G.R. No. L-65175 April 15, 1988
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. MARCELINO GUARNES y LANZUELA, accused-appellant.

FACTS

The accused-appellant, Marcelino Guarnes, was charged with the special complex crime of rape with homicide. The information alleged that on September 2, 1975, in Bula, Camarines Sur, he raped Marcelina Apundar and, by reason and on the occasion thereof, strangled her and placed earth and leaves on her nose and mouth, causing her death by asphyxiation. During the preliminary investigation and upon arraignment, Guarnes, assisted by counsel-de-oficio, pleaded guilty. The trial court, based on his plea and the evidence, rendered a judgment of conviction and imposed the death penalty.
The prosecution’s evidence, presented after the guilty plea to determine the precise degree of culpability, was largely circumstantial. It established that Guarnes was working near the crime scene on the day of the incident. Witnesses noticed fresh scratches on his neck shortly thereafter. Most critically, footprints with an unusual inward-bent toe shape, found near the victim’s body, were matched to Guarnes’s distinct feet, a characteristic remembered by a police officer from a prior investigation. Guarnes later recanted his plea, claiming he was forced by others to act as a lookout and was threatened into admitting guilt.

ISSUE

Whether the conviction of the accused-appellant for the crime of rape with homicide, based primarily on circumstantial evidence and a withdrawn plea of guilty, is valid and supported by proof beyond reasonable doubt.

RULING

Yes, the conviction is valid. The Supreme Court affirmed the judgment of conviction but commuted the death penalty to reclusion perpetua in accordance with the Constitution. The Court held that a plea of guilty, especially in a capital offense, does not automatically result in conviction; the prosecution must still prove the crime and the precise degree of culpability. Here, the prosecution successfully discharged this burden through circumstantial evidence.
The legal logic rests on the sufficiency of circumstantial evidence to establish guilt beyond reasonable doubt. The Court applied the established doctrine that circumstantial evidence is sufficient for conviction when: (1) there is more than one circumstance; (2) the facts from which the inferences are derived are proven; and (3) the combination of all circumstances produces a moral certainty of guilt. The proven circumstances—Guarnes’s presence at the locus criminis, the fresh scratches on his person, and the singular match between his uniquely shaped feet and the footprints at the scene—formed an unbroken chain leading to the reasonable and singular conclusion that he was the perpetrator. His defense of being coerced into a lookout role was deemed illogical and unconvincing, as he had ample opportunity to report the alleged coercion but did not. His initial consistent pleas of guilty, made with assistance of counsel and after judicial admonition, further undermined his belated denial. Thus, the totality of evidence met the standard of moral certainty required for a conviction.
