(KCCR) — A Pierre man has been indicted by a federal grand jury on federal drug and firearms charges. U-S Attorney for South Dakota Ron Parsons says indictments were handed down November 13th against 34 year-old Dustin Warnke for Conspiracy to Distribute a Controlled Substance and Possession of a Firearm by a Prohibited Person. Warnke pleaded not guilty to the indictment before U-S Magistrate Judge Mark Moreno on Tuesday. The Indictment alleges Warnke knowingly conspired with others to distribute and possess with intent to distribute 500 grams or more of methamphetamine. Additionally on January 5th of this year, Warnke had been in possession of a 40-caliber semi-automatic handgun while being an unlawful user of a controlled substance. Parsons says drug trafficking is a dangerous activity and that is common to find firearms as tools of the trade for drug dealers. If convicted of the charges, Warnke would face at least 10 years in federal prison and up to life with at least five years of probation and or a 10-million dollar fine. Warnke is in the custody of the U-S Marshals Service pending a trial. A trial date has not been set.
