I bet his "family" figures that as long as he's over across the sea he can't hurt us here at home. Another example of enabling parents that just won't believe that their kid is a killer, and probably think he's a saint, helping to save babies from burning buildings, yada, yada, yada...
He is most likely a repeat offender, and although it may be a stretch right now, I bet you could probably connect him with the location of quite a few dissapearances in that region.
I say prove him guilty and feed him to the sharks ALIVE!
