Marlon Oliver, Jr., Domestic Assault by an Habitual Offender, South Dakota 2026
Man Sentenced to Over 2 Years in Prison for Domestic Assault by an Habitual Offender
Pierre, SD - Marlon Oliver, Jr., a 41-year-old man from Rosebud, South Dakota, has been sentenced to over two years in federal prison for domestic assault by an habitual offender.
According to a sentencing order issued by U.S. District Judge Eric C. Schulte on April 20, 2026, Oliver was sentenced to a total of two years and ten 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.
The convictions stem from two separate incidents that occurred in Todd County on the Rosebud Sioux Indian Reservation. On October 11, 2024, Oliver was at the residence of his domestic partner, argued with her, and then assaulted her by shoving her. On December 1, 2024, Oliver was again at the residence of his domestic partner when she told him to leave. Oliver refused to leave and then threatened her with a knife.
At the time of both incidents, Oliver had two prior convictions in Rosebud Sioux Tribal Court for domestic assault. 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. Oliver was immediately remanded to the custody of the U.S. Marshals Service.
Marlon Oliver, Jr., 41, was sentenced to 2 years and 10 months in federal prison, followed by 3 years of supervised release, and ordered to pay $200 in special assessment.
