Jap Testifies Airmen Shot SHANGHAI, (AP) – Fourteen American fliers captured at Taihoku, Formosa, in 1945 were lined up in a trench and shot down by a Japanese firing squad, Yashushi Marushima, Formosan medical officer, told an American Military Court today. His was the first eyewitness account of the execution. Marushima testified at the war crimes trial of Lt. Gen. Haruki Isayama and seven officer subordinates accused of condemning the Americans after a mock trial in which no defense counsel was provided. The prosecution charged that the court records were subsequently falsified with alleged “confessions.”
