PIERRE – United States Attorney Ron Parsons announced today that U.S. District Judge Eric C. Schulte has sentenced a man and woman, both from Rosebud, South Dakota, following their convictions for Voluntary Manslaughter.
Jamie Clairmont, a/k/a Jamie Clairmont-Rogers, age 42, pleaded guilty on January 26, 2026. On May 19, 2026, she was sentenced to five years and three 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.
Keanu Marshall, age 21, pleaded guilty on January 29, 2026. On May 26, 2026, he was sentenced to five years and three 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.
Clairmont and Marshall were indicted by a federal grand jury in November 2024.
The convictions stem from an incident that occurred on April 9, 2024, in Rosebud, South Dakota, in the Rosebud Sioux Indian Reservation. On that date, the victim, an adult male, was walking when he confronted a group of people. He picked up a piece of wood and swung it at Clairmont. Clairmont took the piece of wood and struck the victim with it. Marshall then repeatedly punched the victim, knocking him to the ground. The victim was hospitalized with traumatic injuries to the head and face, and he passed away on April 19, 2024.
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 Rosebud Sioux Tribe Law Enforcement Services. Supervisory Assistant U.S. Attorney Kirk Albertson prosecuted the case.
Clairmont and Marshall were immediately remanded to the custody of the U.S. Marshals Service at the conclusion of their individual sentencing hearings.
