Man sentenced to 1 year and 1 day in prison for role in Southeastern Massachusetts & Rhode Island fentanyl trafficking conspiracy involving Fall River stash house

BOSTON – A Cranston, R.I. man was sentenced in federal court in Boston for his involvement in a drug trafficking organization that distributed fentanyl throughout Southeastern Massachusetts and Rhode Island.

According to the Massachusetts Department of Justice, 27-year-old Mario Rafael Dominguez-Ortiz was sentenced by U.S. District Court Judge Allison D. Burroughs to one year and a day in prison, to be followed by three years of supervised release. In May 2024, Dominguez-Ortiz pleaded guilty to one count of conspiracy to distribute and to possess with intent to distribute fentanyl. 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. The total amount of fentanyl that the defendant distributed over the fourth-month period was approximately 500 grams.

Estarlin Ortiz-Alcantara pleaded guilty in December 2023 and is scheduled to be sentenced on Feb. 5, 2025.

According to the charging documents, intercepted communications on numerous cellphones allegedly identified Mario Rafael Dominguez-Ortiz, Yeury Francisco Garcia-Rodriguez, Rafael Cesar Cabreja Jimenez and Alfredo Rodriguez as members of the DTO who conspired with Ortiz-Alcantara to regularly distribute multi-kilograms of fentanyl from a base of operations at a stash house in Fall River. According to court documents, at the time of their arrest, Cabreja Jimenez and Rodriguez had barricaded themselves in a back bedroom of the stash house upon the arrival of law enforcement.

The investigation also identified Rebecca Bartholomew, Edwin Collazo, Jason Cruz, Michael Pacheco and Jose Santiago as alleged regular DTO customers who re-distributed fentanyl to their own local customer bases in areas including Cape Cod and New Bedford. As part of the conspiracy, it is alleged that members of the DTO, under Ortiz-Alcantara’s management and control, conducted drug transactions with these regular customers in public areas – including in the diaper aisle of a store and in supermarket parking lots. It is also alleged that on at least one occasion, members of the DTO transported drugs concealed in cereal boxes while accompanied by a child. Over 500 grams of suspected fentanyl was seized during the investigation through controlled purchases and drug seizures.
