A loaded handgun was found at William T. Dwyer High School Friday afternoon during dismissal.
The gun was found on a cabinet. A student saw the gun and notified administrators.
School police are investigating who owns the gun and why it was brought into the building.
Dwyer Principal Joe DePasquale sent a recorded phone call to all parents notifying them of the incident.
The message says that whoever brought the weapon onto campus could face criminal charges and school disciplinary action.
This comes nearly two weeks after an 18-year-old student is accused of bringing a 12-inch knife to school and threatening a class mate.
She was arrested.
One Dwyer High School parent says she is not stressed about the situation, but does hope to learn who the gun belongs to.
Others are concerned about hearing of two weapons in the school in less than a month.
“There’s only so much you can do," one mother said, about security at the school. "Whoever's gun this was, they'll investigate. They'll find out."
