(Anoka, MN)  —  A former Anoka middle school teacher will spend the next three decades in prison.  On Wednesday, 48-year-old Jefferson Fietek was sentenced to 30-years in prison for sexually abusing five boys at the Anoka Middle School for the Arts and participants in the Young Artists Initiative.  According to reports, the abuse took place over the course of a decade between 2009 and 2019.  In court yesterday, Fietek apologized to his victims and said blame should only be placed on him.  The sentencing comes after the disgraced teacher pleaded guilty in August to ten counts of criminal sexual conduct.
