LAWRENCE, Kan. (AP) _ A registered sex offender has a March 17 trial date in Douglas County on charges that he tried to enlist a woman and her teenage daughter to become his sex slaves.

Police say Derek Marsocci of Centerview, Missouri, on Dec. 13 arrived at a shopping mall parking lot in Olathe, Kansas, to meet a 13-year-old girl and her mother. But instead he was greeted by Baldwin City police who conducted an undercover sex sting on the Internet.

Investigators say the long-haul trucker was carrying engraved dog tags for his two new sex slaves in the cab of his truck when he was arrested.

The Missouri Sex Offender Registry says Marsocci has a 2002 conviction for fourth-degree sexual assault in Fort Smith, Arkansas.

He was bound over for trial in a preliminary hearing Wednesday.
