(CBS/AP) - Los Angeles police have a message for fugitive ex-LAPD officer Christopher Dorner, believed to be barricaded in a cabin surrounded by law enforcement officers in Big Bear, Calif.: "Enough is enough...it's time to stop the bloodshed."

Those words were directed at Dorner Tuesday afternoon by LAPD Cmdr. Andrew Smith after a gunman believed to be Dorner traded perhaps hundreds of rounds with officers in the San Bernardino Mountains.

Two officers were said to be wounded in the gunfire exchange. It's not clear which agency the two wounded agents belong to, State Fish and Wildlife Assistant Chief Dan Sforza told CBS Los Angeles.

Dorner is wanted for three murders. Sunday, Feb. 3, assistant Cal State Fullerton women's college basketball coach Monica Quan, 28, and her fiance, Keith Lawrence, 27, were found shot to death in their car in Irvine, Calif. Police learn later that Quan was the daughter of a retired Los Angeles police captain who represented Dorner in disciplinary hearings that resulted in his dismissal from the force.

On Thursday, Feb. 7, a shooter believed to be Dorner ambushed two Riverside police officers during a routine patrol. Officer Michael Crain was killed, and the other officer critically injured.

Deputies searching for Christopher Dorner in the Big Bear area responded to a report of a stolen vehicle in the area about 12:20 p.m.

The people whose vehicle was stolen described the suspect as looking very similar to Dorner.

Police located the vehicle, and the suspect ran into the forest and barricaded himself inside a cabin. A short time later there was an exchange of gunfire between law enforcement and the suspect.

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, Feb. 7. The shootout occurred in Seven Oaks off Highway 38, about five miles as the crow flies from where Dorner's pickup was found.

He said he would get even with those who wronged him in an event to reclaim his good name.

Chief Charlie Beck, who initially dismissed the allegations in Dorner's rant, said he would reopen the investigation into his firing - not to appease the ex-officer, but to restore confidence in the black community, which long had a fractured relationship with police that has improved in recent years.
