Los Angeles-- California authorities filed formal charges Monday against former Los Angeles police officer Christopher Dorner for the murder of a police officer and the attempted murder of three other officers.
Dorner was charged with first-degree murder in the ambush of Riverside Officer Michael Crain, Riverside District Attorney Paul Zellerbach announced at a news conference. The charge carries two "special circumstances," which would make Dorner eligible for the death penalty if caught and convicted.
Dorner was also charged with three counts of attempted murder in the wounding of Crain's partner and two others in separate shootings.
Zellerbach said the three officers were not being identified out of concern for the safety of their families.
Zellerbach reiterated the $1 million reward for information leading to the arrest of Dorner and again asked for the public's help in catching him.
Dorner was named last week as the primary suspect in the Feb. 3 shooting deaths of Monica Quan, 28, and her fiancé, Keith Lawrence, 27. In an online manifesto, Dorner cites Quan's father as being involved in his 2008 firing from the Los Angeles Police Department. Dorner alleged that he was dismissed for reporting that his training officer used excessive force.
