The district says a staff member found it when the student went through the school’s metal detector.

A report was submitted to Childline, the district says, and parents will receive a notification about the incident.

KDKA spoke with a grandparent who is now thankful for the security.

“It can be hectic because they want to take their time and make sure they get each child and go through their things to make sure,” Lydia Wade said. “So good thing they do that.”

Wade was picking up her granddaughter early from school Friday when she got a letter about the incident that was sent by the principal.

The letter, in part, says:

“The safety of our students and staff is always a top priority. … We take this issue very seriously.”

School representatives say the child came late to school and did not ride the bus with the gun.

While how the student got their hands on the gun remains unknown, the school is encouraging parents to have the talk about gun safety with their kids.

The incident is under investigation by the Pittsburgh Public School Police.
