Dominican national sentenced in heroin, fentanyl ring that reached to Fall River, Taunton, New Bedford

BOSTON – A Dominican national was sentenced yesterday in federal court in Boston for her role in a widespread heroin and fentanyl conspiracy. The defendant had previously failed to appear for trial after being released on unsecured bond.

Isis Y Lugo-Guerrero, 46, a Dominican national residing in Dorchester, was sentenced by U.S. District Court Judge Indira Talwani to two years in prison and three years of supervised release. Lugo-Guerrero will be subject to deportation upon completion of her sentence. In November 2018, Lugo-Guerrero pleaded guilty to conspiracy to distribute and possess with intent to distribute heroin, fentanyl and cocaine.

Lugo-Guerrero was arrested on Feb. 14, 2017, and released from custody on March 2, 2017, on $10,000 unsecured bond. The first day of her week-long trial was scheduled to begin on Sept. 10, 2018, but she failed to appear in court, and a warrant was issued for her arrest. She was arrested on Oct. 3, 2018.

Lugo-Guerrero is the sister of Jose Antonio Lugo-Guerrero, the convicted leader of a Boston-based heroin and fentanyl trafficking organization. Isis Lugo-Guerrero conspired with her brother and others by regularly obtaining heroin and cocaine from him and by supplying him with substances to cut his drugs to make additional profit.

In December 2018, Jose Antonio Lugo-Guerrero was sentenced to 16 years in federal prison after pleading guilty to one count of conspiracy to distribute and possess with intent to distribute more than one kilogram of heroin, more than 400 grams of fentanyl, and more than five kilograms of cocaine, and one count of possession of a firearm in furtherance of a drug trafficking crime.
