An Oklahoma teacher was arrested and charged with first-degree rape after allegedly having a threesome with a student and a former teacher, according to reports.

Joyce Churchwell, 40, allegedly sent nude pictures and videos via Snapchat to a teenage student during the 2018-2019 school year. The student then went to Churchwell's home, where they had a threesome with a woman who used to teach in the Berryhill School District. The other woman was not charged.

"He admitted that this encounter had taken place at the teacher’s home along with another adult female—a former teacher at the school district," Casey Roebuck, the communications director for the Tulsa County Sheriff's Office, told News on 6.

The student was 18 at the time of the incident but in Oklahoma, teachers who have sex with students up to the age of 20 are charged with rape. The investigation into Churchwell began after someone informed the school resource officer that something strange was occurring.

The Berryhill School District released the following statement after it discovered the teacher's inappropriate relationship with the student, according to News on 6. She was immediately placed on leave of absence, and the Tulsa County Sheriff's Office believes that other students may have had "inappropriate contact with her."

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 contacted law enforcement about allegations of an inappropriate relationship between a student and a teacher. The district is currently cooperating with law enforcement in the investigation of these allegations and will take appropriate action when the investigation is completed. The teacher has been and is currently on leave of absence. The district will not comment further on this matter because of the ongoing criminal investigation and confidentiality rights of the parties involved.
