SAN FRANCISCO, Aug. 11 (UPI) -- Faulty do-it-yourself wiring in a hot tub was found to be the cause of one of the worst wildfires in California history, fire officials said Wednesday.
After an 11-month investigation, Cal Fire found the faulty wiring of a couple's hot tub in the tiny town of Cobb to be the cause of the 2015 Valley Fire, which scorched 76,000 acres, killed four people, injured four firefighters and destroyed 1,280 homes northeast of San Francisco.
