On May 12, 1975, Khmer Rouge gunboats captured the S.S. Mayaguez in the Gulf of Thailand, approximately 60 nautical miles off the coast of Cambodia. After the vessel was taken to Koh Tang Island, U.S. aircraft began surveillance flights around the island. When efforts to secure the release of the ship and its crew failed, U.S. military forces began a rescue mission.
Three days after the Mayaguez seizure, the Air Force dispatched six helicopters to the island. One of the helicopters came under heavy enemy fire and crashed into the surf with 26 men on board. Thirteen of the men were rescued at sea, leaving Benedett and 12 other service members unaccounted-for from the crash.
Between 1991 and 2008, investigators conducted more than 10 investigations and excavations, led by Joint POW/MIA Accounting Command (JPAC). On three occasions, Cambodian authorities turned over remains believed to be those of American servicemen. In 1995, U.S. and Cambodian specialists conducted an underwater recovery of the helicopter crash site where they located remains, personal effects and aircraft debris associated with the loss. Between 2000 and 2004, all of the missing service members from this helicopter, except Benedett, were accounted-for.
On Jan. 30, 2013, Benedett was accounted-for. Scientists from JPAC and the Armed Forces Identification Laboratory (AFDIL) used circumstantial evidence and DNA process of elimination to account for his remains.
Today, more than 1,600 Americans remain unaccounted for from the Vietnam War. The U.S. government continues to work closely with the governments of Vietnam, Laos, and Cambodia to recover Americans lost during the Vietnam War.
