The origin could be related to the human psyche's need for extreme and sensational stories. In some cultures, there are tales of monsters and inhumane acts that serve to define the boundaries of what is acceptable behavior. This story might be an extreme version of that. It could also be that in the early days of exploration, when different cultures first interacted, there were misunderstandings and rumors that got passed around. For instance, a cultural practice that was misinterpreted as cannibalism could have been the starting point for this kind of story. Additionally, the oral tradition of passing on stories from one generation to another might have led to the evolution of this particularly gruesome story as details got added or changed over time.
One possible origin could be from the misinformation or exaggeration of some rare and already disturbing historical events. Maybe there were some cases of violence or extreme behavior in the past that got distorted over time into this very extreme story. Another factor could be the human tendency to create horror stories for entertainment or to pass on warnings in a very extreme way. For example, it could be a cautionary tale that has been blown out of proportion. Also, cultural differences and misunderstandings between different groups in the past might have contributed to the creation of such a story.
