A specimen of folk story collected in the early 20th century by Lottie Chicogquaw Marsden, an ethnographer of the Chippewas of Rama First Nation, in which a wendigo also exhibits tool use, an ability to survive partial dismemberment, and autocannibalism, reads:One time long ago a big Windigo stole an Indian boy, but the boy was too thin, so the Windigo didnt eat him up right away, but he travelled with the Indian boy waiting for him till hed get fat. The Windigo had a knife and hed cut the boy on the hand to see if he was fat enough to eat, but the boy didnt get fat. They travelled too much. One day they came to an Indian village and the Windigo sent the boy to the Indian village to get some things for him to eat. He just gave the boy so much time to go there and back. The boy told the Indians that the Windigo was near them, and showed them his hand where the Windigo cut him to see if he was fat enough to eat. They heard the Windigo calling the boy. He said to the boy "Hurry up. Dont tell lies to those Indians." All of these Indians went to where the Windigo was and cut off his legs. They went back again to see if he was dead. He wasnt dead. He was eating the juice (marrow) from the inside of the bones of his legs that were cut off.
In 1661, The Jesuit Relations reported:

Although in many recorded cases of Wendigo psychosis the individual has been killed to prevent cannibalism from resulting, some Cree folklore recommends treatment by ingestion of fatty animal meats or drinking animal grease; those treated may sometimes vomit ice as part of the curing process.One of the more famous cases of Wendigo psychosis reported involved a Plains Cree trapper from Alberta, named Swift Runner. During the winter of 1878, Swift Runner and his family were starving, and his eldest son died. Twenty-five miles away from emergency food supplies at a Hudsons Bay Company post, Swift Runner butchered and ate his wife and five remaining children. Given that he resorted to cannibalism so near to food supplies, and that he killed and consumed the remains of all those present, it was revealed that Swift Runners was not a case of pure cannibalism as a last resort to avoid starvation, but rather of a man with Wendigo psychosis. He eventually confessed and was executed by authorities at Fort Saskatchewan.Another well-known case involving Wendigo psychosis was that of Jack Fiddler, an Oji-Cree chief and medicine man known for his powers at defeating wendigos. In some cases, this entailed killing people with Wendigo psychosis. As a result, in 1907, Fiddler and his brother Joseph were arrested by the Canadian authorities for homicide. Jack committed suicide, but Joseph was tried and sentenced to life in prison.
