Fire investigators believe the fire north of Los Angeles that threatened Mt. Wilson broadcast and communications towers as well as an historic observatory was deliberately set. Two firefighters died fighting the so-called Station fire on Mt. Wilson in what is now a homicide investigation, authorities say.
The Associated Press reports investigators found evidence leading them to believe that arson is responsible for the blaze that has killed two firefighters and charred more than 147 acres of the Angeles National Forest.
Incendiary material was found along Angeles Crest Highway, the Los Angeles Times reported on Friday.
Many of the evacuated residents from the area are now able to return to their homes and broadcast engineers have begun returning to check on their facilities. No serious damage to broadcast stations has been reported.
