O'Connor said the man had a unusual condition in which his kidneys were attached to each other. The condition would not have been obvious, but someone who knew the man well may have known that and could use the information in identifying the man, O'Connor said. The autopsy did not indicate the man was beaten, stabbed or shot, said Detective Sgt. Michael G. O'Connor, head of the sheriff's homicide detail. But, he said, decomposition hindered pathologists in determining whether there was soft-tissue damage, and foul play has not been ruled out.
Investigators estimate the body was in the desert one or two weeks before it was found.
