Alison J. Ramsdell U.S. Attorney | U.S. Attorney for the District of South Dakota
A Mission, South Dakota man has been sentenced to federal prison for assault resulting in serious bodily injury. U.S. District Judge Eric C. Schulte handed down the sentence on November 12, 2025.
Tyler Waukechon, 32, received a sentence of two years and six months in federal prison. He will also serve three years of supervised release and must pay a $100 special assessment to the Federal Crime Victims Fund.
Waukechon was indicted by a federal grand jury in February 2025 and pleaded guilty on August 7, 2025.
The conviction is related to an incident that took place in October 2024 on the Rosebud Sioux Indian Reservation. According to court records, Waukechon confronted another adult male at a residence in Mission and struck him in the face with a shovel. The victim suffered a deep laceration that required hospitalization. Waukechon was arrested later that day at a nearby residence.
The case was investigated by the Rosebud Sioux Tribe Law Enforcement Services. Supervisory Assistant U.S. Attorney Kirk Albertson prosecuted the case.
Waukechon was immediately remanded to the custody of the U.S. Marshals Service.
