Not all sex offenders in Minnesota go to prison. In some cases, a court may decide that such a criminal should be held in a treatment center. Minnesota houses nearly 700 sex offenders in treatment facilities at St. Peter and Moose Lake, and $73 million is spent every year to lock these offenders up. In the last 20 years, however, only one person has ever been released from one of these centers. On Nov. 8, a panel of judges scheduled a hearing to determine whether there should be a second.
