G.R. No. 98425-26 - People vs. Aguilar

On the evening of August 1, 1989, at around 8:30 p.m., in Sitio Simsiman, Barangay Marguez, Municipality of Esperanza, Sultan Kudarat, a tragic incident occurred.
Marcelino Aquino, who was shelling corn under his house with his mother, Lilia Aquino, was suddenly shot in the abdomen. He could only cry out “Nay” before falling dead.
Three additional gunshots were fired from different directions, immediately followed by the explosion of a hand grenade that injured Lilia Aquino, Ailleen (or Aileen) Aquino, and Argie Aquino.

Based on the claim by Ailleen Aquino and her husband, Salustiano Aquino, that one of the perpetrators was Nonong Aguilar (the Station Commander of Esperanza), two separate criminal complaints were filed for Murder and Multiple Frustrated Murder with the 4th Municipal Circuit Trial Court.
Nonong Aguilar was arrested on August 16, 1989, on the basis of the warrant issued in the first case.
An agreement between Aguilar’s counsel and the prosecution led to the withdrawal of Aguilar’s motion to fix bail bond, and the cases were subsequently transmitted to the Office of the Provincial Prosecutor.

On September 25, 1989, the Provincial Prosecutor filed two separate Informations in Branch 19 of the Regional Trial Court—one charging Murder (Criminal Case No. 1856) and the other charging Multiple Frustrated Murder (Criminal Case No. 1857).
The accusatory portions detailed that, in conspiracy with two unidentified companions, the accused participated in the shooting of Marcelino Aquino and the grenade explosion that injured the Aquino family members.

Testimonies by Salustiano Aquino and, on rebuttal, by Ailleen Aquino were central to the prosecution’s case.
Salustiano testified that he saw the accused, at only about one meter away, holding a firearm and allegedly pointing it towards Marcelino Aquino in the kitchen after the grenade explosion.
The prosecution’s narrative was supported by documentary evidence such as a death certificate and medical certificates, although the death certificate pointed only to one gunshot wound.

The accused, during arraignment on November 2, 1989, pleaded not guilty to both charges.
The defense presented witnesses including Crescencio Dolero, Dionisio Castor, Ricardo Aguilar, Pfc. Merly Sevilla, as well as the accused himself, who testified in sur-rebuttal.
In his defense, the accused asserted an alibi, claiming he was asleep at home until awakened by gun reports, and denied being present at the scene when the crime occurred.

The identification of the accused relied heavily on the testimonies of Salustiano Aquino and Ailleen Aquino.
A critical factual issue arose regarding the condition of the only source of light—a kerosene lamp—which was extinguished by the hand grenade explosion, thereby undermining the reliability of the witness identification.
Contradictions were evident between the physical evidence (notably the death certificate stating a single gunshot wound) and the witnesses’ accounts suggesting multiple shots.

Whether the positive identification of Nonong Aguilar by Salustiano and indirectly by Ailleen can be considered reliable given the compromised lighting conditions after the grenade explosion.
The impact of the extinguished kerosene lamp on the witnesses’ ability to clearly observe and later identify the accused.

Whether the prosecution established beyond reasonable doubt that the accused personally fired the fatal gunshot that killed Marcelino Aquino.
Whether there was sufficient evidence to support the allegation that the accused threw the hand grenade which caused injuries.
Whether, if multiple assailants were involved, there was valid proof linking the accused to either the first gunshot or the grenade explosion, or to a conspiracy with the unidentified accomplices.

Whether the trial court correctly applied the standard of proof beyond a reasonable doubt in evaluating the credibility of the identification evidence.
Whether the failure to discharge the burden of proof on the prosecution’s part mandates an acquittal of the accused.
