U.S. Attorney John Bales announced on Monday the indictments, which were handed down last month by a federal grand jury, were the result of a 10-month, multi-agency investigation in the Gregg County area.

The defendants are charged with conspiring to distribute methamphetamine and cocaine from at least January 2014.

Many of those indicted are also charged with firearms violations such as being felons in possession of a firearm and possession of a firearm during a drug trafficking crime.
