Austin Sigg, 17, who is accused of killing 10-year-old Jessica Ridgeway, will be tried as an adult. A Jefferson County judge also ordered Sigg to be transferred from the Mount View Youth Services Center to a special housing unit in the Jeffco jail.

A preliminary hearing in the case has been scheduled for Feb. 22, 2013. There will be another hearing on Dec. 12 to finalize the case’s transfer from the juvenile court system.
Sigg, a student at Arapahoe Community College, is being held without bail. He faces 17 counts, including 11 related to the abduction and killing of Jessica, including first-degree murder after deliberation, three counts of felony murder, second-degree kidnapping and robbery.
