Parmelee Man Sentenced to Nearly Five Years in Federal Prison for Assaulting a Fellow Jail Inmate and Possessing a Firearm While a Felon

United States Attorney Alison J. Ramsdell announced that U.S. District Judge Eric C. Schulte has sentenced a Parmelee, South Dakota, man convicted of Assault with a Dangerous Weapon and Possession of a Firearm by a Prohibited Person. The sentencing took place on December 16, 2024.



Daryl John Plumman, age 32, was sentenced to four years and nine months in federal prison, followed by three years of supervised release, and ordered to pay a $200 special assessment to the Federal Crime Victims Fund.



Plumman was indicted by a federal grand jury in September 2023. He pleaded guilty on July 24, 2024.



The convictions stem from two different incidents that occurred in 2023 in the Rosebud Sioux Indian Reservation. On April 21, 2023, law enforcement was looking for Plumman in Parmelee in connection with an alleged assault that happened earlier in the day. Plumman was located sitting in the driver seat of a parked vehicle, with a loaded 9 mm pistol under his seat. He was previously convicted of Abusive Sexual Contact in federal court. As a result of this conviction, it is illegal for Plumman to possess firearms or ammunition.



On July 29, 2023, Plumman was an inmate at the Rosebud Sioux Tribe Adult Correctional Facility. On that day, Plumman and another man attacked a fellow inmate and assaulted him with a pencil.



The assault 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 and the Bureau of Alcohol, Tobacco, Firearms and Explosives. Assistant U.S. Attorneys Kirk Albertson and Brian Murphy prosecuted the case.



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