Lawyers for former cadets who sued St. John’s Military School over alleged abuse now say the school recently ordered all students to surrender their phones for a review of photos and videos.

Documents filed Monday in federal court claim officials at St. John’s Military School in Salina deleted hundreds of videos and photos from cellphones related to the school.

The court filing says 1 of the videos showed a staff member abusing a student, while some others showed abuse of former cadets who have filed suit.

The school did not immediately respond to emails Monday to it and its attorneys for comment.

The plaintiffs want a judge to forbid the destruction of evidence and to appoint a computer forensics expert at the school’s expense to retrieve deleted material.
