Twelve people, including two from Wareham, were arrested in connection with an alleged Taunton-based heroin distribution ring Tuesday morning.

Anthony Burt, 23, and Kayla Wentworth, 24, both of Wareham, Fall River and Taunton, were arrested and charged with conspiracy to distribute heroin in connection with the drug ring.

Four Taunton residents were arrested and charged. Eddyberto Mejia Ramos, 22, aka “Chi Chi”; Luis Iraola, 21; Maria Ramos, 43; and Edwin Montalvo, 26, aka “Poncho.”

The charging documents allege that Ramos operated a retail heroin trafficking organization out of his mother’s house at 187 Winthrop St. in Taunton, and that his mother, Maria Ramos, periodically assisted her son in distributing heroin.

According to court documents, Ramos purchased large quantities of heroin from several wholesale suppliers. After receiving these large heroin packages, Ramos and his mid-level associates allegedly distributed the heroin to lower level distributors and customers, including Burt, Wentworth, Russell, and Wharf.

Also arrested and charged with conspiracy to distribute heroin were Saul Sanchez Rolon, aka “Fino,” and Kerem Mendez Luz, 35, of Providence,; Antwuun Jones, 23, of Fall River; Shakur Russell, 22, of Bridgewater; and Darius Jones, 23, of Taunton. The twelfth defendant, Jean Wharf, 40, of Carver, was arrested and charged in a related complaint with using a telephone to facilitate a drug transaction.

The arrests came as a result of a lengthy investigation, during which law enforcement officers observed Mejia Ramos sell heroin to a cooperating witness on several occasions in fall 2014 and uncovered the organizational makeup of Mejia Ramos’ organization through court authorized wiretaps from January through July of this year.

The arrests follow the July 6 - 7 arrests of Luis Guzman, 22; Mercedes Cabral, 24; and Oristel Soto-Peguero, 22, all of Norwood; and the March 16 arrest of Manuel Luis Sanquintin, 33, aka "Alex," of Boston, all in connection with the same heroin distribution ring.

United States Attorney Carmen M. Ortiz; Michael J. Ferguson, special agent in charge of the Drug Enforcement Administration, New England Field Division; Taunton Police Chief Edward J. Walsh; and Bristol County District Attorney Thomas M. Quinn made the announcement Tuesday. The case is being prosecuted by Assistant U.S. Attorney Ted Heinrich of Ortiz’s Narcotics and Money Laundering Unit.
