STILLWATER, MN (WTAQ) - A former teacher in northwest Wisconsin is charged with having sex with students at his home in Minnesota.
Washington County prosecutors filed two counts of third-degree criminal sex assault Thursday against 36-year-old Matthew Koenen of Stillwater.
Authorities said Koenen had relationships with several female students at Grantsburg High School in person, through text messages, and on the Internet.
Officials said it led to Koenen's sexual activity at his home, where he allegedly had sex with one student while his child was taking a nap. That reportedly happened in August of 2012.
Koenen quit his teaching post at Grantsburg after the school district learned of the allegations. He was not in custody at last word.
