Two men were injured at an Idaho gun show Saturday morning after a vendor from Washington state accidentally fired a rifle, Ada County Sheriff's officials said. A 74-year-old man reportedly was securing a rifle with a plastic zip tie at the Lewis Clark Trader gun show near Boise when the weapon fired. The bullet went through a cardboard box, two table covers and a metal cane before striking a man holding the cane as well as a man standing nearby, officials said. Both men were hit in the leg. They were taken to a hospital with what police believed were non-life threatening injuries. Officials say the shooting happened before the show opened and it went on as scheduled/Associated Press.
