Officials end search at Fossett's crash site

Mammoth Lakes, California: Investigators finished up Friday at the scene of Steve Fossett's plane crash in the wilderness of the Sierra Nevada mountains just as dark clouds rolled in and winds picked up ahead of a storm that threatened to bury any remaining evidence under 0.61 metres of snow.

They discovered three more bone fragments Friday, said a spokesperson for Madera county sheriff's department. Like a piece found the day before, they will be sent to a lab to determine whether they are human and a match for Fossett, the famous adventurer.

Teams of volunteers - as well as local and federal search crews - had been furiously combing the site for any evidence that could help piece together the mystery surrounding Fossett's plane crash more than a year ago.
