MARYLAND — Dennis Wilson, a member of the notorious Boston-based H-Block gang, pleaded guilty to drug conspiracy charges in federal court on April 9, 2025.
Wilson, 36, of Boston, admitted to conspiring to distribute and possess controlled substances, including fentanyl, powdered cocaine, and crack cocaine.
U.S. District Court Judge Leo T. Sorokin has scheduled Wilson’s sentencing for July 8, 2025. Wilson was one of 10 individuals charged in connection with a multi-year investigation into H-Block that began in 2021.
The investigation was spurred by an increase in gang-related drug trafficking, shootings, and violence.
Over 500 grams of various drugs, as well as more than 20,000 doses of drug-laced paper, were seized during the investigation.
The H-Block gang, originally formed as the Humboldt Raiders in the 1980s in Boston’s Roxbury neighborhood, re-emerged in the 2000s under the name H-Block.
It has since become one of the most feared and influential gangs in the city.
Members of the gang have a history of violent confrontations with law enforcement, including a 2015 incident where a gang member shot a Boston Police officer at point-blank range.
From 2022 to 2023, Wilson actively participated in a conspiracy to distribute illicit drugs. He was involved in multiple drug deals with undercover officers, frequently accompanied by a co-conspirator.
As part of his guilty plea, Wilson faces a potential sentence of up to 20 years in prison, with at least three years and up to life of supervised release, and a fine of up to $1 million.
Wilson is the fourth defendant to plead guilty in the case, which remains under investigation by multiple law enforcement agencies.
The case was part of an Organized Crime Drug Enforcement Task Force (OCDETF) operation aimed at dismantling high-level criminal organizations.
United States Attorney Leah B. Foley and several law enforcement officials, including Stephen Belleau of the Drug Enforcement Administration, made the announcement. The investigation involved cooperation from the Massachusetts State Police, Boston Police, and other local agencies.
Assistant U.S. Attorney John T. Dawley and Jeremy Franker of the Justice Department are prosecuting the case. The remaining defendants are presumed innocent until proven guilty.
