U.S. Attorney's Office, District of Massachusetts

BOSTON – A Dominican national pleaded guilty today in federal court in Boston to her role in a widespread heroin and fentanyl conspiracy.

Isis Y Lugo-Guerrero, 46, a Dominican national residing in Dorchester, pleaded guilty to conspiracy to distribute and possess with intent to distribute heroin, fentanyl, and cocaine. U.S. District Court Judge Indira Talwani scheduled sentencing for March 6, 2019. 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.

Jose Antonio Lugo-Guerrero pleaded 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. He faces a mandatory minimum sentence of 15 years and up to life in prison. He is scheduled to be sentenced on Nov. 27, 2018.

 The charge of conspiring to distribute heroin, fentanyl, and cocaine provides for a sentence of no greater than 20 years in prison, a minimum of three years and up to a lifetime of supervised release, and a fine of up to $1 million. Sentences are imposed by a federal district court judge based on the U.S. Sentencing Guidelines and other statutory factors.
