Credibility of Eyewitness Testimony in Robbery Homicide Cases: Supreme Court Upholds Conviction Despite Affida

In robbery with homicide cases, the prosecution often hinges on the testimony of a single eyewitness. When that witness's earlier sworn statements contradict his open-court testimony, a conviction may appear vulnerable. In People v. Mores, the Supreme Court clarified that such inconsistencies do not automatically destroy a witness's credibility. The Court upheld the conviction of Danilo Zamora for robbery with homicide, ruling that clear and positive testimony in court outweighs flawed affidavits.

The Facts of the Case

On September 9, 1991, at around 2:00 a.m., three men entered the Caltex gasoline station in Calapan, Oriental Mindoro. They attacked Alex Montemayor, the night guard, who was sleeping on a table. The men stabbed him multiple times, opened a cabinet with an iron pipe, and took a plastic bedpan containing P10,455.00 in sales proceeds. Montemayor died from hemorrhage secondary to multiple stab wounds.

Virgilio Castillo, a 19-year-old bus washer who spent the night in the station's office, witnessed the crime. From inside a parked bus, he saw the three accused—Marcelino Mores, Danilo Zamora, and Ronnie Racuma—enter the office and attack Montemayor. Two other prosecution witnesses, Wilfredo Alegre and Cesar Gutierrez, corroborated parts of Castillo's account. Both identified Mores and Zamora as among the men they saw leaving the station or dividing money shortly after the crime.

The Issue on Appeal

Zamora appealed his conviction on two grounds. First, he argued that Castillo's two sworn statements were materially inconsistent. In the first affidavit, Castillo said Montemayor was already dead when he woke up and that he only suspected Mores and Racuma. In the second, he implicated Zamora and claimed to have witnessed the entire crime. Second, Zamora raised the defense of alibi, claiming he was in another town attending to his wife who was giving birth.

The Supreme Court's Ruling

The Court rejected both arguments and affirmed the conviction. On the issue of affidavit inconsistencies, the Court applied a settled rule: affidavits are generally inferior to open-court testimony. Affidavits are often not prepared by the affiants themselves but by others who use their own language. Being ex parte, they are frequently incomplete and inaccurate. These defects, however, do not by themselves destroy a witness's credibility.

What mattered was Castillo's demeanor and consistency when he testified in court. He positively identified both accused and gave a straightforward narration of the events. The defense had the opportunity to cross-examine him and impeach his credibility. The Court held that such testimony rendered the affidavit inconsistencies immaterial.

On the defense of alibi, the Court reiterated the rule that denials and alibis, unsubstantiated by clear and convincing evidence, cannot prevail over positive identification. Castillo, Alegre, and Gutierrez were disinterested witnesses with no apparent motive to lie. Their affirmative testimonies outweighed Zamora's self-serving denial.

The Penalty Imposed

The trial court found two aggravating circumstances: treachery (the victim was sleeping when attacked) and abuse of superior strength. Under the Revised Penal Code, the presence of two aggravating circumstances with no mitigating circumstance would warrant the maximum penalty of death. However, because the crime was committed while the 1987 Constitution suspended the death penalty and before its re-imposition under Republic Act No. 7659, the Court imposed reclusion perpetua instead. The Court also ordered Zamora and Mores to pay P50,000.00 as civil indemnity to Montemayor's heirs and P10,455.00 as actual damages to the station owner.

Practical Takeaways

• Affidavit inconsistencies are not fatal. A witness's earlier sworn statements may contain errors or omissions, but these do not automatically destroy credibility if the witness testifies clearly and consistently in court.
• Open-court testimony carries greater weight. Courts give more credence to testimony delivered under oath, subject to cross-examination, than to affidavits prepared outside court.
• Positive identification beats alibi. An alibi must be supported by clear and convincing evidence; otherwise, it cannot overcome the positive identification of credible witnesses.
• Witness demeanor matters. Trial courts observe witnesses firsthand, and appellate courts generally defer to their assessment of credibility absent any showing of error.
• Aggravating circumstances affect the penalty. Treachery and abuse of superior strength can raise the penalty to death, but the applicable law at the time of the offense determines what is actually imposed.
