A business owner from New Hampshire has admitted to obstructing a federal grand jury investigation related to her brother, former State Senator Dean Tran. Tuyet T. Martin, 55, of Pelham, New Hampshire, pleaded guilty on January 21 in federal court in Boston to one count of obstruction of justice. U.S. Senior District Court Judge F. Dennis Saylor IV set her sentencing for May 13, 2026.
Martin and her brother were both charged in June 2024 as part of an investigation into Tran’s alleged fraudulent collection of Pandemic Unemployment Assistance benefits and his failure to report consulting and rental income on his tax returns for the years 2020 through 2022. Tran was arrested in November 2023 following a federal indictment with 28 counts.
The investigation also looked into a job offer letter Martin provided to Tran at her New Hampshire-based company where she serves as owner and CEO. During a grand jury session in July 2023, Martin gave false testimony about the employment offer letter.
The obstruction charge carries a potential sentence of up to 20 years in prison, three years of supervised release, and a fine that could reach $250,000. Sentencing will be determined by the federal district court judge according to U.S. Sentencing Guidelines and relevant statutes.
Tran entered a guilty plea in December 2025 and is scheduled for sentencing on January 30, 2026.
