Former NAU student Steven Jones has hired a new lawyer. At a hearing Tuesday at the Coconino County Courthouse, Jones told the court Phoenix attorney Christopher Dupont will be leading his defense council in his retrial. The move comes after his last attorneys, Ryan Stevens and Bruce Griffin, removed themselves from the case after having prior contact with one of the victims. Jones has been charged with first degree murder and aggravated assault in connection with the shooting of four NAU students in March of 2015. The shooting took the life of student Colin Brough. Jones admitted to shooting the four, but claims it was in self-defense. The last trial ended in a hung jury back in April of 2016. The retrial was set to begin this past Tuesday, however a new trial date is expected to be set soon.
