Enhanced security measures coming to Pius XI Catholic High School after graffiti threat

MILWAUKEE (CBS 58) -- Administrators at Pius XI Catholic High School are preparing for students to return to class in person on Tuesday, Nov. 12, one week and a day after a graffiti threat led to online classes. 

In a letter to parents and guardians, school principal Ryan Krienke said that the "inexcusable threats and destruction of property" at the school took place around 12:50 a.m. on Monday, Nov. 4. Security video at the school recorded a person with an orange ski mask and a gray hoodie painting a threatening message on the front of the building. 

When students make their way into school, they will now go through metal detectors. Armed security will be on school grounds and there will be adjustments made to specific locations for drop-off, pick-up and after school activities. 

"I think parents and students are going to appreciate it, even though it is an inconvenience," Krienke said. “If we thought there were compromises in this plan, we wouldn’t be back tomorrow.”

While speaking to reporters on Monday, Krienke said the school had received three threats over the course of four weeks at the school, the most significant threat on Nov. 4. 

No arrests have been made yet. Police thoroughly searched the building last week.
