A body believed to be that of renegade ex-Los Angeles police officer Christopher Jordan Dorner was found Tuesday in a burning cabin near Big Bear Lake, California, multiple law enforcement sources told CNN.

The sources told CNN contributor and former FBI assistant director Tom Fuentes that law enforcement removed the body and are conducting a forensic exam to positively identify the man.

The law enforcement sources said they were told by officials at the Los Angeles Police Department that it is Dorner's body.

The fire began after a SWAT team stormed a cabin near Big Bear Lake where a suspect -- who authorities said matched Dorner's description -- had holed up after a fatal shootout with San Bernadino County sheriff's deputies, a source familiar with the operation told CNN.

The cabin caught fire after police detonated smoke devices inside the cabin, the source said.

Aerial images showed heavy smoke and flames coming from a structure. The cabin continued to burn for hours after the fire started.

One of the two sheriff's deputies wounded earlier Tuesday in the shootout earlier with the suspect died, San Bernardino County Sheriff John McMahon told reporters at California's Loma Linda University Medical Center. The other deputy was in surgery "but he should be fine," McMahon said.

The wounded officers were taken to the Loma Linda facility after shots were exchanged with a man at a police roadblock near Big Bear Lake, the sheriff's office said earlier in a statement.

The day's confrontations began when a California Fish and Wildlife officer was driving down a highway near Big Bear and he recognized a man fitting the description of Dorner -- target of a massive manhunt since last week -- driving a vehicle in the other direction. The wildlife officer chased the vehicle and the driver opened fire on the officer before abandoning the truck, a statement from the agency said.

The officer's vehicle was hit numerous times, the statement said. While not specifically referring to the officer involved in the shootout, the statement said the agency's officers "are all safe and accounted for."

Cindy Bachman, a spokeswoman for the San Bernardino Sheriff's Department, said the suspect fled into the woods then into the cabin where he fired at the approaching deputies and holed up though the afternoon, still exchanging gunfire with authorities.

Later as the fire burned, with authorities staying back, she said authorities weren't 100% sure the suspect was still in the cabin.

Authorities have been searching for Dorner since he was named as the suspect in the shooting deaths February 3 of the daughter of his police union representative and her fiance. Police also say he killed one officer in Riverside, California, and wounded two others last Thursday.

The violent spree, authorities say, was part of Dorner's campaign of vigilante justice for what he believes was his unfair termination.

Los Angeles police spokesman Lt. Andy Neiman said Tuesday that the department had received more than 1,000 tips on Dorner's whereabouts. Some of the calls have come from Dorner's acquaintances or people who think they have spotted the fugitive.

The pace of tips being given to investigators increased by 400% after the city of Los Angeles put up a $1 million reward on Sunday for information leading to Dorner's arrest and conviction, Neiman said.

The search for the 270-pound, 6-foot Dorner has focused on the Big Bear Lake area, where authorities say his burning truck was discovered last week.

Over the past two weeks, the search, considered one of the largest in the history of Southern California, has taken authorities from Orange County to the border of Mexico and from Los Angeles to Big Bear Lake.

"Big Bear's still where we're looking right now," Neiman said Tuesday. The search area surrounds where Dorner's burning truck was discovered last Thursday .

"Until we can confirm that he's either there or he's not there, this investigation has to stick with what we know and what we know is that we found evidence that he was there," Neiman said.
