BOSTON - A Springfield man pleaded guilty in federal court in Springfield today to his role in a heroin, cocaine, and crack cocaine conspiracy. 

Oscar Rosario, 33, pleaded guilty to one count of conspiracy to distribute heroin, cocaine, and crack cocaine and two counts of distribution and possession with intent to distribute heroin, cocaine, and crack cocaine. U.S. District Court Judge William G. Young scheduled sentencing for July 31, 2019. Rosario has been in custody since his arrest on Dec. 21, 2018, when he and seven co-defendants were charged in a superseding indictment. 

According to court documents, co-defendants Nia Moore-Bush and Dinelson Dinzey obtained narcotics in the Springfield area, transported the narcotics to Vermont themselves or via couriers, and distributed the drugs in the Barre area, where drug prices are much higher than in Springfield. Rosario supplied Moore-Bush and Dinzey with heroin, including on two specific dates: Nov. 17, 2017, and Dec. 8, 2017. 

 Rosario, who has at least one prior serious conviction for a violent offense for which he served more than one year in prison, faces up to 30 years in prison, a minimum of four years of supervised release and a fine of up to $2 million. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and other statutory factors. 

United States Attorney Andrew E. Lelling and Kelly D. Brady, Special Agent in Charge of the Bureau of Alcohol, Tobacco, Firearms, and Explosives, Boston Field Division, made the announcement. Valuable assistance was provided by the Internal Revenue Service’s Criminal Investigations in Boston, the Massachusetts State Police, the Vermont State Police, the Montpelier (VT) and Barre (VT) Police Departments. Assistant U.S. Attorneys Katharine A. Wagner of Lelling’s Springfield Office and Amy Harman Burkart of Lelling’s Boston Office are prosecuting the cases.

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