G.R. No. 117689 . January 30, 1997.
The People of the Philippines, plaintiff-appellee, vs. Eliseo Alvarez y Villalva, Vilma Alvarez y Magada, and Alberto Alvarez y Magada, accused-appellants.

FACTS

Accused-appellants, spouses Eliseo and Vilma Alvarez and their son Alberto, were charged with the murder of Benito Paez and the frustrated homicide against his wife, Rosalinda Paez. The prosecution evidence established that on October 12, 1993, in Barangay Masaguisi, Sta. Cruz, Marinduque, the appellants, armed with bolos and an axe, attacked the victims. The incident began when the Paezes’ dog barked at Eliseo, who became irate. While Benito and Rosalinda were threshing palay inside their hut, Eliseo, coming from behind, suddenly hacked Benito on the shoulder. Vilma then stabbed Benito on the chest. Rosalinda attempted to intervene but was attacked by Vilma, sustaining injuries to her hand and face. Witness Jimmy Ornos corroborated Rosalinda’s account, adding that Alberto later joined the assault, striking Benito with an axe. Benito suffered multiple fatal wounds.
The appellants presented a different version, claiming self-defense. Eliseo testified that he and Alberto were merely passing by when Benito, without provocation, attacked him with a bolo. He alleged that he wrestled the bolo from Benito and used it to defend himself. Vilma claimed she only intervened to help her husband. The trial court convicted Eliseo and Vilma of murder and Vilma of attempted homicide, while Alberto’s trial was suspended for psychiatric examination.

ISSUE

The core issues were: (1) whether the appellants successfully proved self-defense, and (2) whether the qualifying circumstance of treachery was present to sustain a conviction for murder.

RULING

The Supreme Court affirmed the convictions. On the first issue, the Court held that the appellants failed to prove self-defense by clear and convincing evidence. The legal logic requires that one invoking self-defense admits the killing and must prove the justifying circumstances of unlawful aggression, reasonable necessity of the means employed, and lack of sufficient provocation. The appellants’ narrative was inconsistent and improbable. The nature, number, and severity of Benito’s wounds—ten fatal injuries including a severed arm and a skull fracture—were completely disproportionate to a scenario of mere defense and instead indicated a determined effort to kill. The trial court correctly found the prosecution witnesses credible and their straightforward account more aligned with the evidence.
On the second issue, the Court ruled that treachery (alevosia) was duly established. The attack was sudden and unexpected. Benito was attacked from behind by Eliseo while he was engaged in threshing palay, rendering him unable to mount any defense. The successive attacks by Vilma and Alberto followed immediately, ensuring the victim’s helplessness. An unexpected and sudden attack under circumstances that render the victim unable and unprepared to defend himself constitutes treachery. Thus, the crime was properly qualified as murder. The penalty and civil liabilities imposed by the trial court were affirmed.
