A passenger was caught at New York's Kennedy airport with stun guns, two days after a similar case in Newark, sources said. The New York Post, citing law enforcement papers and sources, reported Tuesday Othon Mourkakos of Alpine, N.J., was stopped Sunday night as he waited for a Lufthansa flight to Frankfurt. A screener spotted the guns in a suitcase during an X-ray and hand search, a criminal complaint states. Mourkakos, a restaurant owner, said he was taking the weapons to relatives in Greece because of unrest there and did not know it was illegal, a law enforcement source said. On Friday, a stun gun was found in the back pocket of a seat on JetBlue Flight 1179 from Boston after it landed at Newark Liberty International Airport.
