BOSTON –A Southbridge man pleaded guilty in federal court in Worcester to conspiring to distribute cocaine in Central Massachusetts. 

Luis Sastre Pagan, 37, of Puerto Rico and formally of Southbridge, pleaded guilty to one count of conspiring to possess with the intent to distribute 500 grams or more of cocaine. U.S. District Court Judge Margaret R. Guzman scheduled sentencing for Sept. 15, 2026. Pagan was charged in November 2024, along with co-conspirators Eric Rivera and Miguel Lopez.

From in or about April 2023 through April 2024, Sastre Pagan participated in a conspiracy that shipped kilograms of cocaine into Central Massachusetts from Puerto Rico. Evidence showed that the defendant was in communication with co-conspirators before and after the deliveries and that Sastre Pagan was directing the activity of his co-defendants and other co-conspirators as to the activity of the drug trafficking organization in and around Southbridge and Worcester. Over the course of the investigation, four packages related to the drug trafficking organization were seized, each of which were found to contain cocaine. In total, between 15-50 kilograms of cocaine is attributable to Sastre Pagan as part of his participation in the conspiracy.  

The charge of conspiring to distribute and possess with the intent to distribute controlled substances provides for a sentence of up to 20 years in prison, at least three years of supervised release and a fine of up to $1 million. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and other statutory factors. 

In August 2025, Rivera pleaded guilty to one count of conspiring to possess with the intent to distribute cocaine. In November 2025 he was sentenced to five years in prison, to be followed by three years of supervised release. In April 2026, Lopez was sentenced to six years in prison, to be followed by five years of supervised release.
