RIVERSIDE, Calif. (KABC) -- A former Los Angeles police officer wanted in connection with a double murder in Irvine is being sought in the shootings of three officers Thursday. Two officers were shot in Riverside and the other was shot in Corona.
The Riverside Police Department says one of its officers was killed. The other Riverside officer was undergoing surgery, and his condition was not immediately known.
The officer shot in Corona is with the Los Angeles Police Department. He suffered a non-life threatening wound. The LAPD says they believe the shooter is suspected gunman Christopher Jordan Dorner, a former LAPD officer wanted in connection to the double-murder of a couple in Irvine.
Authorities say Dorner wrote a multi-page manifesto in which he threatened to kill law enforcement officials and implicated himself in the Irvine murders.
According to the LAPD, two of its officers were in Corona Thursday morning to check on one of the individuals named in Dorner's manifesto when they came across a pickup truck that matched Dorner's. The officers ran the license plate and found that it did not match the vehicle. They started to follow the truck when the gunman opened fire with a shoulder-weapon, like a rifle, officials said. One officer was grazed in the head, but is expected to be OK. The officers were in a marked police vehicle and in uniform.
Riverside investigators were also looking into the possibility that their shooting suspect is Dorner. They said the two officers were on routine patrol around 1:35 a.m. when they stopped at a red light at Magnolia and Arlington avenues and were ambushed by a gunman in a gray pickup truck.
Dorner's whereabouts were unknown. Authorities say Dorner may be driving a 2005 charcoal gray Nissan Titan pickup truck. They believe he changed his license plate from 7X03191 to 8D83987 following the Inland Empire police officer shootings.
The suspect is considered armed and extremely dangerous. A blue alert has been activated in the following counties: Kern, Santa Barbara, Ventura, Los Angeles, San Bernardino, Orange, Riverside, San Diego, and Imperial.
Dorner, 33, is described as an African-American man standing 6 feet tall, weighing 270 pounds. He has black hair and brown eyes. If seen, call 911.
Dorner named suspect in Irvine double-murder
Keith Lawrence, 27, and his fiancée Monica Quan, 28, were found fatally shot in a car in the parking lot of their apartment complex in Irvine Sunday. Irvine Police identified the suspect as Dorner, a former LAPD officer and Navy reservist.
Authorities said Dorner appears to have murdered Quan in an act of revenge against her father, Randy Quan, a former LAPD officer who retired and became an attorney.
Court documents obtained by Eyewitness News show that in August 2007, Dorner made a complaint against his field training officer accusing her of kicking a suspect. However, the LAPD Board of Rights found Dorner's complaint to be false and terminated his employment for making a false statement. The attorney representing Dorner was Randy Quan.
Dorner threatens LAPD officers in manifesto
In a manifesto obtained by Eyewitness News, Dorner says he has other targets, including commanding officers within the LAPD. In response, the LAPD deployed its elite Metropolitan Division officers to protect certain personnel and their families.
"I will bring unconventional and asymmetrical warfare to those in LAPD uniform whether on or off duty," the manifesto says.
"You may have the resources and manpower but you are reactive and predictable ... I have the strength and benefits of being unpredictable, unconventional, and unforgiving," it goes on to say. Dorner also threatens to kill any officer who attempts to arrest him.
Dorner also provides a glimpse into why he may have acted out: "I've lost a relationship with my mother and sister because of the LAPD. I've lost a relationship with close friends because of the LAPD. In essence, I've lost everything because the LAPD took my name and new (sic) I was INNOCENT!!!"
In a statement, the LAPD said, "The Department has learned that Christopher Dorner has made threats against members of the LAPD and we are taking those threats very seriously as we do all threats against our personnel and the public."
For their safety, motorcycle officers not are not being deployed and patrols will be done in two-officer units.
The LAPD confirmed that Dorner worked as one of its police officers from February 2002 to September 2008 and that his employment was terminated.
Heavy police presence in Torrance
Meantime, there was an officer-involved shooting in Torrance Thursday morning. Police say two civilians were shot and injured on Redbeam Avenue. The LAPD says its officers were at the site in connection with the Dorner investigation and the Inland Empire police officer shootings, but they did not give further details. A bullet-riddled blue pickup truck with newspapers on the ground on the passenger's side of the truck was parked at the scene.
About two blocks away, authorities were also investigating another incident in which a black Honda pickup truck appeared to have been involved in a crash with a Torrance police vehicle. There appeared to be three bullet holes in the windshield. It was unclear if or how that was related to the Dorner case.
