Justin Adrian, 34, was found guilty of aggravated battery and sexual battery in Johnson County District Court.
According to court documents Adrian, a social studies teacher and head of the school’s Gay-Straight LGBTQ Club, communicated with the student over Grindr, an online dating app.
Adrian sent a number of sexually explicit messages and told the student, who was over 18 at the time, that he could lose his job if others knew they were talking. He also asked the student to meet him in his classroom.
When the student came to his classroom, according to court documents, Adrian sexually assaulted the student for several minutes.
He then allegedly wrote the student a pass for being late to his next class.
According to the lawsuit the assault left the student “horrified, scared and in shock.”
He told his family and a friend about the assault and went to the hospital for a sexual assault exam, according to the lawsuit. A family member reported the incident to school officials.
Adrian was placed on administrative leave from the district after the incident was reported last September and later resigned from the Shawnee City Council.
Adrian is scheduled to be sentenced on Jan. 8.
