A few weeks ago I read a Cracked article on real-life horror movie plots, and they mentioned David Parker Ray.
The story if his crimes wasn’t what got to me.
He made a tape recording that he left in a cassette player for his female victims to listen to upon capture.
They provided a link to a site with the transcript of one of those tapes. I read about half way through before I realized I was consuming prime nightmare material. I would be happy if I never remembered the content of that transcript again. Don’t google it.
