Kellyville High School Teacher Arrested For Sex With Student

A Kellyville English teacher has been arrested for second degree rape in connection to an alleged inappropriate relationship with a high school student that is said to have been going on for months.

Creek County Detectives said it may have started through text messages back in December, and as it turns out, detectives said pictures taken from a cell phone are what exposed the relationship.

Kalyn Darby Thompson, 25, hadn't even been teaching for a full year when she resigned from her position at Kellyville High School in April, an arrest report states. She turned herself into authorities Monday morning.

"This will follow her for the rest of her career," said Creek County Detective Chrissie Underwood. "She probably will not have a career in teaching after this."

Underwood said she met with Kellyville administrators who told her Thompson was involved with an 18-year-old student. The high school principal said the teacher and student had been exchanging texts "of a sexual nature."

Underwood said Thompson started texting with her student when he was 17.

"There was talk about getting high, grades, that sort of things," Underwood said.

The student's mother also reportedly told investigators the teen admitted to having sex with his teacher at Heyburn Lake in Creek County and again at the Renaissance Hotel in Tulsa.

"She [Thompson] was asked not to contact him, not to have any contact with him outside of school, and she still did," said Underwood.

By the time the student was 18, Underwood said the relationship escalated. She said two Kellyville students saw Thompson sitting in the teenager's truck off campus, took some pictures and tipped off school leaders.

"Which is mandatory in their position, they have to contact us, so they did everything they were supposed to do," Underwood said.

Underwood said because a teacher is in a position of power, it doesn't matter if a teenager is of consenting age, it's still illegal for a teacher to sleep with a student.

"It's sad because they're vulnerable to it and obviously he's getting a good grade from it," said Underwood.

Detectives also recovered text messages between the two on their phones. Police say some of those messages were sexual in nature while others mention "getting high" and school grades.

The arrest report states that the student was flunking English last semester but currently has a 98 percent grade point average.

Thompson is charged with one count of 2nd Degree Rape.

She turned herself in Monday morning and was released on bond shortly after being booked into the Creek County jail.

Detectives said a second charge is likely.
