Wuornos had been the victim of abuse and neglect herself. Her parents split before she was born and her father, who had been arrested for child molesting, killed himself while awaiting trial in a mental institution. When her mother abandoned her at a young age, Aileen was sent to live with her grandparents. But she was kicked out of their home when she got pregnant at age 14. From 1974 to 1976, Wuornos operated under several aliases and amassed an arrest record for offenses including drunk driving, assault, and armed robbery. In 1986, she became romantically and criminally involved with a woman named Tyria Moore.

In late 1989, Wuornos began her infamous killing spree. Five months after Richard Mallory was killed, David Spears was found dead, shot six times with a .22 caliber gun in the woods near Tampa. At around the same time, another male body turned up nearby that appeared to have been killed with the same type of gun. Three additional men met the same demise during the summer of 1990.

When the seventh victim was found in November, the media was alerted to the possibility of a serial killer. After receiving several tips, detectives caught Wuornos in a seedy biker bar in January 1991. With Moore assisting police, Wuornos decided to confess to the killings but claimed that they had all been done in self-defense. When a jury found Wuornos guilty on January 27, 1992, she screamed out, “I’m innocent! I was raped! I hope you get raped! Scumbags of America!” Her outburst was probably ill considered, given the fact that the same jury came back to decide her penalty the next day. Wuornos was sentenced to death.

Also in prison she came up with the story that the police knew who was murdering these men " corruption." And that that they were gonna use her story dubbed " AMERICA'S FIRST FEMALE SERIAL KILLER " and make money off of her. Then nearing the time of her date to be executed she wanted to die. She kept telling people that she wanted right now and or if she could die tonight she would.
