Station fire was set intentionally

 LOS ANGELES (AP) - Investigators launched a homicide investigation Thursday into the wildfire north of Los Angeles after determining that the gigantic blaze - which has killed two firefighters, scorched 226 square miles and destroyed dozens of homes - was set intentionally.
"We believe that this was caused by someone intending to set a fire," sheriff's spokesman Steve Whitmore said at an afternoon briefing.
Officials said forensic evidence at the fire's point of origin revealed that the wildfire - among the largest in Southern California's history - was an act of arson. Whitmore declined to elaborate on the evidence due to the ongoing investigation.
