barely visible droplets of blood on the lowerhand of his t-shirt. blow back. this is what happens when you shoot somebody at close range. you get that blood on your shirt. correct. if you got high-velocity impact spatter on his t-shirt, he has to be within four feet of the child at the time that the child was killed. reporter: 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. that s probably one of the first times i ever heard kim cry. remember kim s old friend marcy? the prosecutor had her testify about an affair david had when kim was pregnant in late 1994. marcy told the court kim called
about road safety during the holidays. the big hat seemed tailor made for david cam. that is the band of brothers, huh? oh, yeah. special weapons tactical group. right. exactly. yeah. love those guys. i mean, we re talking about guys you would literally die for. but over time after the kids were born, david wanted to spend more time with his family. so in may 2000, he went to work as a manager in his uncle sam lockhart s business. it must have been hard to leave, dave. you wanted to have more of a life. but yet, you re i can see how much you like it really was being in law enforcement. i just felt like it was definitely i was in a point in my life when i needed to make that change and i wanted to make that change. and i presumed that i would remain close with these guys. that they would always be my friends. that they would always have my back if i ever needed em. reporter: by september 2000, the cams seemed to be living a picture-perfect life. things were go
of the bodies. then he says he heard david moving inside the house. and it clicked into my head, he s goin for a weapon. i mean, this guy is a former indiana state trooper. reporter: at which point he bolted from the scene. had i stayed there any longer, there s no doubt he would have killed me and he would have just lied and said to his buddies at the indiana state police, i came home and i found this black guy. reporter: after listening to boney 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 boney didn t account for was the dna that was gonna be found and he has no story for that. coming up. boney s story of course was i ran in, i did this, i never touched anybody, clearly not true. new dna evidence. he absolutely fought with camm. he touched jill. what will charles boney have
reporter: removed after she d been killed. what s more, the positioning of kim s body, he argued, was not what you d expect of a person who d been shot and fallen. her feet are under the car about, i think roughly ten, 12 inches under the car. her legs were at an angle which seemed unusual. unusual how? well, they weren t straight. they were at an angle. you just wouldn t expect em to be that way. reporter: and the infamous sweatshirt. the one that once belonged to charles boney was also part of the staging the 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. reporter: tucked all too neatly under brad camm s body as though put there on purpose to frame charles boney. 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
