RIVERSIDE (AP) — A fugitive ex-Los Angeles police officer was charged Monday with murdering a Riverside officer in a potential death penalty case, but hundreds of tips triggered by a $1 million reward failed to end the manhunt. Christopher Dorner was also charged with the attempted murder of another Riverside officer and two Los Angeles Police Department officers, Riverside County District Attorney Paul Zellerbach said. The LAPD officers and the Riverside officers were fired on in two separate shootings early Thursday after Dorner, 33, became the target of a manhunt following the killing in Irvine of a former LAPD captain's daughter and her fiance the previous weekend.
