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, as well as in a May attack on a runner, authorities said Wednesday.
Police in the Denver suburb of Westminster said they took 17-year-old Austin Reed Sigg into custody Tuesday night after receiving a phone call, apparently from his mother, that led them to Sigg. He was officially arrested Wednesday.
Reached by phone Wednesday, Sigg’s mother said he turned himself in.
Police 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.
