Keenan A. Draughon, 23, of Clarksville, Tenn., was arrested at Kennedy International Airport in New York on Saturday when officers discovered a shotgun, two pistols and two rifles as he was checking in for his flight to Charlotte, N.C. Draughon approached a United Airlines counter and told an attendant that he had two cases containing firearms—two 9-millimeter pistols, two magazines capable of holding 15 rounds of 9-millimeter ammunition, and two .22-caliber rifles. The rifles had been painted purple and silver, and one of them had a round in the chamber. Both were missing serial numbers.

Mr. Draughon’s father, Kevin, said his son joined the Army when he was 19 and was an avid hunter. Gun owners are subject to arrest if they are caught with weapons at New York City airports when they try to check them for outbound flights. “Before leaving home, passengers should acquaint themselves with the weapon laws of the jurisdiction that they are visiting,” said Richard A. Brown, the Queens district attorney.

Here is today’s report.
