Prosecutors said in court filings that 34-year-old Taquarius Ford found a "memoir" titled "Denial of a Pimp" on his computer.
It outlined how he went about pimping out women, and why he targeted smaller areas.
Prosecutors say he found an 18-year-old woman at a Boise area mall. He claimed to be a modeling executive and thought she had an opportunity to make it.
Ford even had several pictures of himself with celebrities.
Groups like The Ivy Movement, who are trying to stop sex trafficking in the Treasure Valley, said the modeling promise is an old trick used by pimps.
"Every girl wants to hear that she looks like a model every girl wants an all expense paid trip to SoCal," said Ivy Movement co-founder Stacey King. "But the reason they target smaller towns is because it's so safe to traffic women here and not get caught."
Prosecutors said Ford took the Idaho woman to California, and even went to a party at the Playboy Mansion. King said this is what pimps do to groom their victims.
Eventually authorities said Ford tried to get the victim to become an escort, and when she protested he raped her and beat her.
She was eventually rescued by an alert hotel clerk in Portland in 2012. Ford was indicted by a federal grand jury, and is behind bars while he awaits his trial scheduled for June.
Meanwhile, King and others are trying to bring the issue of sex trafficking to the forefront of people in Idaho. She said until more people start taking the issue seriously then pimps will continue to target the Treasure Valley.
"A pimp has said 'I came through here once I did so well that I came through here again,'" said King. "'We know we won't get caught here and we make so much money here.' So men here are buying, and children here are being trafficked."
