Carlos Gonzalez Nava, a 26-year-old Mexican citizen residing unlawfully in the United States, pleaded guilty on Apr. 22 in New Haven federal court to drug trafficking and firearm possession offenses, according to David X. Sullivan, United States Attorney for the District of Connecticut.
The case highlights ongoing efforts by law enforcement agencies to address drug trafficking and related crimes that affect communities across Connecticut. Authorities say Gonzalez Nava was identified as the primary recipient of parcels containing heroin and cocaine shipped from southern California to New London addresses.
Court documents show that an investigation led by the U.S. Postal Inspection Service’s Narcotics and Bulk Cash Trafficking Task Force, along with the Drug Enforcement Administration and Homeland Security Investigations, uncovered large quantities of narcotics being sent through the mail. In November 2025, officials intercepted nearly a kilogram of heroin in one parcel; another search in February 2026 revealed about 400 grams of cocaine. Upon his arrest on March 11, agents found four firearms at Gonzalez Nava’s residence.
Gonzalez Nava admitted guilt to conspiracy to possess with intent to distribute more than 100 grams of heroin and some quantity of cocaine—a charge carrying a mandatory minimum sentence of five years up to forty years—and unlawful possession of a firearm by an illegal alien, which could result in up to fifteen years’ imprisonment. He has been detained since his arrest and is scheduled for sentencing before U.S. District Judge Michael P. Shea on July 16.
This prosecution is part of the Homeland Security Task Force initiative created under Executive Order 14159: Protecting the American People Against Invasion. The task force coordinates multiple agencies—including FBI, DEA, HSI, ATF, IRS Criminal Investigation Division, Department of Labor investigators and state police—to target criminal cartels and organizations operating within or outside U.S borders.
