BOSTON — This is an official press release from the U.S. Department of Justice (USAO - Massachusetts), published as received.
BOSTON – A member of the violent Boston-based gang, H-Block, has pleaded guilty in federal court in Boston to drug conspiracy charges. Defendant is currently an inmate at a state correctional facility where he smuggled illegal drugs into the prison.
Timothy Hearns, a/k/a “King Kill,” a/k/a “Tooly,” a/k/a “Toolman,” 36, of Roxbury; pleaded guilty on Oct. 30, 2026 to conspiracy to distribute and to possess with intent to distribute PCP, MDMB-4en-PINACA and ADB-4en-PINACA. U.S. District Court Judge Indira Talwani scheduled sentencing for Feb. 2, 2027.
Hearns was one of 10 H-Block gang members and associates charged in August 2024 following a multi-year investigation of H-Block beginning in 2021 in response to an uptick in gang-related drug trafficking, shootings and violence. According to court documents, over 500 grams of cocaine, cocaine base (crack cocaine) and fentanyl, as well as over 20,000 doses of drug-laced paper were seized during the investigation.
According to the charging documents, the H-Block street gang is one of the most feared and influential city-wide gangs in Boston. Originally formed in the 1980s as the Humboldt Raiders in the Roxbury section of Boston, the gang re-emerged in the 2000s as H-Block. Current members of H-Block have a history of violent confrontation with law enforcement, including an incident in 2015 when a member shot a Boston Police officer at point blank range without warning or provocation.
Hearns is an inmate at a state correctional institution, currently serving a 19.5 to 20-year manslaughter sentence in the Massachusetts Department of Correction. Hearns was sentenced in 2014 for committing a 2010 shooting that killed a 14-year-old at the Columbus/Heath Street basketball courts, during a time when he and other members of H-Block were engaged in a violent rivalry with Heath Street gang associates. A 15-year-old boy was also shot and struck in the chest and arm but survived.
Hearns is a long-time H-Block gang member and one of three members and associates charged with conspiring to smuggle illegal drugs into a Massachusetts prison. According to court documents, the Massachusetts Department of Correction has seen a significant increase in the smuggling of synthetic cannabinoids, a/k/a “K2,” and other dangerous substances into the prison system. A common method of introducing the drugs is by exploiting the Department of Correction’s inmate mail policies, which prohibit delivery to inmates of original copies of any materials contained in incoming mail except for legal mail, original copies of which are inspected and delivered via the U.S. postal system. Sheets of paper are saturated or sprayed with liquid narcotics, dried, printed with fake legal correspondence, and then mailed to inmates in an envelope marked as legal mail, in the hope that the drug-laced paper will be delivered undetected. It is alleged that several sheets of paper containing PCP (Phenylcyclidine) and illegal K2 were seized over the course of the investigation. It is estimated that a single sheet of such paper would be worth as much as $80,000 inside the prison. Intercepted jail calls revealed that Hearns along with his co-conspirators, conspired to introduce synthetic drugs into the facilities.
Hearns is the 10th and final defendant to plead guilty in the case.
The charges of conspiracy to distribute and to possess with intent to distribute PCP, MDMB-4en-PINACA and ADB-4en-PINACA provides for a sentence of up to 20 years in prison, at least three years and up to a lifetime of supervised release and a fine of up to $1 million. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and statutes which govern the determination of a sentence in a criminal case.
