G.R. No. 104666 February 12, 1997
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. BIENVENIDO OMBROG y MAGDARAOG, respondent-appellant.

FACTS

The prosecution’s case, as established through eyewitness Ronald Bordallo, a 13-year-old student, was that on the evening of August 17, 1990, he, the victim Arnel Quilang, and others including the accused-appellant Bienvenido Ombrog, were having a drinking session in Tondo, Manila. During the session, Ombrog briefly left and returned, then suddenly approached Quilang from behind and stabbed him with a household knife. The victim was brought to the hospital but later died from his wounds. Bordallo positively identified Ombrog in court as the assailant.
The defense interposed denial and alibi. Ombrog claimed he was in Mindoro gathering calamansi from August 14 to 20, 1990, and did not know the victim. Defense witness Jonathan Adriano corroborated the drinking session but testified that the assailant was a certain “Pedring” Cabacang, not Ombrog. The accused asserted he was a resident of Caloocan, not Tondo, and denied any motive for Bordallo to falsely accuse him.

ISSUE

The core issue is whether the defenses of denial and alibi can prevail over the positive identification of the accused by an eyewitness, thereby overturning the trial court’s conviction for Murder.

RULING

The Supreme Court affirmed the conviction, ruling that the defenses of denial and alibi must fail against the positive and credible testimony of the prosecution eyewitness. The Court emphasized that the assessment of witness credibility is best left to the trial court, which had the unique opportunity to observe the witnesses’ demeanor and manner of testifying. The trial judge found the testimony of young witness Ronald Bordallo to be clear, straightforward, and credible, noting his detailed account of the incident and his positive in-court identification of Ombrog.
The legal logic is anchored on the principle that alibi and denial are inherently weak defenses, easily fabricated and difficult to prove. For alibi to succeed, the accused must demonstrate not only that he was elsewhere when the crime occurred but that it was physically impossible for him to have been at the crime scene. Ombrog failed to meet this stringent requirement, as Mindoro was not so distant as to preclude his presence in Manila on the date in question. Conversely, positive identification by a credible witness, when categorical and consistent, is sufficient to support a conviction. The Court found no ill motive for Bordallo to falsely testify, and his testimony was corroborated by the medico-legal findings. The qualifying circumstance of treachery was correctly appreciated, as the attack was sudden and from behind, ensuring the victim had no opportunity to defend himself. However, the Court agreed with the trial court that the other alleged circumstances of evident premeditation and nighttime were not proven with the required certainty. Thus, the conviction for Murder qualified by treachery and the penalty of reclusion perpetua were upheld.
