José Belisario Carreño Calderón died that day at 21:00 hours, at the Bulnes bridge over the Mapocho River, from a craniocerebral gunshot wound, as recorded in the Medical Death Certificate from the Legal Medical Institute.

According to witnesses, José Carreño, a militant of the Partido Socialista and a member of President Salvador Allende's Personal Guard (GAP), was part of the group of GAP members, under the command of Domingo Blanco Tarrés, who were detained by Carabineros officers while attempting to enter the Presidential Palace on the morning of September 11, 1973.

The case of Domingo Blanco Tarrés was recorded as a victim of human rights violations in the report of the Comisión Nacional de Verdad y Reconciliación.

In the days that followed, his relatives learned of his death at the Legal Medical Institute, but they were unable to recover his remains because he had been buried, without their knowledge, in Patio Nº29 of the General Cemetery of Santiago.

Based on the evidence gathered and the investigation conducted by this Corporation, the Superior Council reached the conviction that José Belisario Carreño Calderón was detained and executed outside of any legal process. For this reason, it declared him a victim of human rights violations.*

────────────────────────* Subsequent to the qualification of this case, on October 27, 1994, the Twenty-Second Criminal Court of Santiago issued a resolution in the investigation being conducted regarding illegal inhumation in Patio Nº29 of the General Cemetery, corroborating that Autopsy Protocol Nº2727/73, in the name of José Belisario Carreño Calderón, belonged to him and ordered his remains to be delivered to his relatives.
