Earlier this month, environmental activist, Telésforo Odilo Pivaral Gonzalez, was killed by unknown assailants who shot him five times. The father of six children (ages 1-11), Pivaral Gonzalez had actively opposed a conflict-ridden Escobal silver mine project run by Canadian company, Tahoe Resources, and its local subsidiary, Minera San Rafael SA. 

Twenty four organizations, including Oxfam, have called for the Guatemalan government to investigate the killing of Pivaral Gonzalez, who was a member of the local group known as the Committee for the Defense of Life and Peace of San Rafael Las Flores. Pivaral Gonzalez was just 33. 

"[Pivaral Gonzalez] participated in actions protesting the establishment and expansion of mining projects in the region, and supporting municipal consultations of residents and peaceful actions of communities," according to the Campaign to Defend Life and Rights: We are Human Rights Defenders. 

Opposition to the massive silver mine, which began commercial operations last year, runs high in the region due to environmental fears, such as water pollution. The mining company has requested 16 licenses to explore for minerals in an area covering 2,400 square kilometers (960 square miles). Some of the communities in this agricultural area affected by the mine (or likely to be by its proposed expansion) have held votes, expressing their opposition to mining. Following one such referendum in 2013, the government sent in the military, and later falsely accused 17 people well known for their opposition to the silver mine of violent crimes.

Last year, seven Guatemalan men filed a lawsuit against Tahoe Resources in Canada, alleging that they had been shot during a protest in April, 2013 by Tahoe's private security team. The lawsuit alleges that Tahoe's local security manager, Alberto Rotondo, ordered the shooting. The trial is currently ongoing in British Colombia.
