California police say they believe former Los Angeles police officer Christopher Dorner has died in a final standoff in the snowy mountains of Big Bear. A suspect believed to be Dorner took refuge in a cabin after a car chase with police on Tuesday, leading to a shootout. A single gunshot was reportedly heard from within the cabin before it erupted in flames. Officers are now testing the dead body recovered from the site to confirm they have found Dorner’s remains. San Bernardino County Sheriff’s spokesperson Cindy Bachman said a sheriff’s deputy was killed in the gunfight between Dorner and police, bringing his victim toll to four.

Cindy Bachman: “The suspect that was driving the vehicle abandoned the vehicle and fled on foot into the forest. He barricaded himself in a cabin. At that time, there was an exchange of gunfire between the law enforcement personnel outside of the cabin and the subject inside. During that gunfight, a deputy sheriff — two deputy sheriffs were shot. One of them died after being taken to Loma Linda. The second deputy is currently in surgery and is expected to survive.”

Dorner’s apparent death would end a manhunt that began after he vowed to exact revenge on the LAPD for his firing in 2008.
