Retired FBI agent and criminal profiler Candice DeLong says executed murderer Karla Faye Tucker's disturbing confession about experiencing sexual arousal during her crimes has continued to haunt her years later. DeLong, who hosts the true crime podcast 'Killer Psyche,' believes Tucker's troubled upbringing and early drug use contributed to her violent streak, making her 'doomed' from the start.

Why it matters

Tucker's case remains central to debates over capital punishment and rehabilitation, with some arguing her religious conversion in prison was genuine while others believe she was 'everybody's worst nightmare' - a violent offender who took pleasure in her crimes.

The details

Tucker and her then-boyfriend Daniel Ryan Garrett broke into the apartment of Jerry Lynn Dean in 1983, intending to steal motorcycle parts. During the burglary, both Dean and Deborah Thornton, who had met Dean that evening, were killed. Tucker later admitted to participating in both killings and told police she experienced sexual arousal during the attack, though she later appeared to distance herself from those statements. DeLong attributes Tucker's violent behavior to her 'sad and horrible childhood' filled with drug use, neglect, and a lack of a stable upbringing.

  • In 1983, Tucker and Garrett committed the murders of Jerry Lynn Dean and Deborah Thornton.
  • Tucker was convicted and arrived at the Texas State Penitentiary in 1984.
  • Tucker was executed in 1998 at the age of 38, becoming the first woman executed in Texas since the Civil War.

“Karla was doomed from the beginning, once people found out what she did. And the worst thing she did, and she did not help herself by telling people this, that she had an orgasm when she was killing, while she was stabbing someone.”

— Candice DeLong, Retired FBI Agent

“Karla never stood a chance, a chance of having a normal life, in my opinion. She didn't get what she needed, and she got a lot of bad stuff from someone who was supposed to take care of her.”
