G.R. No. 130523 ; January 29, 2002
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. GARIO ALBA alias “MARIO ALBA”, accused-appellant.

FACTS

The prosecution’s evidence established that on January 31, 1993, in Pamplona, Negros Oriental, accused-appellant Gario Alba stabbed Ricky Aguilar to death. Eyewitnesses Esterlito Aniñon and Roland Ybasan testified that they saw the incident while they and the victim were having a drinking session. They stated that Alba, without any provocation, approached Aguilar from behind and stabbed him once with a knife, the blow penetrating the victim’s back and exiting his chest. The victim died from the wounds. Dr. Quintin Bascos, who conducted the post-mortem examination, confirmed the nature and location of the fatal injuries.
The defense, however, presented a different version. Alba claimed he acted in self-defense. He testified that he was merely passing through the area when the victim, Ricky Aguilar, accosted and boxed him. Alba alleged that he saw Aguilar about to pull out a knife, prompting him to preemptively stab Aguilar twice with his own hunting knife. Defense witnesses Ricardo Imbo and Wilfredo Jabar Rodriguez corroborated parts of Alba’s account, particularly the initial assault by Aguilar and Alba’s subsequent surrender.

ISSUE

The core issue is whether the killing was attended by treachery to qualify it as murder, or if the appellant’s claim of self-defense is credible, or if the crime committed is homicide.

RULING

The Supreme Court modified the trial court’s decision, convicting Alba of Homicide instead of Murder. The Court found the prosecution witnesses credible and consistent in their narration that Alba stabbed the unarmed victim. The claim of self-defense was rejected. For self-defense to prosper, the accused must prove unlawful aggression, reasonable necessity of the means employed, and lack of sufficient provocation. Here, Alba failed to prove unlawful aggression. The testimony of defense witness Imbo was deemed unreliable as he was positioned 50 meters away and could not have clearly seen the alleged boxing incident or the victim reaching for a knife. The number, location, and trajectory of the wounds (one fatal stab penetrating the torso) also contradicted a close-quarters struggle and indicated a determined attack.
However, the Court ruled that treachery was not sufficiently established. The qualifying circumstance of treachery requires that the means of execution be deliberately and consciously adopted to ensure the offense without risk to the assailant. The prosecution evidence showed the attack was sudden, but it did not conclusively prove that Alba deliberately employed a method to render the victim defenseless. The attack from behind, while indicative of opportunity, did not per se establish the deliberate and calculated mode of attack required for treachery. Absent this qualifying circumstance, the crime is Homicide. The penalty was imposed considering the mitigating circumstance of voluntary surrender and the aggravating circumstance of treachery (which, while not qualifying, was considered as generic). The Court awarded civil indemnity, moral damages, and exemplary damages.
