(CNN) -- Three females and a male shooter were killed Friday in central Pennsylvania, authorities said.
Three Pennsylvania State Police officers were hurt while responding, according to Blair County District Attorney Richard Consiglio. One of them was wounded when a bullet hit his armored vest, another was hurt in a vehicle accident involving the unidentified shooter, and the third was hit by flying glass as the shooter fired through the windshield of the officer's vehicle.
Blair County Coroner Patty Ross said that three females and one male, the shooter, were dead. It was not immediately clear whether all four fatalities were from gunshot wounds or where they were killed.
