american. three dodge boys and one girl named angie whose birth occasion brother brent remembers was the biggest celebration of all. that was a pinnacle for my parents to have api baby girl. reporter: little angie was one ofep those kid who learned about independence early on and who grew up busy and strong and stubborn. angie was 5 11 and she was strong. reporter: but, of course big can be a problem for a girl. asro a teenager, she was too ta, too awkward. she struggled. and to make it worse, her parents marriage fell apart. that sag when angie went and just made friend with whoever accepted her. reporter: among angie s new friend was jessica n martinez. we want to be accepted not for what we looked like but for the people we were. reporter: back then, carol worried a lot about those new
name is innocence. honestly, i ve worked on, i think, 13 exoneration now. four of the ones in georgia, they found the actual perpetrator so to those four guys i m the guilty project. reporter: the coincidence you couldn t just make up. the very week carol left a phone message for him asking for help, idaho s science project had just taken on a new case. the case of the man convicted of killing carol s daughter, christopher tapp. the doctor called carol back. her word to me, i ll never forgot was i just want take know what happened to my daughter and, you know, it still brings the hair up on the back of my neck. reporter: curiosity of her surprise you? the knowledge surprised me. she has turned all of that love and devotion for her daughter into a very careful record of this case. reporter: so she read that report to him, the one that said the pubic hairs found on angie
detectives even perhaps inadvertently showed him where the murder occurred. oh, yes. there was more. police had always told carol that chris tapp knew things that only the killer would know. the location and position of angie s body, the clothes she was wearing. well, now carol could see for herself on tape the reason chris would know those things. carol was stunned to see police had shown tapp photos of the crime scene. there is times that i wanted to put my fist through the tv. reporter: and, finally, remember that the police theory of the crime after dna didn t match tapp or hobbs was three people admitted the murder together. the detectives spent hours
story is a secret that three people were involved? secrets can be kept. science reveals those secrets. somebody went in and committed a typical violent rape/murder and left typical evidence. there s no other person there by dna. where is he? where indeed? and carol dodge is still tortured, still pondering that last message from her angie that she had done something stupid. sounds to me like you believe she had crossed or double crossed somebody who was very dangerous. she crossed the line and didn t have any clue of what she had gotten herself into. and neither did she, carol admits. when she set out on a quest to find a killer, not finished, not yet. i m never going to stop looking. one day i m going to look that man in the eye.
you think it happened? i remember chris saying, you mean like a tv show? reporter: next, she saw police administering polygraph after polygraph and almost always with the same result, they would tell him he was deceptive and how when tapp was promised immunity, his story about ben hobbs changed. but perhaps what troubled carol the most was seeing how confused tapp was. even ten days after his first interviews, he still seemed not to know what house angie lived in. police, carol noticed, kept correcting him. for a guy who had taken part in a murder, tapp also seemed not to know much about the layout of angie s apartment. when they asked him to draw it, he couldn t do it.
