Deputy District Attorney Marc Noel said his office is reviewing the report. “Obviously Cal Fire has determined the tree in question started the fire and now it’s our job to find out how and why that tree fell and whether PG&E is criminally at fault,” he said. Noel said Cal Fire’s referral suggests possible violations of law, but he declined to specify any of those findings.
