I stumbled upon this on Wikipedia.  It’s a woman named Tura Satana.   She was an American actress and an exotic dancer.  Her famous movie is the exploitation film Faster, Pussycat!  Kill!  Kill!  However, the most fascinating detail is this:

Walking home from school just before her 10th birthday she was reportedly gang raped by five men.  According to Satana, her attackers were never prosecuted and it was rumored that the judge had been paid off.

She tells how this prompted her to learn martial arts, such as aikido and karate. Over the next 15 years, she tracked down each rapist and exacted revenge.

Now this is from Wikipedia, and this comes from Satana herself so I don’t know the veracity of this story.  However, if this is true, then Wow, we’ve got a real Kill Bill situation here.
