Austin Reed Sigg, who was arrested this week for the kidnapping and murder of 10-year old Jessica Ridgeway, reportedly confessed to the heinous crime, prosecutors said today.
During a court hearing this morning, authorities said Sigg - a student at Arapahoe Community College - admitted to taking Ridgeway's life and also to attacking a jogger in the area.
They also told a judge that "overwhelming" DNA evidence exists that links Sigg to the crime.
Sigg, 17, will be formally charged on October 30 and is being held on suspicion of first-degree murder, felony murder and kidnapping in relation to Ridgeway, who vanished on October 5 and whose body was discovered on October 18.
Police in the Denver suburb of Westminster said they took Sigg into custody on Tuesday night after receiving a call from his mother.
Mindy Sigg, meanwhile, told The Associated Press that her son turned himself in.
"I made the phone call, and he turned himself in. That's all I have to say," said Mindy.
