Waterbury Man Sentenced to 40 Months in Federal Drug Case Tied to Two City Networks

Waterbury, CT — A Waterbury man was sentenced to 40 months in federal prison for his role in a drug network that prosecutors say helped move cocaine, crack, and fentanyl through two major distribution points in the city.

According to U.S. Attorney David X. Sullivan, Luis “P.R.” Munoz, 41, was sentenced in federal court in Hartford to 40 months of imprisonment followed by three years of supervised release. Munoz was part of a narcotics operation run by Angel Quiros that operated primarily in the William Street corridor. A second, interconnected organization led by Daniel Diaz-Rivera ran its distribution out of the Maple Avenue area.

Federal agents with the FBI’s Waterbury Safe Streets Gang Task Force and multiple state and local agencies spent months investigating the groups using wiretaps, video surveillance, GPS tracking, and controlled purchases. Prosecutors say the two organizations shared suppliers, coordinated operations, and sold narcotics “all hours of the day and night.”

During the coordinated arrests on November 29, 2023, investigators seized more than 700 grams of crack cocaine, over 1,600 dose bags of fentanyl/heroin, two stolen firearms, ammunition, and $39,000 in cash. From Munoz specifically, agents seized 234 grams of cocaine, 22 grams of fentanyl, and $2,100 in cash.

Munoz pleaded guilty on March 7, 2025, to conspiracy to distribute and to possess with intent to distribute controlled substances. He remains free on a $100,000 bond and must report to prison on January 16.

Quiros and Diaz-Rivera have already been sentenced. Quiros received 63 months, while Diaz-Rivera received 210 months in federal prison.

The investigation involved the FBI, Waterbury Police, Naugatuck Police, Connecticut DOC, DEA, HSI, U.S. Marshals, State Police, and local departments from Meriden and Wolcott.
