An elderly former teacher from Tomah is headed to prison for ten-years for the abuse of a teenage boy at a private school.
A judge this week sentenced 74-year-old Anne Nelson-Koch to a decade behind bars. Investigators say she repeatedly sexually abused a 14-year-old boy in the basement of a Tomah private school during the 2016-2017 school year. Following her prison term, she will spend 15 years on probation.
