G.R. No. L-30463 October 30, 1972
THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. MANUEL CUSTODIO Y CARILLO, Alias “Sayke”, accused-appellant.

FACTS

Accused Manuel Custodio, along with Angelito Paglicawan and Rosauro Roque, was charged with Murder for the killing of Jesus Dequiña. The prosecution alleged that on January 29, 1969, in Manila, the accused conspired to attack the victim. Paglicawan held Dequiña by the neck while Roque stabbed him multiple times, causing fatal wounds. Both Paglicawan and Roque later pleaded guilty and were sentenced to reclusion perpetua. Custodio, however, pleaded not guilty, was convicted as a co-conspirator, and sentenced to death, leading to this automatic review.
The prosecution’s case against Custodio hinged on establishing his participation in a conspiracy. Witness Angelina Malonso testified that a month before the killing, she overheard a conversation where Roque stated an intent to kill her husband, Dequiña, and Custodio remarked, “Why, does he have nine lives?” Eyewitness Ricardo Sebastian testified that during the attack, Custodio stood guard approximately three arms’ length away from the victim, holding a bolo. The prosecution argued this act of “standing guard” constituted indispensable cooperation in the crime.

ISSUE

Whether the evidence presented by the prosecution proves beyond reasonable doubt that accused-appellant Manuel Custodio conspired with or cooperated in the murder of Jesus Dequiña.

RULING

The Supreme Court ACQUITTED Manuel Custodio. The Court held that the evidence failed to establish his guilt as a co-conspirator or accomplice beyond a reasonable doubt. The testimony regarding the alleged prior conversation was deemed insufficient to prove a conspiracy, as the meeting between the accused and the victim on the night of the crime was found to be accidental, not a planned execution of a prior agreement. Mere knowledge of a criminal intent, without proof of an agreement to commit the crime, does not constitute conspiracy.
Crucially, the act of “standing guard” was not considered conclusive proof of cooperation. The Court ruled that for an individual to be liable as an accomplice, there must be a showing that he cooperated in the commission of the offense with the intention of supplying material or moral aid in an efficacious way. Custodio’s mere presence at the scene, and the fact he was holding a bolo, without any overt act demonstrating a clear intent to aid in the killing—such as threatening bystanders or preventing the victim’s escape—was deemed insufficient to constitute such cooperation. His presence could be attributed to mere companionship. The prosecution’s evidence did not meet the required standard of moral certainty to overcome the constitutional presumption of innocence. Therefore, the conviction was reversed.
