An ex-Northwest school district English teacher accused of having sex with a student while she was pregnant was sentenced to 10 years probation and six years in prison on Thursday, according to an official with the Denton County District Attorney’s Office.
Katherine Ruth Harper, 28, was accused of having sex multiple times with a 15-year-old male student last summer at her Fort Worth home and at his home in Trophy Club, according to an arrest warrant affidavit.
Harper pleaded guilty to one count of sexual assault of a child and one count of having an improper relationship with a student, said Jamie Beck, Denton County first assistant criminal district attorney.
Harper will first serve the prison sentence and then be placed on probation. Once Harper completes probation she will be required to register as a sex offender for the remainder of her life, Beck said.
