Police say Dorner killed a Los Angeles police captain's daughter and her fiance Sunday in a parking garage in Irving, Calif., and then used a rifle to ambush two police officers in Riverside on Thursday, killing one and seriously wounding the other. Dorner is also suspected of shooting and wounding a third police officer in Corona.
Dorner fulfilled his lifelong dream of becoming a Los Angeles police officer in 2005, but saw it unravel three years later when he was fired after a police review board decided he falsely accused his training officer of kicking a mentally ill man in the face and chest.
The incident led Dorner to plot violent revenge against those he thought responsible for his downfall, according to a 14-page manifesto police believe he authored because there are details in it only he would know.
