A member of the Mission Hill gang in Boston has admitted guilt to a range of federal charges, including firearm trafficking, credit union fraud exceeding $130,000, and involvement in a large-scale mail theft scheme known as "card cracking," which resulted in losses estimated between $250,000 and $550,000.
Glenroy Miller, also known as "Trinny," aged 28, pleaded guilty on May 9, 2025. He faced multiple charges: three counts of being a felon in possession of firearms and ammunition; unlawful possession of a machinegun; trafficking firearms; conspiracy to commit bank fraud; bank fraud with aiding and abetting; and conspiracy to steal and possess stolen mail. U.S. District Court Judge Nathaniel M. Gorton set the sentencing for August 7, 2025.
Miller's criminal activities date back to September 2019 when he was convicted for firearm-related offenses in Suffolk Superior Court. Following his conviction, he began serving a state prison sentence during which he conspired with Nadaje Hendrix to defraud a credit union where Hendrix worked as a loan officer. Between December 2019 and August 2021, they secured loans using stolen identities or names of other individuals, including fellow inmates of Miller. Their actions led to approximately $134,000 being taken from the credit union. Hendrix received an eight-month prison sentence after pleading guilty in July 2024.
After his release from state prison in summer 2023 but before his January 2024 indictment, Miller joined forces with other gang members for a mail theft operation while on probation. This scheme involved stealing checks from USPS collection boxes and altering them chemically before depositing them into recruited accounts for withdrawal or transfer.
During this period, Miller sold six firearms illegally on four occasions between August and October 2023 to an individual who was cooperating with law enforcement despite knowing the buyer was prohibited from owning guns due to prior convictions.
The potential penalties for Miller's charges are severe: up to fifteen years imprisonment each for firearm possession and trafficking offenses; ten years for unlawful machinegun possession; thirty years each for bank fraud-related crimes; five years for mail theft conspiracy—all accompanied by possible fines ranging from $250,000 to $1 million.
U.S. Attorney Leah B. Foley announced these developments alongside officials from various federal agencies involved in the investigation: FBI Boston Division Acting Special Agent James Crowley; ATF Boston Field Division Special Agent James M. Ferguson; U.S Postal Inspection Service Inspector Ketty Larco-Ward; U.S Secret Service Boston Field Office Special Agent Randy Maloney—with support from local police departments.
The Organized Crime Drug Enforcement Task Forces (OCDETF) played a key role in investigating this case through its collaborative approach aimed at dismantling high-level criminal organizations across America.
