When One Eyewitness Is Enough: Conviction for Homicide Despite Alibi and Denial

The Supreme Court has long held that a single eyewitness's credible and positive testimony can be enough to convict a person of a serious crime. In People v. Visperas Jr. (G.R. No. 147315, January 13, 2003), the Court applied this rule to uphold a conviction for homicide, even as it corrected the trial court's error in convicting the accused of murder. The case is a useful guide on how courts weigh eyewitness accounts against the defenses of denial and alibi, and on the strict requirement to prove qualifying circumstances.

The Facts of the Case

On the night of June 23, 1999, Elmadona de Guzman was in the kitchen of her home in Mangaldan, Pangasinan, waiting for her husband Tito to arrive. She heard gunshots and, peeping through a window, saw her husband being shot. She identified Tomas Visperas Jr. as the man who ran toward her falling husband and shot him at close range on the forehead. The victim died from a gunshot wound to the head.

Visperas was charged with murder, along with two other men who were later acquitted. The prosecution's case rested chiefly on the widow's eyewitness testimony, corroborated by the autopsy report. Visperas denied involvement and presented an alibi, claiming he was drinking with his uncle in a nearby barangay at the time of the killing.

The Issue Before the Court

The central question was whether the testimony of a single eyewitness was sufficient to convict Visperas of murder. The Court also examined whether the killing was properly qualified as murder and whether the trial court had erred in relying on hearsay evidence.

The Ruling: One Credible Witness Can Convict

The Supreme Court affirmed the conviction but modified it from murder to homicide. The Court ruled that the widow's testimony was "staunch, positive and credible." Despite grueling cross-examination, she testified repeatedly and unwaveringly that Visperas shot her husband at close range. Her account was corroborated by the post-mortem report showing a fatal gunshot wound to the forehead.

The Court reiterated the well-settled rule: the testimony of a single eyewitness, if credible and positive, is sufficient to support a conviction, even in a charge of murder. Trial courts are in the best position to assess witness credibility, and their findings will not be disturbed on appeal absent arbitrariness or oversight of material facts.

Why Denial and Alibi Failed

Visperas's defenses could not overcome the eyewitness account. Denial, the Court noted, must be buttressed by strong evidence of non-culpability. His alibi also failed because he testified that the barangay where he claimed to be was only 14 kilometers away—hardly making it physically impossible for him to be at the crime scene. The Court described alibi as "the weakest of all defenses," easily contrived and difficult to disprove, especially when supported only by relatives.

The Hearsay Error and the Missing Qualifying Circumstance

The Court did find one error in the trial court's reasoning: it improperly considered hearsay statements from unidentified persons near the crime scene. Those persons were never presented in court, so their statements had no probative value. However, this error did not undermine the conviction because the widow's testimony and physical evidence independently established guilt.

More importantly, the Court found that the prosecution failed to prove any qualifying circumstance—such as treachery or evident premeditation—that would elevate the killing to murder. A qualifying circumstance must be proven with the same certainty and clearness as the crime itself. Since none was proven, Visperas was guilty only of homicide, punishable by reclusion temporal under Article 249 of the Revised Penal Code.

Damages Awarded to the Heirs

The Court sustained the awards of P50,000 as civil indemnity and P50,000 as moral damages. It deleted the awards for actual and temperate damages for lack of evidence, but awarded P1,800,000 for loss of earning capacity, computed using the victim's monthly income of P10,000 and a life expectancy of 30 years.

Practical Takeaways

• A single eyewitness can be enough. Courts do not require multiple witnesses to convict. What matters is that the testimony is credible, positive, and unwavering.
• Denial and alibi are weak defenses. To succeed, an alibi must show it was physically impossible for the accused to be at the crime scene. Denial must be supported by strong evidence of non-culpability.
• Qualifying circumstances must be proven. A killing is only murder if a qualifying circumstance like treachery or evident premeditation is established with the same certainty as the crime itself. Otherwise, the crime is homicide.
• Hearsay cannot support a conviction. Statements from persons not presented in court have no probative value, even if no objection was raised during trial.
• Damages must be proven. Actual damages require receipts or other evidence. Loss of earning capacity, however, can be computed from testimony of the victim's income.
