Once upon a time there was a jackass.
But he was very unwise.
The jackass shot people and left assorted clues: a tarot card, lengthy notes, demands for money.
Then, through the media, he sent out this stupid reference to some obscure Native American tale, in an effort to be "cryptic" in a half-assed cat-and-mouse game.
One day the jackass was arrested in his car sleeping in a rest area.
The lesson of this story is: what a stupid jackass.
