May 2008 – Inyo County sheriff’s investigators Wednesday ended their search for human remains at a remote Death Valley National Park ranch used in 1969 as a hide-out by Charles Manson and his followers.
“One bullet casing was found in the site,” Inyo County Sheriff’s Lt. Jim Jones said, “but forensic testing indicates that there were no human remains in or around that site.”
Excavation of a second potentially promising site yielded only remnants of ash and small animal bones. That spot was turned over to the National Park Service to be handled as an archaeological site.
