Massachusetts man sentenced in Eastern Massachusetts/Rhode Island drug trafficking conspiracy after 20+kilos of drugs, firearms seized

BOSTON – A Brockton man was sentenced yesterday in federal court in Boston in connection with a wide-ranging drug trafficking conspiracy that that involved over 100 parcels containing kilograms of cocaine sent from Puerto Rico to various addresses throughout Eastern Massachusetts and Rhode Island. Investigators intercepted 10 parcels and seized more than 20 kilograms of cocaine from the mail stream.

According to the Massachusetts Department of Justice, Robert Monteiro, 40, was sentenced by U.S. District Court Chief Judge F. Dennis Saylor IV to 69 months in prison, to be followed by three years of supervised release. In July 2024, Monteiro was convicted by a federal jury of one count of conspiracy to distribute and to possess with intent to distribute cocaine. In July 2021, Monteiro was indicted alongside 10 co-defendants.

Beginning in February 2020, law enforcement investigated a drug trafficking organization operated by Patrick Joseph. Based on a wiretap investigation, Joseph coordinated the transportation of 10-20 kilograms of cocaine at a time from the Dominican Republic to Puerto Rico, and eventually to Massachusetts and Rhode Island via the U.S. Mail. During the investigation, cocaine was found concealed in two-kilogram quantities inside air fryers and cash boxes before being sent through the mail. Various firearms, 21 kilograms of cocaine and over $100,000 cash was also seized following the arrests in this investigation. Monteiro served as a member of Joseph’s drug trafficking organization, collecting packages and redistributing kilograms of cocaine that came in through the mail.

Joseph was sentenced in June 2024 to 138 months in prison followed by five years of supervised release.

Acting United States Attorney Joshua S. Levy; Ketty Larco-Ward, Inspector in Charge, United States Postal Inspection Service, Boston Division; Geoffrey Noble, Colonel of the Massachusetts State Police; and Boston Police Commissioner Michael Cox made the announcement today. Valuable assistance was provided by the Drug Enforcement Administration, New England Field Division and Homeland Security Investigations in New England. Assistant U.S. Attorneys Philip C. Cheng and Howard Locker of the Criminal Division prosecuted the case.
