Luis Munoz, 41, of Waterbury, was sentenced to 40 months in federal prison followed by three years of supervised release for his involvement in a drug trafficking organization operating in Waterbury. The sentence was handed down by U.S. District Judge Michael P. Shea in Hartford.
According to court documents and statements made during the proceedings, the FBI’s Waterbury Safe Streets Gang Task Force and other law enforcement agencies investigated two drug trafficking organizations based in Waterbury. One group was led by Angel Quiros and operated near William Street, while another was led by Daniel Diaz-Rivera and operated near Maple Avenue. The investigation used wiretaps, video surveillance, GPS tracking, and controlled purchases to reveal that both groups distributed cocaine, crack cocaine, and fentanyl through a network of sellers. Authorities said the organizations shared sources of supply and coordinated their activities.
Munoz was identified as a distributor of cocaine, crack cocaine, and fentanyl within the Quiros organization.
As a result of the investigation, Munoz, Quiros, Diaz-Rivera, and 14 others were charged with federal offenses. They were arrested on November 29, 2023. During the arrests, investigators executed several search warrants that resulted in the seizure of about 700 grams of crack cocaine, more than 900 vials of crack cocaine, approximately 200 grams of loose fentanyl, over 1,600 dose bags containing fentanyl or heroin, two stolen firearms with ammunition, and more than $39,000 in cash. From Munoz specifically, authorities seized about 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 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 on June 23, 2025.
The FBI’s Waterbury Safe Streets Gang Task Force includes members from several local law enforcement agencies as well as state departments. Additional support came from federal agencies including the DEA and Homeland Security Investigations.
