Wikipedia claims that badgers sometimes eat coyotes:
In North America, coyotes sometimes eat badgers and vice versa, but the majority of their interactions seem to be mutual or neutral. American badgers and coyotes have been seen hunting together in a cooperative fashion.

I was already familiar (and was able to find many references to) the cooperative habits of coyotes and badgers, and it doesn't seem surprising that coyotes might sometimes eat badgers. But the reverse is much more surprising, and I have been unable to find any verification for it. I've found other references to the same citation, but I haven't been able to find the citation itself.
Question: Have there really been known instances where a badger killed and/or ate a coyote?
