Authorities have filed federal charges against a man and woman from Tennessee accused of driving a 15-year-old girl they met through Facebook to Illinois to engage in prostitution.

The U.S. Department of Justice said Wednesday that 22-year-old Jessica Lidy and 30-year-old Jarrod Sanford of Friendship, Tenn., have been charged with transportation of a minor to engage in prostitution. They have not entered pleas.

Lidy and Sanford were arrested Oct. 7 in Lincoln after the girl told gas station employees she was being held against her will in Sanford's truck.

Sworn statements by an FBI agent indicate Lidy and Sanford said they would take the girl on a trip and Lidy would work as a prostitute and share money with her.

Charges initially filed in Logan County have been dropped.
