CONCORD – Two Nashua men whose drug-trafficking cases went to federal court within the past couple years went before a judge this week, one for a sentencing hearing and the other to plead guilty as part of an agreement with prosecutors.

Marvin Morrison, 37, was sentenced to 15 months in federal prison, followed by four months of home confinement for his alleged participation in a conspiracy to distribute crack cocaine. Martin Sheehan, 27, entered a plea of guilty to fentanyl trafficking, which stems from allegations he sold fentanyl on two occasions in 2018 in Nashua. He is scheduled to be sentenced Sept. 1 in U.S. District Court. Nashua police arrested Sheehan in 2019 at a local motel, at which time they recovered more than 13 grams of fentanyl, authorities said.

Murray said that according to documents and statements made in court, Morrison “was a member of a drug trafficking organization that distributed crack cocaine and other drugs to various customers in the Nashua area.” Morrison pleaded guilty Feb. 18, Murray said. He said six other defendants in the case pleaded guilty.

Donald Johnson received 42 months in prison; Melvin Nooks, 120 months; and Mallory Nooks, 60 months. The others are either awaiting sentencing or trial.
