At the trial, a Japanese witness for the prosecution asserted that Girard had yelled a warning to Sakai before firing, but Girard himself denied ever having done so, a statement which shocked and mystified observers.[4] According to testimony from Victor Nickel, a soldier of the same rank who had accompanied him, Girard had lured Sakai and other scavengers toward his position by tossing empty casings out onto the range, then fired at Sakai "for a joke".[4] Girard claimed that the death had been an accident.[3] The presiding judge, Yuzo Kawachi, went so far as to visit the scene of the incident himself, and pronounced himself "baffled" by the discrepancies in Girard's account of events.
