(Newser) – Prosecutors say a teenager who allegedly confessed to killing a 10-year-old Colorado girl and attacking a runner also sexually assaulted the girl. Seventeen-year-old Austin Sigg was charged as an adult with 17 counts in both cases today, including four murder charges. If convicted as an adult, Sigg faces up to life in prison with the possibility of parole after 40 years. Defense attorneys anticipate asking the judge to send the case to juvenile court.

In charging documents, prosecutors said Sigg acted alone in kidnapping, robbing, and sexually assaulting Jessica Ridgeway. The robbery charge involved Jessica's backpack and water bottle, which were found in another suburb three days after she disappeared while walking to school Oct. 5. Jessica lived on a quiet street about a mile from where Sigg lived with his mother.
