While sitting in his truck, McElroy was shot at several times but hit only twice—once by a centerfire bullet and once by a .22 rimfire bullet. In all, there were 46 potential witnesses to the shooting, including Trena McElroy, who was in the truck with her husband when he was shot. Nobody called for an ambulance. Only Trena claimed to identify a gunman; every other witness was either unable to name an assailant or claimed not to have seen who fired the fatal shots. The DA declined to press charges, and an extensive federal investigation did not lead to any charges either. Missouri-based journalist Steve Booher described the attitude of some townspeople as "he needed killing."
