FILE - In this Nov. 16, 2011 file image released by the Federal Public Ministry of Mato Grosso do Sul State, Nisio Gomes, a chief of the Kaiowa-Guarani Indian tribe in western Brazil, is seen two days before he was executed, in Mato Grosso do Sul state, Brazil. Gomes was the chief of the Brazilian tribe struggling to protect its land from ranchers. Masked men gunned him down in November; his body, quickly dragged into a pickup, has not been seen since.
