From the Smithsonian.com by Eliza McGraw:
On July 20, 1889, in a gulch by the Wyoming’s Sweetwater River, six cattlemen lynched a man and a woman accused of cattle rustling. As the purported bodies twisted from the same tree limb: a rider galloped toward the town of Rawlins with the news: cattlemen had exacted revenge on two ruthless thieves, Jim Averell and Ella Watson, the woman they called Cattle Kate.
The story was shocking—it echoed across America like a shot, and only grew more dramatic in the retelling. One newspaper headline read: “Blaspheming Border Beauty Barbarously Boosted Branchward.”
