On February 3, 2013, a series of shootings began in Orange, Los Angeles and Riverside counties in California, United States, in which the victims were law enforcement officers, their families, and civilians misidentified as the suspect. Christopher Dorner, 33, an involuntarily terminated Los Angeles police officer, was named as a suspect wanted in connection with the series of shootings that killed four people and wounded three others. The rampage ended on February 12, 2013, when Dorner died during a standoff with police at a cabin in the San Bernardino Mountains.
A manifesto posted on Facebook, which police say was written by Dorner, declared "unconventional and asymmetric warfare" upon the Los Angeles Police Department (LAPD), their families, and their associates, unless the LAPD admitted publicly he was fired in retaliation for reporting excessive force.
In two separate incidents during the manhunt, police shot at three civilians unrelated to Dorner, mistaking their pickup trucks for the vehicle being driven by Dorner. One of the civilians was hit by the police gunfire, another was wounded by shattered glass, and a third individual was injured when police rammed his vehicle and opened fire.
