The identity of a man discovered dead in Sydney, Australia, nine months ago has stumped authorities. Was he living in the country in secret?

Axar.az reports citing BBC.

His body was found just as the sun was rising over Beamish Street in Campsie, a mostly working-class suburb.

The man, aged over 50 and "of Asian appearance", had died of an apparent suicide outside a unit block, authorities said. He had no wallet, phone or documents of any kind.

The only clue to his life was an electronic transport card found in his pocket.

The Sydney-wide Opal card is sometimes used by police to help identify deceased people. Opal cards are normally registered to a home or email address, and linked to a bank account.

This one, however, was unregistered. Adding to the puzzle, the card had been topped up with cash in a location that did not have security cameras.

What is known is that the man's trips always began or ended at a bus stop known as "Dan's Corner", not far from where his body was later found.

His final bus journey, on 10 April, took him only about 250m (800 feet). It ended at a stop outside an Asian grocery store.
