On 28 June 2017, the closing arguments of the trial began against 18 community leaders related to the mobilization organized by Aymara communities - known as “Aymarazo” - that took place in Puno in 2011. At that time, the communities organised several protests against the proposed Bear Creek Mining Corp.'s Santa Ana mining project. In June, 8 cases were withdrawn due to lack of evidence. However, the other 10 community leaders faced sentences ranging from 16 to 28 years in prison and fines totaling over two million dollars. The human rights defenders still facing prison sentences are Walter Aduviri Calizaya, Patricio Illacutipa Illacutipa, Rufino Machaca Quinto, Domingo Quispe Tancara, Javier Pari Sarmiento, Eddy Uriarte Chambilla, Gregorio Ururi Fernandez, Severo Efrain Iturry Gandarrillas, Gilver Chura Yupanqui and Felix Illacutipa Mamani.
