WESTMINSTER, CO - ABC News is reporting that the 17-year-old arrested for the murder of Jessica Ridgeway confessed to his mother, who then called police in Colorado so her son could turn himself in, sources say.
Austin Reed Sigg was arrested Tuesday on suspicion of two counts of first-degree murder, one count of second-degree kidnapping and two counts of criminal attempts.
The charges stem from Jessica's death and the alleged May 2012 attempted abduction of a jogger.
Sigg will appear in court Thursday and the district attorney says he plans to charge the teen as an adult.
Investigators worked through the Westminster, Colorado home where Sigg lives with his mother. The FBI is assisting in the investigation.
Jessica disappeared October 5 when she left for school. Her body was found five days later.
Sigg also lives near a reservoir where he allegedly tried to abduct a 22-year-old female jogger on May 28.
Authorities said there is a definite link between Jessica's case and the abduction attempt, according to ABC News.
