Three people were killed in Philadelphia, including a suspected robber gunned down by an off-duty police officer, and three others were wounded in overnight violence this weekend.

At about 1:50 a.m. Sunday, a Philadelphia police officer, going home after working a late shift in the 19th District, was confronted by two men after exiting his personal car in the 5800 block of Webster Street in the Cobbs Creek section of West Philadelphia, police said.

According to police, the two men announced a robbery and one of them put a gun to the officer's chest. The officer then shot one of the robbers with his off-duty handgun. The other robber fired at least one shot at the officer while fleeing on foot.
