Disgruntled former LAPD officer Christopher Dorner is believed barricaded in a mountain cabin after wounding two deputies during a gun battle this afternoon, according to the San Bernardino County sheriff's office.
Authorities have the cabin surrounded near Big Bear Lake, which is about 100 miles northeast of Los Angeles. Dozens of SWAT officers and armored vehicles have been sent to the scene.
"Enough is enough. It is time to turn yourself in," said an unidentified police commander. "It is time to end the bloodshed."
A police source told the the L.A. Times that the shooting occurred after Dorner burglarized a home, tied up a couple and stole their car. A spokeswoman with the San Bernardino sheriff's office said the two wounded deputies were transported from the area via air ambulance. Their conditions were not immediately known.
"Suspect is pinned down next to the shooting scene," a San Bernardino dispatcher said over a police radio channel. "Marshals have a positive ID and visual of the suspect."
A 3-mile-wide perimeter has been set up by police, and authorities were asking news helicopters not to broadcast live video of the cabin.
"We don't want to tip our hand," a police commander said.
Residents in the area were being told to stay inside and lock their doors. The California Highway Patrol has closed all highways near the scene.
"People should stay away from that area. It is not safe right now," a police spokeswoman told KTLA-TV.
Dorner has been on the run for seven days. He is accused of killing three people--including one police officer--last week.
The 33-year-old former naval and LAPD officer turned triple-murder suspect, has been at the center of a massive manhunt stretching from the Bernardino Mountains—where his burned-out pickup truck was found last week—to the Mexican border.
In a manifesto posted online earlier this month, Dorner promised "unconventional and asymmetrical warfare" against the LAPD, which fired him in 2008. On Saturday, actor Charlie Sheen—who was mentioned in Dorner's online manifesto—released a video pleading with the accused killer to call him.
On Saturday, police conducted a door-to-door search for Dorner in Big Bear Lake, Calif., but snowfall hampered their efforts in the surrounding mountains.
On Sunday in Los Angeles, an increased police presence was seen at the Grammy Awards, which some thought Dorner might target. In Northridge, Calif., a home improvement store was evacuated after a report of a possible Dorner sighting, hours after the LAPD announced a $1 million reward for information leading to his arrest.
"This is the largest local reward ever offered, to our knowledge," Los Angeles Police Chief Charlie Beck said at a news conference. "This is an act of domestic terrorism. This is a man who has targeted those that we entrust to protect the public. His actions cannot go unanswered."
