G.R. No. L-38163. April 27, 1982.
THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. ESTANISLAO SUMADIC, accused-appellant.

FACTS

The prosecution’s evidence established that on the evening of September 1, 1972, Cirila Sampil and her husband, Luis, were walking home in Barangay Pungsod, Sta. Barbara, Iloilo, after alighting from a tricycle. Cirila testified that she saw the appellant, Estanislao Sumadic, run towards her husband from behind and stab him without warning while Luis was urinating. After the initial attack, the victim was assisted towards a tricycle. As Luis was being loaded into the vehicle, the appellant returned and stabbed the already fallen and defenseless man several more times. The victim died from the wounds. The prosecution presented eyewitnesses Cirila Sampil and Nelly Sucaldito to corroborate these events.
The appellant interposed the defense of denial and frame-up. He claimed that three other armed men waylaid and stabbed Luis Sampil. He testified that he ran to help the victim and even assisted in loading him into the tricycle. He alleged that the same three men later accosted him, threatened him and his family, and detained him overnight to prevent him from reporting the incident, thus explaining his absence and subsequent implication.

ISSUE

Whether the trial court erred in convicting the appellant of murder qualified by treachery.

RULING

The Supreme Court affirmed the conviction. The legal logic rests on the conclusive establishment of treachery (alevosia) and the superior credibility of the prosecution’s evidence. Treachery exists when the offender employs means, methods, or forms in the execution of the crime which tend directly and specially to ensure its execution without risk to himself arising from the defense which the offended party might make. The Court found that the first attack was sudden and unexpected, executed while the victim was urinating and thus unable to defend himself. The second series of stabs occurred when the victim was already collapsed and utterly defenseless. These circumstances clearly constituted treachery, qualifying the killing as murder.
The Court upheld the trial court’s assessment of the witnesses’ credibility, noting the positive, straightforward, and unwavering testimonies of the prosecution eyewitnesses, who were found to have no improper motive to falsely testify against the appellant. In contrast, the appellant’s defense of denial was weak and inherently improbable. Furthermore, the prosecution evidence revealed a motive stemming from a prior altercation where the appellant was admonished by the victim during a barrio dance and uttered threats. The findings of fact of the trial court are generally binding on appeal, especially on the matter of witness credibility. Consequently, the Supreme Court found no reversible error and affirmed the judgment convicting Estanislao Sumadic of murder and sentencing him to reclusion perpetua.
