Case Summary (G.R. No. 104664)

Petitioner / Respondent

Plaintiff-Appellee: People of the Philippines (Prosecution); Accused-Appellant: Elyboy So (convicted and appealing).

Key Dates

Crime charged: on or about June 3, 1991 (information dated June 10, 1991); Appellant pleaded not guilty on July 19, 1991; Trial court decision convicting appellant issued January 17, 1995; Appeal decision referenced here rendered August 28, 1995. Because the decision date is 1990 or later, the 1987 Philippine Constitution is the constitutional framework applicable to the decision.

Applicable Law

Primary substantive provision applied: Article 248, Revised Penal Code (murder qualified by treachery). Penal presumptions and burden issues referenced against constitutional presumption of innocence and procedural rules as interpreted after the 1987 Constitution. Exempting circumstance of insanity invoked and assessed under Article 14(16), Revised Penal Code, and related jurisprudence cited by the Court.

Procedural History

Appellant was charged by information for murder with allegations of intent to kill, treachery and evident premeditation. After trial, the Regional Trial Court, Manila, Branch XLIX, found appellant guilty of murder qualified by treachery and sentenced him to reclusion perpetua and ordered P50,000 indemnity to the heirs; the appellant appealed, raising five assigned errors contesting credibility findings, self-defense, treachery, insanity as exempting circumstance, and the conviction itself. The Supreme Court denied the appeal and affirmed the trial court judgment.

Prosecution’s Factual Narrative

On the evening of June 2–early morning June 3, 1991, appellant socialized with relatives and companions in Sta. Mesa, consumed alcohol, and later, at about 4:00 a.m., while victim Mario Tuquero and Emy were waiting for a taxi, appellant suddenly appeared from behind and stabbed Mario multiple times with an 11-inch fan knife. Emy testified that appellant first stabbed the victim in the back, Mario slipped and fell face up, and appellant then repeatedly stabbed the anterior portions of Mario’s body despite Emy’s pleas. Mario sustained eighteen stab wounds on different parts of his body, four of which were fatal. Appellant fled to an alley but later surrendered to police; the weapon was recovered and surrendered by the barangay chair.

Appellant’s Version and Defenses Raised at Trial

Appellant asserted that an earlier altercation and perceived insults by relatives motivated his initial flight. He claimed that Mario later attacked him with a knife at the corner of Pureza and Magsaysay Streets, that Mario’s thrusts were slow, and that appellant was able to wrest the knife from Mario and then stabbed Mario repeatedly in purported self-defense. Appellant also invoked an exempting circumstance of insanity based on a prior confinement at the National Center for Mental Health (NCMH) in 1985 and introduced testimony from Dr. Omer Galvez concerning past psychosis and the possibility of recurrence.

Issues on Appeal Presented by Appellant

  1. Trial court erred in overruling self-defense.
  2. Trial court erred in discrediting appellant’s testimony as improbable and implausible.
  3. Trial court erred in finding treachery.
  4. Trial court erred in disregarding the exempting circumstance of insanity.
  5. Trial court erred in convicting appellant of murder.

Standard on Witness Credibility and Appellate Review

The Court reiterated the settled rule that when credibility is at issue, the trial court’s findings are entitled to great weight because it observed witnesses firsthand and assessed deportment; appellate courts will not ordinarily disturb such findings unless the trial court plainly overlooked substantial facts that would affect the result. The Court rejected appellant’s contention that the prosecution witness Emy So was so biased by relationship to the victim or family grudge as to render her testimony unreliable; the Court held that mere relationship to the victim does not automatically impair credibility and that Emy’s testimony was not inherently improbable.

Burden of Proof When Self-Defense Is Pleaded

While the Constitutionally-based presumption of innocence normally places the burden on the prosecution to prove guilt beyond reasonable doubt, the Court explained the well-established rule in Philippine jurisprudence that, once self-defense is asserted, the burden shifts to the accused to prove the elements of self-defense (unlawful aggression by the victim, reasonable necessity of the means employed, and lack of sufficient provocation by the accused) by clear and convincing evidence. The accused must rely on the strength of his own evidence rather than the weakness of the prosecution’s case.

Court’s Analysis of Self-Defense Claim

The Court found appellant’s account inconsistent and implausible. Appellant testified both that Mario’s thrust was slow (allowing appellant to wrest the knife) and that the incident happened suddenly and fast; the Court treated this contradiction as undermining appellant’s claim. Even assuming initial unlawful aggression by Mario, the Court held that once appellant wrested the knife from Mario, unlawful aggression had ceased and there was no longer a basis for continued deadly force. The trial court’s observation that there was no evidence Mario attempted to retrieve the knife or persist in aggression after appellant obtained it further negated the justification of continued stabbing.

Physical Evidence, Number and Location of Wounds, and Treachery

The necropsy showed eighteen stab wounds, four fatal, with several wounds located on posterior aspects consistent with a sudden attack from behind and multiple anterior wounds consistent with repeated stabbing as the victim lay on his back. The Court emphasized that such a large number of wounds, their nature and distribution, and the absence of any injury to appellant, negated the plausibility of self-defense and indicated a determined effort to kill. Given the sudden attack from behind and the manner of execution that afforded the attacker safety from resistance, the facts supported the finding of treachery under Art
