Woburn Man Sentenced to 10 Months in Prison for Bank Fraud and Money Laundering

BOSTON - A Woburn man was sentenced yesterday in federal court in Boston for the theft of U.S. Treasury tax refund checks in Massachusetts.

Nnamdi Opara, 31, was sentenced by U.S. District Court Chief Judge Denise J. Casper to 10 months in prison, to be followed by two years of supervised release. Opara pleaded guilty in November 2025. In September 2025, Opara was charged with two counts of bank fraud and five counts of money laundering. The defendant was previously arrested in June 2025 as part of an investigation into the theft of U.S. Treasury tax refund checks in Massachusetts.

Opara wrongfully obtained two U.S. Treasury checks that were issued to a New York entity named AFGO Mechanical Services, Inc. After obtaining the checks, Opara established a company called AFGO Mechanical Services, Inc. in Massachusetts, for which he served as the President, Treasurer, Secretary, Vice President, Director and Registered Agent. Opara then deposited the U.S. Treasury check into an account he controlled, payable to the Massachusetts-based AFGO entity he had established when, in fact, the Massachusetts-based AFGO entity had never filed a federal tax return. As a result, Opara stole a total of $700,767 from the U.S. Treasury. In addition, Opara conducted multiple illegal monetary transactions designed to conceal the source of the funds from the stolen Treasury checks.

United States Attorney Leah B. Foley; Thomas Demeo, Special Agent in Charge of the Internal Revenue Service Criminal Investigation, Boston Field Office; and Jason Buckley, Acting Inspector in Charge of the U.S. Postal Inspection Service's Boston Division made the announcement today. Assistant U.S. Attorney Brian Sullivan of the Criminal Division prosecuted the case.
