For Immediate Release
U.S. Attorney's Office, District of Connecticut

Vanessa Roberts Avery, United States Attorney for the District of Connecticut, announced that JEAN MANGUAL-CASTRO, also known as “Mangui,” 35, of West Haven, was sentenced today by U.S. District Judge Sarala V. Nagala in Hartford to 120 months of imprisonment, followed by five years of supervised release, for trafficking cocaine.

According to court documents and statements made in court, an investigation headed by the FBI’s New Haven Safe Streets/Gang Task Force and the U.S. Postal Inspection Service’s Narcotics and Bulk Cash Trafficking Task Force revealed that Mangual-Castro was orchestrating shipments of cocaine through the U.S. Mail from Puerto Rico.  On December 20, 2021, after investigators identified a suspicious package that had been delivered to the West Haven residence of Mangual-Castro’s mother, Enid Castro, investigators conducted a court-authorized search of the residence and seized approximately two kilograms of cocaine, a Rolex watch, more than $200,000 in jewelry, and approximately $2,900 in cash.  During the investigation, law enforcement also found at another location approximately three kilograms of cocaine that had been mailed from Puerto Rico to Connecticut at Mangual-Castro’s direction.  Investigators identified numerous other suspicious parcels that had been shipped from Puerto Rico to addresses connected to Mangual-Castro in Connecticut.

Judge Nagala ordered the forfeiture of the Mangual-Castro’s interest in the watch, jewelry and cash that were seized.

Mangual-Castro has been detained since his arrest on December 20, 2021.  On September 12, 2022, he pleaded guilty to conspiracy to distribute and to possess with intent to distribute five kilograms or more of cocaine.

Enid Castro pleaded guilty to a related charge and awaits sentencing.
