Christopher Jordan Dorner (June 4, 1979 – February 12, 2013) was a former LAPD police officer and United States Navy Reserve officer who was charged in connection with a series of shooting attacks on police officers and their families from February 3–12, 2013. The attacks left four people dead, including three police officers, and left three police officers wounded. Dorner was the subject of the largest manhunts in LAPD history, spanning two U.S. states and Mexico.
On February 11, 2013 the Riverside District Attorney filed charges against Dorner for the murder of a police officer and the attempted murder of three other officers. The following day, Dorner died from a self-inflicted gunshot wound to the head, during a stand-off with police at a cabin in the San Bernardino Mountains.
