California ? Searchers have found what appear to be two large human bones near the crash site of Steve Fossett’s plane in California’s Sierra Nevada, along with the adventurer’s tennis shoes and driver’s license, authorities said Thursday.

Madera County Sheriff John Anderson said at a news conference that the bones were found Wednesday about a half-mile east of the crash site. Investigators have sent them to a Department of Justice testing lab and should know in about a week whether they are Fossett’s.

Anderson said searchers also found Fossett’s tennis shoes, his Illinois driver’s license and credit cards.
