The Daily Breeze in Torrance also reports (http://bit.ly/YWhBLi) that there was another police shooting nearby involving another pickup truck, but the driver wasn't hurt.
"We're asking our officers to be extraordinarily cautious just as we're asking the public to be extraordinarily cautious with this guy. He's already demonstrated he has a propensity for shooting innocent people," said LAPD Cmdr. Andrew Smith.
Dorner is wanted in the killings of Monica Quan and her fiance, Keith Lawrence. They were found shot in their car at a parking structure at their condominium on Sunday night in Irvine, authorities said.
Quan, 28, was an assistant women's basketball coach at Cal State Fullerton. Lawrence, 27, was a public safety officer at the University of Southern California. There was disbelief at three college campuses, Fullerton, USC, and Concordia University, where the two met when they were both students and basketball players.
Dorner was with the department from 2005 until 2008, when he was fired for making false statements.
Quan's father, a former LAPD captain who became a lawyer in retirement, represented Dorner in front of the Board of Rights, a tribunal that ruled against Dorner at the time of his dismissal, LAPD Capt. William Hayes told The Associated Press Wednesday night.
Randal Quan retired in 2002. He later served as chief of police at Cal Poly Pomona before he started practicing law.
According to documents from a court of appeals hearing in October 2011, Dorner was fired from the LAPD after he made a complaint against his field training officer, Sgt. Teresa Evans. Dorner said that in the course of an arrest, Evans kicked suspect Christopher Gettler, a schizophrenic with severe dementia.
Richard Gettler, the schizophrenic man's father, gave testimony that supported Dorner's claim. After his son was returned on July 28, 2007, Richard Gettler asked "if he had been in a fight because his face was puffy" and his son responded that he was kicked twice in the chest by a police officer.
Early Thursday, the first shooting occurred in Corona and involved two LAPD officers working a security detail, LAPD Sgt. Alex Baez. One officer was grazed.
Later, two officers on routine patrol in neighboring Riverside were ambushed at a stop light, said Riverside Lt. Guy Toussaint. One died and the other was in surgery. The officers shot were not actively looking for Dorner, Toussaint said.
Dorner's LAPD badge and an ID were found near San Diego's airport and were turned in to police at early Thursday, San Diego police Sgt. Ray Battrick said.
