It was nearly 10 p.m. in Wilkinsburg, Pa. when two young men approached a home on Montier Street and knocked on the door.
The homeowner, upon seeing the two late-night visitors, retrieved a handgun from the bedroom and returned to the front door. The owner opened the door to hear his guests out and was greeted by the barrel of a shotgun. He opened fire first, striking the shotgun wielder and sending the accomplice fleeing down an embankment.
The wounded intruder was taken to the hospital and his friend turned himself into police not long after.
