Fired teacher pleads not guilty to having sex with student

A former math teacher at Pacelli Catholic high school in Austin is pleading not guilty to charges that she had sex with a 17-year-old male student.

Mary Gilles, 28, faces six counts of third-degree criminal sexual conduct for allegedly having sex several times with a 17-year-old male student over the past eight months. She entered a not guilty plea in Mower County District Court Monday morning, the Austin Daily Herald reports.

According to the criminal complaint, a staff member at the school became concerned when earlier this month she saw Gilles and the victim alone together in the school auditorium late at night.

An administrator searched the student’s email accounts and found numerous messages between the student and Gilles that indicated they were in a sexual relationship. The emails also revealed that Gilles could be pregnant by the student.

Police reviewed the emails and arrested Gilles at her home on Oct. 6. She was suspended from her job then, and fired a day later.

The victim and Gilles admitted to police that they have been sexually involved since February, according to the complaint.

Gilles' next court appearance is April 10. She is free on bond, according to the Daily Herald.

In addition, the school fired two of its top administrators last week for undisclosed reasons. Its president, James Hamburge, and elementary principal Mary Holtorf had been placed on leave just after Gilles was arrested, but the school gave no other information about the circumstances that led to the decision.
