Aileen Carol Wuornos Pralle (; born Aileen Carol Pittman; February 29, 1956 – October 9, 2002) was an American serial killer who murdered seven men in Florida between 1989 and 1990 by shooting them at point-blank range. Wuornos claimed that her victims had either raped or attempted to rape her while she was working as a prostitute, and that all of the homicides were committed in self-defense. She was convicted and sentenced to death for six of the murders and was executed by lethal injection on October 9, 2002.
The 2003 film Monster chronicles Wuornos' story from childhood until her first murder conviction. It stars Charlize Theron as Wuornos, a performance that earned Theron an Academy Award for Best Actress.
