Eagle Butte Man Sentenced to Nearly 6 ½ Years in Federal Prison for Assault

PIERRE - United States Attorney Ron Parsons announced today that U.S. District Judge Eric C. Schulte has sentenced a man from Eagle Butte, South Dakota, convicted of Assault Resulting in Serious Bodily Injury. The sentencing took place on September 30, 2025.

Jody Jeremy Dupris, a/k/a Jeremy Jody Dupris, age 45, was sentenced to six years and four months in federal prison, followed by three years of supervised release, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund.

Dupris was indicted by a federal grand jury in September 2024. He pleaded guilty on June 26, 2025.

The conviction stems from an incident that occurred in the early morning hours of May 2024 in Eagle Butte, SD, within the Cheyenne River Sioux Indian Reservation. Dupris went to the victim’s residence and demanded to be let in. After the victim allowed him into the residence, Dupris stabbed the victim in his right shoulder with a box-cutter/utility knife, causing a deep laceration and bleeding. The victim was able to get away and seek medical care after Dupris passed out. When law enforcement officers entered the victim’s residence, they found Dupris lying on the floor with the weapon nearby.

This matter was prosecuted by the U.S. Attorney’s Office because the Major Crimes Act, a federal statute, mandates that certain violent crimes alleged to have occurred in Indian Country be prosecuted in Federal court as opposed to State court.

This case was investigated by the FBI and the Cheyenne River Sioux Tribe Law Enforcement Services. Assistant U.S. Attorney Wayne Venhuizen prosecuted the case.

Dupris was immediately remanded to the custody of the U.S. Marshals Service.
