God, meth, and placing blame

I've been following the Zavattero killing in the Chico papers. Why he did it is still somewhat obscured. (Whether or not Nick killed his father is less of an open question, what with the 9-1-1 confession). Here's the district attorney talking about the case:

"He has claimed that God told him to kill his father as a test of faith," Ramsey said. "God had spoken to him or given him a sign through the TV the day before."
Zavattero told sheriff's deputies he is Jesus Christ, Ramsey said.

There's been some confirmation of drug use, and possibly what they're calling "methamphetamine psychosis". There's the report that Nick had attempted suicide a few days before the killing, but was not held by county behavioral health because it was drug-related and not mental illness-related. Apparently there's a new statewide policy. A tragedy, perhaps, but it seems the state doesn't have enough money and has been forced by budget cuts to limit all sorts of services.
