LOS ANGELES, CA (CBS) -- The frantic search for a former LAPD police officer accused of murdering three people is now centered on a ski resort town about 80 miles east of Los Angeles.
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. San Bernardino County Sheriff John McMahon says, "We are assuming he is still in the area because we are continuing to look."
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. He wrote: "The violence of action will be high. I will bring unconventional and asymmetrical warfare to those in LAPD uniform whether on or off duty. You will now live the life of the prey."
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. Sergio Diaz, Chief of Police Riverside, says, "This is a somewhat unprecedented or at least a very rare occurrence for us where you have a trained and heavily armed person who is, who is hunting for police officers."
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.
