UPDATE: 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.

From CBS Los Angeles:

As of present time — according to the above live feed — more cops have been shot and/or killed:

The cabin quadruple-murder suspect Christopher Dorner is believed to be holed up in is now fully engulfed in flames, according to KCAL9′s Carter Evans.

LAPD Cmdr. Andy Smith Tuesday urged Dorner to turn himself in as a gun battle and barricade situation raged on in San Bernardino County.

“Enough is enough. It’s time to turn yourself in. End the bloodshed,” Smith said, adding that Dorner, who allegedly shot and killed his fourth victim — a San Bernardino County Sheriff’s deputy — Tuesday afternoon, is holed up in a Seven Oaks cabin.

Dormer is also accused of shooting a second deputy, who was airlifted to Loma Linda University Medical Center. Smith, who says Dorner likely has access to television and other media outlets, requested that media helicopters pull out of the area.

The San Bernardino District Attorney’s Office also asked that reporters in the area to refrain from tweeting about the ongoing situation.

Dorner reportedly broke into a couple’s home and tied them up — possibly days ago — before stealing their vehicle and fleeing the scene Tuesday afternoon.

He was spotted by authorities around 1:30 p.m. and repeated gunshots were exchanged on Glass Road. KCAL9′s Carter Evans, who was reporting nearby, is safe despite loud gunfire that could be heard during his live report.

Dorner then fled into a forested area and barricaded himself in a cabin. A SWAT team was also called in to set up a perimeter around the area.
