NEW ORLEANS, LOUISIANA – DWAN RILEY, age 37, a Plaquemines Parish, Louisiana resident, was sentenced on May 9, 2024 to 90 months imprisonment, 3 years of supervised release, and a mandatory $100 special assessment fee, announced U.S. Attorney Duane A. Evans.

RILEY previously pleaded guilty to conspiracy to distribute and possess with the intent to distribute quantities of fentanyl, heroin, and cocaine, in violation of Title 21, United States Code, Sections 841(a)(1), 841(b)(1)(C), and 846.

Drug Enforcement Administration (DEA) agents started investigating RILEY and other co-conspirators in October 2019 as a narcotics distributor in the New Orleans metropolitan area.  The investigation revealed HERBERT RICHARDSON and RAY MARSHALL were RILEY’s primary sources of supply for counterfeit oxycodone pills, which contained both heroin and fentanyl.

RILEY would subsequently distribute the narcotics to his own customers.
