Last update June 30 at 11:30 am All parties - the prosecution, private accusers, and the defense presented their closing remarks. The prosecution argued that they presented sufficient evidence to demonstrate that David Castillo is guilty of being the intellectual author of Berta Cáceres’s murder. The murder was carried out because Berta had caused significant economic losses for DESA and had caused the dam construction company, Sinohydro to pull out of the Agua Zarca project.
