Next month marks 30 years since infamous serial killer Ted Bundy was executed.
On 24 January 1989, he was strapped into the electric chair and put to death for his crimes, but just hours before he gave his final interview and spoke to campaigner Dr James Dobson about his early life and what drove him to commit his atrocities.
In the chilling 45-minute interview Bundy talked about how his obsession with pornography drove him to become a sinister, calculating killer.
He said: "As a young boy - and I mean a boy of 12 or 13 certainly - I encountered outside the home softcore pornography. From time to time we'd come across pornographic books of a harder nature, more graphic you might say. And this also included such things as detective magazines.
"The most damaging kinds of pornography are those that involve sexual violence, because the wedding of those two forces, as I know only too well, brings about behaviour that is just too terrible to describe."
But as his obsession grew, he explained to Dr Dobson, the kind of porn he was looking at became more aggressive and explicit.
He said: "My experience with pornography that deals on a violent level with sexuality is that once you become addicted to it - and I look at this as a kind of addiction - like other kinds of addiction...I would keep looking for more potent, more explicit, more graphic kinds of materials.
"Like an addiction, you keep craving something which is harder, harder. Something which gives you a greater sense of excitement. Until you reach the point where the pornography only goes so far."
The murderer went on to say that eventually images and film weren't enough - he had to try things for himself.
"You reach that jumping-off point where you begin to wonder if maybe actually doing it will give you that which is beyond just reading about it or looking at it," Bundy added.
He claimed he was stuck at this 'jumping off point' for about two years before he began assaulting and murdering young women and girls.
One of the eeriest parts of the interview however, sees Bundy describing how he appeared from the outside to be just a 'normal' person, who no one would suspect of harbouring such dark secrets.
He said: "I was essentially a normal person. I had good friends. I lived a normal life, except for this one small, but very potent, very destructive segment of it that I kept very secret, very close to myself, and didn't let anybody know about.
"And part of the shock and horror for my dear friends and family, years ago when I was first arrested, was that there was no clue. They looked at me, and they looked at the all-American boy.
"I think people need to recognise that those of us who have been so much influenced by violence in the media - in particular pornographic violence - are not some kinds of inherent monsters.
"We are your sons, and we are your husbands. And we grew up in regular families. And pornography can reach out and snatch a kid out of any house today."
The 42-year-old, born Theodore Robert Bundy, was convicted of murdering 30 women, including 12-year-old Kimberly Leach.
However, some believe the actual total could be much higher, accounting for the murder and sexual assault of many young women throughout the 1970s.
Netflix has announced it is releasing a four-part docuseries about the deranged killer, titled Conversations with a Killer: The Ted Bundy Tapes, which will feature never-heard-before audio interviews from when Bundy was on death row.
