A Maryland federal grand jury has indicted two Bowie men on charges that they ran a heroin trafficking ring for most of the last decade.

Eric Hellams and Gregory Lewis were arrested in April on charges that they have distributed more than two pounds of heroin, the highest category of heroin trafficking charges. According to the indictment filed in Greenbelt’s federal court as well as recently unsealed court documents, the two men have bought seven Maryland properties since 2003, using profits from their heroin dealing business.
