A Boston man identified as a member of the Mission Hill gang was sentenced on federal charges involving firearms trafficking, bank fraud, and a mail theft scheme that resulted in significant financial losses.
Glenroy Miller, also known as “Trinny,” age 29, received a sentence of 71 months in prison and three years of supervised release. U.S. District Court Judge Nathaniel M. Gorton handed down the sentence after Miller pleaded guilty to several charges, including being a felon in possession of firearms and ammunition, unlawful possession of a machinegun, firearms trafficking, conspiracy to commit bank fraud, aiding and abetting bank fraud, and conspiracy to steal and possess stolen mail.
Court records show that Miller had previously been convicted in September 2019 on state firearm offenses and resisting arrest. He began serving his state sentence later that year but soon conspired with Nadaje Hendrix—then an employee at a credit union—to obtain fraudulent loans using stolen identities and information from fellow inmates. Between December 2019 and August 2021, they defrauded the credit union out of about $134,000. Both were indicted by a federal grand jury in January 2024; Hendrix received an eight-month prison sentence followed by supervised release.
After being released from state prison in summer 2023 and while still on probation, Miller became involved with other Mission Hill gang members in a check theft operation often referred to as “card cracking.” This method typically involves stealing checks from postal boxes, chemically washing them to remove payee details, rewriting them for deposit into accounts controlled by recruited individuals—often contacted via social media—and quickly withdrawing or transferring funds before detection. According to investigators, between June 2023 and February 2024 Miller’s activities led to losses or attempted losses estimated between $250,000 and $550,000 through this scheme.
Miller was indicted along with eight others for their alleged roles in these crimes in August 2024.
During this period on probation in summer 2023, Miller also sold six firearms—including one equipped with a machinegun conversion device—to an individual he knew was legally barred from possessing guns.
United States Attorney Leah B. Foley announced the sentencing along with officials from the FBI’s Boston Division; Bureau of Alcohol, Tobacco, Firearms & Explosives; United States Postal Inspection Service; U.S. Secret Service; as well as support from local police departments. Assistant U.S. Attorneys Kriss Basil, Lucy Sun and Philip C. Cheng prosecuted the case.
The investigation was conducted under the Organized Crime Drug Enforcement Task Forces (OCDETF), which targets major criminal organizations through multi-agency collaboration led by prosecutors using intelligence-driven strategies. More information is available at https://www.justice.gov/OCDETF.
