Dominican national who was previously deported for drug offenses; used stolen ID to obtain Massachusetts Real ID, sentenced to prison

BOSTON – A Dominican national unlawfully residing in Hyde Park, Mass. was sentenced today in federal court in Boston for misuse of a Social Security number, passport fraud, aggravated identity theft and unlawfully reentering the United States after deportation.

Mariano Andujar Perez, 43, was sentenced by U.S. District Court Judge William G. Young to two years and one day in prison, to be followed by three years of supervised release. The defendant is subject to deportation upon completion of the imposed sentence. In March 2026, Andujar Perez pleaded guilty to one count of misusing a Social Security number, one count of false statement in application for passport, one count of aggravated identity theft and one count of unlawful reentry of a deported alien. Andujar Perez was indicted by a federal grand jury in December 2024.

Andujar Perez first entered the United States in 2013 and began using the identity of the victim, a U.S. citizen from Puerto Rico, to obtain identification from the Massachusetts Registry of Motor Vehicles. After being convicted in state court for drug offenses, he was removed to the Dominican Republic in 2017 and, at unknown time and place, illegally reentered the United States without permission. He resumed using the victim’s identity in 2022 and used it to obtain a Real ID and apply for a U.S. passport.

United States Attorney Leah B. Foley and Mark Comorosky, Special Agent in Charge of U.S. Department of State’s Diplomatic Security Service, Boston Field Office in Boston made the announcement. Assistant U.S. Attorneys John J. Reynolds III and Allegra K. Flamm of the Major Crimes Unit prosecuted the case.
