I have no doubt that Michael Devlin is a monster..just how depraved a monster he actually is, I doubt most of us can even fathom.
I hope Shawn has the courage to NAIL this guy.
I hope Shawn realizes he has no more need to FEAR or be terrified of this monster. Then, I pray he starts talking - even if it means breaking the hearts of these parents - it would bring closure to them and Devlin would be punished.
