A dataset of 73 variables was complied on 345 serial killers, 31 of whom who engaged in cannibalism. A distinction was made between those who engaged only in cannibalism, those who engaged in necrophilia, and those who engaged in both or neither. Those who engaged in both cannibalism and necrophilia were the most psychiatrically disturbed and deviant, but those who engaged in only cannibalism were more disturbed and deviant in their actions than those who engaged in neither behavior.
