A Suffolk man was indicted Wednesday by a federal grand jury on a charge of distribution of heroin resulting in death and other charges.

Carlos A. Brown, 45, also is charged with distribution of heroin resulting in serious bodily injury, distribution of heroin and distribution of fentanyl, according to a press release from the U.S. Attorney’s office.

According to the indictment and other filed documents, the investigation of Brown’s drug activities began in November 2015 after an investigative team was dispatched to the scene of a suspected heroin overdose death in Chesapeake.

Over the course of the next six months, members of the law enforcement team, which includes the FBI’s Norfolk Field Office, the Virginia State Police and the Chesapeake Police Department, began gathering various sources of information including confidential interviews, as well as arrest and police reports related to the alleged drug distribution activities of Brown, according to the press release.

The interviews were corroborated with undercover controlled buys of heroin and fentanyl from Brown as well as physical and electronic surveillance, according to the press release. Documents filed with the court indicate that in late November 2015, Brown contacted one buyer describing his heroin as a “missile.” Brown told one source that he was aware of three or four of his customers overdosing, yet he continued to sell heroin, which led to a fatal overdose the following day, according to the press release.

Even after learning of the fatal overdose, Brown continued to sell heroin, according to the press release.

Brown faces a mandatory minimum sentence of 20 years in prison and a maximum penalty of life in prison if convicted.
