In my opinion, ive concluded that the police suspect foul play and has asked the Keller family to be silent as not to compromise evidence. Whether he was abducted by a stranger or an accidental event seems to be the question. The Kellers arent the kind of people to lay down. They have alot of family here. And as you see our Sheriffs Dept was the ones who requested the FBIs help. We all want the Kellers to have answers. I dont think hes alive. Ok there i said it. But im not in anyway pointing the finger at CG and CF. Im giving them the benefit of the doubt. This is just my thoughts, not facts.
