Sioux Falls Felon Garrett Gets 4.5 Years for Ammo

SIOUX FALLS, SD – Lamont Victor Garrett, 52, of Sioux Falls is headed to federal prison after a jury found him guilty of illegally possessing ammunition. Chief Judge Roberto A. Lange handed down a sentence of four years and six months on September 8, 2025, followed by three years of supervised release. Garrett will also be required to pay a $100 special assessment to the Federal Crime Victims Fund.

The case stems from an August 21, 2024, search of Garrett’s Sioux Falls residence. Law enforcement discovered ammunition on the premises, triggering the federal charge of Possession of Ammunition by a Prohibited Person. Garrett, a repeat offender, was legally barred from owning firearms or ammunition due to previous felony convictions – details of those convictions were not immediately released.

Garrett was indicted by a federal grand jury in November 2024, and the trial concluded with a guilty verdict on June 11, 2025. The prosecution, led by Supervisory Assistant U.S. Attorney Connie Larson, successfully argued that Garrett knowingly violated federal law by possessing the ammunition despite his prohibited status. The evidence presented clearly demonstrated his inability to legally own such items.

The investigation was a coordinated effort between the Sioux Falls Police Department, Homeland Security Investigations, and the Bureau of Alcohol, Tobacco, Firearms and Explosives. This multi-agency approach underscores the seriousness with which federal authorities view firearms violations, particularly when committed by individuals with criminal histories. Sources within the ATF stated that the ammunition type was not disclosed.

U.S. Attorney Alison J. Ramsdell highlighted that this case is part of Project Safe Neighborhoods (PSN), a violent crime reduction program focused on strengthening community trust, supporting violence prevention organizations, and implementing strategic enforcement. The Department launched a renewed PSN strategy in May 2021, aiming to measurably reduce violent crime and gun violence across the nation.

Following the sentencing, Garrett was immediately taken into the custody of the U.S. Marshals Service to begin serving his 4.5-year sentence. His future remains uncertain, but this conviction sends a clear message: possessing ammunition while prohibited carries significant consequences under federal law. The Grimy Times will continue to follow this case and report on any further developments.
