A 37-year-old man was sentenced in U.S. District Court in Hartford to 26 months in prison, followed by three years of supervised release for trafficking heroin, according to an announcement Wednesday from John H. Durham, U.S. Attorney for the District of Connecticut.

An investigation had found that Maycol Campos, a Guatemalan man living in Attleboro, Mass., had indirectly supplied a New London man, Michael Luciano, with heroin that Luciano then distributed "through a network of street-level dealers in southeastern Connecticut," according to the news release.

The announcement comes weeks after another Guatemalan man living in Central Falls, R.I., who also was involved with the network, was sentenced to 42 months in prison.

The investigation was launched following several heroin overdoses in southeastern Connecticut that included two fatalities involving a heroin and fentanyl mix in January 2016, the release stated.

In November 2017, investigators executed 12 search warrants and seized more than 3 kilograms of heroin from involved members, the release stated.

A grand jury in Hartford in December 2017 "returned a 25-count superseding indictment charging Campos, Luciano and 19 other individuals with various heroin trafficking offenses."

Both Campos and Luciano pleaded guilty in 2018 to one count of conspiracy to possess with intent to distribute 1 kilogram or more of heroin. Luciano was sentenced on Jan. 29 to 12 years of imprisonment.

Campos faces immigration proceedings when he is released from prison.

The Drug Enforcement Administration, U.S. Marshals Service, Internal Revenue Service's Criminal Investigation Division, Homeland Security Investigations, Connecticut State Police Statewide Narcotics Task Force - East and the New London, Norwich, Waterford, Attleboro, Mass., and Freetown, Mass., police departments investigated the matter. Assistant U.S. Attorneys S. Dave Vatti and Geoffrey M. Stone are prosecuting the case.
