Before they strap Clint up for the polygraph test, Agent Trout spends about 90 minutes asking Clint to walk through what happened earlier that morning when his sister Holly went missing. Throughout the interview, Clint repeats what he's said all day, that he and his sister got along, that he didn't have anything to do with her disappearance, and he had no idea who did.

At the time, Clint was 25 years old. He was about 5'6", average build, brown hair. He'd been working part-time at a local nursing home while studying to get his bachelor's degree in social work at the University of Tennessee, Martin.
