LA Police chase 600 clues in hunt for ex-cop wanted in murders

Detectives in Los Angeles were following up on some 600 clues to the whereabouts of an ex-police officer suspected of killing three people, a Los Angeles Police Department spokesman said, the day after a $1 million reward was posted for information regarding the fugitive's whereabouts.

Christopher Dorner, 33, has not been spotted since early on Thursday, when he is accused of ambushing two policemen at a red light in Riverside, 60 miles east of Los Angeles. One of those officers was killed, the other wounded.

That confrontation came not long after the former Los Angeles police officer and U.S. Navy veteran is suspected of exchanging gunfire with police in nearby Corona, wounding one officer.

Aside from several false sightings, the search has largely focused on the snow-covered San Bernardino Mountains northeast of Los Angeles, where a truck belonging to Dorner was found burning on a fire road near the ski resort community of Big Bear Lake.

That effort has not been abandoned, LAPD spokesman Lieutenant Andrew Neiman said, but detectives were also busy following up hundreds of clues and tips from the public in hopes that one of them would lead them to the fugitive.

"As of 6 a.m. this morning, our investigators were working on over 600 clues, and I'm sure that number has increased since then," he said.

Dismissing speculation that Dorner's four-day silence may suggest he had taken his own life, Neiman said: "We are operating on the premise that he is still out and about and we are going to find him."

Police officials urged Southern Californians to call a tip line with any information on Dorner's whereabouts, but said that anyone who sees him should call 911 immediately instead.
