LOS ANGELES – Thousands of police officers throughout Southern California and neighboring states hunted Thursday for a disgruntled former Los Angeles officer wanted for going on a deadly shooting rampage that he warned in an online posting would target those on the force who wronged him, authorities said.

Police issued a statewide “officer safety warning” and police were sent to protect people named in the posting that was believed to be written by the fired officer, Christopher Dorner, who has military training. Among those mentioned were members of the Los Angeles Police Department.

“I will bring unconventional and asymmetrical warfare to those in LAPD uniform whether on or off duty,” said the manifesto. It also asserted: “Unfortunately, I will not be alive to see my name cleared. That’s what this is about, my name. A man is nothing without his name.”
