Aileen Wuornos (born February 29, 1956) was an American serial killer. The movie “Monster” is supposed to be based on her life. Her father, Leo Arthur Pittman, was a child molester who served time in Kansas and Michigan mental hospitals. He died by hanging while in prison in 1969. Wuornos’ mother abandoned Aileen and her brother in 1960 and left them in the care of their maternal grandparents. Wuornos claimed that her grandfather physically and sexually abused her as a child and that her grandmother was an alcoholic. She also said to have had sex with several partners upon the age of 12, including her brother Keith. Wuornos became pregnant at the age of 14 and delivered her son at a Detroit maternity home on March 23, 1971. The child was put up for adoption soon after. Wuornos began to work as a prostitute while still in school. She soon dropped out of school to work the streets full-time, earning her way as a teenage hooker and drifted across the country.In May 1974 Wuornos was jailed in Colorado for drunk driving and firing a gun from a moving vehicle. In 1976 she married 76-year-old yacht club president Lewis Gratz Fell. They were divorced six weeks later. From 1977 to 1989 Wuornos was arrested several times, used different names and made her way to Florida. Wuornos’ first victim was store owner Richard Mallory in Palm Harbor, Florida. According to Wuornos Mallory had sexually assaulted her on November 30 in 1989 after tying her to the car. She killed six more men between June 1990 and November 1990. After being identified and put in custody she made a full confession and cited self-defense for Mallory’s murder. She was convicted of his murder in January 1992. Although it was later uncovered that Mallory had served 10 years for violent rape in another state, Wuornos was never given a re-trial. Wuornos received six death sentences for the other murders. On October 9, 2002 she was executed.
