Seventeen northeast Texas residents have been arrested following a lengthy investigation into drug trafficking in Harrison and Marion counties. Last week, a federal grand jury returned an 839-count indictment charging the seventeen with conspiracy to manufacture Methamphetamine and possessing Pseudoephedrine with the intent to manufacture Methamphetamine. This week, local, state, and federal authorities began rounding them up.  They're accused of buying or trying to buy cold pills containing Pseudoehedrine in and around Karnack and Marshall, Texas, and here in northwest Louisiana.
