LOS ANGELES (Reuters) – State fire investigators have determined that transmission lines owned 2018 Pacific Gas & Electric Co caused the deadliest and most destructive wildfire on record in California, a blaze that killed 85 people last year, officials said on Wednesday.

Shares of San Francisco-based PG&E fell 3.1 percent in after-hours trading following release of the California Department of Forestry and Fire Protection (Cal Fire) statement announcing findings of its investigation of the November 2018 Camp Fire in Northern California.
