U.S. Attorney's Office, District of South Dakota

United States Attorney Randolph J. Seiler announced that an Eagle Butte, South Dakota, man has been indicted by a federal grand jury for Assaulting, Resisting, Opposing, and Impeding a Federal Officer.

Matthew Dupris, age 29, was indicted on June 14, 2017. He appeared before U.S. Magistrate Judge Mark A. Moreno on June 16, 2017, and pled not guilty to the Indictment.

The maximum penalty upon conviction is up to 8 years in custody and/or a $250,000 fine, 3 years of supervised release, and up to $100 to the Federal Crime Victims Fund. Restitution may also be ordered.

The Indictment alleges that on May 25, 2017, Dupris forcibly assaulted, resisted, opposed, impeded, and interfered with an officer with the Cheyenne River Sioux Tribe, while the officer was engaged in the performance of his official duties.

The charge is merely an accusation and Dupris is presumed innocent until and unless proven guilty.

The investigation is being conducted by the Cheyenne River Sioux Tribe Law Enforcement Services. Assistant U.S. Attorney Jay Miller is prosecuting the case.

Dupris was released on bond pending trial. A trial date has not been set.
