Afterwards, he lived with them for over ten years, adopting their way of life and helping them with necessary medical supplies. Due to his help, the Enawene Nawe population rebounded from a low of 97 individuals to a population of over 430. Similar to Chico Mendes and Wilson Pinheiro, he died at the hands of cattle ranchers who were destroying the Amazon Rainforest.
