Windigo

A windigo is an Indian who has eaten, or who (perhaps a poor lunatic) says he wants to eat, human flesh. At Sturgeon Lake (Bishop Clut tells us), among the Indians uninfluenced by religion, there were some supposed windigos. A sudden fear of them seized upon the other Indians, and they executed one windigo. The important point in such a case was to make the cannibal vomit up the ice which he was supposed to have in his inside.

"Windigo psychosis" has been the most celebrated culture trait of the Northern Algonkian peoples for almost half a century. […] The conclusion reached is that, although aspects of the windigo belief complex may have been "components in some individuals' psychological dysfunction" (Preston 1980: 128), there probably never were any windigo psychotics in the sense that cannibalism or murder was committed to satisfy an obsessional craving for human flesh. It is argued, rather that windigo psychosis as an etic/behavioral form of anthropophagy is an artifact of research conducted with an emic/mental bias.

The Windigo is a flesh-eating, wintry demon with a man buried deep inside of it. In some Chippewa stories, a young girl vanquishes this monster by forcing boiling lard down its throat, thereby releasing the human at the core of ice.

The noun windigo [Ojibwa wīntikō, Cree wīhtikōw] refers to one of a class of anthropophagous monsters, “supernatural” from a non-Algonquian perspective, who exhibit grotesque physical and behavioral abnormalities and possess great spiritual and physical power.
