G.R. No. L-28710 April 22, 1977
THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. CONCESO ACLO, VICENTE ACLO, and MACARIO PITO, defendants, CONCESO ACLO, defendant-appellant.

FACTS

The case stemmed from a violent incident during a customary marriage gathering in Barrio Cahayag, Tudela, Misamis Occidental, on May 27, 1967. The appellant, Conceso Aclo, was present as a kitchen helper for the party hosted by the prospective bride’s family. During the event, a commotion erupted in the kitchen. The victim, Valentin Acuram, an uncle of the bride, emerged wounded and, in his dying declaration to the barrio captain and later to police, identified “the son of Bandoy” (Conceso Aclo) as his assailant. Acuram succumbed to multiple stab wounds the following day. An information for murder, qualified by treachery, was filed against Conceso Aclo, Vicente Aclo, and Macario Pito. After trial, the Court of First Instance convicted Conceso Aclo of murder and sentenced him to reclusion perpetua, while acquitting his co-accused. Conceso Aclo appealed, pleading self-defense and contesting the finding of treachery.

ISSUE

The core issue is whether the killing of Valentin Acuram constituted murder qualified by treachery or the lesser crime of homicide, and whether the appellant successfully proved self-defense.

RULING

The Supreme Court modified the conviction from murder to homicide. The Court held that the prosecution failed to prove the qualifying circumstance of treachery (alevosia) beyond reasonable doubt. The evidence did not clearly establish that the attack was executed suddenly and without warning, denying the victim any chance to defend himself. Witness accounts indicated the victim had rushed towards the appellant in the kitchen, uttering a challenge. This scenario negated the element of surprise or helplessness on the victim’s part required for treachery. The Court also rejected the plea of self-defense. By invoking it, the appellant assumed the burden of proving its elements—unlawful aggression, reasonable necessity of the means employed, and lack of sufficient provocation. The appellant’s own testimony and the evidence on record were insufficient to clearly and convincingly establish these requisites. Consequently, with self-defense unproven and treachery absent, the crime is properly homicide. Applying the Indeterminate Sentence Law and with no aggravating or mitigating circumstances, the Court sentenced appellant to an indeterminate penalty of 8 years and 1 day of prision mayor, as minimum, to 14 years, 8 months, and 1 day of reclusion temporal, as maximum. The civil indemnity was increased to P12,680.00. The judgment was affirmed as modified.
