The investigation started in May 2023. The former choir teacher was accused of inappropriate touching and comments made to girls.

At the time, Pius XI administration sent out a letter to parents. It notified them of the investigation – and that the long-term substitute, Anshus, was put on a leave of absence. During the investigation, court filings said Anshus was fired. 

In February 2024, detectives learned new information, alleging that Anshus sexually assaulted a student.
