Officer Michael Daniel Crain, 34, of the Riverside Police Department was ambushed and fatally shot on February 7, 2013. He and his partner were stopped at a red light at Magnolia Avenue and Arlington Avenue about 1:30 am when Christopher Dorner, a former LAPD officer, opened fire on their patrol car. Crain was killed and his partner was severely wounded.

Dorner had been dismissed from the LAPD in 2008 and, according to his online manifesto, admitted to prior killings and stated he intended vengeance on those involved in his dismissal. The shooting of Officer Crain occurred amid a wider series of attacks that prompted a large manhunt; Dorner was later found in a Big Bear cabin and died after a standoff with law enforcement.

Crain had 11 years of service with Riverside PD and was a U.S. Marine Corps veteran. His death prompted memorials and tributes and prompted reviews of the circumstances surrounding Dorner’s actions.
