Aileen Carol Wuornos (/ˈwɔːrnoʊs/; born Pittman; February 29, 1956 – October 9, 2002) was an American serial killer. In 1989–1990, while engaging in street prostitution along highways in Florida, she shot dead and robbed seven of her male clients. Wuornos claimed that her clients had either raped or attempted to rape her, and that all of the homicides were committed in self-defense. Wuornos was sentenced to death for six of the murders and on October 9, 2002, after 12 years on Florida's death row, was executed by lethal injection.
