According to eyewitnesses, he was detained by Carabineros officers on September 20, around 20:30 hours, while he was at the door of his home, located at Maule and Santa Elena. Neighbors in the area stated that he was executed in the early hours of September 21 on the side of the train tracks, between Lira and Padre Orellana streets, the place where his body was found.

Considering the evidence gathered and the investigation carried out by this Corporation, the Superior Council reached the conviction that Guillermo de Jesús Cáceres Pavez was extrajudicially executed by State agents while in detention. For this reason, it declared him a victim of human rights violations.
