Federal authorities in Boston have charged seven Chinese nationals in connection with a multi-million-dollar illegal marijuana trafficking operation spanning Massachusetts and Maine. The investigation, conducted by the FBI Boston and Massachusetts State Police, uncovered a conspiracy involving the cultivation and distribution of marijuana through interconnected grow houses concealed within single-family properties. The operation also included money laundering and alien smuggling activities. Additionally, two Chinese nationals and a woman from New York have pleaded guilty to laundering over $90 million in drug proceeds linked to similar criminal enterprises. The charges highlight a coordinated effort to distribute kilograms of marijuana across the Northeastern United States.
