A Montgomery County Public Schools special education teacher used social media to cultivate a relationship with a student he ultimately allegedly sexually abused, according to court documents.

Magruder High School teacher Peter Wright Priest Mason, 42, allegedly exchanged Snapchat names with an underage victim on the last day of the 2018-19 school year.

According to court documents, Mason and the victim regularly communicated over the summer, and then into the ensuing school year.


Mason allegedly told the victim – who was a student in his class – that he was “interested in her.” He then had sexual contact with the victim in a park near the school, where they met several other times.

Court documents indicate that Mason also had sexual contact with the victim in his classroom.

Police were tipped off to Mason’s alleged crimes when he told a family member about his relationship with the underage girl.

On Wednesday, Mason was arrested and charged with sexual abuse of a minor and fourth-degree sex offense by a person in a position of authority.

Magruder Principal Leroy Evans sent a letter to parents Tuesday saying the school district is fully cooperating with law enforcement. Evans says Mason has been placed on administrative leave.

Mason has been employed with MCPS since 2011. The letter says "he worked as a paraeducator at Northwest High School from 2011 to 2015 and has worked as a special education teacher at Magruder High School since 2015."
