, i did try to wipe them off. >> kim's shoes, he placed them on top of the bronco, then he looked inside the vehicle and says he saw the two children. mindful of leaving dna and prints, he session he touched none of the bodies. then he says he heard david moving inside the house. >> and it clicked inside my head, he's going for a weapon. i mean this guy is a former indiana state trooper. >> narrator: at that point he bolted from the scene. >> he would have lied and said to his buddies at the indiana state police, i came home and found this black guy. >> narrator: after hearing bonae testify, the defense was ready to pounce. >> that's his story, and it makes absolutely no sense, but it explains away all the evidence that they had against him at the time. but what bonae didn't account for was the dna that was going to be found and he had no story for that. >> reporter: coming up, new dna evidence. >> he absolutely fought with camm, he touched jill. >> what will charles bonae have to say now?

>> yes, they did, they found a palm print up in this area. but it makes perfect sense if you're leaning in and you want to stabilize yourself, especially if you're making a shot. >> narrator: now the police have scientific evidence. >> bonae's story of course was i ran in, i did this, i never touched anybody clearly not true. >> there is something in the field of dna analysis called touch dna. lab experts use human cells to make an identifying hit on a suspect. touch dna from bonae's skin cells was found on kim camm's sweater, on her underwear and on jill's shirt. >> the dna conclusively proofs that he absolutely fought with kim, that he touched jill. >> and the defense hoped it's cross-examination of bonae would be still more proof. camm had to steel himself to watch bonae on the stand. >> there was no way for me to actually prepare myself for that. and it was a situation where i really had to think about what was at stake and doing what was right in that moment, having to sit there and look at this guy that i knew killed my family and not react. >> narrator: the defense said bonae's story was absurd. for starters why would an ex-cop ask an excon for a gun. >> the guy who got out of prison doesn't smell a rat? he doesn't think i'm being set up? it makes absolutely no sense. >> narrator: the defense took on b onae's story in cross-examination. we had some of the same questions when we spoke to him. >> how many versions did it take to get to the story you just told? four, five times maybe in. >> i finally find out, the more i keep lying, i just dig myself deeper and deer, i'm not going to get out of it. and when i did start telling the truth about things, i didn't feel comfortable revealing too much too soon because i didn't want to be a part of the case to begin with. so once again, i resorted to telling a lot of stories. >> but the big picture here charles for a lot of people is it sounds like a crock, that a felon, just out of the slammer would hook up with a recently retired state police officer and do this gun exchange. it just doesn't seem to make sense. it doesn't pass the sniff test. >> there's a lot of things about this case that doesn't make sense. >> if i were you, i would have alarms going off inside my head, here you are on probation, how do you know that this former cop is really a former cop and he's not setting you up with a sting. >> although that did cross my mind and i had concerns about him. there was something about him, if you have spent any time with mr. camm, he has a way of putting you at ease, he has a way of making you feel like he legit and making you feel okay. i didn't care what the gun was for. >> this guy was on a special weapons team with the indiana state police. this premeditated crime, he's going trust a hanged gun that's come off the street, that he haslemn't checked out, he's unwrapped it from a sweatshirt and immediately used it for his business. >> it was the gun. those are questions that i can't possibly answer. why did he want me there at the crime scene? we know why because he wanted mess to take the blame for all of this. >> narrator: so as bonae tells it, the transaction happens, he hears the gun fire in the garage and then david camm tries to shoot him. >> why didn't you just belt out of there? >> even on a prison level, if i got comes at me with a shank, i'm going goat that shank from him, a him. my intent was to kill david camm that day, you tried to kill me, and now i'm going to kill you. but before i had a chance to kill him, i stumbled across this beautiful woman, dead, lifeless on the ground. >> then bonae says he stumbled over the woman's shoes and took the time to place them on top of the bronco. >> but then you're down on the floor t way you tell it. you tripped? >> yes, i tripped over the shoes. >> and your emotions are going wild, this man's trying to kill you, you're at a crime scene, you trip, oh, shoes, i got to put these on the vehicle. doesn't make any sense. >> i'm wiping the shoes off, and i see one little leg or something hanging out the passenger side. i go to investigate to see if there's anyone else in the back of the vehicle. and when i leaned in to look, i put the shoes on top. i don't even remember doing it. >> doesn't remember doing it, and he says he doesn't know why. i wasn't thinking about why i did that. but i was cognizant and really thinking about the dna or possible fingerprints from having tripped and touched those shoes. >> but you know, that palm print charles is just where you would brace yourself to lean across and shoot that little boy. >> that's according to a defense expert witness. you got to understand, the prosecution's got that same evidence, they don't see it that way. >> if you're so concerned about tidying up, why would you be so clumsy as to leave a hand print on the vehicle. >> i see the children inside, i didn't know i left that palm print. i i had known, i would have taken the time to wipe it ah! i just wanted to get out of there. >> narrator: how does he explain his touch dna on jill and kim's clothes. >> my skin cells are clearly on him, so anything that he touches can be transferred. >> narrator: while the defense couldn't tell the jury about bonae's past, the foot fetish and the armed robberies. we knew the past and asked him about it. >> when you understand your criminal history, the fetishes, what happened in that garage, seems to fit your appetites. this guy's history just played out on a violent scale that he had never been through before. >> first of all, my history does not consist of killing women, shooting people period, i have not had anything like that in my past. yes, i have been in possession of handguns, yes when i was 20 years old, i did some armed robberies for cash. >> were you in that garage that night with a gun in your hand taking control of kim camm? >> no, sir. >> the kids started to cry, shut up. >> in your panic, forget the sweat forget about the trophies -- got totally out of control, and you massacred a family. charles bonae, did you kill that family? >> in fact that's the most ridiculous thing i have ever heard. a guy with a foot fetish kills an entire family just to satisfy his foot fetish? in a place where he's never been before? it never happened. >> what are you hoping the jury hears today? >> i have no comment. >> david camm's third trial came to an end after nine weeks. >> it's over, right now. >> would the jurors believe the tale they heard? the felon duped into a crime scene by an ex-cop? for the first time in 13 years, his fate was in their hands. >> i was scared to death. >> i kind of had that same feeling. but none of us had the nerve to utter it. >> and coming up sunday on "dateline." >> two women. both lock in the struggles to survive. >> they took me out of the car. they had me kneel. i was sure that that was it. they were going to kill me. >> world traveler, reporter. adventurer, then she became a prisoner. >> tonight, they have brought me out to kill me. >> kidnapped, in once of the most dangerous places on earth. >> i was hanging on by a thread. >> her best hope for freedom -- >> mama. >> i love you. >> her mother, who turned investigator, then negotiator. could she saves her only daughter?
