Luis Alfonso Mejia-Diaz, Cocaine and Fentanyl Conspiracy, Massachusetts 2023

A Dominican man was sentenced in federal court in Boston for his role in a large-scale fentanyl and cocaine distribution operation that trafficked narcotics throughout southeastern Massachusetts, Rhode Island and Connecticut.

Luis Alfonso Mejia-Diaz, aka “El Bello,” 56, was sentenced by U.S. District Court Judge William G. Young to 13 years in prison and five years of supervised release.

Mejia-Diaz pleaded guilty on April 5, 2023, to conspiracy to distribute and to possess with intent to distribute 400 grams or more of fentanyl and 500 grams or more of cocaine.

Mejia-Diaz was charged in October 2020, along with 14 others. The investigation, which began in March 2017, identified Mejia-Diaz as a large-scale fentanyl and cocaine distributor who operated under his alias, El Bello, and served as a supply source for others in the conspiracy.

During the investigation, 991 grams of fentanyl intended for Mejia-Diaz were seized. At the time of his arrest in October 2020, over a kilogram of fentanyl and a loaded firearm from a hidden compartment inside an air compressor in Mejia-Diaz’s residence were also seized in addition to a kilogram press from on top of the air compressor.

Mejia-Diaz is the 13th defendant to be sentenced in the case.

The operation was conducted by a multi-agency task force through the Organized Crime Drug Enforcement Task Force (OCDETF), a partnership between federal, state and local law enforcement agencies.
