Several drug suppliers in Rockland and Orange Counties pleaded guilty earlier this week to felony charges. Among them, 35 year-old Marquis Gamble of Nyack. The group that pleaded guilty in Orange County court included firefighters, a former police officer, and members of so-called “outlaw motorcycle clubs.” Operation “Bread, White, and Blues” busted the drug rings in February. As the admitted supplier of cocaine to the group’s other members for distribution, Gamble faces 10-15 years in prison. He will be sentenced in October.
