G.R. No. L-59097 September 20, 1988
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. ARSENIO TOLENTINO Y DORIA, accused-appellant.

FACTS

Arsenio Tolentino was charged with Robbery with Homicide for the killing of Police Officer Agustin Panares on April 20, 1979, in Manila. The prosecution evidence established that while Pat. Panares was conversing with a store owner, Lourdes Santos, a commotion occurred at a nearby store owned by Dionisia Datig. Datig sought Panares’s assistance. Three men, including Tolentino, then approached Panares. One held the victim from behind, a second stabbed him, and Tolentino grabbed the officer’s service firearm and shot him multiple times. The assailants fled, taking the gun.
The victim suffered fifteen wounds from stabbing and gunshots; the fatal injuries were the gunshot wounds. Tolentino later fled to Camarines Sur, where he was arrested. He verbally admitted participation and led police to recover the victim’s firearm from an associate. At trial, Tolentino denied the charge, claiming he was forced by his companions to shoot. The trial court convicted him and initially imposed the death penalty, which was later commuted to reclusion perpetua under the 1987 Constitution, leading to this appeal.

ISSUE

The core issue is whether the prosecution proved the guilt of the accused-appellant for the crime of Robbery with Homicide beyond reasonable doubt.

RULING

The Supreme Court affirmed the conviction. The legal logic centered on the establishment of conspiracy and the credibility of eyewitness testimony. Conspiracy need not be proved by direct agreement but can be inferred from the concerted actions of the assailants towards a common purpose. Here, the simultaneous and coordinated attack—where one held the victim, another stabbed him, and Tolentino seized the gun and fired the fatal shots—demonstrated a unity of purpose to kill and rob. The act of one is deemed the act of all.
The Court rejected Tolentino’s defense of being forced. His claim was illogical; having obtained the firearm, he was in a superior position to resist his companions if he were truly coerced. Instead, he used the weapon to shoot the victim. His post-crime conduct, including flight, recovery of the stolen gun through his information, and his verbal admission, further corroborated guilt. The positive identification by eyewitness Lourdes Santos, who knew both the victim and the assailants from the locality, was deemed credible and sufficient to sustain the conviction. The penalty was properly modified to reclusion perpetua in accordance with constitutional provisions.
