G.R. No. 31254 , September 25, 1929
PEOPLE OF THE PHILIPPINE ISLANDS vs. TRANQUILINO CABALLERO, ET AL.

FACTS

The defendants-appellants (Tranquilino Caballero, Domingo Antepuesto, Juan Antecristo, Lope Jorello, and Miguel Antecristo) were convicted of homicide for the death of Carlos Purgatorio. The incident occurred on the day of a wedding feast. The defendants went together to invite Carlos and his father, Pedro Purgatorio, to the feast. Carlos refused and made sarcastic remarks, accusing the defendants of breaking their promise to provide provisions and fetch them earlier. Offended, the defendants attacked Carlos almost simultaneously: Tranquilino Caballero struck him with a cane on the forehead, Domingo Antepuesto hit him with a club on the arm, Juan Antecristo beat him with a stick, and Lope Jorello struck him with a coconut palm. Miguel Antecristo then picked up a stone and struck Carlos in the occipital region, causing him to fall unconscious, leading to his death from cerebral hemorrhage. The prosecution witnesses (Pedro Purgatorio, Matilde Purgatorio, and Isidro Apostol) testified to these events. The defense contended that the witnesses were not credible and suggested that Carlos was killed by his own father, but the trial court rejected this.

ISSUE

Whether the trial court erred in convicting the defendants of homicide based on the credibility of the prosecution witnesses and in finding them liable as principals or accomplices despite the absence of a prior conspiracy.

RULING

The Supreme Court affirmed the conviction but modified the classification of liability. The Court held:
1. Credibility of Witnesses: The trial court did not err in believing the prosecution witnesses. Pedro Purgatorio’s initial inconsistent statement to the municipal president was satisfactorily explained due to threats from the defendants, and the testimonies of Matilde Purgatorio and Isidro Apostol were consistent and credible.
2. Liability for Homicide: Although there was no prior conspiracy, the defendants acted with a common purpose to punish Carlos for his insulting refusal. Their simultaneous attack constituted cooperation by simultaneous acts under Article 15 of the Penal Code. Miguel Antecristo, who delivered the fatal blow with a stone, was the principal by direct participation. The others (Tranquilino Caballero, Domingo Antepuesto, Juan Antecristo, and Lope Jorello), who struck Carlos with sticks and clubs, were accomplices because their acts, though not directly causing death, weakened Carlos and facilitated the fatal attack.
3. Aggravating Circumstance: The aggravating circumstance of abuse of superior strength was correctly applied due to the number of attackers against one unarmed victim.
The sentence of the trial court was upheld, with the modification that only Miguel Antecristo was a principal, and the others were accomplices in the crime of homicide.
