Massive manhunt under way for ex-cop accused of killing 3

LOS ANGELES (AP) — Thousands of police officers throughout Southern California and Nevada hunted today for a former Los Angeles officer who was angry over his firing and began a deadly shooting rampage that he warned in an online posting would target those on the force who wronged him, authorities said.

Authorities 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.

Dorner has available multiple weapons including an assault rifle, said police Chief Charlie Beck.

More than 40 protection details were assigned to possible targets of Dorner. The manhunt was possibly the largest in department history, Beck said.
