The last survivor of an uncontacted tribe from the Brazilian Amazon lives alone. He is thought to be about 40 years old. He uses a bow and arrow, and once shot a man who was trying to communicate with him in the chest. He doesn't wear clothes, and he digs 5-foot-deep rectangular holes (which serve "no apparent purpose") in the thatch huts he builds. He grows vegetables, hunts for wild game, and collects honey from stingless(!) bee colonies.
He was first seen in 1996 and has been evading loggers ever since.

They first became aware of his existence nearly 15 years ago and for a decade launched numerous expeditions to track him, to ensure his safety, and to try to establish peaceful contact with him. In 2007, with ranching and logging closing in quickly on all sides, government officials declared a 31-square-mile area around him off-limits to trespassing and development.
