SACRAMENTO, Calif. (AP) – Several insurance companies have filed lawsuits blaming Pacific Gas & Electric Co., for the deadly Camp Fire that destroyed 14,000 homes and triggered billions of dollars in insurance claims. The lawsuits filed by Allstate, State Farm and USAA come on top of several other cases filed by victims of the Camp Fire, which devastated the towns of Paradise, Magalia and Concow north of Sacramento. Investigators have not pinpointed a cause for the fires but the insurance companies note in their lawsuits that the fire began near the site of a transmission line irregularity reported by the utility. A PG&E spokeswoman says the company is focused on assessing infrastructure and helping customers recover. The lawsuits were filed last month in Sacramento County Superior Court.
