A high school teacher in Oklahoma was arrested for allegedly having a threesome in her home with a student and a former teacher in the district, a report said.

Joyce Churchwell, a volleyball coach at Berryhill High School in Tulsa, connected with the teen via Snapchat and invited him over to her home last school year, according to News on 6, citing the local sheriff’s office.

The student “admitted that this encounter had taken place at the teacher’s home along with another adult female — a former teacher at the district,” Casey Roebuck, a spokeswoman for the Tulsa County Sheriff’s Office, told the station.

Churchwell turned herself in Tuesday after authorities issued a warrant for her arrest, the report said. She was charged with rape.

Authorities believe there may be more victims. Amid the investigation, they discovered Churchwell had messaged another student, who didn’t comply.

Churchwell was placed on a leave of absence, the school said in a statement.

“The Berryhill School District takes the safety of its students very seriously and does everything it can to provide a safe learning environment.

“The district is currently cooperating with law enforcement in the investigation of these allegations and will take appropriate action when the investigation is completed.”
