This is Part 1 of our our 3 Part in-depth series on The Somerton Man. Of the six questions — who, what, when, where, how and why — we only know three when it comes to the mystery of "The Somerton Man." What and where: a middle-aged man found dead on Somerton Beach, which borders the Adelaide, Australia, suburb of Glenelg. When: he was found by passersby at 6:30 a.m. on December 1, 1948. As for the remaining questions, authorities, academics, authors, Australians and curious citizens the world over have been seeking answers ever since.
