It's very sad as it sounds like some organization built up trust with him and that probably led him to being less cautious and killed by other people (because how he would tell the difference).
To let be or to interfere I guess is always a lose lose choice...
Do you have any reasons to suspect he was killed? The article says:
> He was found "lying down in the hammock, and ornamented [with macaw feathers] as if waiting for death". There were no signs of violence or any other disturbance before his corpse had been discovered by FUNAI.
