i said, yeah, he's in the tarrant county jail now. he's confessed. went. it impacted who we are. i don't even think about what could have been. i just live with what is. josh mankiewicz: in this interview, we've been framing you through the camera kind of close. and that's because sometimes we do that to disguise whether somebody is actually incarcerated when we're talking with them. but of course, as we can see from the wider shot, you are not incarcerated. you have never been charged with anything. arresting and charging glen mccurley has two effects. one is, it arrests and charges someone for that murder. and second, it isn't you. yes, that's true. thank you. i had doubts that this day would come. i really did. and that nobody would ever really know. nobody would know. and that suspicion would just linger with me till my dying day. josh mankiewicz (voiceover): 64-year-old rodney mccoy had been telling the truth all along. he'd lived with suspicion since he was 18. that truth? he was a victim himself. and now everyone knew it. i wake up every day.
