Witness Credibility and Treachery: Key Lessons from a Philippine Murder Conviction

The Supreme Court's 2017 decision in People v. Dayaday offers practical guidance on two recurring issues in Philippine murder cases: how courts evaluate the credibility of an eyewitness who is related to the victim, and when the qualifying circumstance of treachery converts a killing into murder. The ruling affirms the conviction of Roque Dayaday for the murder of Basilio Gallenero and clarifies how trial courts' factual findings are treated on appeal.

The Facts of the Case

On the evening of October 27, 2005, around 10 o'clock, Basilio Gallenero and his son Alex were walking home along a road in Norala, South Cotabato after attending a wedding celebration. Suddenly, Roque Dayaday shot Basilio in the back four times. Alex easily recognized the assailant because the area was well lit and he was only about ten meters away.

Alex ran away in fear and later reported the incident to his uncle and to police. The postmortem examination showed the victim suffered four gunshot wounds and one stab wound, causing his death.

Roque denied the accusation and presented the defense of alibi. His brother and another witness testified that Roque was in a kitchen preparing food for the wedding from 5 o'clock in the evening until 3 o'clock the following morning, and never left.

The Issue Before the Court

The sole issue was whether the Court of Appeals erred in affirming Roque's conviction for murder. Roque questioned the credibility of Alex, arguing that Alex was biased because of his relationship to the victim. He also pointed to alleged inconsistencies: Alex's affidavit mentioned other witnesses but he testified in court that he was the sole witness, and Alex said his father was shot four times while the postmortem report indicated seven gunshot wounds.

The Court's Ruling on Witness Credibility

The Supreme Court dismissed the appeal. It reiterated the settled rule that when issues involve witness credibility, the trial court's findings are given high respect, if not conclusive effect. This is because the trial court has the unique opportunity to observe the demeanor of witnesses and is in the best position to discern whether they are telling the truth.

The Court cited People v. Montemayor in ruling that a witness's relationship to the victim does not, by itself, give rise to a presumption of bias. On the contrary, it would be unnatural for a relative interested in vindicating the crime to charge someone other than the real culprit. Relatives of victims have a natural knack for remembering the face of the attacker and are more concerned with obtaining justice.

The alleged discrepancy in the number of gunshot wounds was resolved by the Court's explanation: the postmortem report showed four entry wounds and three exit wounds, meaning three perforating gunshots and one penetrating gunshot. This coincides with Alex's testimony that his father was shot four times.

As for the inconsistency between Alex's affidavit and his court testimony, the Court cited People v. Yanson in holding that discrepancies between a sworn statement and open court testimony are not fatal. Ex parte affidavits are almost always incomplete and are generally considered inferior to testimony given in open court. Such honest inconsistencies may even strengthen a witness's credibility because they erase suspicion that the testimony was rehearsed.

Treachery as a Qualifying Circumstance

Under the Revised Penal Code, murder is committed when a person is killed, the accused killed that person, the killing was attended by any of the qualifying circumstances enumerated in the law, and the killing does not constitute parricide or infanticide. Among these qualifying circumstances is treachery, which the law recognizes as elevating a killing to murder.

The Court found treachery present. Treachery exists when a victim is set upon without warning, as when the accused attacks from behind, or when the attack is sudden and unexpected and the victim is unable to defend himself, thus ensuring the execution of the criminal act without risk to the assailant.

Here, the evidence showed the attack came from behind and was sudden, deliberate, and unexpected. The victim was walking home with his son, completely unaware of any threat. The use of a firearm showed deliberate intent to kill, and the location and number of gunshot wounds rendered the victim defenseless.

The Penalty and Damages

Since only treachery was proven—and the aggravating circumstances of evident premeditation and illegal possession of firearms were not—the proper penalty was reclusion perpetua. The Court modified the damages awarded, following People v. Jugueta: P75,000 as civil indemnity, P75,000 as moral damages, and P75,000 as exemplary damages, plus the P30,000 for actual expenses. All monetary awards earn 6% interest per annum from finality of the judgment until fully paid.

Practical Takeaways

• Trial court findings on credibility are rarely overturned on appeal. The trial court's unique position to observe witnesses gives its factual findings great weight, especially when affirmed by the Court of Appeals.
• A witness's relationship to the victim does not impair credibility. Absent proof of improper motive, a relative's testimony may even be more credible because of the natural interest in seeing justice done.
• Minor inconsistencies do not destroy a witness's testimony. Discrepancies between an affidavit and open court testimony, or minor details, may actually strengthen credibility by showing the testimony was not rehearsed.
• Treachery is established by the manner of attack. A sudden, unexpected attack from behind that leaves the victim defenseless qualifies a killing as murder under the Revised Penal Code.
• Alibi is a weak defense when physical impossibility is not shown. If the accused could have been at the crime scene, alibi generally fails against positive identification.
