There have been many female serial killers throughout history, but some of the most well-known include:
Aileen Wuornos
Aileen Wuornos was an American serial killer who murdered seven men in Florida between 1989 and 1990. She claimed that she killed them in self-defense after they attempted to rape her, but she was convicted of all seven murders and sentenced to death. Wuornos was executed by lethal injection in 2002.
Belle Gunness
Belle Gunness was a Norwegian-American serial killer who operated a "lonely hearts" scheme in the early 20th century. She lured men to her farm in Indiana, where she killed them and collected their life insurance money. Gunness is estimated to have killed between 14 and 40 people, and her true identity and whereabouts remain a mystery.
Lizzie Borden
Lizzie Borden was a young woman who was accused of murdering her father and stepmother in their home in Fall River, Massachusetts, in 1892. Although she was acquitted of the crime, she remained a suspect and her story has become a popular part of American folklore.
Jane Toppan
Jane Toppan was an American serial killer who worked as a nurse in the late 19th and early 20th centuries. She admitted to killing 31 patients, but her actual victim count may be much higher. Toppan was known for experimenting with different poisons on her patients and for taking pleasure in their suffering.
These are just a few examples of female serial killers. Many other women have been convicted of murder, and the motivations behind their crimes vary widely.
