SPRING BRANCH, Texas – A former Spring Branch ISD teacher who molested a student is not getting off as easily as she originally thought.

Back in December, Kathryn Murray, 31, was charged with one count of having an improper relationship with a student and one charge of sexual assault of a child for her sexual exploitation of a 15-year-old student.

Last month, she was sentenced to two years probation with one year served in jail. But that sentence was set aside because the judge by law could not sentence her to probation for the sexual assault of a child charge, reports Click2Houston.

Her new sentence, agreed upon by both lawyers, requires Murray to spend two years in prison with no probation.

The relationship between the teacher and the student began at Memorial Middle School where the teen, originally from Costa Rica, was trying to learn English with help from his tutor, Kathryn Murray.

Murray began keeping the student after school and would pass him notes that spoke of the perfect life they could have together, the story reports.

According to investigators, the two began a sexual relationship in her classroom on February 7, 2012.

Court records indicted there were several sexual encounters, including one at the boy’s home while his parents weren’t there. On another instance, Murray picked up the eighth-grader at a school dance and took him to a hotel where they had sex.

The encounters came to an end when the student’s younger brother caught the pair in bed. The brother reported to his parents that he found a condom and a bra in the bedroom.

This led to Murray’s initial arrest and she was shortly released on $50,000 bond.

While she was free on bond, she was once again arrested after the teen ran away from home and was found with Murray.

The teacher was charged with harboring a runaway but the charge was dropped as part of an accepted plea bargain.

Even with the sentence extended, the boy’s mother, Jenny Pallais, believes that the punishment does not fit the crime.

Pallais claims that Murray took advantage of a young boy who was in a new country and didn’t understand the language or the culture.

“This was not justice,” she said. “This was a child who believed and trusted in his teacher.”

Once Murray is released from prison, she will be required to register as a sex offender for life.
