A Dominican national residing unlawfully in Lawrence, Massachusetts, has been sentenced in federal court on charges related to fentanyl distribution. Hector Santana Guzman, also known as “DJ Black,” received a sentence of 30 months in prison followed by three years of supervised release. After serving his sentence, he will face deportation proceedings.
Santana Guzman pleaded guilty in September 2025 to two counts of distributing and possessing with intent to distribute fentanyl. The investigation revealed that he sold approximately 50 grams of powder fentanyl on June 6, 2024, and about 70 grams on June 25, 2024, to a cooperating witness during an operation targeting the transnational criminal organization known as the 18th Street Gang.
The sentencing was announced by United States Attorney Leah B. Foley; Ted E. Docks, Special Agent in Charge of the Federal Bureau of Investigation’s Boston Division; and Thomas Greco, Special Agent in Charge of the Bureau of Alcohol, Tobacco, Firearms & Explosives. The Massachusetts State Police; U.S. Immigration and Customs Enforcement’s Enforcement and Removal Operations; district attorney’s offices from Suffolk and Middlesex counties; and several local police departments provided assistance with the case. Assistant U.S. Attorney Fred M. Wyshak III prosecuted the matter.
According to officials, this case is part of the Homeland Security Task Force (HSTF) initiative created under Executive Order 14159: Protecting the American People Against Invasion. The HSTF coordinates efforts across multiple government agencies to target criminal cartels, foreign gangs, transnational criminal organizations, and human smuggling operations both within the United States and abroad. Its priorities include investigating crimes involving children and prosecuting violent criminal aliens for removal from the country.
HSTF Boston consists of agents from several federal agencies—such as HSI, FBI, DEA, ATF—and state and local law enforcement partners. The prosecution is led by the United States Attorney’s Office for the District of Massachusetts.
