It was about this time that Fish began to indulge in self-harm. He would embed needles into his groin and abdomen.[1] After his arrest, X-rays revealed that Fish had at least 29 needles lodged in his pelvic region.[1] He also hit himself repeatedly with a nail-studded paddle and inserted wool doused with lighter fluid into his anus and set it alight.[7] While he was never thought to have physically attacked or abused his children, he did encourage them and their friends to paddle his buttocks with the same nail-studded paddle he used to abuse himself. He soon developed a growing obsession with cannibalism, often preparing himself a dinner consisting solely of raw meat and sometimes serving it to his children.
