After spending 26 years in isolation, the last surviving member of the tribe that inhabited Brazil's Tanaru Indigenous Territory has passed away. He was known as the "Man of the Hole" because of the numerous holes he dug around his territory. Some of the holes had sharp spikes in them, likely used for hunting or protection. On Aug. 23, his body was found by members of Funai — the National Indian Foundation in Brazil. It appears that he died from natural causes in a hammock outside of his home. According to The New York Times, this is the first recorded disappearance of a so-called uncontacted tribe.
