A telephone call to police by a Swiss national may by the key to solving the mystery of the identity of a skeleton stumbled upon by two hikers in remote bushland south of Hobart last week.
The human bones were found away from marked tracks in the Huon Valley, 10 kilometres west of the popular Tahune Airwalk and police believe they belong to a 44-year-old Swiss tourist who's been missing for more than six years.
A backpack found near the remains contained a SD photo card and a photograph that was extracted from it was released to the media on Friday. Police say that prompted a call from a Swiss man who said he believed the remains are of his friend.
Food, clothing, Swiss Francs, Hong Kong dollars and receipts for exchange in Switzerland in December 2010 were also found in the backpack.
"He believes he is the man in the photo, and the missing man may be his friend. He said the photograph was taken on the coast of Oregon, USA in 2010, " police said in a statement on Sunday.
"He said his friend was a forty-four-year old Swiss man who had previously visited Tasmania and he was last seen by his family in December 2010 when he left Switzerland to go travelling."
Detective Acting-Sergeant Michael Manning said police are still working to identify the man and said it is important to provide "answers for the deceased's family and return the remains to them."
