Regivaldo Pereira Galvao was recently seen at the site of the 2005 murder. He is accused of pressuring peasants into giving him their property rights according to prosecutor Felicio Pontes. The 7,400 acres of land in dispute is known as "Lot 55" in the Amazon.
Charges against Galvao include charges of land fraud and slavery. He is already charged with conspiracy to murder because of sister Stang's death. Sister Stang had been an advocate for the rights of landless peasants by giving them access to public land and promoting sustainable farming practices. She helped create a land distribution project, the Project for Sustainable Development (PDS), which had the support of the Brazilian government.
