Where did the image of a wendigo as a rotting humanoid deer come from?

I've poked around into Native American wendigo lore, but they describe it as either some zombie like creature or a giant, rather than some rotting cervid-human hybrid. So where did that image come from?


<So where did that image come from?> From someone's imagination, just like every other supernatural claim. Humans are pretty creative when it comes to imagery. . .

Someone just made it up. That happens a lot on the internet.
