Who is John Tanner? All about the key figure associated with the Aileen Wuornos case

Aileen Wuornos anchors the Netflix feature Aileen: Queen of the Serial Killers, and one name that stands out in the record is John Tanner. He served as state attorney in Florida during the period when investigators brought the case to court, and he led the prosecution that secured the first conviction.

The film revisits the crimes, the arrest, and the courtroom tapes. Through that lens, John Tanner appears again and again as the public face of the state’s case. His courtroom statements, media comments, and charging decisions shaped how the story reached the jury and the wider audience.

Case overview of Aileen Wuornos

Between late 1989 and late 1990, seven men were found shot and left on Florida roadways. Evidence included pawn slips tied to the victim's property, fingerprints from a crashed vehicle, and taped calls set up with Tyria Moore that led to a confession.

Wuornos was arrested in January 1991 and later received multiple death sentences. The documentary’s archival record shows routine police work knitting the cases together, then moving into trial.

Who is John Tanner in the Aileen Wuornos case

John Tanner was the elected state attorney whose office tried the first case, the killing of Richard Mallory. A born-again Christian by public description and reportedly an anti-pornography crusader at the time, Tanner framed the murders as calculated crimes.

He pushed a narrow theory of motive, emphasized robbery, and opposed defense claims of self-defense. His presence at the podium, flanked by local press interest, made him a central figure for viewers of the trial footage and for the jurors who heard it live.

Tanner’s role also extended to decisions about what jurors could hear. Under Florida’s Williams Rule, the state introduced evidence from other shootings to show a pattern. That approach, common in Florida practice, increased the weight of the state’s narrative and reduced the case’s dependence on a single incident.

Aileen Wuornos' trial strategy and John Tanner’s stance

At trial, the defense focused on sexual violence claims and on Mallory’s past. The state, led by Tanner, insisted the shootings fit a robbery pattern. His words from the era still circulate in coverage of the film:

“This was not so much a crime of passion as it was a crime of absolute control and domination over the victim.” -John Tanner said of Richard Mallory's murder in archival footage

That line comes from archival footage used in the documentary and captures how the prosecution framed intent.

The resulting split has long been discussed. Defense accounts stressed a life history of abuse and alleged assaults during encounters. Prosecutors stressed route, method, gun, property, and repeated elements. The jury convicted on the Mallory count; Wuornos then entered no-contest pleas in other cases. The sentence phase produced death, later carried out in 2002.
