Proof Beyond Reasonable Doubt Can Rest on Credible Witness Testimony Alone

The Supreme Court has long held that a conviction for a crime can rest on the credible testimony of a single eyewitness. In People v. Cariño (G.R. No. 146436, September 30, 2002), the Court affirmed this principle, ruling that proof beyond reasonable doubt does not require overwhelming evidence—only evidence that is credible, consistent, and sufficient to convince a reasonable mind of the accused's guilt.

The case clarifies important rules on witness credibility, the nature of corpus delicti in murder cases, and the damages recoverable by the heirs of a murder victim. It is a useful guide for anyone seeking to understand how Philippine courts weigh evidence in criminal cases.

The Facts of the Case

On the evening of April 12, 1996, Mario Dispo was walking in Bolinao, Pangasinan, when Paquito Cariño invited him to accompany him to the Puericulture Center inside Dewey Elementary School. After waiting about thirty minutes, Mario went looking for Paquito and saw him from about fifteen meters away, standing before a waiting shed. The shed was illuminated by a fluorescent bulb about seven paces away.

Mario saw Paquito stab Rolly Dispo, his cousin, who appeared to be asleep on a bench. Rolly's mother discovered his body that same night. An autopsy revealed five stab wounds, four of which were fatal.

At trial, Paquito denied involvement and claimed he saw two other men commit the crime. He said he fled to Quezon province days later out of fear. The trial court convicted Paquito of murder, sentencing him to reclusion perpetua, but acquitted his co-accused relative.

The Issue on Appeal

Paquito argued that the prosecution failed to prove his guilt beyond reasonable doubt. He pointed to the supposed failure to present the doctor who performed the autopsy and the medico-legal report. He also argued that Mario's testimony was unreliable because Mario was a relative of the victim and had allegedly given inconsistent statements.

The Court's Ruling

The Supreme Court affirmed Paquito's conviction. The Court emphasized that trial courts are in the best position to assess witness credibility, having observed their demeanor and conduct firsthand. Unless there are compelling reasons to overturn such findings—none existed here—the appellate court is bound by them.

Mario's testimony was categorical and unimpaired. He had a clear view of the crime scene from a short distance, under adequate lighting. His relationship to the victim did not automatically taint his credibility, as no law disqualifies relatives from testifying if they are competent.

The Court also corrected a common misconception: corpus delicti in murder refers to the fact that a person was killed and that someone is criminally responsible—not to the autopsy report itself. In any case, the doctor who performed the autopsy did testify, corroborating Mario's account.

Finally, Paquito's flight from the area shortly after the incident weighed heavily against him. The Court found his alibi and his claim that he knew the real killers to be a "wild goose chase."

Treachery and Damages

The Court ruled that treachery qualified the killing as murder. The victim was drunk and unconscious, possibly sleeping, and therefore helpless and unable to defend himself. This made the attack alevosia, or treachery.

The Court reduced the civil indemnity from P75,000.00 to P50,000.00, consistent with prevailing jurisprudence at the time, and added P50,000.00 in moral damages for the heirs' pain and suffering.

Practical Takeaways

• A single credible eyewitness can be enough to convict, even without motive, an autopsy report, or physical evidence linking the accused to the crime.
• Trial courts' findings on witness credibility are given great weight and are rarely overturned on appeal.
• Relationship to the victim does not disqualify a witness or automatically make testimony suspect.
• Flight from the scene or jurisdiction can be strong evidence of guilt.
• In murder, corpus delicti is the fact of the killing and the accused's criminal responsibility—not the autopsy report.
