Aileen Carol Wuornos (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 the homicides of the men were committed in self-defense. Wuornos was sentenced to death for six of the murders. She was executed on October 9, 2002, by lethal injection after spending more than 10 years on Florida's death row.
