David Kruchten, 39, of Cottage Grove, Wisconsin, earlier pleaded guilty to one count of attempting to produce child pornography.
Prosecutors alleged Kruchten used his position as a business teacher at Madison East High School to secretly videotape students during field trips in Wisconsin and Minnesota.
According to court documents, he accompanied East High’s business club students on overnight trips to Wisconsin Dells and Lake Geneva as well as Minneapolis in 2019. Students discovered hidden cameras planted in air fresheners in their hotel rooms during the Minneapolis trip. Investigators discovered similar air freshener cans in photos taken by students during the Wisconsin trips, prosecutors said.
Kruchten was charged last year with multiple counts of attempting to produce child pornography and resigned from his teaching job.
In an eight-page handwritten letter filed earlier this week in U.S. District Court, Kruchten wrote that he started spying on family “to deal with stress and fulfill a need for adrenaline” and to find out what they said about him when he wasn’t around, the Wisconsin State Journal reported.
“That was not my goal when I went into teaching and it was not my goal when I started on this course of behavior,” Kruchten wrote. “My goal was not a collection of child pornography. My interest in these voyeuristic videos was not to capture students engaged in sex acts, my interest was the same (as) it was with my grandparents, and my pets and my wife — to see what people do when I’m not there.”
However, he wrote, it would be a lie to say there was “zero sexual component.”
Peterson also sentenced Kruchten to 20 years of supervised release to follow his time in prison.
