In all the pictures of him getting escorted by the police, the police are always some Noriega looking motherfuckers you know you don't want to me messing with. Dude is in for some shit, he done fucked up.
She was on the rag and a open lesbian if I recall. That shoots your theory down. They were thinking that it might be for money to gamble...as if he was going to loan her some money or something.
He made a run for it and was found in Chile about 1250km away.
They won't be able to extradite him. The ONLY thing that he could hope for would be a plea bargain/reduced sentence (highly unlikely) if he tells them where her body was.
He's from aruba on the run...he changes his hair...but tells the cabbies taking him to the Chilean border that he's from Aruba instead of something less obvious ...they report him...they find him in the chilean border town and chile sends him back across the border with the quickness.
