A Dukes County grand jury indicted three men last week on charges related to drug trafficking on Martha’s Vineyard.

Convening March 3, the grand jury handed down an indictment for Jeffrey Sylvia, 27, of Oak Bluffs, on charges of trafficking in heroin/morphine/opium, more than 36 grams and less than 100 grams; possessing to distribute a class A drug, subsequent offense; possessing a class B drug; possessing to distribute a class D drug, subsequent offense; and drug violation near school/park.

Mr. Sylvia was arrested in late July after Martha’s Vineyard Drug Task Force officers executed a search warrant at a house on Arrowhead Lane in Oak Bluffs, police said. According to police at the time, police allegedly found needles and other items related to drug use, and allegedly located a safe in Mr. Sylvia’s room that contained about 46 grams of heroin, three Suboxone strips, crushed Percocet pills, about one ounce of marijuana and almost $9,000 in cash.

Two New Bedford men were also indicted last week. Desmond J. Roderiques, 24. and Aaron M. Watkins, 28, are both charged with trafficking in heroin/morphine/opium, more than 18 grams and less than 36 grams; trafficking in cocaine, more than 36 grams and less than 100 grams; and conspiracy to violate drug law.

Mr. Watkins and Mr. Roderiques were arrested by drug task force officers in October as they departed a Steamship Authority ferry in Vineyard Haven. According to police, the two men were stopped as the car they were traveling in turned onto Water street after disembarking the ferry and police searched the men and the vehicle by authority of a search warrant issued earlier in the day. Police said they allegedly seized 53 grams of heroin, 23 grams of cocaine, and several containers of marijuana during the arrest, and the drugs had a total street value of $12,000. The drugs were allegedly concealed in the engine compartment of the car.

Police also executed a search warrant at home on Hye Way in Edgartown and said they seized 80 grams of marijuana, methadone pills, and narcotics paraphernalia. Police said they believed the two suspects and others allegedly used the home as a base to deal drugs on the Island.

Arraignments are currently scheduled for April 4.
