SPARTA, Wis. – A Tomah school teacher was sentenced to 10 years in prison for repeatedly forcing a 14-year-old boy into sex with her in the school basement. Anne Nelson-Koch, 75, had been found guilty in July on 25 separate charges, including 12 counts of sexual assault. Monroe County Judge Richard Radcliffe issued the sentence, which he ordered be capped by supervision for 15 years. With the multiple convictions, Nelson-Koch had faced a maximum sentence of 600 years. At the sentencing, the victim’s father called for Nelson-Koch to be sent away for life. Prosecutor Sarah Skiles also argued for a long sentence. Nelson-Koch had made a “virtuous masquerade that was a calculated attempt to conceal her predatory tendencies,” Skiles said.
