COLBY, WI (WTAQ) - A teacher in the Colby School District is on paid administrative leave, while officials investigate a claim that the instructor sexually assaulted an 18-year-old man over three years ago.

District Administrator Steve Kolden confirms that a staff member brought an allegation forward on February 12th – and five days before that, the alleged victim contacted police in Marshfield.

Police Chief Gary Jepsen says the statute of limitations in that circumstance is three years, and the case goes beyond that time limit. Therefore, criminal charges will not be sought – and the Colby School District will decide on any appropriate punishment.

Kolden says he’s not sure when the school’s investigation will be finished. And he would not give until details until then.
