Rolando Hugo Urbina Bravo died that day at 6:00 hours, in the Maipo River, due to a thoracic-cervical-facial gunshot wound with an exit projectile, as certified by the Medical Death Certificate from the Legal Medical Institute.

According to statements by his relatives, Rolando Urbina was reinstated into the Ejército on September 19, 1973, as a reservist at the Balmaceda Regiment in San Bernardo. On September 26, around 8:30 hours, the family received a telephone call informing them that Rolando Urbina's body was on the north bank of the Maipo River, in the Isla de Maipo sector.

Upon arriving at the site of the discovery, the relatives saw twelve other bodies of unknown young men next to Rolando Urbina's body. Rolando Urbina's body had a gunshot wound under the jaw, he was dressed in civilian clothes with all his documentation among his belongings, and around his neck, tied with wire, was a white handkerchief. Carabineros were at the scene and had dug holes in which they were burying the bodies.

The relatives had to carry out numerous procedures to recover the body and bury it in the Metropolitan Cemetery.

At the Balmaceda Regiment, they informed the family that Rolando Urbina's death had occurred as a result of an extremist attack while he was off duty. Upon reviewing the submission of victims that the Ejército presented to the Comisión Nacional de Verdad y Reconciliación, his name does not appear registered.

Considering the background information gathered and the investigation conducted, despite not having been able to establish the precise circumstances of his death, the Superior Council declared Rolando Hugo Urbina Bravo a victim of the political violence prevailing at the time of his death.
