One year ago, Berta Cáceres was asleep in bed in La Esperanza, Honduras, when gunmen burst into the house and shot her. She died in the arms of Gustavo Castro, a Mexican environmental activist who was injured but pretended to be dead until the murderers had gone. Instead of being treated as a victim, Castro was regarded as a suspect and prevented from leaving the country. Members of the Council of Indigenous Peoples of Honduras (COPINH), which Cáceres led, were also interrogated. Eventually investigators turned their attention to those who had threatened to kill her in the preceding months. Seven arrests were made, but the people who ordered the murder were left untouched. Six weeks ago, Castro filed a petition against the Honduran government for the way it treated him and for its inaction in charging those behind the crime.
