In a case being compared to that of Chico Mendes, the Amazon defender killed in 1988, US missionary Sister Dorothy Stang was shot dead by unknown assailants at a remote jungle settlement near Anapu in the Brazilian state of Para Feb. 12. Stang, 74, of the Sisters of Notre Dame de Namur, had been a campaigner for human rights and forest protection in the Amazon for three decades, and had reported receiving numerous death threats from land speculators and cattle barons.
