A Green Bay man who almost fatally stabbed another man at the 2011 Mifflin Street Block Party was sentenced Friday to 2½ years in prison. Colin J. Rosenow, 23, wept as he told Matthew Warnert that he was sorry for what happened on April 30, 2011, and asked for his forgiveness. ?I do not expect to be forgiven just because I said sorry,? Rosenow said.
