A ‘concerning’ message found in Jim Thorpe’s Penn Kidder Campus led to a three-hour lockdown on Thursday.

School officials said the ‘non-critical lockdown’ was put in place to allow Kidder Township Police and school officials to investigate, not because there was any threat of an intruder.

During the lockdown, no one was allowed in or out of the school building. Students stayed in the same classroom throughout the day, with bathroom breaks. Lunch was served in the rooms.

“It’s a lockdown but we continue on with classes, not like we’re barricaded in a room,” Rushefski said.

The message was discovered around 11 a.m. School officials checked lockers and found no items that led them to believe the threat was real.

“There was nothing connected that we would be concerned about,” Rushefski said. “That’s when we lifted the non-critical lockdown.

Rushefski declined to say the specific nature of the threat. He said investigation was continuing into who made it.
