Deep in the Indian Himalayas, at over 16,000 feet above sea level, lies Roopkund — a small glacial lake with a gruesome secret. Every summer, when the ice melts, hundreds of human skeletons emerge from the water's edge. Discovered by a British forest ranger in 1942, the remains sparked decades of debate: Japanese soldiers? Victims of a medieval plague? A cursed royal pilgrimage? Then DNA analysis revealed something no one expected — some of the dead weren't even from the same continent, or the same century. In this episode of The Dark Folio, we wade into one of history's strangest cold cases.
