Boston Man Pleads Guilty to Drug Offenses

For Immediate Release
U.S. Attorney's Office, District of Massachusetts
Defendant conspired to distribute fentanyl, heroin and cocaine that was sent in the mail

BOSTON – A Boston man pleaded guilty yesterday to his role in a conspiracy to distribute fentanyl, heroin and cocaine that had been delivered in packages to various locations, including the Harvard University campus. 

Lennon Carrasco, 38, pleaded guilty to one count of conspiracy to distribute and to possess with intent to distribute fentanyl, heroin and cocaine. U.S. District Court Judge Richard G. Stearns scheduled sentencing for June 27, 2024. Carrasco was indicted by a federal grand jury in December 2020 along with co-conspirator Dorian Rojas.

In June 2019, law enforcement recovered a FedEx package that had been delivered to a biology lab on the campus of Harvard University. The package was found to contain approximately one kilogram of fentanyl and one kilogram of cocaine. A subsequent investigation revealed that Rojas, who was a former FedEx delivery driver, asked Carrasco, who was working as a FedEx delivery driver, to retrieve the package and deliver it to Rojas. In August 2019, Carrasco was observed retrieving another package and delivering it to Rojas. Shortly after, Rojas was arrested, and the package was found to contain almost one kilogram of heroin. It was ultimately determined that Carrasco had diverted more than 20 FedEx packages for Rojas from November 2017 to June 2019.

In October 2022, Rojas was sentenced to 10 years in prison and five years of supervised release after previously pleading guilty to his role in the conspiracy. 

The charge of conspiracy to distribute fentanyl, heroin, and cocaine provides for a sentence of up to 20 years in prison, at least three years and up to life 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 statutes which govern the determination of a sentence in a criminal case.

Acting United States Attorney Joshua S. Levy; Harvard University Police Chief Victor Clay; Christine Elow, Commissioner of the Cambridge Police Department; Brian D. Boyle, Special Agent in Charge of the Drug Enforcement Administration, New England Division; and Michael J. Krol, Special Agent in Charge for Homeland Security Investigations in New England made the announcement. Assistant U.S. Attorney J. Mackenzie Duane of the Narcotics & Money Laundering Unit is prosecuting the case.

This effort is part of an Organized Crime Drug Enforcement Task Forces (OCDETF) operation.
