Police say they are draining a pond in a park north of San Diego in their efforts to find a girl who vanished about a year ago in the same region where 17-year-old Chelsea King disappeared last week.

Escondido police Lt. Craig Carter says investigators on Friday located a bag near the pond that three children reported finding in May — three months after 14-year-old Amber Dubois vanished while walking to school. The children told their parents the bag contained what looked like human hair, but the parents didn't think that was significant at the time.

Carter says the bag doesn't appear to be connected to the Dubois case, but an FBI evidence response team will analyze the contents.
