Chilling last words of serial killer before she was executed

***Warning: this article mentions sexual assault.***

Serial killer Aileen Wuornos issued a chilling final statement just moments before she was executed - vowing that she would ‘be back’.

Wuornos was working as a sex worker when she shot, killed and robbed seven of her clients between 1989 and 1990.

Wuornos was apprehended in January of 1991 and confessed to the killings, but claimed that she had acted in self-defence and that the men she had killed had all either raped her or attempted to rape her.

She went to trial the following year, where she was convicted - and given the death penalty for the murder of Richard Mallory.

Later the same year, she pleaded no contest to the murders of Charles Humphreys, Troy Eugene Burress and David Spears, and pleaded guilty to the murder of Charles Carskaddon and Walter Antonio.

In total, she was given six death sentences and ordered to live out the rest of her days at Florida Department of Corrections Broward Correctional Institution death row.

In the case of a seventh victim - 65-year-old Peter Siems - no charges were ever brought as his body was never found. However, Wuornos' palm print was found on the interior door handle of his car.

Following her incarceration, Wuornos took part in two Nick Broomfield documentaries; Aileen Wuornos: The Selling of a Serial Killer and Aileen: Life and Death of a Serial Killer, where she spoke about her crimes.

In 2001, Wuornos said it was a ‘waste’ to keep her alive and urged the state to execute her.

“There is no point in sparing me," she said in July 2001. "It's a waste of taxpayers' money."

She went on to say: "I killed those men, robbed them as cold as ice. And I'd do it again, too.

"There's no chance in keeping me alive or anything, because I'd kill again. I have hate crawling through my system."

And the following year, after more than a decade on death row, Wuornos got her wish and was put to death by lethal injection aged 46.

According to reports at the time, Wuornos ‘smiled at witnesses’ as she sat in the execution room.

When asked if she would like to make a final statement, Wuornos replied: "Yes, I would just like to say I'm sailing with the rock, and I'll be back, like Independence Day, with Jesus. June 6, like the movie. Big mother ship and all, I'll be back, I'll be back".
