In the late 1980s, Germany's Federal Criminal Police Office confirmed that "Tatunca Nara" was born as Günther Hauck in Coburg, Bavaria, and disappeared in the early 1960s due to financial difficulties.
[1] In the 1970s, German foreign correspondent Karl Brugger met "Tatunca Nara", who told him of the history of Akakor, an underground city below the rain forest.
Still working as a jungle guide, Tatunca Nara led tourists and adventurers looking for pyramids and the underground city, but questions were raised after several of his clients went missing: American John Reed in 1980, Herbert Wanner of Switzerland in 1983, and Swede Christine Heuser in 1987.
In the same year, Brugger was shot and killed by an unknown assailant in the streets of Rio de Janeiro.
[citation needed] In 1990, German adventurer Rüdiger Nehberg and film producer Wolfgang Brög tricked Tatunca into taking them on an expedition, during which his story began to unravel.
