WESTMINSTER, Colo. - A teenager who lived just a mile from a 10-year-old Colorado girl who was abducted and killed earlier this month has been arrested in her death, along with a May attack on a runner, authorities said Wednesday.
Police in the Denver suburb of Westminster said they arrested 17-year-old Austin Reed Sigg on Tuesday night after receiving a phone call, apparently from his mother, that led them to Sigg.
Reached by phone Wednesday, Sigg's mother told The Associated Press he turned himself in.
"I made the phone call, and he turned himself in. That's all I have to say," said Mindy Sigg, before she broke down in tears and hung up.
Police announced the arrest as agents searched Sigg's home, but they have released few details about the investigation. Court documents have been sealed, but a police custody report said Sigg was cooperative when he was arrested and waived his rights.
Jessica Ridgeway disappeared Oct. 5 while walking to school. Her body was found five days later in a field at a park.
The break in the case came a day after police said Jessica's abduction was linked to the May 28 attempted kidnapping of a 22-year-old runner at another park, the Ketner Lake Open Space.
In that case, a woman fought off a stranger who grabbed her from behind and put a rag that smelled of chemicals over her mouth, authorities said. Westminster investigator Trevor Materasso said Tuesday police haven't been able to determine if the substance on the rag was meant to subdue the woman.
