Fast Facts

How Many People Did Aileen Wuornos Kill? The Crimes and Victims

Wuornos killed male clients along Florida highways in 1989 and 1990. She initially said the men raped or attempted to rape her and that she acted in self-defense, but later abandoned that defense. Some sources say she killed six men; others say seven men and note that she was convicted for six murders, which reflects the common distinction between the number killed and the number convicted.

List of Known Victims

The seven men widely attributed to Wuornos include Richard Mallory, David Spears, Charles Carskaddon, Troy Burress, Dick Humphreys, Walter Jeno Antonio, and Peter Siems. She was convicted for six of these murders; the killing of Peter Siems was not prosecuted due to the lack of a body.

Modus Operandi

Wuornos would approach men as a sex worker along highways such as I-75, I-95, and US-19 in Florida. She used a firearm, initially a .22 caliber revolver and later a .38 Special, to shoot her victims. The crimes occurred between December 1989 and November 1990.

Who Was Tyria Moore? Aileen Wuornos’s Girlfriend and Accomplice

Tyria Moore was Wuornos’s long-term partner and is described in some sources as a possible sexual partner and partner-in-crime. They met in South Daytona in 1986. The relationship is central to Wuornos’s biography because it appears in accounts of her personal life, her movements in Florida, and the investigation.

The Relationship

Wuornos and Moore lived together in motels and along Florida highways during the period of the murders. Moore was present during some of the crimes and spent proceeds from the killings. According to the material provided, Moore helped build the case against Wuornos, and Wuornos later absolved Moore of involvement.

Moore’s Role in the Investigation

Why Was Aileen Wuornos Executed? Trial and Death Penalty

Wuornos was arrested in 1991 after a multi-state investigation.

Trial and Defense Strategy

Wuornos’s defense initially argued that she acted in self-defense against men who had raped or attempted to rape her. She later abandoned that defense. Her sanity was questioned during the proceedings, but the courts found her competent to stand trial. Public accounts note that her mental state remained a point of contention throughout the legal process.

Certainty vs. Uncertainty: Key Debates in the Wuornos Case

Analysis and Context: Gender, Media, and the Death Penalty

Wuornos’s case sits at the intersection of several ongoing debates. Gender bias in serial killer profiling is a recurring theme: female serial killers are rare, and Wuornos was often portrayed as a “monster” while male counterparts receive more psychological study. The self-defense argument is rooted in her life as a sex worker and victim of sexual assault, a context that was hotly contested at trial.

Her case is cited in discussions about the death penalty for defendants with intellectual or mental disabilities. The legal legacy of her trial continues to be examined in law and psychology courses. Media coverage has evolved from tabloid sensationalism to more measured analysis, particularly with the release of the 2025 Netflix documentary highlighting systemic failures.

Comparisons are sometimes drawn with other female serial killers such as Karla Homolka and Myra Hindley, though the circumstances of their crimes differ significantly. Wuornos remains a singular figure in the true crime landscape because of the intersection of poverty, sex work, abuse, and capital punishment in her story.
