Shawn and Gus confirm that it was Mr. McCallum that tried to make the ransom. McCallum sees Camden inside. During an argument, Camden fell and hit his head. He bled to death. Orso enters and McCallum has no choice but to shoot him, cover his tracks and make it look like Orso murdered Camden then committed suicide. On his way out, McCallum was bitten by Camden's angry dog. Shawn proves himself to the police by explaining and proving a "vision" of dog bite medication in McCallum's medicine cabinet that Gus actually saw when he was going to the bathroom.
