MR swallows really hard and looks like he's about to cry when Dr Phil offers to help him if he flew into a rage and he's dead.
his only grief is shown when a mental health professional offers to HELP him if he killed his son.
That tell me he did kill his son (in the campground, IMO) and that Dr Phil got to him by showing him attention, compassion and the offer of help. It's ALL about him. how his murder of his son is affecting him.
what a total case. psychopath, sociopath, narcissist, etc....
I caught that too, it was a very telling moment.
I think if LE calls him in again (which I believe they will) I would not be a bit surprised if he lawyers up.
