From the letter:
Dear Attorney General María Consuelo Porras Argueta:
We are writing to express our profound sadness and concern at the killing of human rights defender Ángel Estuardo Quevedo in the municipality of Santa Rosa de Lima on July 12, 2018. Estuardo resided in the municipality of Casillas and was a member of the Peaceful Resistance movement of Santa Rosa, Jalapa and Jutiapa. He played an important role in making visible broad community opposition to the Escobal silver mine, a Canadian mining investment project, owned by Tahoe Resources. Estuardo and his fellow human rights defenders have worked tirelessly and at great personal risk to raise awareness about the ways in which Tahoe and its subsidiary Minera San Rafael have violated their human rights.
Before his death, Estuardo spent considerable time in Guatemala City at the peaceful resistance camp set up outside the Constitutional Court to inform the public about the violations of Indigenous rights committed by Tahoe and Minera San Rafael. He was awaiting a crucial Constitutional Court ruling about the future of the Escobal mine when he was killed. Estuardo lived and died as a courageous human rights defender and was part of a community still facing terrible risks to stand up for their rights.
