Jap Accused in Beheading of 2 Yank Flyers Singapore, Straits Settlements, March 28 (AP) – Tomono Shungo, a warrant officer of the former Japanese garrison at Saigon, was charged at a war crimes trial today with complicity in the beheading of two American flyers after a bombing attempt on the French Ind-China city last June. The slain men were Sergeants Allen W. Nicks and Joseph A. Demaria. Lt. J. W. Sands, prosecuting officers, said Nicks and Demaria were the only known survivors of a B-24 bomber that crashed. They were captured and were beheaded last July. Their bodies were rolled into graves and covered with fresh cut trees.
