Leader of South Shore Drug Trafficking Ring Convicted by Federal Jury

BOSTON – The leader of a large-scale drug trafficking conspiracy that distributed fentanyl, fentanyl analogue and cocaine throughout Quincy and Weymouth has been convicted by a federal jury in Boston. 

Aderito Patrick Amado, 34, of Brockton and Quincy, was convicted on June 21, 2024 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. U.S. Senior District Court Judge William G. Young scheduled sentencing for Oct. 8, 2024.

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. 

“This case is emblematic of the fentanyl crisis facing our communities. Dozens of pounds of illegal drugs, high-capacity firearms, and hundreds of thousands of dollars all in the hands of a man while he was already on probation for a state drug conviction. Mr. Amado will now pay a severe price for choosing to pump this poison onto the streets of Massachusetts,” said Acting United States Attorney Joshua S. Levy. “Mr. Amado had drugs, cash and guns everywhere – in his apartment and his stash house. Given the unrelenting scourge of illegal drugs and overdose deaths, this office is as committed as ever to prosecuting drug-dealing criminals. This case should serve as a warning to others: if you want to engage in illicit narcotics activities, we will find you and prosecute you to the fullest extent of the law.”

“Aderito Patrick Amado was part of a conspiracy that brought in and sold vast amounts of fentanyl and cocaine all over southeastern Massachusetts. We’re talking multi-kilo quantities of dangerous drugs that he protected using illegal firearms,” said Jodi Cohen, Special Agent in Charge of the Federal Bureau of Investigation, Boston Division. “Today’s conviction is a win for the FBI’s Metro Boston Gang Task Force as we work with our partners to get dangerous drugs and criminals off the street. The ultimate goal here is to free our communities from the clutches of violent drug traffickers who have zero regard for the incredible damage they inflict on people’s lives.”

“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 his Jeep Cherokee. 

Specifically, a January 2021 search of Amado’s Quincy apartment resulted in over 40 grams of fentanyl, over $270,000 in cash, a money counter and a loaded Glock being recovered. 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 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. Given Amado’s status as a felon, he is prohibited from possessing a firearm.

Evidence presented at trial included information from a court-ordered GPS ankle monitor that placed Amado at both his residence and the stash location essentially 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 Sept. 4, 2024. Fontes pleaded guilty in May 2024 and is scheduled to be sentenced on Sept. 16, 2024 and Cyprien pleaded guilty in April 2024 and is scheduled to be sentenced on July 17, 2024.

The charge of possession with intent to distribute 400 grams or more of fentanyl, 100 grams or more of a fentanyl analogue, 500 grams or more of cocaine, and conspiracy to do the same, provides for a mandatory minimum sentence of 10 years up to life in prison, at least five years and up to a lifetime of supervised release and a fine of up to $10 million. The charge of possession with intent to distribute cocaine and 40 grams or more of fentanyl provides for a mandatory minimum sentence of five years and up to 40 years in prison, at least four years and up to a lifetime of supervised release and a fine of up to $5 million. The charge of possessing a firearm as a convicted felon provides for a sentence of up to 10 years in prison, three years of supervised release and a fine of $250,000. The charge of possessing a firearm in furtherance of a drug offense provides for a sentence of at least five years and up to life in prison, to be served from and after the term of imprisonment imposed for any other count, up to five years of supervised release and a fine of up to $250,000. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and statutes which govern the determination of a sentence in a criminal case.

Acting U.S. Attorney Joshua S. Levy, FBI SAC Cohen and 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 Organized Crime & Gang Unit are prosecuting the case.
