Suicide cause of Tassajara Fire

So, this is it, he commits suicide by self immolating himself with the intent to die in one of the most painful suicide methods imaginable. Ok, the residents are going to need the answers from the investigators when they finally decide to get around to answering more specific questions. I hope they won't mind too terribly being SPECIFIC about what led them to these conclusions. Looking forward to it. When it comes down to brass tacks, I wonder if fire officials and law enforcement officials are in agreement to the same scenario.
