Taman Shud: The world's most mysterious cold case?

Nice write-up at the Smithsonian's site on a real puzzler.

The Body on Somerton Beach


And the only thing that seems to have changed since then is that a story that began simply—with the discovery of a body on the beach on the first day of that southern summer—has become ever more mysterious. In fact, this case (which remains, theoretically at least, an active investigation) is so opaque that we still do not know the victim’s identity, have no real idea what killed him and cannot even be certain whether his death was murder or suicide.


What we can say is that the clues in the Somerton Beach mystery (or the enigma of the “Unknown Man,” as it is known Down Under) add up to one of the world’s most perplexing cold cases. It may be the most mysterious of them all.
