A person confirmed to be former LAPD cop, fugitive and alleged murderer Christopher Dorner exchanged gunfire with police today, officials say.
A law enforcement source says Dorner fired on authorities in the San Bernardino Mountains after he burglarized a cabin and had a couple tied up in there.
One was able to get away and make a call. Authorities responded to the location and gave chase mid-day Tuesday when Dorner fled in a stolen car.
At that point, gunfire was exchanged. A second source said there was an active crime scene; it is not immediately clear whether Dorner is in custody.
UPDATE, 5:35 p.m. EST: Authorities believe Dorner is barricaded in a cabin in the mountains. Vehicles leaving the area are being searched at gunpoint.
UPDATE, 6:30 p.m. EST: Cops believe they are poised to get their man and that they "have him cornered." A perimeter has been established by cops.
UPDATE, 7:15 p.m. EST: Dorner is using smoke grenades to fend off police, and two officers have reportedly been shot; one is believed to be dead.
UPDATE, 8:00 p.m. EST: The cabin is on fire, according to TMZ. A person on the scene says it's "completely engulfed in flames." It's unclear if Dorner is still inside.
UPDATE, 9:30 p.m. EST: The cabin has burned to the ground. Police are surrounding the property and waiting to move in to search for any sign of Dorner.
UPDATE, 2/13: It will take awhile to make a positive ID but remains are among the ashes and police are all but certain they will find Chris Dorner dead.
Story developing ...
It's the latest and possibly final chapter of the massive Dorner manhunt.
Law enforcement officials are swarming the area, not long after U.S. Marshal's officials said in court papers that Dorner could have fled to Mexico.
In Tijuana, Dorner was listed as one of the most wanted fugitives. But the LAPD later said that was only one of many locations authorities were scouring.
Detectives have also been examining video showing Dorner purchasing scuba gear in Torrance, Calif., days before his alleged killing spree began.
Officers have been all over California pursuing tips about Dorner's possible whereabouts, serving warrants at homes in Las Vegas and Point Loma.
Meanwhile, an associate of Dorner was being tracked by investigators, suggesting that he may have received help eluding a massive law enforcement dragnet.
Dorner, 33, has evaded authorities since Wednesday when he was named the suspect in the slaying of an Irvine couple. He also allegedly killed a cop.
There is a $1 million reward for Dorner's capture.
