DENVER-- Authorities searching for a 10-year-old Colorado girl say they believe she was abducted by an unknown suspect, and they're confident her parents weren't involved.
Jessica Ridgeway was last seen Friday after leaving home to meet friends at a park so they could walk to school together in the Denver suburb of Westminster.
Westminster police spokesman Trevor Materasso said Wednesday investigators believe the girl was abducted.
Police say they are pursuing tips from Nevada, Texas, Maryland and Maine, where a possible sighting of Jessica was reported.
