Please read other responses to this thread. He wasn't sitting in a Thailand jail. He was caught because we were looking for him. The initial accounts of this were inaccurate. The DA made that very clear today.
Thanks for clarifying the point re arrest in Thailand. Still, I'm not convinced this guy is anything other than a nut-job, pervert. The DNA is either a match or it isn't. Kerr's family will either have photos/videos of Kerr having Christmas dinner with them that night in another state, or they won't. The fact that Kerr may know details about the case not generally available to the public is meaningless if, in fact, he has a psycho obsession with the case. (For we all we know now, Kerr might have met a former police officer, detective, or investigator at an airport bar some place, who said more than he or she should have said after too many G & T's.)
