Victoriano Matus Hermosilla died that day from meningoencephalic contusion and craniocerebral trauma, as recorded in his Death Certificate. The registration of his death was carried out by resolution of the Military Court of Valdivia.

At that time, Victoriano Matus worked at the Panguipulli Forestry and Lumber Complex and, according to family members, he was detained in January 1974 by personnel from the Choshuenco Carabineros station.

According to testimony provided to the Corporation by a former police officer who served in that unit at the time, he was taken away by military personnel the following day, bound for Valdivia. The next day, carabineros found his body at the entrance to Máfil.

In October 1973, Matus had been detained at the Panguipulli Forestry and Lumber Complex and transferred to the Cazadores Regiment in Valdivia; after one month, he was released.

Considering the evidence gathered and the investigation conducted by this Corporation, the Superior Council reached the conviction that Victoriano Matus Hermosilla was executed while in detention, outside of any legal process. For this reason, it declared him a victim of human rights violations committed by State agents.
