Chris Dorner, the former police officer who sent the LAPD on a massive weeklong manhunt after shooting and killing three people, is apparently engaged in a shootout with authorities Tuesday afternoon.

Dorner, a 33-year-old former LAPD officer and U.S. Navy reservist, is holed up inside a cabin in Angelus Oaks, Calif., in San Bernardino County, and surrounded by law enforcement, according to CBS Los Angeles. There were no indications that he was holding any hostages.

The shootout with a man believed to be Dorner began Tuesday in the Big Bear area after Dorner burglarized a home in the Southern California ski resort town, tied up a couple in the house and stole their pickup truck, a law enforcement source told the Los Angeles Times.

CBS Los Angeles reported two San Bernardino County sheriff's deputies were shot when Dorner exchanged gunfire with authorities; their condition was unclear. You can follow the network's live stream coverage here.

The couple who was tied up said the man who burglarized their home closely resembled Dorner, San Bernardino County sheriff’s spokeswoman Jodi Miller told the Associated Press.

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

The Big Bear area has been under lockdown since Thursday, after Dorner’s burnt-out truck was located there, but he escaped authorities. A manhunt covering much of Southern California was conducted to capture Dorner. Police also considered whether the former cop crossed the border into Mexico.

Dorner is suspected of shooting and killing Monica Quan and her fiancé, Keith Lawrence, in the parking garage of their Irvine, Calif., apartment complex Feb. 3.

Quan is the daughter of former LAPD captain and lawyer Randal Quan, who represented Dorner at the 33-year-old officer’s appeal of his firing from the department.

Dorner is also believed to be responsible for the murder of Riverside Police Department Officer Michael Crain, who was killed Feb. 7 while conducting a routine patrol.

A manifesto published on Dorner’s Facebook page claimed he committed the murders in order to clear his name, referring to his firing.

The former cop was fired after a LAPD board determined he made false statements pertaining to his training officer committing police brutality. Dorner maintained that he was telling the truth.

The city of Los Angeles is offering a $1.1 million reward for information leading to the arrest and conviction of Dorner -- the largest reward in the city's history.
