G.R. No. 225745 , February 28, 2018
The People of the Philippines, Plaintiff-Appellee vs. Arsenio Endaya, Jr. y Perez, Accused-Appellant

FACTS

Accused-appellant Arsenio Endaya, Jr. was charged with Parricide for killing his wife, Jocelyn Quita-Endaya, and Murder for killing his mother-in-law, Marietta Bukal-Quita, on November 21, 1999. The prosecution’s evidence, primarily from Jocelyn’s son Jennifer de Torres, established that Endaya went to the house where Jocelyn and Marietta resided. De Torres testified that upon hearing shouts, he saw Endaya stabbing Jocelyn inside a comfort room. After arming himself, De Torres saw Endaya stab Marietta outside the room before fleeing. Both victims sustained multiple stab wounds and were pronounced dead on arrival at the hospital.
Endaya admitted the killings but claimed self-defense. He testified he went to the house to persuade Jocelyn to return home, which led to an argument. He alleged that De Torres suddenly attacked him with a bolo, causing injuries that blurred his vision. In defending himself, he claimed he grabbed a knife and, due to the darkness, mistakenly stabbed Jocelyn and later Marietta when they blocked his path. He surrendered to police the following day.

ISSUE

Whether the Court of Appeals correctly affirmed the trial court’s finding of guilt, rejecting Endaya’s claim of self-defense.

RULING

The Supreme Court affirmed the conviction for Parricide and Homicide (modified from Murder), upholding the lower courts’ rejection of the self-defense plea. The legal logic is anchored on the principle that self-defense is an affirmative allegation; the burden of proof rests on the accused to establish its elements by clear and convincing evidence. These elements are: (1) unlawful aggression by the victim; (2) reasonable necessity of the means employed to prevent or repel it; and (3) lack of sufficient provocation on the part of the person defending himself.
Endaya’s claim failed on all counts. First, the Court found his narrative of unlawful aggression from De Torres unconvincing and unsupported by the physical evidence. The anatomical sketch he presented showed only minor injuries inconsistent with a frenzied hacking attack. Second, the nature and number of wounds inflicted—four stab wounds on each unarmed victim—negated the reasonable necessity of the means used. The multiple wounds indicated a determined assault, not a spontaneous, reasonable act of repelling an attack. Third, his claim of mistaken identity due to darkness was deemed implausible, as he was familiar with the victims and the location. The trial court’s assessment of witness credibility, which favored the prosecution’s straightforward account over the accused’s improbable version, was accorded finality. The Court thus held that the prosecution successfully proved Endaya’s guilt beyond reasonable doubt. The mitigating circumstance of voluntary surrender was properly appreciated, modifying the penalty for the killing of Marietta from Murder to Homicide due to the failure to prove treachery. Civil liabilities were awarded accordingly.
