BOSTON – Another soldier in Boston’s brutal H-Block gang is headed to prison. Jason Bly, 44, of Quincy, received a two-year sentence and three years of supervised release on July 23, 2024, after pleading guilty to charges stemming from a large-scale drug conspiracy. The case, prosecuted by the Organized Crime & Gang Unit, highlights the ongoing battle against the city’s most dangerous crews.
Bly admitted to conspiracy to possess with intent to distribute cocaine and possession with intent to distribute the drug. Federal investigators identified him as a key supplier for H-Block, funneling wholesale quantities of cocaine into the gang’s distribution network. Court records show Bly supplied Avery Lewis, a fellow H-Block member, with a quarter kilogram of cocaine during the investigation. The bust was the result of a multi-year probe launched in 2021, triggered by a surge in gang-related drug activity, shootings, and general mayhem across Boston.
H-Block, originally known as the Humboldt Raiders in the 1980s, has a long and violent history. The gang resurfaced in the 2000s and quickly established itself as one of the most feared and influential in the city. Their reputation isn’t built on whispers; in 2015, an H-Block member brazenly shot a Boston Police officer at point-blank range, a chilling example of their disregard for law enforcement. This latest case ensnared ten H-Block members and associates, with authorities seizing over 500 grams of cocaine, crack cocaine, fentanyl, and over 20,000 doses of drug-laced paper.
This isn’t Bly’s first brush with the law. Court documents reveal a 2016 conviction for attempted assault and battery with a firearm, coupled with an illegal firearm possession charge, stemming from an incident where he allegedly fired rounds in H-Block territory. More recently, in 2024, he was convicted of assault and battery with a dangerous weapon – throwing a cup of hot coffee in another man’s face during an argument – while already on probation. The pattern of escalating violence paints a clear picture of a hardened criminal with deep ties to organized crime.
Avery Lewis, Bly’s co-defendant, received a 46-month prison sentence in June 2025. The investigation was a collaborative effort spearheaded by United States Attorney Leah B. Foley, with key contributions from the DEA, U.S. Secret Service, FBI, Department of Labor’s Office of Inspector General, and the Boston Police Department. Support also came from the Massachusetts State Police, Suffolk County District Attorney’s Office, Massachusetts Department of Corrections, and several local police departments. The case was investigated under the Organized Crime Drug Enforcement Task Forces (OCDETF), a multi-agency initiative dedicated to dismantling major criminal organizations.
Federal authorities remind the public that the details contained in charging documents are allegations, and the remaining defendants are presumed innocent until proven guilty. But for Bly, the game is over. Two years in prison is a temporary setback, but the feds are sending a message: supplying drugs for a violent gang like H-Block comes with a steep price.
