received the actual remaining skeletal bones of Fawcett and had them analysed scientifically. The analysis allegedly confirmed the bones were Fawcett's, but his son Brian Fawcett (1906–1984) refused to accept this. Villas-Bôas claimed that Brian was too interested in making money from books about his father's disappearance. Later scientific analysis confirmed that the bones were not Fawcett's. As of 1965, the bones reportedly rested in a box in the flat of one of the Villas-Bôas brothers in São Paulo. In 1998, English explorer Benedict Allen went to talk to the Kalapalo Indians, said by Villas-Bôas to have confessed to having killed the three Fawcett expedition members. An elder of the Kalapalo, Vajuvi, claimed during a filmed BBC interview with Allen that the bones found by Villas-Bôas 45 years before were not really Fawcett's. Vajuvi also denied that his tribe had any part in the Fawcetts' disappearance. No conclusive evidence supports the latter statement. Villas-Bôas story Danish explorer Arne Falk-Rønne journeyed to the Mato Grosso during the 1960s. In a 1991 book, he wrote that he learned of Fawcett's fate from Orlando Villas-Bôas, who had heard it from one of Fawcett's murderers. Allegedly, Fawcett and his companions had a mishap on the river and lost most of the gifts they'd brought along for the Indian tribes. Continuing without gifts was a serious breach of protocol; since the expedition members were all more or less seriously ill at the time, the Kalapalo tribe they encountered decided to kill them. The bodies of Jack Fawcett and Raleigh Rimell were thrown into the river; Colonel Fawcett, considered an old man and therefore distinguished, received a proper burial. Falk-Rønne visited the Kalapalo tribe and reported that one of the tribesmen confirmed Villas-Bôas's story about how and why Fawcett had been killed. Fawcett's signet ring In 1979, Fawcett's signet ring was found in a pawnshop. A new theory is that Fawcett and his companions were killed by bandits and the bodies were disposed of in a river while their belongings were despoiled. Russian documentary In 2003, a Russian documentary film, The Curse of the Incas' Gold / Expedition of Percy Fawcett to the Amazon (), was released as a part of the television series Mysteries of the Century (). Among other things, the film emphasizes the recent expedition of Oleg Aliyev to the presumed approximate place of Fawcett's last whereabouts and Aliyev's findings, impressions, and presumptions
