Marcia Elena Miranda Díaz died that day at 19:20 hours, at the Regional Hospital of Concepción, due to extensive burns, by suicide, according to the Medical Death Certificate from the Legal Medical Institute.

According to witness statements provided during the judicial proceedings, the events that culminated in her death began on September 5, 1984, the date on which she was detained by plainclothes carabineros while she was erasing slogans written against the Parish Priest of Lota.

After being detained for a couple of hours, she was released. On October 10, at approximately 19:30 hours, she was abducted by civilians who beat her, requiring her to be treated at the Hospital for the injuries caused.

On October 31, she was abducted again by unknown individuals; they took her to a property located in Playa Negra, where they tried to force her to sign an incriminating statement against the aforementioned Parish Priest. As she refused to do so, she was beaten, humiliated, and they inserted a wire into her vagina, which was later removed at the Hospital.

Days later, she appeared at the Human Rights Pastoral of the Archbishopric of Concepción to make her situation known and request help. A preventive writ of amparo was filed on her behalf, in which her fear of being detained and physically assaulted again was expressed.

On November 23, she appeared in front of the Church of Lota doused in paraffin and set herself on fire. Transferred to the medical facility, she passed away hours later due to the severe burns she suffered.

Considering the evidence gathered and the investigation conducted, the Superior Council reached the conviction that Marcia Elena Miranda Díaz made the decision to take her own life, driven by the fear of again suffering the torture, humiliation, and beatings to which she was subjected by State agents. For this reason, it declared her a victim of human rights violations.
