It was there that Dorner may have taken refuge last Thursday, four days after beginning a deadly rampage that claimed four lives.
The search ended Tuesday when a man believed to be Dorner bolted from hiding, stole two vehicles, barricaded himself in another vacant cabin miles away and mounted a last stand in the furious shootout in which he killed one sheriff's deputy and wounded another before the building erupted in flames.
He never emerged from the ruins, and hours later a charred body was found in the basement of the burned cabin along with a wallet and personal items, including a California driver's license with the name Christopher Dorner, an official briefed on the investigation told The Associated Press on condition of anonymity because of the ongoing investigation.
The coroner's office is studying the remains to positively determine the identity. It was not clear how the cabin caught fire.
Los Angeles Police Department Lt. Andrew Neiman said Wednesday the agency had returned to normal patrol operations but about a dozen of the more than 50 protective details guarding possible Dorner targets would remain in place until the remains are positively identified.
"This really is not a celebration," he said.
Neiman would not answer any questions regarding what occurred in the mountains of San Bernardino County the previous day, saying it was that jurisdiction's investigation.
LAPD officers used the Internet to monitor radio chatter during the shootout.
"It was horrifying to listen to that firefight and to hear those words. `Officer down' is the most gut-wrenching experience that you can have as a police officer," Neiman said.
Dorner, 33, had said in a lengthy rant that police believe he posted on Facebook last week that he expected to die in one final, violent confrontation with police, and if it was him in the cabin that's what happened.
The apparent end came in the same mountain range where his trail went cold six days earlier, when his burning pickup truck -- with guns and camping gear inside -- was abandoned with a broken axle on a fire road in San Bernardino National Forest near the ski resort town of Big Bear Lake.
His footprints led away from the truck and vanished on frozen soil. Deputies searched door-to-door in the city of Big Bear Lake and then, in a blinding snowstorm, SWAT teams focused on hundreds of vacant cabins in the forest outside of town.
With no sign of him and few leads, police offered a $1 million reward to bring him to justice and end a "reign of terror" that had more than 50 families of targeted Los Angeles police officers under round-the-clock protection after he threatened to bring "warfare" to the LAPD, officers and their kin.
Just a few hours after police announced Tuesday that they had fielded more than 1,000 tips with no sign of Dorner, word came that a man matching his description had tied up two people in a Big Bear Lake cabin, stole their car and fled.
Lt. Patrick Foy with the California Fish and Wildlife Department, which aided the search, said two housekeepers surprised Dorner in the cabin when they came to clean it Tuesday morning. The women were tied up but one was able to free herself and call 911, Foy said.
Fish and Wildlife wardens spotted the Nissan that had been reported stolen going in the opposite direction and gave chase, Foy said. The driver looked like Dorner.
They lost the car after it passed a school bus and turned onto a side road, but two other Fish and Wildlife patrols turned up the road a short time later, and were searching for the car when a white pickup truck sped erratically toward them in the Seven Oaks area, about 30 miles down Highway 38 from Big Bear Lake.
"He took a close look at the driver and realized it was the suspect," Foy said.
Dorner, who allegedly stole the pickup truck at gunpoint after crashing the first car, rolled down a window and opened fire on the wardens, striking their truck more than a dozen times, he said.
One of the wardens shot at the suspect as he rounded a curve in the road. It's unclear if he was hit, but the stolen pickup careened off the road and crashed in a snow bank.
The driver then ran to the cabin where he barricaded himself and got in the shootout with San Bernardino County deputies and other officers, two of whom were shot, one fatally.
A SWAT team surrounded the cabin and used an armored vehicle to break out the cabin windows, said a law enforcement official who requested anonymity because the investigation was ongoing. The officers then lobbed tear gas canisters into the cabin and blasted a message over a loudspeaker: "Surrender or come out."
The armored vehicle then tore down each of the cabin's four walls.
A single shot was heard inside before the cabin was engulfed in flames, the law enforcement official said.
Until Tuesday, authorities weren't sure Dorner was still in Big Bear Lake, where his pickup was found within walking distance from the cabin where he apparently hid.
With many searchers leaving town amid speculation Dorner was long gone, the command center across the street was taken down Monday.
Police said Dorner began his murderous run on Feb. 6 after they connected the Feb. 3 slayings of a former police captain's daughter and her fiance with his angry manifesto.
Dorner blamed former LAPD Capt. Randal Quan for providing poor representation before a police disciplinary board that fired him for filing a false report. Dorner, who is black, claimed in his online rant that he was the subject of racism by the department and was targeted for reporting misconduct by other police.
Dorner vowed to get even with those who had wronged him as part of his plan to reclaim his reputation.
"You're going to see what a whistleblower can do when you take everything from him especially his NAME!!!" the rant said. "You have awoken a sleeping giant."
Within hours of being named as a suspect in the double murder, the 6-foot, 270-pounder described as armed and "extremely dangerous," tried unsuccessfully to steal a boat in San Diego to flee to Mexico. After leaving a trail of evidence, he headed north where he opened fire on two patrol cars in Riverside County, shooting three officers and killing one.
