Waterbury Drug Trafficker Sentenced to More Than 17 Years in Federal Prison

David X. Sullivan, United States Attorney for the District of Connecticut, announced that DANIEL DIAZ-RIVERA, also known as “Danny,” “Lupin,” “Lupito,” and “L,” 33, of Waterbury, was sentenced today by U.S. District Judge Michael P. Shea in Hartford to 210 months of imprisonment, followed by four years of supervised release, for heading a Waterbury drug trafficking organization.

According to court documents and statements made in court, the FBI’s Waterbury Safe Streets Gang Task Force and other law enforcement agencies investigated two drug trafficking organizations based in the city of Waterbury.  One organization was headed by Angel Quiros, also known as “Papa John,” and operated in the area of William Street, and the other was headed by Diaz-Rivera and operated in the area of Maple Avenue.  The investigation, which included court-authorized wiretaps on multiple phones, video surveillance, GPS tracking of vehicles, and numerous controlled purchases of narcotics, revealed that the two organizations distributed cocaine, crack, and fentanyl through a network of sellers.  The organizations shared sources of supply and worked together to further their operations.

The Diaz-Rivera organization sold crack and fentanyl all hours of the day and night outside of a bodega on Maple Avenue in Waterbury.  Diaz-Rivera oversaw several shift bosses who, in turn, oversaw street-level distributors.  During the investigation, investigators made two controlled purchases of crack directly from Diaz-Rivera.  Diaz-Rivera used violence and threats to control others in connection with his drug distribution network.

Quiros, Diaz-Rivera, and 15 other individuals were charged with federal offenses as a result of the investigation.  Diaz-Rivera and several codefendants were arrested on November 29, 2023.  In association with the arrests, investigators executed multiple search warrants and seized approximately 700 grams of crack cocaine, more than 900 vials (“caps”) of crack, approximately 200 grams of loose fentanyl, more than 1,600 dose bags of fentanyl/heroin, two stolen firearms, numerous rounds of ammunition, and more than $39,000 in cash, including more than $13,000 that was found in Diaz-Rivera’s vehicle.

On January 24, 2025, Diaz-Rivera pleaded guilty to conspiracy to distribute and to possess with intent to distribute 500 grams or more of cocaine.  He has been detained since his arrest.

Quiros pleaded guilty to the same charge on February 11, 2025, and awaits sentencing.

The FBI’s Waterbury Safe Streets Gang Task includes members from the FBI, the Waterbury Police Department, the Naugatuck Police Department, and the Connecticut Department of Correction.  The DEA, U.S. Marshals Service, Homeland Security Investigations (HSI), Connecticut State Police, Wolcott Police Department, and Meriden Police Department have assisted the investigation.

This case is being prosecuted by Assistant U.S. Attorneys Natasha Freismuth and Shan Patel through the Organized Crime Drug Enforcement Task Forces (OCDETF) Program.  Additional information about the OCDETF Program can be found at https://www.justice.gov/OCDETF.

U.S. Attorney Sullivan thanked the Waterbury State Attorney’s Office for its cooperation in the investigation and prosecution of this case.
