José Raúl Quintul Muñoz died that day at 13:15 hours at the Hospital de Castro due to myocardial infarction and decompensated heart failure, as established by his death certificate.

According to witness statements, José Quintul, a socialist militant, was detained in March 1974 by Carabineros officers belonging to the Castro police station, who subjected him to repeated torture and mistreatment.

On April 21, 1974, he was transferred to the Chin-Chin Prison in Puerto Montt, a facility where he was seen in poor physical condition. He had difficulty walking and suffered from severe back and stomach pain. Nevertheless, he continued to be systematically interrogated.

Subsequently, he was taken to the preventive detention center in Castro, where he finished serving a sentence for violating the Arms Control Law. In this place, his pain worsened to the point of preventing him from walking, without him receiving adequate medical attention.

His family moved him to Santiago, where he underwent medical examinations and treatments for eight months without showing improvement. He passed away two years later.

Considering the gathered evidence, the Superior Council reached the conviction that the torture to which José Raúl Quintul Muñoz was subjected during his detention by State agents, as well as the lack of timely and effective medical attention, decisively influenced his death. For this reason, he was declared a victim of human rights violations.
