EX LAPD COP Christopher Dorner

[Duchess]

A person believed to be the fugitive ex-Los Angeles cop sought in three killings exchanged gunfire with authorities in the San Bernardino Mountains on Tuesday, a law enforcement official said on condition of anonymity.

The officer requested anonymity because the officer was not authorized to speak publicly about the ongoing investigation.

It's believed Christopher Dorner committed a residential burglary of a cabin where a couple was tied up, the officer told The Associated Press.

One of the people was able to get away and make a call.

Authorities responded to the location and gave chase when the burglar fled in a stolen car. Gunfire was exchanged.

The area is in the Big Bear region where a search for Dorner has been under way since his pickup truck was found there Thursday.

A KCAL-TV reporter in the Angelus Oaks area along Highway 38 reported gunfire in his vicinity.

The noise of the gunbattle was broadcast by the station, whose reporter suddenly found himself near the fight. Someone could be heard yelling at the reporter to get out of the area.

Road blocks are up around Big Bear.

San Bernardino County sheriff's spokeswoman Jodi Miller said a stolen vehicle report from a residence was received at 12:20 p.m.

"The reporting party identified the suspect as looking like Christopher Dorner but that has not been confirmed," Miller said.
