Baldwin Borough police Chief Michael Scott discussed Monday night what may have happened during the friendly fire that wounded one of his officers over the weekend.
Allegheny County police are investigating, and Baldwin police will determine whether officers followed procedure while responding to a domestic dispute early Sunday morning.
Sgt. Ralph Miller, who was shot in the back, was in stable condition Monday at UPMC Mercy, Chief Scott said. He has served on the force for 14 years, where he works as the traffic officer.
Chief Scott said the man inside the home in the 5100 block of Elmwood Drive started to close the door when officers asked to see what was in his hand, which was not visible.
A Baldwin officer put his foot in the door, and Sgt. Miller pushed his shoulder against the door, attempting to open it. The officer's gun went off, hitting Sgt. Miller between his protective vest and his belt.
Chief Scott said the first officer's patrol rifle is the police equalivant to an AR-15 military rifle.
