A Sioux Falls man has been sentenced to more than four years in federal prison after being convicted of possessing a firearm as a felon. U.S. District Judge Karen E. Schreier handed down the sentence to Quincy Lamar Johnson, 35, on August 18, 2025.
Johnson received a sentence of four years and three months in federal prison, followed by three years of supervised release. He was also ordered to pay a $100 special assessment to the Federal Crime Victims Fund.
The conviction stems from an incident in July 2024 when Johnson was involved in a motor vehicle accident in Sioux Falls and was seriously injured. When officers removed him from the vehicle, they found a bag containing two 9mm pistols on the floorboard. At that time, Johnson was prohibited from possessing firearms due to previous felony convictions in Georgia for aggravated assault, assault with a firearm, and possession of a firearm by a felon or addict.
Johnson was indicted by a federal grand jury for Possession of a Firearm by a Prohibited Person in February 2025 and pleaded guilty on May 5, 2025.
“This case and others like it demonstrate the effective partnership between the Sioux Falls Police Department and federal law enforcement,” said U.S. Attorney Alison J. Ramsdell. “Working together, we are interrupting violence in the community by removing illegally possessed firearms from our neighborhoods and holding violent offenders to account in federal court.”
Federal prosecutions for firearm offenses are part of Operation Take Back America, which brings together resources from the Department of Justice’s Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN). The initiative aims to reduce gun violence and improve safety through collaboration among various law enforcement agencies and communities.
The investigation was conducted by the Sioux Falls Police Department and Homeland Security Investigations. Special Assistant U.S. Attorney Mark Joyce prosecuted the case.
Following sentencing, Johnson was remanded into custody of the U.S. Marshals Service.
