A 76-year-old New Ulm man that had been facing felony terroristic threats charges for threatening a jail administrator was convicted of lesser charges on Tuesday in Brown County Court. Duane Charles Marstone pleaded guilty to disorderly conduct and obstructing the legal process, and the terroristic threats and an assaulting a peace officer charge were dismissed. Marstone had been booked into the Brown County Jail on a probation violation, but upon his release had begun arguing with the jail administrator over the amount of money that had been in his jail account. He then allegedly threatened to run over the officer when he saw him on the street, and he was arrested and taken back into the jail. In court on Tuesday he was sentenced to 13 days in jail for the incident and 2 years of supervised probation. He will also be required to pay over a thousand dollars in fines and restitution and attend anger management classes.
