A business owner from Pelham, New Hampshire has pleaded guilty to obstructing a federal grand jury investigation involving her brother, former State Senator Dean Tran. Tuyet T. Martin, 55, entered her plea on January 21 in Boston federal court to one count of obstruction of justice. Sentencing is set for May 13, 2026 by U.S. Senior District Court Judge F. Dennis Saylor IV.
Martin and her brother were charged in June 2024 after authorities began investigating allegations that Tran fraudulently collected Pandemic Unemployment Assistance benefits and failed to report consulting and rental income on his tax returns for the years 2020 through 2022. Tran was arrested in November 2023 following a 28-count federal indictment.
The case against Martin centered on an employment offer letter she provided to Tran from her New Hampshire-based business where she served as owner and CEO. During a July 2023 grand jury session, Martin gave false testimony about the job offer letter.
According to the Department of Justice, “The charge of obstruction of justice provides for a sentence of up to 20 years in prison, three years of supervised release and a fine of $250,000.” The actual sentence will be determined by the court based on federal guidelines and statutes.
Tran pleaded guilty in December 2025 and is scheduled for sentencing on January 30, 2026.
