Richland County Felon Sentenced to Federal Prison for Gun Charge

COLUMBIA, S.C. - Yashawnus Leekean Patterson, 45, of Columbia, has been sentenced to eight years in federal prison after being convicted of being a felon in possession of a firearm. Patterson was convicted by a federal jury following a trial in June 2025.

Evidence presented at trial included testimony and body worn camera footage showing two Columbia Police Department officers responding to a hotel in downtown Columbia to assist in removing Patterson, who was no longer staying at that hotel. After being asked to place Patterson on trespass notice, officers learned he was wanted on a bench warrant from the Cayce Police Department and arrested him. When officers searched him, they located a loaded 9mm pistol in the front of his waistband, a 30-round extended magazine in his backpack, and a total of 74 rounds of 9mm ammunition on his person and his other belongings. Patterson acknowledged to officers that he knew he was not legally allowed to possess a firearm.

Patterson has an extensive record of felony convictions dating back to 1998, including convictions for criminal sexual conduct with a minor in the second degree, strong-arm robbery, assault and battery of a high and aggravated nature.

United States District Judge Mary G. Lewis sentenced Patterson to 96 months imprisonment, to be followed by a three-year term of court-ordered supervision. There is no parole in the federal system.

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 Bureau of Alcohol, Tobacco, Firearms and Explosives and the City of Columbia Police Department. Assistant U.S. Attorney Elizabeth Major prosecuted the case.
