An Omaha man has been sentenced to three years’ probation after dumping dirt from a front-end loader truck at the feet of Internal Revenue Service officers who were trying to seize his boss’s dump truck. U.S. Magistrate Judge Thomas D. Thalken sentenced Walter M. Trizila, age 45, to a three-year term of probation last Thursday, following a misdemeanor conviction for assault, resisting or impeding a federal officer. According to prosecutors, Trizila encountered several IRS officers who were trying to seize a dump truck owned by his employer on Nov. 8, 2012 and became confrontational with them. He then entered a front-end loader vehicle, scooped a full load of dirt into the bucket and drove directly at the IRS officers. Trizila stopped the front-end loader vehicle just short of striking an IRS officer, after which he dumped the entire load of dirt at the IRS officers’ feet and in front of the dump truck that the officers were trying to seize.
