8. Aileen Wuornos
Aileen Wuornos worked as a prostitute in Florida. Beyond that, though, she was part of something much more nefarious, something that went on for a whole year. By the time she was caught, she had killed six people. Her story intrigued the general public, and soon a film was made about her, entitled Monster.
In total, Wuornos shot seven men, killing six. According to her, she was just protecting herself from being sexually assaulted. But her alibi did not add up. In the end, she was found guilty and sentenced to death for her crimes. Wuornos died via lethal injection in 2002.
