BIG BEAR LAKE, Calif. — After a shootout and a forest standoff on Tuesday afternoon, Christopher J. Dorner, the former Los Angeles police officer sought in the region’s largest manhunt, was apparently killed in a cabin as it burned down around him, but officials said they needed time to sort through the rubble.
At 11 p.m., the San Bernardino County Sheriff’s Office released a statement, saying that “charred human remains” had been located inside the burned-out cabin. Though the remains were not identified as those of Mr. Dorner — “identification will be attempted through forensic means,” the statement said — there is little doubt they are his.
“We believe he was still inside the cabin” when it went up in flames, Cindy Bachman, a spokeswoman for the sheriff’s office, said earlier during a news conference in Angelus Oaks, six miles from the scene. Mr. Dorner, a self-described survivalist believed to be heavily armed, had holed up in the rental cabin hours earlier and engaged deputies in a shootout, killing one deputy and wounding a second.
The dramatic chain of events, which included hostage taking and a chase in vehicles and on foot, played out in the sun-dappled, snowy San Bernardino Mountains.
It was unclear how the fire at the cabin began, but the authorities said that no one escaped the blaze and that Mr. Dorner was believed to be alone inside.
Officers, shouting orders through loudspeakers for Mr. Dorner to surrender, heard what they believed to be a single gunshot from within.
News organization widely reported that Mr. Dorner’s body was found in the building, but a spokesman from the Los Angeles Police Department said on Tuesday evening that they did not have the body.
Even after officers retrieve the body, it could take days or weeks to identify it, officials said. Cindy Bachman, a spokeswoman for the San Bernardino County sheriff, said in an evening news conference, “We believe that he was still inside the cabin,” but that it was not safe to enter because of the heat.
Both the suspect and the police were believed to have used smoke grenades during the shootout. The two deputies who were shot were airlifted to Loma Linda University Medical Center; the second deputy’s condition was not disclosed on Tuesday evening, but he was expected to recover.
The standoff drew scores of police officers and sheriff’s deputies from surrounding jurisdictions, led by the San Bernardino Sheriff-Coroner Department. The tension heightened as the day wore on, and local schools were locked down.
Law enforcement agencies ordered news helicopters to keep their distance for the protection of the officers involved. The sheriff’s online feed to the department’s radio scanner was shut down for the same reason. Reporters were asked to stop posting updates on Twitter.
The police believed that Mr. Dorner was monitoring the news, and Cmdr. Andrew Smith, a spokesman for the Los Angeles Police Department, addressed him directly at a news briefing on Tuesday afternoon.
“Enough is enough,” Commander Smith said. “It’s time to stop the bloodshed and let this incident be over.”
Officers had been searching the Big Bear area since last week, when Mr. Dorner’s burning truck was found on a forest road. Mr. Dorner, a former reservist in the Navy, had boasted about his sharpshooting and survival abilities.
Days ago, Mr. Dorner apparently broke into a couple’s home on Club View Drive, the authorities said on Tuesday. The street is nestled beside a golf course in a community called Moonridge near Big Bear Lake. Mr. Dorner reportedly tied them up as his hostages and stayed out of sight until Tuesday afternoon.
Shortly after 12 p.m. Tuesday, the authorities received a report of a stolen white pickup truck and a description that fit Mr. Dorner’s. Soon after, he was spotted driving a white 2005 Dodge pickup by an officer with the California Department of Fish and Wildlife. The suspect was driving toward the officer in the opposite lane, said Andrew Hughan, a spokesman for the department. The officer recognized Mr. Dorner, stepped out of his vehicle and fired at the suspect, who returned fire. Neither was injured, Mr. Hughan said.
The officer and a colleague chased the man, who crashed the pickup, fired at them and ran into the cabin.
