A fugitive ex-Los Angeles police officer with a $1m (€750,000) reward on his head has been charged with murdering a police officer and special circumstances that could bring the death penalty.
Riverside County District Attorney Paul Zellerbach said Christopher Dorner (pictured) was also charged with the attempted murder of another officer in Riverside, about 90km east of LA, as well as two police officers in Los Angeles.
The LAPD officers and the two Riverside officers were fired on in two separate shootings early last Thursday after Dorner became the target of a manhunt suspected of killing a former LAPD captain's daughter and her fiance the previous weekend.
"By both his words and conduct, he has made very clear to us that every law enforcement officer in Southern California is in danger of being shot and killed," Mr Zellerbach said.
Along with responding to routine calls, police had been protecting dozens of families considered possible targets.
