CHICAGO (CBS) — Police are investigating a teacher at Downers Grove North High School, after a 1999 graduate accused the teacher of sexually harassing her.

Jennifer Boudinot says she is coming forward to expose the alleged sexual misconduct of a long-term teacher at the high school. She said her initial Facebook post about the teacher caused additional former students to come forward with their stories of inappropriate comments and acts — dating back almost 20 years.

“There’s no shame in this. This teacher should feel ashamed, but I’m not going to feel ashamed, I don’t want my friends to feel ashamed. And if that means that I have to go and be the public face of this for them, I’m happy to do it,” Boudinot said.

“He used to go into online chat rooms with me and a friend of mine and just kind of talk about adult things,” she added.

In a statement, District 99 Superintendent Dr. Hank Thiele said that administrators recently began looking into the allegations:

“It was brought to our attention recently that conversations on social media pointed to potentially inappropriate behavior on the part of a current teacher at North High. In response, we immediately began gathering facts surrounding the concerns, and placed the teacher on administrative leave.”

Furthermore, the statement said the District has long-standing policies and procedures to investigate any report that is brought forward; however, they are unable to comment publicly on any personnel matters.

Boudinot says she talked with police, and hopes others will now do the same.

Theresa Kulat, a Downers Grove North parent, said the investigation is the right step. “I think it’s good that they’re doing an investigation and I hope that, whatever happens, that everyone is taken care of — whether it’s the student, the teacher, the community.”

The Downers Grove Police Department is conducting the investigation. A spokesperson for the department says the investigation began last week and is still in the early stages. No indication on if any charges are forthcoming.
