At 3:55 am on December 9, 1981, in Philadelphia, close to the intersection at 13th and Locust streets, Philadelphia Police Department officer Daniel Faulkner conducted a traffic stop on a vehicle belonging to and driven by William Cook, Abu-Jamal's younger brother. Faulkner and Cook became engaged in a physical confrontation.[30] Driving his cab in the vicinity, Abu-Jamal observed the altercation, parked, and ran across the street toward Cook's car.[4] Faulkner was shot in the back and face. He shot Abu-Jamal in the stomach. Faulkner died at the scene from the gunshot to his head.
Police arrived and arrested Abu-Jamal, who was found to be wearing a shoulder holster. His revolver, which had five spent cartridges, was beside him. He was taken directly from the scene of the shooting to Thomas Jefferson University Hospital, where he received treatment for his wound.[31] He was next taken to Police Headquarters, where he was charged and held for trial in the first-degree murder of Officer Faulkner.[32]
