Rosebud Man Sentenced for Assault on Federal Officer

PIERRE - United States Attorney Alison J. Ramsdell announced today that Chief Judge Robert A. Lange, U.S. District Court, has sentenced a Rosebud, South Dakota man convicted of Assaulting, Resisting and Impeding a Federal Officer. The sentencing took place on July 22, 2024.

Robert Kills Plenty, age 27, was sentenced to six months in federal prison, followed by six months of home confinement, and 30 months of supervised release, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund.

Kills Plenty was indicted by a federal grand jury in February of 2023. He pleaded guilty on March 6, 2024.

On November 24, 2022, the Rosebud Sioux Tribe Law Enforcement Services operated a sobriety checkpoint near St. Francis, South Dakota, and Kills Plenty drove a vehicle through the inspection area. Kills Plenty was directed to pull over for a further DWI investigation. Instead, he failed to comply and fled the checkpoint in his vehicle, leading officers on a high-speed chase. Later, he stopped his vehicle and was apprehended. As he was being transported to the Rosebud Sioux Tribe Adult Corrections Facility (RSTACF), he became argumentative and combative. Once at the jail, he argued with jail staff and spat upon a correctional officer, striking the officer in the face with saliva. At the time of the assault, the officer was employed by the RSTACF pursuant to a contract between the Rosebud Sioux Tribe and the U.S. Department of Interior, Bureau of Indian Affairs.

This case was investigated by the Rosebud Sioux Tribe Law Enforcement Services. Assistant U.S. Attorney Tim Maher prosecuted the case.

Kills Plenty was immediately remanded to the custody of the U.S. Marshal to serve his sentence.
