The stuff you find out trolling Wikipedia's "on this day" list: Introducing Sada Abe, who:

... is remembered for erotically asphyxiating her lover, Kichizo Ishida (石田 吉蔵 Ishida Kichizō?), on May 18, 1936, and then cutting off his penis and testicles and carrying them around with her in her handbag.

There's bound to be at least a short story in there, but I'm not gonna be the one to write it.
