Statement of Makino (18 June 1947) On being shown a picture of loshio Mori, Makino states that he first saw him standing near Komori at the liver operation, but he was at the table in the far right corner of the autopsy room across the table from Hirao when Tanaka and Makino reentered the roam.
When Tanaka and Makino arrived at the table in the far right corner, Mori and Hirao were operating on another Prisoner. There was an incision from below the sternum to a little below the navel. The incision was held open with retractors by Dr. Mori.
After Hirao finished suturing and said, "It is finished." Mori then said, "Let’s go on to the next one."
Mori made an incision over the heart and the ribs were retracted by Hirao and the heart exposed. Someone across from Mori— it might have been either. Komori or Hirao, used forceps and clamped the artery leading from the heart. Mori cut the heart sac, and, Makino believes, made a small incision in the heart itself, and Mori, Hirao and the other doctor, who Makino believes was Komori, all bent over close to the incision, talking in low voices.
When Komori came over to the table, before they started on the heart operation, he asked, "Is he dead?" Either Mori or Hinao said "Yes, he is."
After the first operation, instead of leaving the room as he has previously said, Makino walked over to the table, and it was then that he saw Hirao and Mori performing the operation on the stomach and intestines. Makino stayed there until Mori mode the incision in the chest over the heart, then walked out.
