In the months before an Indigenous leader was killed with a gunshot in the face in the Amazon reserve he had spent much of his life protecting, at least two efforts were made to warn Brazil’s government of the risks posed by illegal loggers in the region.

In April, members of the Guajajara Indigenous group went to the capital, Brasília, to plead for protection from loggers invading their land in the state of Maranhão. In August, the state’s head of human rights wrote to the federal police to say loggers were threatening the Guajajara in the Araribóia Indigenous Land.

But those warnings didn’t help Paulo Paulino Guajajara during a hunting trip with a friend in the Araribóia reserve on Friday, when they were ambushed by a group of five loggers working illegally in the area.

Laércio Guajajara, the friend, who was wounded has been released from the hospital . A logger was reported missing.
