A 26-year-old registered sex offender is charged with a sexual assault at a Valleyfair dormitory earlier this month.

Austin Jones is accused of raping a Valleyfair worker in the early morning hours of August 7th outside the SCALE Regional Public Safety Training Facility near Jordan–roughly 13 miles southwest of the popular amusement park.

The facility–which is operated by Scott County–serves as a dorm for some Valleyfair employees.

Officials say DNA tests on a belt found around the victim’s neck matched Jones’ DNA.

At the time of his arrest, Jones was serving probation for a previous rape conviction involving a 14-year-old girl. Jones is currently being held in the Scott County Jail.
