Paul David Ensign, 60, is being held in the Benton County Jail on charges out of Louisiana for sexual solicitation of a child and trafficking children for sexual purposes.
He'll be facing additional charges of indecent behavior with a minor and prostitution.
Lousiana State Police say Ensign arranged through Craigslist to pay for a 13-year-old girl to live with him for a sexual relationship.
Police say he also sent the girl text messages with sexually explicit pictures.
He'll eventually be sent to Lousiana to face charges.
