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

BOSTON – A Lawrence man was sentenced today in federal court in Boston for his role in a fentanyl trafficking conspiracy.

Fredis Manuel Guerrero Guzman, 28, was sentenced by U.S. District Court Chief Judge F. Dennis Saylor, IV to 21 months in prison to be followed by two years of supervised release. In March 2024, Guzman pleaded guilty to one count of conspiracy to distribute and to possess with intent to distribute 400 grams or more of fentanyl and 100 grams or more of a fentanyl analogue; one count of distribution and possession with intent to distribute 40 grams or more of fentanyl; and aiding and abetting. 

Guzman was indicted by a federal grand jury along with Melvin Antonio Perez Medina and Fraily Rodriguez Morillo in November 2022.

Between March 2022 and August 2022, Guzman, Morillo and Medina conspired to distribute and possess with intent to distribute 400 grams or more of fentanyl and 100 grams or more of a fentanyl analogue, in Lawrence, Woburn, Wilmington and Andover. Specifically, in March 2022, Guzman and Morillo met with a cooperating witness to negotiate future drug deals, including the price that Guzman would charge for fentanyl and cocaine. Thereafter, Guzman and Morillo distributed 50 grams of fentanyl to a cooperating witness in April 2022. In July 2022, Morillo and Perez Medina distributed an additional nearly 130 grams of fentanyl to a cooperating witness on one occasion, as well as over 560 grams of a fentanyl and fentanyl analogue mixture to cooperating witnesses on another occasion. 

In August 2022, Perez Medina was arrested and found in possession of nearly two kilograms of a mixture containing fentanyl and a fentanyl analogue hidden inside of a cereal box. 

On Jan. 18, 2024, Perez Medina was sentenced to 64 months in prison and three years of supervised release after previously pleading guilty to his role in the conspiracy. Morillo pleaded guilty on Feb. 12, 2024 and is scheduled to be sentenced on May 31, 2024.
