KENNEBUNK, Maine (NECN) — New information surfaced Thursday about the criminal case against former Kennebunk High School health teacher Jill Lamontagne.

The 29-year-old was indicted by a York County grand jury on 14 counts of sexual abuse charges relating to an alleged affair with a 17-year-old student.

According to Kennebunk Police Chief Bob MacKenzie, the department first heard of the allegations in April, but could not corroborate the alleged victim's story.

The student's mother filed a protection order against Lamontagne last summer, alleging that the student had attempted suicide and told hospital staff and his aunt that he was upset about a sexual relationship with his teacher.

According to court documents, the student said that he had sexual encounters with his former teacher in the classroom, at her home, and in a car.

"We could not corroborate it at that time, but since then, we had additional information that came forward, and we re-opened the case," MacKenzie said.

Lamontagne's attorney, Scott Gardner, called the allegations nothing more than a "rumor" based on the "sexual fantasies of a 17-year-old."

"These charges will be fought tooth and nail, because they're false," Gardner said.

Lamontagne posted $1,000 bail and is scheduled to be arraigned in December.

"She's a dedicated teacher, and she's absolutely devastated by this whole situation," Gardner said.
