G.R. No. 85434 May 17, 1993
People of the Philippines, plaintiff-appellee, vs. Perfecto Crisostomo and Rodolfo Pantaleon, accused-appellants.

FACTS

On March 8, 1983, in Barangay San Isidro, Uson, Masbate, accused-appellants Perfecto Crisostomo and Rodolfo Pantaleon, while drinking and armed, chased Cesario Loyao, the victim’s son-in-law, towards the victim’s house. At around 6:30 p.m., Cesario Loyao saw Crisostomo stab his 68-year-old mother-in-law, Andrica Agbay, from behind with a machete while she was carrying a lighted torch. He witnessed Crisostomo holding the victim’s right arm and Pantaleon holding her left arm, armed with a bolo. The victim fell after being stabbed. Remedios Loyao, the victim’s daughter, also saw the stabbing from her window, observing Crisostomo pulling the machete from her mother’s chest, with both appellants holding the victim’s arms. A neighbor, Angeles Adolfo, heard shouts, ran to the scene, saw the victim dead, and witnessed both appellants jumping over the fence and fleeing. The police later arrested Crisostomo, who admitted the stabbing and revealed Pantaleon’s hiding place; Pantaleon also admitted participation upon arrest. The autopsy confirmed a stab wound as the cause of death. At trial, both accused pleaded not guilty and presented alibis and claims of motive by the prosecution witnesses. The Regional Trial Court found Crisostomo guilty of Murder and Pantaleon as an accomplice.

ISSUE

The main issues were: (1) the credibility of the prosecution witnesses versus the accused’s defenses of alibi and alleged motives; (2) the presence of treachery qualifying the killing to murder; and (3) whether conspiracy existed, making Pantaleon a principal and not merely an accomplice.

RULING

The Supreme Court affirmed the conviction but modified the ruling on conspiracy and the penalty. It held that the positive, straightforward testimonies of the prosecution witnesses were credible and sufficient to establish guilt beyond reasonable doubt, rejecting the weak defenses of alibi. The Court found that treachery was present because the victim, an elderly woman, was held by both appellants, rendering her defenseless, and was stabbed from behind, with the means deliberately adopted to ensure execution without risk. The Court further ruled that conspiracy existed, as the concerted acts of both appellants—holding the victim’s arms to facilitate the stabbing—demonstrated a common purpose to kill. Consequently, Pantaleon was not merely an accomplice but a co-principal. The Court sentenced both accused-appellants to reclusion perpetua and increased the civil indemnity to P50,000.00.
