The suspect arrested in the abduction and slaying of 10-year-old Jessica Ridgeway appeared in Jefferson County Court on Thursday morning for an advisement hearing.
Austin Reed Sigg, 17, a student at Arapahoe Community College in Littleton, likely will be tried as an adult, District Attorney Scott Storey said. Storey said, however, that the death penalty could not be applied in the case since Sigg is not yet 18.
Sigg, of Westminster, was denied bond and will remain at the Mount View Youth Services Center in Lakewood. District Court Judge Gail Ann Meinster presided.
Meinster read the arrest affidavit, which has been sealed from the public, and said the issues warranted that Sigg be held in dentention for the time being.
Sigg's next court appearance is scheduled for Oct. 30, at which time he will be advised of the charges against him.
Westminster police announced Wednesday morning that Sigg was arrested late Tuesday after a tip led police to a home near Ketner Lake Open Space in Westminster.
Sigg is also a suspect in the attempted abduction of a woman who was jogging at Ketner Lake on May 28. Authorities said earlier this week the attempted abduction was likely connected to Jessica's kidnapping and murder.
Sigg reportedly will be charged with two counts of first-degree murder and with second-degree kidnapping.
According to police, Sigg is a student Arapahoe Community College.
Jessica vanished Oct. 5 after she left her Westminster home to walk to school. Her body was found 11 miles away in Arvada open space on Oct. 9.
