Austin Sigg, 17, has been charged as an adult on 17 counts in the horrific murder of Jessica Ridgeway and a Ketner Lake Attack.

In charging documents, prosecutors said Sigg acted alone in kidnapping, robbing, and sexually assaulting Jessica. 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. There was also an additional attack on a runner who reported being grabbed from behind by Austin Sigg who placed a rag with a chemical smell over her mouth.

Sources have told ABC News that Austin Sigg confessed to the murder of Jessica Ridgeway to his mother. We do not know why at this time, but some believe that the wooden cross found at the crime scene provided the break in the case.  Perhaps that was the moment when Austin Sigg’s mother, a single mother, started questioning the boy.

Austin Sigg’s father has a long criminal record which inludes Bank Fraud and is being looked at as the investigation continues, although he has not been named as a suspect in connection with the murder of the little girl.  What is still missing is the crime scene, an obvious place where Jessica would have been dismembered. Would a 17-year-old young boy be able to do such a thing and cover his tracks alone?

Details of his past show that schoolmates admitted making fun of him in school for having a high pitched voice, he wore black, and often kept to himself. He didn’t graduate high school but received his GED which allowed him to attend Warren Tech, where he won second place in a Health Occupations Students of America competition in the category of crime-scene investigation.

Jessica’s heart broken Great Grandmother said at the court when asked about Austin Sigg, “Light him on fire, send him to hell in a blaze of Glory.”
