A Los Angeles County Sheriff's Department helicopter becomes airborne to resume the search for fugitive Christopher Dorner Saturday Feb. 9, 2013 near Big Bear, Calif. The aerial search was suspended Friday due to heavy snowfall. More than 100 law enforcement officers, some in armored personnel carriers, hunted Saturday for the former Los Angeles police officer suspected of going on a deadly rampage this week to get back at those he blamed for ending his police career.

(AP) - The hunt for a former Los Angeles police officer suspected in three killings continued in snow-covered mountains Saturday as the LAPD's chief said he would reopen the disciplinary case that led to the fugitive's firing and new details emerged of the evidence he left behind. Officials will re-examine the allegations by Christopher Dorner, 33, that his law enforcement career was undone by racist colleagues, Police Chief Charlie Beck said. While he promised to hear out Dorner if he surrenders, 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," the chief said in a statement. Authorities suspect Dorner in a series of attacks in Southern California over the past week that left three people dead, including a police officer. Authorities say he has vowed revenge against several former LAPD colleagues whom he blames for ending his career. The killings and threats that Dorner allegedly made in an online rant have led police to provide protection to 50 families, Beck said. A captain who was named a target in the manifesto posted on Facebook told the Orange County Register he has not stepped outside his house since he learned of the threat, and he was taking it seriously. "From what I've seen of (Dorner's) actions, he feels he can make allegations for injustice and justify killing people and that's not reasonable," said Capt. Phil Tingirides, who chaired a board that stripped Dorner of his badge. The end never justifies the means. Saturday was the third full day of a massive multi-agency hunt for Dorner in the San Bernardino mountains, about 80 miles northeast of downtown Los Angeles, where Dorner's burned-out pickup truck was discovered Thursday. A scaled-back search party took advantage of a break from stormy weather to search for Dorner using heat-sensing helicopters as vacationing families and weekend skiers frolicked nearby. A law enforcement officer told The Associated Press authorities found weapons in the truck. The officer spoke on condition of anonymity because the probe is ongoing. Investigators have been examining the truck to determine if it broke down or was set ablaze as a diversion. Police say the truck had a broken axle. Investigators are trying to determine whether it was already broken when they found it, or whether it was damaged when it was towed away. Newly released surveillance video showed Dorner tossing several items into a Dumpster behind an auto parts store in National City on Monday. The store's manager told FOX5 in San Diego that an employee found a magazine full of bullets, a military belt and a military helmet. Majid Yahyai said he and the employee took the items across the street to a police station. In his online manifesto, Dorner vowed to use "every bit of small arms training, demolition, ordnance and survival training I've been given" to bring "warfare" to the LAPD and its families. Dorner served in the Navy, earning a rifle marksman ribbon and a pistol expert medal. The flight training that he received in the Navy prompted the Transportation Security Administration to issue an alert on Friday, warning the general aviation community to be on the lookout for Dorner. The extent of his potential flying skills wasn't known, the bulletin said. On Feb. 3, police say Dorner shot and killed a couple in a parking garage at their condominium in Irvine. The crime spree spanned across a wide swath of Southern California, prompting several police agencies, including the FBI and US Marshall Service, to form a joint investigative task force on Saturday.
