This was based on a true story

Nobody may care but I just watched a movie entitled Smooth Talk and I did some research and found that it was based on a short story by Joyce Carol Oates. So I was reading about her story and how it was based on a true story about this guy who they called the pied piper of Tucson. Then I did some more research and found the entire true story on Courtv's wedsite http://www.crimelibrary.com/serial_killers/predators/schmid/sand_1.html
