The massive manhunt continues Friday across Southern California for Christopher Dorner, a former LAPD officer on a self-confessed vendetta.
Dorner has already left three people dead (including one police officer) another person seriously wounded and some strange shout-outs to celebrities.
San Bernadino County Sheriffs confirmed in a news conference that cabins are being scoured in the snowy mountains surrounding Big Bear, Calif.
Dorner, a former LAPD officer with military training, has a cabin there.
Police earlier found Dorner's burned-out pickup truck and tracks leading away from the vehicle off a wooded road near Big Bear, officials say.
Authorities say that he has made clear that his alleged wave of violence is retribution for having been fired in 2008 after making false statements.
Christopher Dorner has even said he would stop the killing when and if the LAPD publicly proclaimed his innocence and restored his reputation.
"The department has not changed since the Rampart and Rodney King days. It has gotten worse," he wrote in a document that he called his "Manifesto."
He continued: "I know I will be vilified by the LAPD and the media."
"Unfortunately, this is a necessary evil that I do not enjoy but must partake and complete for substantial change to occur within the LAPD and reclaim my name."
Police departments throughout the Los Angeles area continue to help try and capture Dorner, who is said to be armed with assault rifles and other weapons.
Dorner's alleged victims are said to be two Riverside, Calif., police officers, ages 35 and 27, who were parked in their squad car. The elder officer died.
In addition, Monica Quan and her fiancé, Keith Lawrence, were found shot to death in their car Sunday, according to Irvine Police Chief David L. Maggard.
