A state fire investigation’s conclusion that Pacific Gas & Electric Corp. equipment was not to blame for a deadly wildfire in Northern California wine country could complicate the utility’s plans to file for bankruptcy. It could also hamper lawsuits by victims of the blaze. State investigators said Thursday the 2017 blaze that killed 22 people and destroyed more than 5,600 structures in Sonoma and Napa counties was caused by a private electrical system.
