KENNEBUNK, Maine (NEWS CENTER) — A former Kennebunk High School teacher is facing several charges in connection with a sexual assault case being investigated by police.

Jill M. Lamontagne of Kennebunk turned herself in Wednesday, police said. The 29-year-old had recently been indicted by the York County Grand Jury on a total of 14 counts.

Kennebunk police said the indictment came after an investigation, which concluded that the former teacher was allegedly involved in a relationship with a male student under the age of 18 while she was a teacher at the school.

The Associated Press reports RSU 21 Superintendent Katie Hawes announced in June that Lamontagne was being placed on leave during an investigation.

Lamontagne was charged with six counts of gross sexual contact, six counts of sexual abuse of a minor and two counts of unlawful sexual contact.

She was booked and released after making $1,000 bail and is due in court Dec. 22.

Lamontagne's lawyer provided NEWS CENTER with the following statement:

"Mrs. Lamontagne categorically denies the charges. These allegations arise from a high school rumor which consisted of the fantasies of an emotionally troubled senior at Kennebunk High School. None of this is true. Mrs. Lamontagne will enter pleas of not guilty to all charges."
