Police fired in two separate incidents at vehicles similar to the one sought, and struck two people, none of whom were the suspect, Christopher Jordan Dorner, the Los Angeles Times reported.

A LAPD spokesman told the newspaper that it was not immediately clear if the vehicles' occupants matched Dorner's physical description. The two shooting victims were transported to an area hospital, with unknown injuries. Dorner, 33 -- who is described as a 6-foot-tall African-American weighing about 270 pounds -- remains at-large. He has black hair and brown eyes, police said. His last known address was in La Palma.

Dorner is accused of shooting two Riverside Police Department officers early Thursday morning, while they were on a routine patrol near Magnolia and Arlington streets. An LAPD officer suffered a graze to the head in Corona, 50 miles east of Los Angeles, around 1:30 a.m. while protecting one of the intended targets in Dorner's manifesto, the New York Daily News said. Police said they are guarding about 40 people Dorner mentions in his rant.

He was believed to be driving a black Nissan Titan pickup truck, California license plate 8D83987 or 7X09131. He may have changed the plates to elude authorities, they said.

In addition to the shootout with police, Dorner is also accused in the deaths of a couple found shot in the parking lot of their upscale apartment complex in Irvine on Sunday night. The victims have been identified as Cal State Fullerton assistant basketball coach, Monica Quan, 28, the daughter of a former LAPD officer, and her fiancé, Keith Lawrence, 27.
