On October 8, 2002, Aileen Wuornos sat behind a sheet of glass at Florida State Prison with less than a day to live, and she had asked for it herself. She had dropped every appeal. She told the state she was ready. She had shot seven men along Florida's highways between 1989 and 1990. The newspapers called her America's first female serial killer. That same week, psychiatrists working for the governor examined her and signed off that she was perfectly sane. In the video below, the filmmaker Nick Broomfield, who had followed her case for more than ten years, sits down with her one last time. A few minutes in, you can see him realize something has gone very wrong. She wants to talk about the prison, and nothing else. She says the guards are using sonic pressure on her, pushing it into her head, trying to break her mind before they kill her. She leans so close to the glass that her breath almost touches it. Her eyes barely blink. Then she turns on all of them. The cops, the courts, the whole country. She says society railroaded her, and she says it straight into the lens, like she's talking to every person who will ever watch this tape. And then she ends the interview herself and walks away. Go back to the beginning of her life and it reads like a warning nobody listened to. Born in Michigan in 1956. Her mother left before she turned four. She grew up with grandparents in a house she later described as violent, and by her teens she was out on the road, hitchhiking the same highways where she would one day kill. Her first victim, it came out later, had served ten years in prison for rape. The jury that convicted her never heard that. The next morning, October 9, she was executed by lethal injection. She was 46. Her last words were that she was sailing with the Rock and would be back like Independence Day, with Jesus. A year later Charlize Theron played her in Monster and won the Oscar. Broomfield left that prison saying he could not understand how the woman he had just watched could be called sane. Was she a cold killer who finally cracked, or a girl the world broke long before she ever picked up a gun?
