Police said a suspected robber was shot and killed with his own gun in the city's West End.
Police identified the man as Charles Long, 32, of McKees Rocks.
Investigators said Long kicked open the door of a house along Parson Street in Esplen just after 2:30 a.m. Sunday.
Terrence Triplett, 27, was inside and managed to wrestle Long's gun away and shot him twice, police said.
Officials said when they arrived, they found Long lying just inside the doorway.
No charges have been filed against Triplett at this time.
