Rosebud Man Sentenced for Prohibited Person in Possession of a Firearm

PIERRE - United States Attorney Alison J. Ramsdell announced today that Chief Judge Roberto A. Lange, U.S. District Court, has sentenced a Rosebud, South Dakota man convicted of Possession of a Firearm by a Prohibited Person. The sentencing took place on July 31, 2023.

Isaiah Lucas Beck, age 20, was sentenced to two years and ten months in prison, followed by three years of supervised release, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund. He was also ordered to forfeit multiple firearms involved in the matter.

Beck was indicted for Possession of a Firearm by a Prohibited Person by a federal grand jury in February of 2023. He pleaded guilty on May 1, 2023.

On August 31, 2022, Beck had a verbal confrontation with his father on Highway 83, south of Mission, South Dakota. During the argument, Beck’s father removed a Smith & Wesson pistol and a Del-Ton Incorporated rifle from Beck’s possession. The firearms belonged to Beck, who was an unlawful user of a controlled substance, thus prohibited from possessing any firearms. Both firearms were identified as being shipped and transported in interstate commerce and foreign commerce.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the Department launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.

This case was investigated by the Rosebud Sioux Tribe Law Enforcement Services and the Bureau of Alcohol, Tobacco, Firearms, and Explosives. Assistant U.S. Attorney Abby Roesler prosecuted the case.

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