SIOUX FALLS - United States Attorney Ron Parsons announced today that Chief Judge Roberto A. Lange, U.S. District Court, sentenced a Sioux Falls, South Dakota, man convicted of Possession of a Firearm by a Prohibited Person. The sentencing took place on August 31, 2026.

Mohamed Mohamud Hassan, 22, was sentenced to one year and two 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.

This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department's Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN). Through PSN, the District of South Dakota seeks to bring together all levels of law enforcement and the communities they serve to reduce gun violence and make our neighborhoods safer for everyone.

This case was investigated by the Bureau of Alcohol, Tobacco, Firearms and Explosives, South Dakota Highway Patrol, Homeland Security Investigations, and the Sioux Falls Police Department. Assistant U.S. Attorney Mark Joyce prosecuted the case.

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