G.R. Nos. L-57809-10 August 28, 1984
The People of the Philippines, plaintiff-appellee, vs. Carlito Quiban, defendant-appellant.

FACTS

Appellant Carlito Quiban was convicted of murder for killing Francisco Tolibas and frustrated murder for wounding Filemon Ramada. The prosecution evidence established that on December 31, 1979, after a drinking session where Quiban paid a substantial bill, an altercation ensued aboard their fishing boat. Quiban, allegedly feeling aggrieved over the expense, initiated an attack. He first rushed at Romeo Velarde with a knife, causing Velarde to jump overboard. Quiban then pursued and stabbed Tolibas, who stumbled. After leaving to look for others, Quiban returned to where the already helpless Tolibas lay and stabbed him several more times. He also chased and stabbed Ramada, who had jumped into the water to escape.
The defense presented a different version, claiming self-defense. Quiban testified that upon boarding the boat, he was suddenly attacked by Velarde with an ax and by Tolibas with a knife and a spear. He claimed he only wrested a weapon and stabbed Tolibas to defend himself before jumping overboard, where he was pursued by Ramada.

ISSUE

The primary issues were: (1) whether the trial court erred in finding Quiban was the aggressor; (2) whether treachery attended the killing of Tolibas; and (3) whether treachery was present in the wounding of Ramada.

RULING

The Supreme Court affirmed the murder conviction for the killing of Tolibas but modified the conviction for the wounding of Ramada to frustrated homicide. The Court upheld the trial court’s finding that Quiban was the aggressor. The logical inference from human behavior, as noted by the trial court, was that Quiban, feeling deceived and aggrieved over paying the drinks bill, was the one who initiated the violence. The nature and number of wounds inflicted on the victims were inconsistent with a claim of self-defense against multiple armed assailants.
Regarding treachery in the killing of Tolibas, the Court ruled it was present. While the initial attack did not constitute treachery as Tolibas had a chance to flee, the subsequent attack qualified. The evidence showed Quiban left the scene, returned, and stabbed the already helpless and defenseless Tolibas multiple times. This break in the continuity of the aggression, followed by an attack on a defenseless victim, constituted treachery under established jurisprudence.
However, the Court found no treachery in the attack on Ramada. Ramada was already alerted to the trouble, having been awakened and warned of the ongoing violence, and had even heard Quiban’s threats. This forewarning placed Ramada on guard, thereby negating the element of surprise or helplessness essential for treachery. Consequently, the crime committed against him was properly frustrated homicide, not frustrated murder. The penalties and indemnities were modified accordingly.
