In a separate matter, Michael Silvia 22, of Rhode Island and Winter Harbor was indicted on three drug counts: one count of possession with intent to distribute cocaine, one count of possession with intent to distribute marijuana and one count of possession of a firearm in furtherance of drug trafficking.
