The fired ex-California cop who set off a region-wide manhunt after allegedly shooting three police officers this morning -- one fatally -- had initially gone to a yacht club near San Diego where police say he attempted to steal a boat and flee to Mexico. Police say that former police officer Christopher Jordan Dorner, 33, who officials believe posted an online manifesto outlining his plan to "terminate" his former colleagues and their families, is armed with a long gun and might have several other guns and high-capacity magazines. He is also believed to have access to military uniforms because he has served in the Navy. "We are considering him armed and dangerous," Lt. Julia Engen of the Irvine Police Department said. Police allege that he went to the yacht club Wednesday night at Point Loma, Calif., near San Diego to steal the boat. He aborted the attempted theft when the boat's propeller became entangled in a rope, law enforcement officials said. It was at that point he is believed to have headed to Riverside, where he allegedly shot two police officers. "He pointed a handgun at the victim [at the yacht club] and demanded the boat," Lt. David Rohowits of the San Diego Police Department said. Police say the rifle marksman shot at four officers in two incidents overnight, hitting three of them: one in Corona, Calif., and the two in Riverside, Calif. Sgt. Rudy Lopez of the LAPD said two LAPD officers were in Corona and headed out on special detail to check on one of the individuals named in Dorner's manifesto. Dorner allegedly grazed one of them but missed the other. "[This is an] extremely tense situation," Lopez said. "We call this a manhunt. We approach it cautiously because of the propensity of what has already happened." The Riverside Police Department said two of its officers were shot before one of them died, KABC-TV reported. The other is in stable condition with two gunshot wounds, police say. "They were on routine patrol stopped at a stop light when they were ambushed," Lt. Guy Toussant of the Riverside police department said. In the manifesto Dorner published online, he threatened at least 12 people by name, along with their families. "Your lack of ethics and conspiring to wrong a just individual are over. Suppressing the truth will leave to deadly consequences for you and your family," Dorner wrote in his manifesto. A badge and identification belonging to Dorner have been found in San Diego, according to San Diego police Sgt. Ray Battrick. Dorner's LAPD badge and ID were found by someone near the city's airport, and turned in to police overnight, The Associated Press reported. Police around Southern California are wearing tactical gear, including helmets and guns across their chests. The light-up signs along California highways show the license plate number of Dorner's car, and say to call 911 if it is seen. The problem, police say, is that they believe Dorner is switching license plates on his car, a 2005 charcoal-gray Nissan Titan pickup truck. Los Angeles Police Department Chief Charlie Beck said today that 40 protective details have been deployed to protect officers and their families.
"We are taking all measures possible to ensure safety of our officers and their families," he said.
