Manhunt continues for Ex-LAPD officer - WNCT | 9 On Your Side Greenville NC & Eastern NC News

Police officers kept their rifles ready as they searched door-to-door in the mountain town of Big Bear, California. They are looking for accused cop killer Christopher Dorner. Authorities found his burned-out pickup truck in the town Thursday. They followed fresh foot prints in the snow, but came up empty.

Police are scrambling to find the former LAPD officer and Navy reservist before he can attack again. He is accused of murdering three people including one police officer.

In a rambling manifesto posted on Facebook, Dorner declared war on law enforcement.

Officers are guarding the LAPD headquarters here in downtown Los Angeles and will stay until Dorner is captured or killed. Law enforcement throughout Southern California is on high alert.

The LAPD fired Dorner for making false statements. Police say his first victims were Monica Quan and her fiancé. She is the daughter of the LAPD officer who represented Dorner during his disciplinary hearings. LAPD is now protecting dozens of potential targets named in Dorner's manifesto.

In Torrance Thursday, LAPD mistakenly shot and wounded two people riding in a pickup truck similar to Dorner's.
