Manuel Estanislao Negrete Hernández died that day at 18:00 hours, at the Hospital de Curicó, due to sepsis originating from a thoracic and cranial gunshot wound, as recorded in the Medical Death Certificate from the Legal Medical Institute.

According to eyewitness accounts, on September 19, 1973, Manuel Negrete was drinking with some friends at a business in the town of Sagrada Familia. A fight broke out at the location, which led to the arrival of three carabineros, who arrived firing their weapons.

One of the shots struck Manuel Negrete, who fled while wounded into the interior of a farm. There, he was surprised by the uniformed officers, who fired numerous shots at him again at point-blank range. Hours later, he was transported to a hospital center, where he passed away weeks later.

Considering the evidence gathered in the investigation conducted by this Corporation, the Superior Council declared Manuel Estanislao Negrete Hernández a victim of human rights violations committed by State agents who made irrational use of force.
