Leader of South Shore Drug Trafficking Ring Sentenced to 32 Years in Prison

Press Release

Kilograms of fentanyl, fentanyl analogue and cocaine; firearms; and hundreds of thousands of dollars in drug proceeds seized

BOSTON - The leader of a large-scale drug trafficking conspiracy that distributed fentanyl, fentanyl analogue and cocaine throughout Quincy and Weymouth was sentenced on Oct. 15, 2024 in federal court in Boston.

Aderito Patrick Amado, 34, of Brockton and Quincy, was sentenced by U.S. Senior District Court Judge William G. Young to 32 years in prison to be followed by 10 years supervised release. In June 2024, Amado was convicted by a federal jury of two counts of possession with intent to distribute 400 grams or more of fentanyl, 100 grams or more of a fentanyl analogue and 500 grams or more of cocaine - and conspiracy to do the same; one count of possession with intent to distribute cocaine, 40 grams or more of fentanyl and 100 grams or more of fentanyl analogue; one count of possession with intent to distribute cocaine and 40 grams or more of fentanyl; two counts of possessing firearms as a convicted felon; and one count of possessing a firearm in furtherance of a drug offense. The Court sentenced Amado to 27 years in prison on counts one through four and counts six through seven, to be followed by five consecutive years in prison on count five. At sentencing, the Court applied a stash house and leadership enhancement and found that Amado obstructed justice at trial through his testimony.

In September 2022, Amado was indicted by a federal grand jury along with co-defendants Erica Vieira, Neylton Fontes and Chaasad Cyprien. The defendants were subsequently charged in a superseding indictment in December 2022 and, later, a second superseding indictment in October 2023. Amado was charged in a third superseding indictment in May 2024.

"Mr. Amado was the leader of an organization that pumped multiple kilograms of dangerous and deadly drugs into our communities, including fentanyl and fentanyl analogue. He will now have more than three decades in prison to contemplate his critical role in driving fentanyl addiction and contributing to overdose deaths through his wholesale and street-level distribution all in pursuit of the almighty buck," said Acting United States Attorney Joshua S. Levy. "This case demonstrates that people like Aderito Patrick Amado, who terrorize communities with their guns, drugs, and manipulation of others, will pay a heavy price. This was an exceptionally skilled and dogged investigation by the prosecutors in our office, the FBI, the Quincy Police and other law enforcement partners. This lengthy sentence should send a strong message to others, do not engage in the toxic brew of illicit narcotics and guns or you will go to jail for a very long time."

"Aderito Patrick Amado and his crew were a crime wave unto themselves. As the leader of this large-scale drug trafficking operation that brought in and sold multi-kilo quantities of fentanyl and cocaine, protected by high-capacity firearms, Mr. Amado could have cared less about this area's raging opioid crisis," said Jodi Cohen, Special Agent in Charge of the Federal Bureau of Investigation Boston Division. "The FBI's Metro Boston Gang Task Force worked with our law enforcement partners on the South Shore to make this case that led to Amado being sent to prison for the next three decades, and we're all gratified to see such a prolific criminal finally held accountable."

"I would like to thank the Detectives assigned to the Quincy Police Drug Control Unit, our local, state and federal partners and particularly the prosecutors from the U.S. Attorney's office for bringing this case forward. Taking this individual off the streets undoubtedly saved lives in our community," said Quincy Police Chief Mark Kennedy.

Until at least January 2021, Amado helped lead a conspiracy to distribute fentanyl, fentanyl analogue and cocaine in and around the Quincy and Weymouth areas. The investigation determined that the drug distribution conspiracy operated primarily out of a stash house in Weymouth, with additional evidence located inside Amado's apartment in Quincy and in his vehicle.

Specifically, a January 2021 search of Amado's Quincy apartment resulted in over 40 grams of fentanyl, a quantity of cocaine, over $270,000 in cash, a money counter, a loaded Glock and ammunition being recovered. Amado's vehicle contained over 40 grams of fentanyl and over 100 grams of fentanyl analogue, along with approximately $50,000 cash and multiple cellphones. Additionally, the Weymouth stash house was, in essence, a drug factory - housing two presses used to form controlled substances into kilogram-sized bricks and extensive drug paraphernalia, including blenders, digital scales, cutting agents, a money counter, and packaging equipment. The stash house also contained more than 10 kilograms of fentanyl, fentanyl analogue and cocaine as well as three firearms and ammunition, including two high-capacity magazines and a speed loader. One firearm was equipped with a laser beam and another firearm had a custom slide. Given Amado's status as a felon, he is prohibited from possessing any firearms. At least one of Amado's fingerprints were recovered on the ammunition tray located inside one of the boxes of ammunition in the stash house. His fingerprints were also recovered on one of the bags of cutting agents.

Information from a court-ordered GPS ankle monitor placed Amado at both his residence and the stash location nearly every day over a two-month period while on probation for a state drug conviction. Additionally, web history information from one of Amado's devices showed that he conducted online reviews of various items ultimately recovered from the stash house, including the kilogram presses, firearms and cutting agents.

Vieira pleaded guilty in May 2024 and is scheduled to be sentenced on March 24, 2025. Fontes pleaded guilty in May 2024 and was sentenced in September 2024 to two years in prison and three years of supervised release. Cyprien pleaded guilty in April 2024 and in July 2024 was sentenced to two years in prison and three years of supervised release.

Acting U.S. Attorney Joshua S. Levy, FBI SAC Cohen and Quincy Chief Kennedy made the announcement. Valuable assistance in the investigation was provided by the Weymouth, Braintree, Randolph and Brockton Police Departments. Assistant U.S. Attorneys Kaitlin R. O'Donnell and Philip A. Mallard of the Criminal Division are prosecuting the case.
