Sioux Falls Man Sentenced to 4 ½ Years in Federal Prison for Possessing Ammunition as a Felon

SIOUX FALLS - United States Attorney Alison J. Ramsdell announced today that Chief Judge Roberto A. Lange has sentenced a man from Sioux Falls, South Dakota, convicted of Possession of Ammunition by a Prohibited Person. The sentencing took place on September 8, 2025.

Lamont Victor Garrett, 52, was sentenced to four years and six 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.

Garrett was indicted for Possession of Ammunition by a Prohibited Person by a federal grand jury in November 2024. He was found guilty by a jury on June 11, 2025.

Garrett possessed ammunition in his residence in Sioux Falls on August 21, 2024. The ammunition was discovered when law enforcement officers executed a search warrant at the residence. Garrett is prohibited from possessing firearms and ammunition because of his previous felony convictions.

This case was investigated by the Sioux Falls Police Department and Homeland Security Investigations, as well as the Bureau of Alcohol, Tobacco, Firearms and Explosives. Supervisory Assistant U.S. Attorney Connie Larson prosecuted the case.

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.

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