Williams Rule

The prosecution painted the picture of a cold-blooded killer who murdered her victims during robberies.

They were able to introduce evidence from her other crimes under Florida's Williams Rule, which allowed the prosecution to establish a pattern, and that crumbled her claim of self-defense.

For their part, Aileen's defense team argued that she suffered from borderline personality disorder and antisocial personality disorder, which impaired her judgment.

They claimed she killed Mallory in self-defense after he violently raped her.
