BOSTON – A Cranston, R.I. man pleaded guilty on April 30, 2024, in federal court in Boston to his involvement in a drug trafficking organization (DTO) that distributed fentanyl throughout Southeastern Massachusetts and Rhode Island.

Mario Rafael Dominguez-Ortiz, 27, pleaded guilty to one count of conspiracy to distribute and to possess with intent to distribute fentanyl. U.S. District Court Judge Allison D. Burroughs scheduled sentencing for Aug. 6, 2024. Dominguez-Ortiz was indicted by a federal grand jury in August 2022 along with nine other individuals.

In March 2021, an investigation began into a DTO operating in Southeastern Massachusetts and Rhode Island led by Estarlin Ortiz-Alcantara. The investigation identified Dominguez-Ortiz as a member of the DTO, who was employed by Ortiz-Alcantara to deliver fentanyl. On four occasions between July and November 2021, Dominguez-Ortiz delivered fentanyl to a cooperating source. Each of the fentanyl deliveries were in amounts consistent with quantities intended for further distribution.

Dominguez-Ortiz faces a 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.

Estarlin Ortiz-Alcantara pleaded guilty in December 2023 and is scheduled to be sentenced on July 9, 2024.
