Florida cops have found a 170-page manual which explains step by step how to molest children.
Investigators have stated that they still want to know where it came from.
"I've never seen anything like it. It was pretty amazing when I first saw it just because how detailed it was," ABC News quoted Orange County Sheriff's Office Det. Philip Graves as saying.
The manual, which was apparently written by someone who calls himself "the mule," is a how-to of child molestation, even explaining where and how to find potential victims, the station reported.
"I was more amazed that someone would be as bold as to create an actual 170-page document that would detail how to do it," he said.
Among the many disturbing topics covered in the book is how to convince a victimized child not to tell his or her parents.
"We personally haven't worked a case on it, but it has been located within our region," said Graves.
Graves said that it is not a crime in Orange County to send the manual by e-mail or to possess it, but local and federal investigators are trying to track down where the manual initially came from.
