It looks like Christopher Dorner killed himself in his showdown with police at a mountain cabin in California. Autopsy results show that Dorner died of a single gunshot wound to the head, reports AP. While he had been in a fierce gunfight with officers prior to that, a spokesman for the San Bernardino Sheriff's Office says the wound appears to be self-inflicted. That gibes with reports from the scene at the time: Police say they heard a single shot as they began pumping in tear gas in the final assault. The spokesman also confirmed that Dorner was hiding for days in a condo near the command center police set up for the manhunt.
The Los Angeles Times, meanwhile, reports that Dorner likely stalked his first victims—Monica Quan and fiance Keith Lawrence—for some time before killing them. A court affidavit says Dorner may have had “journals, maps, photographs and documents containing personal and professional information for Keith Lawrence and the entire Quan family.” Quan's father was the LAPD captain who represented Dorner at a disciplinary hearing that resulted in Dorner's firing in 2007.
