The District Attorney’s Office has dismissed an assault charge against a Creek Wood High School teacher and coach who was shot in the back during an altercation with his ex-wife’s husband. The Dickson County Grand Jury indicted Matthew R. Jones, 38, of Dickson last week on a charge of simple assault. The same grand jury voted not to indict Rodger Dale Waynick, 38, of Burns on a charge of attempted second-degree murder for shooting Jones in what police described as a domestic incident. But Assistant District Attorney Ray Crouch Jr. said he is dismissing the charge against Jones and the indictment will be expunged. “It was just too close of a call for it to be a prosecutable case,” Crouch said. The prosecutor said the district attorney’s office did not seek the indictment against Jones, who was never charged following the Oct. 31 incident at his Payne Springs Road home. Crouch said the grand jury indicted Jones “on its own accord” after hearing testimony regarding the allegations against Waynick. Police said Jones admitted throwing punches at Waynick in a disagreement over allegations of mistreatment of Jones’ children with his ex-wife, Laura Waynick, who is now married to Rodger Waynick. Jones was shot once in the lower back when Waynick pulled a .45-caliber handgun from his waistband. Police said the Jones’ two children were outside the home and witnessed the shooting.
