Luis Munoz, also known as “P.R.” and “Puerto Rico,” was sentenced to 40 months in federal prison for his involvement in a Waterbury drug trafficking organization. The sentence was handed down by U.S. District Judge Michael P. Shea in Hartford, according to an announcement from David X. Sullivan, United States Attorney for the District of Connecticut. Munoz will also serve three years of supervised release after completing his prison term.
Authorities say that the FBI’s Waterbury Safe Streets Gang Task Force and other law enforcement agencies investigated two drug trafficking groups based in Waterbury. One group, led by Angel Quiros, operated near William Street, while another headed by Daniel Diaz-Rivera operated around Maple Avenue. Investigators used court-authorized wiretaps, video surveillance, GPS tracking of vehicles, and controlled narcotics purchases to uncover the operations. Both organizations distributed cocaine, crack cocaine, and fentanyl through a network of sellers who often worked together and shared suppliers.
Munoz was identified as distributing cocaine, crack cocaine, and fentanyl as part of the Quiros-led group.
The investigation resulted in federal charges against Munoz, Quiros, Diaz-Rivera, and 14 others. On November 29, 2023, authorities arrested several defendants including Munoz and executed multiple search warrants. They seized approximately 700 grams of crack cocaine; over 900 vials (“caps”) of crack; about 200 grams of loose fentanyl; more than 1,600 dose bags containing fentanyl or heroin; two stolen firearms; ammunition; and over $39,000 in cash. From Munoz specifically, investigators seized roughly 234 grams of cocaine, 22 grams of fentanyl, and $2,100 in cash.
On March 7, 2025, Munoz pleaded guilty to conspiracy to distribute and possess with intent to distribute controlled substances. He had been released on a $100,000 bond but must report to prison on January 16.
Quiros and Diaz-Rivera also pleaded guilty to related charges. Quiros received a sentence of 63 months imprisonment on August 19, 2025. Diaz-Rivera was sentenced to 210 months imprisonment on June 23, 2025.
The FBI’s Waterbury Safe Streets Gang Task Force includes personnel from the FBI itself as well as the Waterbury Police Department, Naugatuck Police Department, and Connecticut Department of Correction. Additional assistance came from the DEA; U.S. Marshals Service; Homeland Security Investigations (HSI); Connecticut State Police; Wolcott Police Department; and Meriden Police Department.
