(Warwick, RI) -- Nearly a million dollars are going to the U.S. Treasury, thanks to passengers at Warwick's T.F. Green Airport. The Transportation Security Administration says the money is loose change left behind by travelers in 2017. The TSA yesterday displayed a stun gun, brass knuckles among the confiscated items this past year. The 13-hundred pounds of items will be auctioned off at a future date.
