William O'Shaughnessy

Sergeant O'Shaughnessy was shot and killed when he was alerted to the robbery of a speakeasy on Lenox Avenue in Harlem. As he approached the scene, he opened fire on the two suspects, who returned fire, killing him.

The two men then stole a taxi cab and fled until they crashed a short time later. Four nearby policemen heard the crash and went to investigate, not knowing of the earlier shooting. The two men opened fire on the four officers, who immediately returned fire. The two men were taken into custody. Both were convicted of Sergeant O'Shaughnessy's murder and executed in the electric chair on December 10, 1932.

Sergeant O'Shaughnessy was assigned to the 28th Precinct.
