G.R. No. 106096 November 22, 1994
People of the Philippines, plaintiff-appellee, vs. Romualdo Sunga, Oscar Sunga and Dionisio Ramos, accused, Dionisio Ramos, accused-appellant.

FACTS

The case involves the killing of Vice-Mayor Ricardo Francisco. The prosecution’s eyewitness, Marcelino Espiritu, testified that on the evening of January 17, 1982, he saw accused Romualdo Sunga and appellant Dionisio Ramos outside a house. After a heated argument later ensued between Sunga and the victim, Espiritu saw Ramos holding a carbine. He then heard gunfire and saw Francisco sprawled on the ground. The victim died from three gunshot wounds on his back. The trial court convicted appellant of homicide but acquitted his co-accused, finding the evidence insufficient to prove the qualifying circumstances of murder. On appeal, the Court of Appeals found appellant guilty of murder, prompting the certification of the case to the Supreme Court.

ISSUE

The core issues are: (1) whether the circumstantial evidence is sufficient to prove appellant’s guilt beyond reasonable doubt, and (2) whether treachery attended the killing to qualify it as murder.

RULING

The Supreme Court affirmed the Court of Appeals’ decision, convicting appellant of murder. On the first issue, the Court held the circumstantial evidence sufficient for conviction. The established circumstances—appellant’s presence at the scene armed with a carbine, his retort to Espiritu, the victim’s immediate shooting after a heated argument, the fatal gunshot wounds on the victim’s back, and appellant’s flight—formed an unbroken chain leading to the reasonable conclusion that appellant was the perpetrator. This combination complies with the rules on circumstantial evidence as it produces a conviction beyond reasonable doubt.
Regarding treachery, the Court found it present, qualifying the crime as murder. The medical evidence showed the victim was shot three times in the back, indicating he was attacked from behind. Considering the victim was unarmed and the attack was sudden, executed in a manner that ensured he could not offer any defense, the element of treachery was established. The Court emphasized that treachery does not automatically arise from a rear attack, but in this case, the manner of execution—a sudden assault on an unarmed victim—clearly shows the assailants employed means to ensure the killing without risk to themselves.
