What gets to me is that Dean was most likely at the wrong place at the wrong time. Dave had no beef with Dean, and he did not hurt Dean to get to Dean's mother. It was pure sadism. Dave was "wronged" (fight with his gf) and someone had to pay.

Yes that’s unfortunate for Dean to have met Dave . Dave seems to be a typical cowardly abuser lashing out his anger towards small kids who can’t fight back. I wouldn’t be surprised if he did more abuse in the time he was out of jail. You don’t go from killing a child to another one with perfect life in between. It’s sad that the system has failed Dean and I wish that he was reported missing earlier . It all could have been prevented by keeping Dave locked up.
