A massive search is on in Colorado for a 10-year-old girl who went missing on her way to school on Friday.
Police say Jessica Ridgeway's backpack was found about six miles away from where she was last seen.
Police have been following many leads and have made their way to Missouri where the girls' great grandmother lives.
Volunteers searched all weekend looking through any open spaces for clues into her disappearance.
Police say they don't believe she was taken by a relative or someone else she may know.
