Three officers were shot -- two in Riverside, one in Corona -- during the search early Thursday for a former Los Angeles Police Department officer wanted in connection with a double slaying in Irvine.

Police said two Riverside officers responded to Magnolia and Arlington avenues (map) at about 1:30 a.m. after receiving a call for assistance. The response occurred during a search that began with a report of a vehicle matching the description of ex-LAPD Officer Christopher Dorner.

"By all accounts, it appears they were stopped at a red light and just

ambushed by the suspect," said Riverside Lt. Guy Toussaint.

Both Riverside officers were shot and transported to a hospital, where one was pronounced dead. The second officer remained in surgery, police said.

"The suspect did flee the scene, and we're in the process of trying to identify and apprehend the suspect at this time," said Toussaint.

The LAPD confirmed officers are looking for Dorner in connection with the Riverside shooting.

Corona Sgt. Brent Nelson confirmed that the Riverside shooting is connected to another Thursday morning shooting in Corona. LAPD's Newton Division confirmed early Thursday that two of its officers were involved in a confrontation with a man believed to be Dorner.

One of the officer's was shot, suffering what was described as a "minor" graze wound.

Irvine police revealed Wednesday that a former LAPD officer is suspected of killing an Irvine couple. Christopher Jordan Dorner is apparently targeting LAPD personell who were involved in his termination from the force, and their families.

Officers in protective gear were at the locations in Corona and Riverside.

A third officer-involved shooting was reported at about 5:30 a.m. in Torrance. Officers did not confirm that shooting was connected to the Dorner search.

Also early Thursday, the San Diego Harbor Police Department confirmed a badge with Dorner's picture identification was found at about 2:27 a.m. in the center divider on Harbor Drive, near San Diego International Airport.

"Multi-Page Manifesto" Implicated Ex-LAPD Officer

Dorner is wanted in connection with the double slaying of a newly engaged couple last weekend, Irvine Police Chief David Maggard said Wednesday evening. Maggard said that Dorner implicated himself in a "multi-page manifesto" that was published online but has since been taken down. A source inside LAPD gave NBC4 the manifesto, which is about 11,300 words long and appears to lay out a plan for targeting those involved in his firing.

In the manifesto -- addressed to "America" and titled "Last Resort" -- Dorner writes that the "horrendous murders" are "a necessary evil."

"I know I will be villified (sic) by the LAPD and the media," he writes. "Unfortunately, this is a necessary evil that I do not enjoy but must partake and complete for substantial change to occur within the LAPD and reclaim my name."

Dorner goes on to say, "There will be an element of surprise where you work, live, eat, and sleep."

Monica Quan, 28, and her fiancé, Keith Lawrence, 27, were fatally shot Sunday while sitting in their car on the top level of a parking structure in the 2100 block of Scholarship Drive, according to Irvine police. The recently engaged couple was last seen in Winnetka at a Super Bowl party, and lived in the apartment complex attached to the parking garage. The couple left the party about 7 p.m. and were found slumped over in their car about 9 p.m.

Quan's father was the first Asian-American to become an LAPD captain, and also worked on the Asian Gang Task Force.

In his manifesto, Dorner repeatedly refers to a Randy Quan as being involved in his firing.

Authorities asked for the public's help in finding Dorner, whose last known address is 4931 Sharon Dr. in La Palma. Dorner is described as 6 feet tall, about 270 pounds with black hair and brown eyes.
