“The familiar protocol requires students to turn off and put away their cell phones. The new addition involves passing through metal detectors provided by a community partner,” said Ryan Krienke, Principal, Pius XI Catholic High School.

If the metal detector goes off, students receive a secondary screening with a handheld metal detection wand. Female students will be checked by female guards.

Principal Krienke acknowledges while the process may feel overwhelming, safety remains the highest priority.

“This is the third threat incident, and this one was larger and more direct. We decided to close the school temporarily to allow the police investigation to continue,” said Krienke.

The school has also increased the number of security guards patrolling inside and around the building.

“We have students who have children of their own here, and I have kids too. Every decision was made in the students’ best interest,” said Krienke.

After a series of threats, leaders at Pius Catholic High School are taking no chances, saying the safety and security of the entire school community is always top priority.
