A house party on the 1000 block of Crawford Avenue in Duquesne, Pennsylvania, ended in violence in the early hours of Monday, November 3, 2025. First responders arrived shortly after 12:45 a.m. to find 32-year-old Shawn O’Leary inside the home with multiple gunshot wounds; he was pronounced dead at the scene.

Originally from Dravosburg, O’Leary’s family and neighbors remembered him as kind, generous and hardworking — a loyal friend and a caring son who was trying to build a stable life. Neighbors said the typically family-friendly neighborhood was left on edge. The Allegheny County Police Department’s Homicide Unit is investigating; preliminary findings indicate an argument at the party may have escalated to the shooting. No suspects or arrests have been announced.

Anyone with information about the November 3 shooting is asked to contact the County Police Tip Line; those who knew Shawn or were at the party are urged to come forward.
