Pennsylvania State Police are investigating an incident Tuesday in which a school van was struck with a bullet in Armstrong County.
A substitute driver was heading along Route 422 in Plumcreek shortly after 6 a.m. when she heard a "loud noise," and pulled over, thinking something might have fallen off the Dodge Caravan, said Trooper Thomas Karlo in the Kittanning barracks.
The driver was just beginning her route and no students were on the bus. She saw a bullet hole in the rear driver's side panel, and a mechanic found a bullet fragment, the trooper said.
"We don't know if was accidental or intentional," he said.
He added that the driver didn't believe anyone would have been targeting her. Tuesday marked her first day as a sub on that route, which likely was serving a school in the Armstrong School District. he said.
