His body lay in the Goldfields bush for almost a decade until a gold prospector's chance find raised more questions than answers.
It was as if the man fell asleep and never woke. His intact skeleton lay on the remains of a sleeping bag and mat under a shady tree in scrub about 30km east of Kalgoorlie.

The only clues about him were a few scattered possessions battered by years of exposure.
Under his head in a small blue bag was a wallet with no identification, just $10 and a few coins.
An international search was sparked after the find but almost six months later, the man's identity remains a mystery.
His death is not believed to be suspicious but Kalgoorlie Det-Sgt Chris Page and missing persons unit Const. Chelsea Magowan said they liked to think a family was missing him.
"We also want to find out for him, so he can be returned to his loved ones and given a proper burial," Const. Magowan said.
Forensic analysis show he was predominantly Caucasian, aged 30 to 50, between 172.5cm to 178.5cm tall and probably died between 2001 and 2003.
X-rays of extensive Western dental work are being compared with missing persons' reports but inquiries in Australia and overseas have turned up nothing.
Experts are trying to get a DNA sample from the man's bones to check against database profiles.
A 10Â¢ coin in his wallet was minted in 2001 and a pack of cigarettes had the slogan When Only the Best Will Do, used only until 2003.
Police suspect he was Dutch or German because of words on clothing tag remnants and on a lighter from Dutch oil company Total.
The man had no prospecting or cooking gear, little clothing and was not near any camp spots.
Det-Sgt Page said the man had a compass. "The way he is equipped, I suspect he was doing a short overnight hiking trip," he said.
Most of his clothing was lost to the weather with just scraps - including a label for an XXL shirt and three Stax jeans buttons - intact.
No passport or spare clothes were found and one theory is he left those at a base, in a car or at a hostel but there is no record of them.
