Unless I'm missing something, I don't get what's with the conspiracy theories.
Is it not standard procedure to question the last person he was with? (Of course still with the assumption of innocence.)
Is the last person to be with someone, not the natural suspect number 1? (Again, still with the presumption of innocence.)
Is there really ABSOLUTELY NOTHING suspicious at all about leaving someone alone in a forest?!?
No one should be accused of wrong doing without due process, and only time will tell the truth, but I just don't see any conspiracy going on over here.
