One has to wonder how it is that he knew facts about the condition of the body that only the killer should have known, as the story said.
Maybe he had some contact with the real killer
Maybe it was a lucky guess
Maybe the paper's wrong (nah - that couldn't happen!)
Anyway, it's good he's out of Thailand and not troubling that child anymore. Maybe they can come up with some sort of reason to keep him locked up.
I guess it explains why he was so laid-back on his airplane trip. He knew the DNA was going to clear him.
