1948

On April 1, 2006, 27-year-old Brian Shaffer, an Ohio State University medical student, walked into the Ugly Tuna Saloona bar in Columbus for a night out with friends. Hours later, he vanished—never to be seen or heard from again, despite extensive surveillance footage and a thorough police investigation.

After seven decades, DNA analysis has reportedly identified the Somerton Man found dead on an Adelaide beach in 1948 as Carl 'Charles' Webb, though South Australia Police await official confirmation of one of the world's most baffling unsolved cases.
