In regards to WC, I'm not even remotely looking at him. Here's what I assume happened, can't prove it, don't have sources, just imo. Mollie is missing and people in the area all know who THAT guy is, the one who raises the hackles of women in the area. So someone calls in and says "hey, probably nothing, but this guy has a history of issues with women, and he lives on a pig farm that he was raised on". Any LE is going to do a thorough check and bring the man in for questioning, it's part history of the guy and a CYA move. There's nothing about WC, including his history, that would link him to this kind of thing. He's nervous, and rightly so, it's a small town and girl is missing and he until she's found and the abductor admits it, he's in the crosshairs of every resident in that town. Personally I think he was promised by the reporter if he gave an interview they'd help him clear his name, he got flustered when he realized where things were going and couldn't stop the interview without looking even more guilty. Seems like a bit of a curmudgeon, definitely has boundary issues, but I don't see him going from his previous crimes to abduction. It doesn't fit. He and Mollie weren't in a previous relationship, and his previous issues were with women he was in relationship with.
