Luis Munoz, 41, of Waterbury, was sentenced to 40 months in federal prison and three years of supervised release for his involvement in a drug trafficking organization based in Waterbury. The sentence was handed down by U.S. District Judge Michael P. Shea in Hartford.
The investigation into the drug operations was conducted by the FBI’s Waterbury Safe Streets Gang Task Force and other law enforcement agencies. Authorities identified two primary organizations: one led by Angel Quiros operating near William Street, and another headed by Daniel Diaz-Rivera on Maple Avenue. Investigators used wiretaps, video surveillance, GPS tracking, and controlled narcotics purchases to uncover how both groups distributed cocaine, crack cocaine, and fentanyl through a network of sellers at all hours.
According to court documents and statements made during proceedings, Munoz distributed cocaine, crack cocaine, and fentanyl as part of the Quiros organization.
On November 29, 2023, Munoz was arrested along with Quiros, Diaz-Rivera, and several associates after being charged with federal offenses stemming from the investigation. During these arrests, investigators executed search warrants that resulted in the seizure of approximately 700 grams of crack cocaine; over 900 vials 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, 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 pending sentencing and is scheduled to report to prison on January 16.
Quiros also pleaded guilty to related charges and received a sentence of 63 months imprisonment on August 19, 2025. Diaz-Rivera was sentenced to 210 months imprisonment on June 23, 2025.
