Between late 1989 and 1990, seven men were shot and killed along the highways of northern and central Florida in a series of murders later attributed to Aileen Carol Wuornos, a woman who supported herself through sex work solicited along interstate roadways. The victims were Richard Charles Mallory, a 51-year-old electronics store owner and her first victim, killed in late November 1989; David Andrew Spears, a construction worker; Charles Edmund Carskaddon, a rodeo worker; Peter Abraham Siems, a retired merchant seaman whose body was never recovered; Troy Eugene Burress, a sausage salesman; Charles Richard 'Dick' Humphreys, a retired Air Force major and former police officer; and Walter Gino Antonio, a trucker and security guard. Each man was shot multiple times, and each was robbed; several were left in wooded areas off Florida roadways.

Wuornos consistently maintained during her first trial that the men had raped or attempted to rape her and that the killings were acts of self-defense. In later statements, according to reporting and court records, she abandoned that account and described the killings as robberies in which she eliminated witnesses, at one point stating that she had killed and robbed the men. The shift between these accounts became a central point of contention in her case and in subsequent public debate. This narrative presents both her self-defense claims and the later statements as reported and attributed, rather than as adjudicated fact.

The investigation gained momentum in July 1990 after Siems's car was found abandoned and wrecked in Orange Springs, Florida; witnesses described two women leaving the vehicle. Investigators linked Wuornos to the crimes through fingerprints recovered from the car and from items pawned under her name. She was arrested on January 9, 1991, at a biker bar in Volusia County. Her former partner, Tyria Moore, cooperated with police, and Wuornos confessed on January 16, 1991, again framing the deaths as self-defense.

Wuornos went to trial for Mallory's murder on January 14, 1992, was convicted on January 27, and was sentenced to death on January 31. She subsequently pleaded guilty or no contest to additional killings and ultimately received six death sentences. She spent more than a decade on Florida's death row. On October 9, 2002, after dropping her appeals and being found competent to be executed, Wuornos was put to death by lethal injection at Florida State Prison near Starke at 9:47 a.m.

Wuornos's case drew intense attention to questions about her mental state and her background. Defense experts reported diagnoses including borderline and antisocial personality disorder, and accounts of her early life described severe abuse and exploitation in childhood; supporters argued these factors, and her account of violence by clients, complicated a simple 'monster' narrative, while prosecutors emphasized the robberies. These interpretations remain debated and are attributed to the parties and experts who advanced them. Her story reached a wide audience through the 2003 film 'Monster,' in which Charlize Theron won the Academy Award for Best Actress for her portrayal of Wuornos, and through multiple documentaries. Her convictions and 2002 execution are established matters of record.
