Duanne Ammann, 60, owner of a convenience store, was filling a cooler with drinks around 6 p.m. when brothers Quinten Felton, 17, and Eddie Felton, 20, entered the store. Both men were wearing bandannas and ski masks. Eddie was carrying a rifle. With the barrel of the rifle pointed at his face, Ammann was ordered to open the cash register. He was then knocked to the floor where Quinten began to violently kick the store owner. During the struggle, Ammann was able to reach the handgun he kept under the store counter. He fired once hitting Quinten in the abdomen. Ammann fired three more rounds in Eddie’s direction, who still had the rifle pointed at him. They fled, but the bodies of both men were later found nearby. Ammann was treated for his injuries and released from the hospital. (The Daily Advance, Hobbsville, NC, 5/24/12)

June 1988: Miami, Fla., cabdriver Mark Yuhr had just delivered his fare when the passenger pulled out a pistol and screamed demands for money. Instead, as the robber looked away momentarily, Yuhr, who was recently licensed for concealed carry under a new Florida law, reached for his own .45 and opened fire, killing his assailant. The man had an extensive criminal record that included armed robbery, firearm violations and the attempted first-degree murder of a police officer. Police said, "This sends a major message to the rest of the robbers out there." (The Herald, Miami, Fla.)
