Netflix’s gripping documentary Aileen: Queen of the Serial Killers has reignited interest in one of America’s most notorious criminal cases, spotlighting key figures who shaped the prosecution. Among them, John Tanner emerges as a central character whose courtroom strategy and public statements fundamentally influenced how the case unfolded and how the story reached both the jury and the wider public.
As Florida’s state attorney during the early 1990s, Tanner led the prosecution that secured Aileen Wuornos’ first conviction in the murder of Richard Mallory. His approach to the case—emphasizing robbery over self-defense claims—became the blueprint for understanding one of history’s most controversial serial killer cases.

Understanding the Aileen Wuornos Case
Between late 1989 and late 1990, seven men were discovered shot and abandoned along Florida roadways. The investigation connected the murders through evidence including pawn slips tied to victims’ property, fingerprints from a crashed vehicle, and recorded phone conversations with Tyria Moore that ultimately led to Wuornos’ confession and arrest in January 1991.

Who is John Tanner?
John Tanner served as the elected state attorney whose office prosecuted the first and most publicized case against Wuornos. Described as a born-again Christian and anti-pornography crusader, Tanner framed the murders as calculated, premeditated crimes driven by robbery rather than self-defense.
His prosecutorial theory rejected defense claims that Wuornos acted in response to sexual assault, instead emphasizing patterns of robbery, method, and intent. His courtroom presence and media statements made him the public face of the state’s case, shaping how both jurors and the general public perceived the crimes.

Tanner’s Prosecution Strategy
The state attorney’s approach centered on establishing a clear pattern of criminal behavior. Under Florida’s Williams Rule, Tanner introduced evidence from other shootings to demonstrate consistency in method and motive. This legal strategy, common in Florida practice, significantly strengthened the prosecution’s narrative beyond relying on a single incident.
In archival footage featured in the Netflix documentary, Tanner’s words reveal his interpretation of the crimes: “This was not so much a crime of passion as it was a crime of absolute control and domination over the victim.” This statement encapsulates how the prosecution framed Wuornos’ intent, contrasting sharply with defense arguments centered on a history of abuse and alleged assaults.
The defense emphasized sexual violence claims and Richard Mallory’s troubling past, while Tanner’s team focused on route, method, weapon evidence, stolen property, and repeated behavioral elements. The jury ultimately convicted Wuornos on the Mallory count, after which she entered no-contest pleas in the remaining cases, resulting in death sentences later carried out in 2002.

Tanner’s Career After the Trial
Following the high-profile Wuornos prosecution, John Tanner returned to private practice before later serving again as state attorney. He has maintained a relatively low public profile in recent years, though he remains permanently linked to the case through documentaries like Netflix’s latest feature and news coverage that continues to replay his trial statements and prosecutorial decisions.
His role in the case continues to generate discussion among legal analysts, true crime enthusiasts, and those examining the intersection of justice, gender, and criminal defense strategies. The documentary revisits his courtroom tactics and public statements, asking viewers to reassess the evidence alongside police tapes, archived newscasts, and prison interviews.
