The man found dead had resisted all attempts to reach him, setting traps and shooting arrows at anyone who came too close.

The man found dead in the Brazilian part of the Amazon is, according to British newspapers Guard perhaps an unknown native tribe. The man is believed to be the last survivor of the tribe.

This lonely and mysterious man is known only as Índio do Buraco, which means “Native Man in the Hole”. He got his nickname because he spends most of his life hiding in the holes he digs in the ground.

Indigenous activists suspect that his tribe was wiped out when people seeking to exploit the area’s rich natural resources gave the tribe “sugar” as gifts – mixed with rat poison.

Over the decades, the man has seen his realm invaded, and his friends and family killed. He had rejected all the countless attempts to contact her.

If people came too close, he had set a trap and shot arrows at them.

“After suffering horrific massacres and invasions of tribal lands, refusing contact with outsiders is his best chance for survival,” said Sarah Shenker, an activist for the global movement for tribal peoples, Survival International.

– He was the last of his tribe, and is considered another tribe that was exterminated – not lost, as some say. Going extinct is a more active genocide than disappearing, he added.

We don’t know much about the man, other than that his refusal to communicate with the outside world has garnered worldwide attention.

– He doesn’t trust anyone because he has had many traumatic experiences with non-indigenous people, says retired adventurer Marcelo dos Santos, who is in charge of monitoring the man’s rights on behalf of Brazil’s national indigenous foundation, Funai.

Dos Santos said he and other Funai representatives had left strategically placed gifts of tools, seeds and food for the man. But gifts are always refused.

They believe the skepticism stems from a bounty in the 1980s where ranchers operating illegally gave the tribe sugar containing rat poison. Believed to have killed everyone except the “hole man”.

It must have been the representative from Funai who accompanied the man from a distance who found his body in the hammock. He’s probably been there a long time, because the decomposition process is already underway. Representatives of Funai believe the man was aware that death awaited, as he had placed colorful feathers all over his body, which may have looked like a ritual to prepare for death. The mystery man is believed to be around 60 years old.

Indigenous organizations believe there are between 235 and 300 living tribes, but it is difficult to give an exact number, as some tribes have had very little contact with settler societies and our modern world.

There are at least 30 groups believed to live deep in the jungle of which we know almost nothing about how many there were, what language they spoke or what their culture was like.

Funai first learned of the man in the mid-1990s when indigenous activists discovered small patches of land that had been destroyed by sedentary encroaching farmers and the remains of houses they assumed the farmers had swept away with tractors. They also found large hand-dug holes in an area along the border between Brazil and Bolivia. This treaty is still under attack by those who wish to supply themselves with significant natural resources.

When Funai found the man, they put up a fence so he had an area where he could live unhindered. In 1997, they received official approval to establish the Tanaru nature reserve.
