Katherine Harper, a pregnant Texas middle school teacher, has been accused of having an improper relationship with one of her students. The student is only 15 years old, according to multiple reports.

Harper has been arrested and charged for allegedly having a sexual relationship, which lasted a whole summer, with a student. Harper taught English at the middle school and was also a cheerleading coach and a tennis coach.

Eight months pregnant

Katherine Harper has been charged with improper relationship between an educator and student, which is a second-degree felony.

She taught at Tidwell Middle School. The 27-year-old teacher was arrested by the Trophy Club Police Department and taken into Denton County Jail. Fortunately for her, she had enough money to post her $15,000 bond.

The teacher is eight months pregnant. However, it is not clear whether the father of her child is the student she molested. The sexual relationship began when she taught the teenager at Roanoke middle school and lasted the whole summer break.

Sexual encounter involved alcohol

The relationship between Katherine Harper and the student, who is unnamed, began through texting. At first, they allegedly sent one another naked photographs of themselves, along with flirtatious text messages. They eventually engaged in sex at the 15-year-old's home.

Police records show that after the first alleged sexual encounter, which involved alcohol, the pair continued to have sex at his or her home from June 1, 2016, to July 31, 2016.

In December 2016, the investigation was launched by school officials after they received a tip, which was anonymous. A school official interrogated the boy, who allegedly admitted to the relationship and began crying.

The teacher is now on administrative leave but is no longer listed on the school's website.

One of many cases

This incident is one of many, as various female teachers have been charged with similar offenses in the past. One of the more disturbing cases involved 27-year-old Pamela Rogers Turner, who taught physical education, at the Centertown Elementary School.

Over the course of three months, she had a sexual relationship with a 13-year-old student. Even though she was sentenced to eight years in prison, she was released after serving nine months. After her release, she again contacted her victim and sent him explicit messages and photographs, which sent her to prison again.

Haeli Noelle Wey, a math teacher in Austin, Texas, had sexual relationships with two of her students. After being arrested, she had to turn in her teaching certificate and was forbidden from contacting the two victims. Wey was later released on bond and served no prison time.
