FBI helping hunt for American woman Aubrey Sacco missing in Nepal THE FBI says it's helping the US State Department in the investigation of a Colorado woman who disappeared while trekking alone in Nepal. Denver FBI spokesman Dave Joly said today the agency was also working with Nepalese authorities on the disappearance of 23-year-old Aubrey Sacco of Greeley. Ms Sacco has not been heard from since April 20, when she e-mailed her parents from Nepal. She planned to finish her trip around April 30. Her father, Paul Sacco, told the Greeley Tribune that FBI agents had made two or three visits to his home. Paul Sacco went to Nepal in May to look for his daughter. He said he recovered her laptop computer and journal from a hotel. Aubrey Sacco graduated from the University of Colorado last year.
