The Fawcett expedition was not expected back until 1927, but when its members failed to reappear the rumours started. Perhaps the colonel had lost his mind or his memory and lived out his life as the chief of a tribe of cannibals, or held captive against his wishes by Indians.
In 1931 a Swiss traveller called Stephan Rattin travelled into Mato Grosso north-north-west of Cuyaba, along the Rio Arinos, where he claimed to have met an elderly white man with a long beard, being held captive by Indians. He said the man revealed himself as Colonel Fawcett and showed him a signet ring, which he asked him to describe upon his return to São Paulo. Although doubted by many, Nina Fawcett said she recognsed the description of her husband's ring, stirring up enough interest for a second expedition to be mounted.
1947 a New Zealand schoolteacher by the name of Hugh McCarthy quit
his job and went in search of Fawcett s lost city of gold using carrier pigeons giving
news of his progress. The last related not only details of his imminent death but also
made reference to an earlier communication giving the exact location of the city: the
pigeon carrying that particular letter never arrived, and McCarthy himself was never seen again.
The author Harold T. Wilkins, reports in his book Secret Cities of Old South America (1950), how an anonymous informant had told him that a German anthropologist by the name of Ehrmann had seen Colonel Fawcett s shrunken head in a village in the Upper Xingú in 1932. Apparently the colonel had died defending his son Jack, who had broken some sort of tribal taboo.
In April 1933, a theodolite compass belonging to Fawcett was found near the camp of the Bacaari Indians in the Mato Grosso. The excellent condition of the compass led Fawcett's wife Nina to believe he was still alive. In a letter to Wilkins dated February 1940, she wrote: "that is reason to believe that Colonel Fawcett was still alive and working with his surveying instruments -- in the Mato Grosso jungle -- as recently as April 1933. My husband was then alive and working, and probably had a certain amount of freedom, though under constant surveillance of the Indian tribe which, I believe, captured them about 1926 or 1927, and with those people they were obliged to remain." Nina Fawcett claimed that she received telepathic messages from her husband as late as 1934.
Clarvoyants and spirtlists have claimed they have either been spritually contacted by Fawcett or have knowlage of his wherabouts or his fate, but as expected, none have been proved correct.
Geraldine Cummins, an Irish medium and psychic, stated in her book The Fate of Colonel Fawcett: A Narrative of His Last Expedition that she used her special powers to solve the mystery. She reported in 1936 that she was receiving mental messages from Fawcett and that he had found relics of Atlantis in the jungle but was ill and semiconscious. After four such messages communications ceased and then in 1948 another messgae was recieved in which Fawcett reported his own death.
Brian Fawcett says he had heard various tales with details concerning his father's disappearance. An Austrian by the name of Richter "claimed that my father was prisoner of a tribe in the Chaco, and had sired twenty daughters and eight sons, the eldest of which always carried a golden spear." There was also a Brazilian with a German name "writing weird and wonderful articles in a popular weekly, claiming that my father and brother were 'advanced souls' who were worshipped as gods by the Indians, and who were actually alive in a subterranean city called Matatu-Araracauga, in the Roncador section of Mato Grosso. There were several of these underground cities in Brazil, where dwelt the great spiritual avatars who ruled the world's events, and from these secret places issued flying saucers to make global reconnaissance flights."
