(CNN) -- Jessica Ridgeway's suspected killer is a 17-year-old neighbor who authorities plan to try as an adult, officials in Colorado said Wednesday.
Formal charges against Austin Reed Sigg, a high school student who lived about one mile from the 10-year-old and her family, likely will be filed Monday, Jefferson County District Attorney Pam Russell said.
As a general policy, CNN does not show the booking photo or name suspects who are juveniles, but in this case, police had mentioned Sigg's name and released his photograph in hopes the public could provide information related to the case.
Sigg will face murder and kidnapping charges in death of Ridgeway, who was found a few days after she disappeared on her way to school on October 5. Her body -- which was "not intact," according to police -- was found at a park in Arvada, a Denver suburb just five miles from the family's home in Westminster. Read More
