I think the Prosecution made out the best on that (Psychiatrist) testimony!
Tyler......lied, mouthed off to his Father, late for curfew, failed a drug screen, was positive for marijuana, truancy from school.
I agree! Another great point he got out of the Psychiatrist was the fact that the day before the murders, in group, TH was angry at his parents for asking if he was on Meth. This along with the testimony that he had been thinking of murdering his parents for a while...shows that it was his anger towards his parents that was the catalyst for the murders IMO. His parents were blocking him from having the party life he wanted by getting him all the help they were seeking for him. He made that clear to me by throwing a party right after he killed his parents. It was as though he was saying.....finally! Now I can party like I want. So tragic that the love of these parents to help him was a catalyst to him committing the murder IMO
