LOS ANGELES (AP) -- Los Angeles police Chief Charlie Beck says the fugitive ex-police officer wanted in three murders has multiple weapons including an assault rifle.
Beck also says more than 40 protection details have been assigned to possible targets of fired officer Christopher Dorner.
Beck says the massive manhunt for Dorner may be the largest in the department's history.
Dorner is suspected of murdering a couple last weekend, killing one Riverside officer and wounding another early Thursday, and wounding an LAPD officer a short time earlier.
Suspected killer visited San Diego Navy base
The Navy says Dorner stayed on a San Diego base several days ago but a lockdown at the facility has been lifted.
Navy spokesmen say someone reported seeing a man resembling Dorner on Thursday morning at Naval Base Point Loma. The base was sealed and searched for several hours.
Cmdr. Brad Fagan says Dorner checked into a base hotel on Tuesday but left the next day and isn't there now.
Fagan says Dorner, a reserve lieutenant, left the Navy with an honorable discharge on Friday and may still carry military ID.
Here are some key events involving Christopher Dorner, the fired Los Angeles police officer suspected of killing at least three people including a police officer in Southern California and posting a manifesto on Facebook outlining plans to kill the families of those he felt wronged him:
-- Sunday, Feb. 3: Monica Quan, 28, and Keith Lawrence, 27, are found shot to death in their car at an Irvine, Calif. parking structure. Quan, an assistant women's basketball coach at California State University, Fullerton, was the daughter of a former Los Angeles police captain who represented Dorner in disciplinary hearings that resulted in his dismissal.
-- Monday, Feb. 4: Some of Dorner's belongings are found in a trash bin in the San Diego-area community of National City, Calif.
-- Wednesday, Feb. 6: Irvine police announce they are looking for Dorner as a suspect in the killings of Quan and Lawrence. They describe him as armed and dangerous. Police say he implicated himself in the killings in a manifesto posted on Facebook. At about 10:30 p.m., a man matching Dorner's description tries to steal a 47-foot boat from a San Diego marina but the engine won't start. An 81-year-old man on the boat is tied up but not hurt.
-- Thursday, Feb. 7: At around 1:30 a.m. in the Riverside County community of Corona, Calif., two LAPD officers assigned to protect a person named in the manifesto chase a vehicle they believe is Dorner's. During a shootout, one officer is grazed in the forehead. The gunman flees. A short time later, a gunman believed to be Dorner ambushes two Riverside police officers who had stopped at a red light during a routine patrol. One officer is killed and the other critically injured.
-- Around 2:30 a.m., a passer-by finds a wallet with law enforcement badge and a picture ID of Dorner on a street near San Diego International Airport.
-- Three hours later, LAPD officers guarding a manifesto target in the Los Angeles suburb of Torrance, Calif., open fire on a truck they mistakenly believe to be Dorner's. Two women are wounded. A short time later, Torrance police are involved in a second shooting involving a different truck they also mistake for Dorner's. Nobody is hurt.
