Based upon his date of death as it is stated by the ABMC 9/7/44 , there is a high probability that he died aboard the Japanese hellship Shinyo Maru . It was on its way from the Philippines to Japan . On 7 September 1944, A US Submarine the USS Paddle sunk the Shinyo Maru off Mindanao . Of the 750 Americans who began the voyage, only 82 survived .
Almost every POW I have ever researched who died on that date, died on that ship.
