JACKSONVILLE, Fla. -

A 23-year-old Jacksonville man pleaded guilty Friday to child sex trafficking.

Clive Nelson faces up to life in federal prison. A sentencing date has not yet been set.

According to the plea agreement, Nelson enticed and recruited a 15-year-old girl to engage in commercial sex acts for him. Nelson advised the child that she could earn up to $600 per day working for him if she would permit him to advertise her on the Internet.

Nelson then took photos of the child wearing lingerie and posing provocatively. He used the photos to compile advertisements for sex with the child on various Internet advertising sites.

Nelson also rented local hotel rooms in Jacksonville and transported the child to these hotels. She engaged in commercial sex acts at the hotels with customers who responded to the ads and were willing to pay money to have sex with the child.

When potential customers arrived to have sex with the child, Nelson would engage in surveillance from the hotel parking lot to ensure that the offenders were not the police. Once the offender and the child completed the commercial sex act, Nelson would collect the money from the child.

Nelson prostituted the child in this fashion from Nov. 29 through Dec. 15, when police officers from a specialized patrol unit of the Jacksonville Sheriff's Office located Nelson and the child in a hotel parking lot.
