Taunton Woman Sentenced for Distributing Heroin and Fentanyl

BOSTON – A Taunton woman was sentenced today in federal court in Boston for her role in a heroin and fentanyl trafficking organization that operated in Taunton and Boston.

Stephanie O’Sullivan, 31, was sentenced by U.S. District Court Judge Leo T. Sorokin to time served (two and a half months) and three years of supervised release. In October 2017, O’Sullivan pleaded guilty to one count of conspiracy to distribute and possess with intent to distribute heroin and fentanyl. In February 2017, O’Sullivan was arrested and charged with approximately 20 co-defendants.  

From mid-2016 through February 2017, federal law enforcement investigated two heroin and fentanyl trafficking organizations allegedly operating in Boston, led by Jose Antonio Lugo-Guerrero, and in Taunton, led by Fernando Hernandez. Hernandez’ organization sold heroin and fentanyl to customers, including O’Sullivan, who re-distributed a portion of the drugs she obtained. It is alleged that Hernandez obtained drugs from a network of suppliers that included Lugo-Guerrero.

Hernandez pleaded guilty and on Feb. 26, 2018, was sentenced to 188 months in prison.  Lugo-Guerrero pleaded not guilty and is awaiting trial.

United States Attorney Andrew E. Lelling; Michael Ferguson, Special Agent in Charge of the Drug Enforcement Administration, Boston Field Division; Colonel Kerry A. Gilpin, Superintendent of the Massachusetts State Police; Fall River Police Chief Daniel S. Racine; New Bedford Police Chief Joseph C. Cordeiro; Taunton Police Chief Edward James Walsh; Boston Police Commissioner William B. Evans; and Bristol Country District Attorney Thomas M. Quinn made the announcement today. Assistant U.S. Attorney Theodore B. Heinrich of Lelling’s Narcotics and Money Laundering Unit prosecuted the case.

The details contained in the charging documents are allegations. The remaining defendants are presumed innocent unless and until proven guilty beyond a reasonable doubt in a court of law.
