Enligt egna uppgifter utförde Josef Mengele medicinska experiment på Ganon och tog utan bedövning ut Ganons ena njure:
- "Ganon had to lie down on a table and was tied down. Without any anesthetics, Mengele cut him open and removed his kidney. "I saw the kidney pulsing in his hand and cried like a crazy man," Ganon says. "I screamed the 'Shema Yisrael.' I begged for death, to stop the suffering.""
