Japanese Doctor Admits Giving GI Fatal Injections YOKOHAMA (AP) – A principal witness in the case against five Japanese war criminal suspects completely reversed his testimony today and admitted that – as a prison camp doctor – he was ordered to kill Pvt. Everett L. Tyler of Glen Easton, W. Va. Dr. Shakichi Nosu testified before the Eighth Army Commission that he was instructed to give fatal injections of morphine to the youth, who died a few hours later in the hospital. Tyler had been recaptured after escaping from a camp at Osaka. Five defendants were charged with beating and clubbing him to death.
