A jury in Outagamie County has convicted a former Little Chute teacher of Repeated Sexual Assault of the Same Child.

The jury returned a guilty verdict Friday in the trial of Jason Lavigne, 46. The trial lasted three days in Outagamie County.

Investigators say the case dates back to 1999 when Lavigne sexually assaulted one of his students who was a 14-year-old freshman at the time.

A criminal complaint says the victim sent an email to a school counselor in 2009 to report details of incidents that happened between January 1999 and late March 1999.

The superintendent did not report the girl's claims to police. He said he didn't find enough evidence that Lavigne acted inappropriately.

Fox Valley Metro Police were tipped off about the case from Marinette County investigators who had obtained Lavigne's personnel file. Lavinge is charged in Marinette County with 3rd Degree Sexual Assault.

The Marinette County case involves the alleged assault of a 16-year-old girl during a trip to Lavigne's family cabin in Stephenson.

The Little Chute School District placed Lavigne on administrative leave after charges were filed in the Marinette County case.

Lavigne violated conditions of his bond in Marinette County after defying a judge's order that he have no contact with minors. He posted bond again and was arrested for the Outagamie County case a few days later.

Lavigne is scheduled to stand trial in Marinette County on May 22.

He'll be sentenced in the Outagamie County case on June 24.
