A Dominican national has pleaded guilty in federal court in Boston to conspiring to possess and distribute controlled substances. Eduardo Morales-Perez, also known as “Yenni Rafael Guerrero Aybar,” 41, entered the plea on September 2, 2025. U.S. District Judge Nathaniel M. Gorton scheduled sentencing for October 8, 2025.
According to authorities, the investigation began in March 2018 with an undercover cash pickup arranged as part of a money laundering probe. An individual arrived at the meeting location and provided $275,090 in cash to undercover law enforcement officers while driving a white Volvo registered to Morales-Perez’s girlfriend.
After this transaction, law enforcement observed the vehicle at a property in Peabody. In May 2018, during surveillance at that location, Morales-Perez was seen leaving a truck carrying acetone—a chemical commonly used in producing fentanyl analogues—into the residence. A search of the property later that month led to the discovery of one kilogram pill press; drug distribution paraphernalia; over 2.8 kilograms of fentanyl and fentanyl analogues; more than five kilograms of ANPP (a substance often used in making fentanyl); and $130,000 in cash packaged similarly to that from the earlier transaction. The drugs and money were hidden above a light fixture.
The charge carries a potential sentence of up to 20 years in prison, supervised release ranging from three years up to life, and a fine up to $1 million. Morales-Perez is subject to deportation after serving any imposed sentence. Sentences are determined by federal judges according to established guidelines and statutes.
“United States Attorney Leah B. Foley and Jarod A. Forget, Special Agent in Charge of the Drug Enforcement Administration, New England Field Division made the announcement today. Valuable assistance was provided by the Massachusetts State Police and the Medford, Peabody and Ipswich Police Departments. Assistant U.S. Attorneys Lauren A. Graber and Brian J. Sullivan of the Narcotics & Money Laundering Unit are prosecuting the case.”
