I know, I know; the man-eater Alfred Packer oftentimes misspelled his name "Alferd," and so it came into common usage that way.
The judge's comment upon his sentencing the man-eater is a classic, where the judge berated him for having eaten three of the four known Democrats of the area.
Due to it being unconstitutional to penalize a man for a crime committed before a law was passed, the man-eater Alfred Packer couldn't be sentenced to death, only to a term in prison.
