the time zone in indiana. it was a call that david made to a client before he went to play ball. even more important, david had a solid alibi. 11 eye witnesses, the basketball players, to corroborate his story that he d been throughout the gym at the gym throughout that evening. did he leave the court that night? no. he couldn t have left without you guys seeing? he left out if he left at one point, we would have seen him. so throughout the time there s two sets of eyes looking in different directions. as a group, i think someone would have noticed that he was missing. sam locker, the uncle was playing that night. two is it possible that dave could have slipped away? is it possible that he snuck out, we ve gone ten or 15 minutes, killed his family without anyone noticing? absolutely not. that s impossible. but if david wasn t the killer,
i have no idea. reporter: boney admitted the sweatshirt had once been his, but said he d dumped it in a salvation army dropbox about a month before the murders. it shows up at a crime scene. not laundered, not washed. if it would have went though the salvation army drop box that would have been a clean sweatshirt. your dna, chances are probably wouldn t have been on there, but it is. i see where you re coming from. reporter: as for david camm? do you know david camm? no. 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. reporter: the interrogation went on for some 12 hours with boney sticking to his story. the 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
return with the second gun. i m asking this man you know, what time, what time should i be back here? well, why don t you come back on thursday at approximately 7:00, etcetera? 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 pocket? absolutely. reporter: it was thursday, september 28, the evening of the murders. i arrived at mr. camm s house at approximately 7 o clock. reporter: he said he handed over the gun to camm wrapped in his gray sweatshirt. where s this happening? right outside the garage. so we exchanged pleasantries and my sole purpose is to simply get the $250 for the second weapon. reporter: boney says after a few minutes in the bronco, the wife and kids arrived and pulled into the garage. and what happens? i hear a little bit of commotion. it just sounds like something s not right. it sounds like they re arguing. and then, all of a sudden, i hear an immediate pop.
and uh he could not let her leave, he could not let that secret out, that was the secret in the camm household. reporter: the defense countered. brought in experts to show there was no solid evidence the little girl had even been molested. the state s theory of why david murdered his family was purely made up. it was speculation. reporter: david camm had never been charged with sexual molestation but that didn t stop the prosecutor from closing his case with a big dramatic flourish. he took his finger and stuck it in dave s face and said, you molested your child. reporter: the jury took four days to reach its verdict. guilty on all three counts. we can tell you that david camm has now been convicted of 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 was just such a heinous accusation. reporter: but the saga was far from over. david camm s uncle still refused to retreat. s
reporter: the defense insisted boney was the sole killer in the garage that night and that back in 2000, investigators ignored evidence pointing to the convicted felon. to make that point, the defense called damon fay, a veteran homicide detective who now trains police in how to conduct murder investigations. i don t like testifying against other cops. i m very uncomfortable with it. reporter: fay recited flaw after flaw in the camm investigation. the most significant, he said was the handling of boney s sweatshirt. when a homicide detective actually gets some physical evidence that it s got somebody s name on it and dna, you hug it, you love it. it is such a rare event. and they thought of it as an artifact. which in non-legal terms means move on, forget about it. this is nothing. well, that s right. it would have changed everything. first of all, within two weeks tops, they would have had boney. reporter: and fay pointed out other blunders as well. the heavy reliance
