Maryland fentanyl supplier sentenced to seven years in prison

ALEXANDRIA, Va. – A Maryland man was sentenced today to seven years in prison for conspiracy to distribute fentanyl.

According to court documents, Mamud Sesay, 36, of Bowie, was a source of supply for fentanyl for customers, which included fentanyl redistributors. Sesay also sold fentanyl pills from his home. The pills Sesay distributed were light blue and imprinted with “M” on one side, and “30” on the other to resemble legitimate, 30-milligram oxycodone pills.

On Nov. 26, 2023, Phillip Donnell Mosby, 36, of Alexandria, contacted Sesay asking for 2,000 fentanyl pills. On November 27, 2023, Sesay met Mosby and distributed the pills to him. Mosby redistributed the pills in Arlington County later that day.

On April 15, 2024, Mosby contacted Sesay again asking for 4,000 fentanyl pills, and Sesay met Mosby at a gas station later that day and distributed the pills to Mosby. The following day, Mosby was arrested in Maryland in connection with his involvement in the conspiracy. Law enforcement searched Mosby’s Lexus and found approximately 4,000 fentanyl pills.

On Oct. 17, 2024, law enforcement searched Sesay’s residence and seized over 5,000 pills and approximately $2,500.

Mosby pled guilty on June 20, 2024, to conspiracy to distribute fentanyl and was sentenced on Sept. 25, 2024, to 10 years in prison.
