AUTHORITIES have offered $1m (€748,000) for information leading to the arrest of the former Los Angeles police officer suspected in three killings and the subject of a manhunt in Southern California's snow-covered mountains.
Camping gear was found along with weapons inside the burned-out truck belonging to suspect Christopher Dorner. The truck found on Thursday at Big Bear Mountain, a ski resort 80 miles from Los Angeles, was so charred that investigators couldn't be more specific about its contents, said Los Angeles police Sergeant Rudy Lopez.
Police were also investigating a taunting phone call that may have been made by Dorner to the father of a woman they believe he killed last week.
Dorner (33) has vowed revenge against several former Los Angeles Police Department colleagues whom he blames for ending his career.
On Saturday, Chief Charlie Beck said officials would re-examine the allegations by Dorner, a black former officer, that his law enforcement career was undone by racist colleagues.
While he promised to hear out Dorner if he surrenders, Mr Beck stressed that he was ordering a review of his 2007 case because he takes the allegation of racism in his department seriously.
"I do this not to appease a murderer. I do it to reassure the public that their police department is transparent and fair in all the things we do," he said in a statement.
Authorities suspect Dorner in a series of attacks over the past week that have left three people, including one officer, dead. Authorities say he has vowed revenge against several former colleagues.
The killings and threats that Dorner allegedly made in an online rant have led police to provide protection to 50 families, Mr Beck said.
Meanwhile, the actor Charlie Sheen – described as "awesome" in Dorner's online manifesto – has recorded a personal video message urging Dorner to call him to "figure out" an end to his manhunt.
In his taped message, played on the celebrity website TMZ, Sheen said: "Christopher Dorner, this is Charlie Sheen. You mention me in your manifesto so thank you for your kind words. I'm urging you to call me and let's figure out together how to end this thing Call me. I look forward to talking to you."
