A 25-year-old St. Paul man pleaded guilty in U.S. District Court in Minneapolis on Friday to recruiting and trafficking teenage girls for prostitution throughout Minnesota.

Dontre D'Sean McHenry recruited at least three girls under the age of 18 and prostituted them for his own financial benefit, according to a news release from U.S. Attorney Andy Luger.

McHenry advertised girls on backpage.com and in chat rooms, and made a sexually explicit video of a 15-year-old victim that was sent out to prospective "johns," the U.S. attorney's office said.

During a search warrant, authorities found a book entitled "Pimpology: 48 Laws of the Game" with handwritten notes in the book about the recruiting and coercing of minors.
