Mind of a Monster season 1 revisits the Aileen Wuornos murders through letters, recordings, and case files. Episode 2 traces the killings, the evidence path that led to an arrest, and the claims Wuornos made about what happened on Florida highways in 1989 and 1990.
The episode titled Aileen Wuornos originally aired on January 1, 2020, and re-aired recently on October 12, 2025, on Investigation Discovery.

Case background and timeline
Wuornos was born in 1956 and was executed in Florida on October 9, 2002. She was convicted of six counts of first-degree murder and admitted involvement in a seventh case in which the body was never found.
CNN reported she was pronounced dead at 9:47 am after lethal injection, following more than a decade on death row. According to the Associated Press, the death sentences were imposed across several counties tied to separate victims.
Between late 1989 and 1990, seven men were shot with a .22-caliber handgun. Victims included Richard Mallory, David Spears, Charles Carskaddon, Peter Siems, Troy Burress, Charles ‘Dick’ Humphreys, and Walter Antonio.
ABC News described Wuornos as the first woman to fit the FBI’s serial killer profile, a point the episode notes while also presenting her repeated self-defense claims.
Investigation and arrest in Mind of a Monster season 1
The program lays out how vehicle and property trails became key. Peter Siems’s car was found crashed and abandoned on July 4, 1990, with witnesses describing two women walking away.
Pawn slips tied to items from victims, plus a thumbprint, linked to Wuornos’s known aliases. Orlando Sentinel coverage recounted those steps and the later fingerprint match.
Detectives then located Tyria Moore, Wuornos’s partner at the time. Under supervision, Moore made recorded calls in which she appealed for help clearing her name. Wuornos subsequently confessed to multiple killings while continuing to assert attacks by clients, as summarized in AP and Sentinel reporting.

On January 9, 1991, authorities arrested Wuornos at The Last Resort bar in Volusia County. The episode uses archival video and interviews to show the progression from the street to the interrogation room and then to formal charges.
Legal process and claims in Mind of a Monster season 1
The courtroom path starts with the Mallory case. Florida’s evidentiary rules allowed jurors to hear about other homicides to show a pattern. Wuornos testified to rape and violent assault, then later entered pleas in several cases.
According to the Orlando Sentinel, jurors recommended death, and the courts imposed six death sentences. Statements shifted over time. She initially framed every shooting as self-defense, then later wrote and said she acted out of rage and robbery in some incidents.
What the Mind of a Monster season 1 episode adds
Episode 2, Aileen Wuornos, centers on writings Wuornos reportedly prepared while on death row for a close friend. Those pages, read on screen, track with earlier interviews and offer her account of risk on the road, alleged assaults, and why she carried a gun.
The program also walks through scene details that investigators emphasized: abandoned vehicles, items pawned under aliases, and a single firearm type linked by ballistic characteristics. According to CNN, the execution marked the end of a case that combined confession tapes, property evidence, and witness sightings.
The Mind of a Monster season 1 episode keeps the focus on documents and on-camera records rather than dramatization. It sets claims beside the physical record and lets case chronology do most of the work.
Aileen Wuornos episode of Mind of a Monster season 1 can be streamed on HBO Max, YouTube TV, Philo, Investigation Discovery, and Discovery+. The episode can also be digitally purchased on Amazon Video, Fandango At Home and Apple TV.
