Christopher Jordan Dorner (June 4, 1979 – February 12, 2013) was a former Los Angeles Police Department (LAPD) officer and U.S. Navy Reserve lieutenant who, beginning February 3, 2013, carried out a series of shootings targeting LAPD personnel and their associates across Orange, Los Angeles, Riverside, and San Bernardino counties, California. Dorner had been fired by the LAPD in 2008 after an internal review found he had made false statements in a report alleging that his training officer, Teresa Evans, used excessive force against a man with schizophrenia. Dorner's appeals of his termination were rejected by the Los Angeles County Superior Court and, in 2011, by the California Court of Appeal.
In early February 2013, Dorner posted an approximately 11,000-word manifesto on Facebook listing law enforcement personnel he intended to kill and demanding that the LAPD publicly acknowledge his termination was retaliatory. He had also sent a package to CNN journalist Anderson Cooper containing a DVD outlining his grievances against the department.
On February 3, 2013, Monica Quan, a 28-year-old assistant basketball coach and daughter of Randal Quan (the retired LAPD captain who had represented Dorner at his 2008 dismissal hearing), and her fiancé Keith Lawrence, 27, a USC campus safety officer, were shot dead in a parked car in Irvine. On February 7, Dorner shot two LAPD officers near Corona, grazing one; approximately twenty minutes later he ambushed two Riverside police officers stopped at a traffic light, killing officer Michael Crain and wounding the other. Dorner's burned vehicle was later found near Big Bear Lake, and he is believed to have occupied a cabin in the area for several days.
That same night, LAPD officers on a protection detail in Torrance mistakenly fired on a vehicle driven by Emma Hernandez and her daughter Margie Carranza, who were delivering newspapers and were unrelated to Dorner; both women were wounded but survived. A separate Torrance Police Department shooting minutes later struck an unrelated vehicle driven by David Perdue, who was not hit by gunfire but was injured when a police cruiser collided with his truck. Neither shooting resulted in criminal charges, though the LAPD later disciplined eight officers for use-of-force policy violations, and settlements were paid to the victims.
On February 12, 2013, after carjacking a couple's truck near Big Bear Lake, Dorner exchanged gunfire with San Bernardino County Sheriff's deputies, killing Detective Jeremiah MacKay and wounding another deputy, before barricading himself in a nearby cabin. Following a standoff involving tear gas and a demolition vehicle, the cabin caught fire; a single gunshot was heard from inside before the blaze consumed the structure. On February 14, medical examiners confirmed via dental records that human remains found in the cabin were Dorner's, and an autopsy later determined he died of a self-inflicted gunshot wound to the head.
