G.R. No. L-18763-64 May 23, 1964
THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. EFREN MARTIN, ET AL., defendants-appellants.

FACTS

Efren Martin, Agustin Martin, Elino Martin, and Eriberto Martin were charged with the murder of Edmundo Nepomuceno. The prosecution evidence established that on the evening of December 17, 1960, after a prior provocation by Emilio Martin (a brother not among the appellants), the victim Edmundo left his house. Efren Martin immediately accosted him, held him by the collar, and stabbed him with a kitchen knife. This initial assault was followed by a concerted attack. Benny Yumang hit Edmundo with a piece of wood, Pete Nunag struck him at the back of the head, and then the other Martin brothers—Elino, Eriberto, Emilio, and Agustin—emerged and successively assaulted the already fallen victim. Pablo Nunag held Edmundo up by the shoulder while the Martins stabbed him. The assailants continued kicking him even as he crawled toward his room. The victim sustained multiple fatal wounds, including four stab wounds and a hacking wound, and died from profuse hemorrhage and shock.

ISSUE

The core issue is whether the guilt of the appellants for the crime of murder was proven beyond reasonable doubt, considering their defenses of denial, alibi, and Eriberto Martin’s claim of self-defense.

RULING

The Supreme Court affirmed the conviction. The Court found the collective testimony of prosecution witnesses, including the victim’s sister and common-law wife, to be credible and consistent, detailing a coordinated attack by the group. The nature, number, and location of the victim’s wounds—multiple stab wounds and a hacking wound—completely belied Eriberto Martin’s claim of sole self-defense involving only two knife thrusts. The medical evidence showed injuries inflicted by at least two different weapons, which could not have been caused by a single person acting in self-defense, especially given that Eriberto claimed to have been unarmed initially and emerged without a single injury. The Court also rejected the alibis of the other appellants as weak and unsubstantiated, noting they were positively identified at the scene. The trial court’s findings on the existence of conspiracy were upheld based on the appellants’ collective and successive actions demonstrating a common purpose to kill. The mitigating circumstance of voluntary surrender was correctly appreciated only for Eriberto Martin, who had admitted his participation. The penalties imposed by the trial court were thus affirmed.
