Electrical lines and towers are seen on Tuesday along North Altadena Drive to the northwest of where the fire may have been sparked. The Bureau of Alcohol, Tobacco, Firearms and Explosives has now taken the investigative lead in the Palisades Fire. One possible theory that has neither been substantiated nor ruled out as of Monday, according to officials, is the involvement of transmission lines or electric facilities in inciting any of the LA County fires.
