"I've never seen anything like it. It was pretty amazing when I first saw it just because how detailed it was," said Detective Philip Graves with the Orange County Sheriff's Office (full interview) .
Deputies with the sheriff's sexual offender surveillance squad have been aware of the manual for the past six months. The sheriff's office received it through an email listserve.
"We personally haven't worked a case on it, but it has been located within our region," Graves said.
Graves told WFTV that sending the manual by email or possessing it is not a crime in Orange County. However, federal investigators are trying to track down where the manual initially came from.
"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.
The author uses an alias in the manual. He calls himself "the mule." Deputies believe whoever is responsible may have committed crimes against children.
