Quincey Oneil Jackson and Quinton Oneil Jackson, twin brothers from Columbia, South Carolina, have been sentenced to more than 15 years each in federal prison after admitting their involvement in a conspiracy to possess with intent to distribute five kilograms or more of illegal drugs.
Court records revealed that the Jackson brothers operated a large-scale drug trafficking scheme between 2020 and July 2024. Their activities involved distributing cocaine, methamphetamine, and fentanyl. Law enforcement officers executed a search warrant at their shared residence on April 12, 2024, where they discovered methamphetamine, fentanyl, marijuana, and a firearm.
United States District Judge Sherri A. Lydon imposed sentences of 188 months’ imprisonment for both men. Each will also serve a period of court-ordered supervision following their release. Federal sentencing does not allow for parole.
The investigation was conducted by several agencies: the Drug Enforcement Administration; the Clarendon County Sheriff’s Office; the Richland County Sheriff’s Department; the City of Columbia Police Department; and the Lexington County Sheriff’s Department. Assistant U.S. Attorney Elizabeth Major is handling prosecution.
“There is no parole in the federal system,” according to information provided by authorities.
