CANCUN, Mexico - Police are investigating the death of a Marine from Smithtown this morning.

Marine Sgt. and Army Reservist Joseph Bitet was vacationing with his girlfriend in Cancun, Mexico when he died last Saturday. Police have reportedly told his girlfriend that he had been drinking and was alone when he fell from the fifth floor of their hotel. His girlfriend says that is not true, saying she saw the hotel surveillance video showing Bitet and a man getting on and off an elevator together just before his death.

Bitet's girlfriend and family have hired a lawer to investigate. Congressman Peter King, of Seaford, is also getting involved, trying to find answers as well.
