We got a 50 page report today from the Oakland Fire Department as to the cause of the fire. It's going to be released to the public soon. It has lots of photos and a ton of info about the electrical situation, the configuration and where everyone was found, and the condition of the area around the victims. The cause cannot be totally determined. But among the possibilities is candles/incense, smoking materials or electrical. No evidence of arson, and natural gas or propane was ruled out.
