The U.S. Attorney for the Eastern District of Oklahoma said a grand jury handed down indictments for 12 people living in and around the Adair County area.
Prosecutors said the group trafficked meth from eastern Oklahoma and distributed all over the region, including Oklahoma City. The indictment said the meth dealers even traveled to local casinos to gamble off and convert their drug money into legitimate winnings.
Agents also recovered more than a dozen guns.
Officials said the arrests will have a huge impact on crime in the area.
