Daniel J. Faulkner (December 21, 1955 – December 9, 1981) was an American police officer in the city of Philadelphia who was shot and killed in the line of duty. Mumia Abu-Jamal was convicted of first-degree murder for the shooting and sentenced to death (his sentence has since been commuted to life imprisonment without parole after many years of appeals). Faulkner's murder was the culmination of a traffic stop in downtown Philadelphia, not initially involving Abu-Jamal, which escalated into an exchange of gunfire in which Abu-Jamal was himself shot and wounded by Officer Faulkner. Since 2000, the City of Philadelphia has memorialized Faulkner with a street designation and a commemorative plaque.
