Eyewitness Inconsistency and Reasonable Doubt: Scrutinizing Witness Testimony in Murder Cases

In criminal cases, the prosecution must prove two things beyond reasonable doubt: that a crime was committed, and that the accused committed it. Even where the killing is undisputed, conviction cannot rest on an identification that is uncertain. The Supreme Court's decision in People v. Vargas (G.R. No. 208446, April 6, 2016) illustrates how serious inconsistencies in a lone eyewitness's account can create reasonable doubt and lead to acquittal.

The killing and the lone witness

On the evening of September 4, 2004, in San Jose del Monte City, Bulacan, Jojo Magbanua was shot and killed. The prosecution's case rested on a single eyewitness, Adolfo Lagac, who testified that he was inside a grocery store when he heard a gunshot and saw the bloodied victim run in. Two armed men then entered, approached the victim who was already on the ground, and one of them shot him.

Adolfo identified the appellants, Jonel Vargas and Jerienald Villamero, as the two assailants. He said Jonel fired the fatal shot while Jerienald merely stood beside him. The Regional Trial Court convicted both of murder, and the Court of Appeals affirmed with a modification on damages.

The problem with the identification

The defense pointed to a glaring inconsistency between Adolfo's sworn statement and his testimony in court. In his affidavit, taken twelve days after the shooting, Adolfo named six individuals who allegedly chased the victim, and he expressly said he could not remember who shot him. He explained that he was too scared to recall.

Two years later, testifying in court, Adolfo changed his account. He now said only two men chased the victim, and he pointed to Jonel as the gunman. Notably, the two men he identified were the only suspects arrested in connection with the crime.

What the Court ruled

The Supreme Court acquitted both appellants. While affidavits taken ex parte are generally inferior to testimony in open court, the Court held that this principle could not apply where the inconsistency concerns the very identity of the assailants — a crucial element of the crime.

The Court stressed that the discrepancy could not be dismissed as inconsequential. It cited People v. Rodrigo (586 Phil. 515, 2008), which instructs that great care must be taken when identification is made by a sole witness and the conviction depends entirely on the reliability of that identification. It also invoked People v. Flores (377 Phil. 1009, 1999), holding that serious and inexplicable discrepancies between a witness's sworn statement and testimony raise grave doubt on the witness's account.

Since no other evidence directly implicated the appellants, the Court found that the prosecution failed to prove authorship of the crime beyond reasonable doubt. A slight doubt as to the identity of the perpetrators must be resolved in favor of the accused.

Why treachery was not appreciated

Although the acquittal rendered discussion of the crime's elements moot, the Court addressed the qualifying circumstance of treachery. The eyewitness did not see how the attack began. He only saw the victim being chased by two armed men and could not describe the inception of the aggression.

For treachery to qualify a killing to murder, it must be present and witnessed from the very start of the attack. Where no particulars are known as to how the killing began, treachery cannot be presumed. This ruling reinforces that qualifying circumstances must be proved with the same rigor as the crime itself.

Practical takeaways

• Identity must be proved beyond reasonable doubt. Even if a crime is clearly established, conviction is impossible without clear proof of who committed it.
• Inconsistencies on identity matter. A witness who names different perpetrators at different times undermines the prosecution's case, especially when the conviction rests on that witness alone.
• Affidavits are not automatically weaker. While court testimony generally prevails over an affidavit, that rule yields when the discrepancy goes to the core issue of who committed the crime.
• Treachery must be witnessed from the start. The qualifying circumstance cannot be presumed if no one saw how the attack began.
• Doubt favors the accused. Any doubt as to the identity of the perpetrators must be resolved in favor of the accused, consistent with the constitutional presumption of innocence.
