Update 7:39 a.m. Police confirm that a body has been found in the burned cabin, but are waiting for forensic confirmation that is indeed Dorner. 

Original: A new sighting of fugitive ex-cop Chris Dorner along California's highway 38 in Big Bear, California stirred police into action early Tuesday. The Los Angeles Times reports that a suspect resembling Chris Dorner broke into a house, tied up a couple and stole their white pickup truck stolen around 12:20 p.m. local time. The Times and AP reported that Dorner engaged in a shootout with fish and game officials some time after that and fled to a cabin in the woods. A stretch of the highway was now closed while authorities continue searching for Dorner. Two officers were hit in the fire fight, one of them fatally, and it was quiet for a few minutes. Witnesses report hearing a single gunshot, after which the cabin went up in flames. It's unclear if Dorner shot himself or escaped before the fire, but police say they didn't see the fugitive emerge from the cabin before the gunshot or the fire. (Update, 9:46 p.m.: Authorities found a body they believe to be Dorner inside the burned-out cabin after the flames calmed down. Update, 10:21 p.m.: Sources inside the L.A. mayor's office confirmed that the body was Dorner's, as have multiple law enforcement sources. Law enforcement officials have yet to confirm that Dorner is dead. Update, 11:16 p.m.: In a press conference, LAPD commander Andy Smith said that, in fact, no body had been found inside of the cabin, despite earlier reports that it has. Smith added that the cabin was "still too hot and no inspectors had access to it yet." Dorner remains at large.)
