G.R. No. L-39383 March 14, 1988
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. CATALINO GUTIERREZ, JR. y BUQUID, accused-appellant.

FACTS

Accused-appellant Catalino Gutierrez, Jr. was convicted of murder for the fatal stabbing of Florentino Mantuano inside a Batangas Telecommunications office. The prosecution evidence established that Gutierrez, armed with a balisong, challenged Mantuano to a fight from outside the office. The victim’s son, Benjamin, intervened and momentarily pacified Gutierrez. However, Gutierrez subsequently entered the office and stabbed Mantuano in the back while the latter was walking away. Mantuano died shortly thereafter from the wound. The prosecution presented eyewitness testimony from Benjamin, the victim’s ante-mortem statement to his wife and a police investigator, and corroborating medico-legal findings. The defense claimed self-defense, alleging that Mantuano had first attacked him with a piece of wood inside the office.

ISSUE

The core issue is whether the trial court correctly rejected the claim of self-defense and found the accused guilty of murder qualified by treachery.

RULING

The Supreme Court affirmed the conviction for murder. The legal logic proceeds from the settled doctrine that one who invokes self-defense admits the killing and assumes the burden of proving its justifying circumstances by clear and convincing evidence. The Court found the appellant’s claim of self-defense utterly unconvincing and inconsistent with the physical evidence. The nature, location, and direction of the fatal stab wound—inflicted on the victim’s back, penetrating the lung—contradicted the scenario of a frontal assault by the victim. This wound was more consistent with a sudden attack from behind, supporting the prosecution’s narrative. Furthermore, the Court upheld the finding of treachery (alevosia). The attack was executed in a manner that ensured the victim, who was unarmed and walking away, had no opportunity to defend himself. The suddenness of the assault from behind directly and specifically ensured the execution of the crime without risk to the assailant. The Court also found the victim’s ante-mortem statements, corroborated by other evidence, to be credible and admissible as dying declarations. The defense’s claim that the incident occurred in a crowded office was deemed irrelevant, as the evidence convincingly showed the attack did happen as described. The appealed decision was affirmed with the modification of increasing the civil indemnity from P12,000 to P30,000.
