MANKATO-October 4, 2012-(KMKO)-A predatory offender has been sent back to prison after allegedly calling a man a "child molester" and punching him in the head. 50-year-old Timothy Black had been sought by police for failing to register his address. Black entered a guilty plea to knowingly violating registration requirements. He was sentenced to two years in prison with credit for 129 days served. The sentence does not include the possibility of good time, because Black used drugs while on furlough.
