WESTMINSTER, COLO. (AP) -- Authorities in Colorado are searching for a 10-year-old girl who has been missing since she left for school Friday.
Some law enforcement agents with dogs were searching Jessica Ridgeway's suburban Denver neighborhood on Monday while about 100 others were searching an area near where a backpack believed to be hers was found.
She was last seen walking to a park where she meets classmates before school in Westminster. The backpack was found on a street in a residential neighborhood about 6 miles north. Police won't talk about the contents.
Authorities have received over 300 tips from the public. They've also stationed police officers at schools in the area, though there is no indication other children are in danger.
Over 800 volunteers searched for the girl Saturday.
