G.R. No. 134572 ; April 18, 2002
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. DIONISIO UMAYAM y CASTRO, accused-appellant.

FACTS

The accused-appellant, Dionisio Umayam, was charged with the murder of his common-law wife, Emma Mendoza. The prosecution presented witness Rodolfo Velasquez, in whose compound the couple lived. Velasquez testified to their tumultuous relationship, frequent quarrels, and incidents where the victim sought help due to beatings. On the evening of February 7, 1992, Velasquez saw the accused, the victim, and another person enter their shanty. A loud radio played until Velasquez left around 9-10 PM. A foul odor later emanated from the shanty, leading to the discovery of Mendoza’s decomposing body on February 10. The autopsy revealed fatal stab wounds and contusions.
The defense presented an alibi. Accused-appellant claimed he was at his sister’s house in Parañaque from February 4 to 11, 1992, awaiting the victim who had left to visit her children. His sister and a neighbor corroborated his presence, stating he was doing carpentry work and did not leave. The trial court convicted him of murder qualified by treachery and sentenced him to reclusion perpetua.

ISSUE

Whether the guilt of the accused-appellant for the killing of Emma Mendoza was proven beyond reasonable doubt.

RULING

The Supreme Court affirmed the conviction but modified the crime from Murder to Homicide. The Court found the prosecution evidence sufficient to establish guilt beyond reasonable doubt. The defense of alibi was correctly rejected by the trial court as it was not physically impossible for the accused to have been at the crime scene, given the proximity of Parañaque to Las Piñas. The testimonies of the defense witnesses were deemed unreliable, with the neighbor’s testimony showing inconsistencies and being impeached by evidence of her failure to come forward earlier.
However, the Court ruled that the qualifying circumstances of treachery and evident premeditation were not proven. The Information alleged these, but the prosecution failed to present evidence detailing how the attack was commenced or executed. The mere fact of a stab wound does not automatically establish treachery; the manner of assault must be shown to ensure the victim had no opportunity for defense. With no qualifying circumstance proven, the crime is Homicide under Article 249 of the Revised Penal Code. The penalty was modified to an indeterminate sentence of 8 years and 1 day of prision mayor as minimum to 14 years, 8 months and 1 day of reclusion temporal as maximum. Civil indemnity of P50,000 and moral damages of P50,000 were awarded to the victim’s heirs.
