The indictment returned Tuesday charges Koontz, Macropoulos, Nowland, and Humphrey with conspiring to defraud the U.S. The Indictment charges the defendants with keeping miners underground and continuing to mine coal for all or portions of three shifts while unsuccessfully fighting a fire. Nowland and Humphrey are also charged under the Mine Act with falsification of records required to document mine hazards. Koontz and Macropoulos are charged with obstruction of an MSHA proceeding for entering the mine in violation of an MSHA safety order withdrawing miners from the mine. Members of the conspiracy, including Koontz, Macropoulos, and Parsons, are alleged to have then gone underground to continue their attempts to fight the fire.
