5 accidentally shot at gun shows in North Carolina, Ohio, Indiana Five people were wounded in accidents at gun shows in North Carolina, Ohio and Indiana on Saturday, according to authorities. In Raleigh, N.C., authorities said three people were wounded when a loaded shotgun accidentally discharged at the Dixie Gun and Knife Show at the N.C. State Fairgrounds. Officials say Gary Lynn Wilson, 36, was having his shotgun checked before entering the show when the incident happened. He was unzipping his 12-gauge shotgun's case when it accidentally fired birdshot pellets, hitting three people, The News & Observer in Raleigh reported. "This was an accidental discharge," said Brian Long, a spokesman for the North Carolina Department of Agriculture & Consumer Services, in a statement. The Wake County Sheriff's Department is investigating Saturday's incident, and it's not clear yet whether there are pending charges, according to Long. In Medina, Ohio, an exhibitor at a local gun show was opening a box containing a gun when the weapon went off, striking his partner, who was sitting next to him, NBC station WKYC of Cleveland reported. The victim suffered non-life threatening injuries in the arm and thigh and was taken to a hospital. Police told WKYC the shooting was accidental, and a man who attended the show had sold that gun to the exhibitor. In Indianapolis, state police said a 54-year-old man was loading his .45 caliber semi-automatic gun when he shot himself in the hand, The Associated Press reported. The victim, Emory L. Cozee, had been leaving the Indy 1500 Gun and Knife show at the state fairgrounds, officials told the AP. Loaded personal weapons are not permitted inside this show, according to the AP. Cozee was hospitalized. Police told the AP no charges will be filed and the shooting was accidental. These incidents all happened on the first "National Gun Appreciation Day," which was organized by Political Media, a Republican consulting firm. Firearms expert Greg A. Danas told NBC News while it's up to a gun show owner to determine safety rules, he recommends measures like inspecting guns and ensuring firing pins are disabled. "Even people with the best intentions, screw up, occasionally make mistakes," Danas said.
