G.R. No. 229349 - People vs. Antonio y Pableo

Greg Antonio y Pableo @ Tokmol (Antonio) was charged in two separate Informations before the Regional Trial Court (RTC)—one for frustrated murder and another for murder—arising from stabbing incidents on August 15, 2006, in Manila.
In Criminal Case No. 06-246909 (frustrated murder), Antonio was accused of stabbing Arsenio Cahilig y Malinana with intent to kill, but the victim survived due to timely medical intervention.
In Criminal Case No. 06-246310 (murder), Antonio was accused of stabbing Arthuro Villalobos y Bijasa multiple times with intent to kill, resulting in Villalobos’ death.
The two cases were consolidated; Antonio pleaded not guilty to both charges.

Witnesses for the prosecution included David Fresado, Ligaya Villalobos (mother of the deceased), Dr. Romeo T. Salen (post-mortem examiner), and Police Inspector Ismael Dela Cruz.
Testimonies revealed that on August 15, 2006, early morning, Villalobos was drinking with companions when a woman named Lorna, Antonio's sister, joined trying to sell a cellphone, sparking an altercation between Lorna and Villalobos.
After the fight was broken up, Villalobos followed Lorna to Delpan Bridge; Fresado and others followed as well.
At the bridge, Antonio appeared suddenly, placed his arm around Villalobos, and stabbed him repeatedly with a foot-long knife. Lorna and her husband joined in attacking Villalobos.
Villalobos managed to break free but sustained fatal wounds and later died. Cahilig was also stabbed but survived.
Post-mortem examination indicated five stab wounds on Villalobos, three fatal. Ligaya testified about expenses for Villalobos’ burial, but receipts were not presented.

Antonio testified on his own behalf, claiming self-defense and defense of his sister.
According to Antonio, Villalobos and his companions assaulted Lorna unprovoked and attempted to stab him.
Antonio wrestled the knife from Villalobos and stabbed him several times in defense of himself and his sister.
He admitted killing Villalobos but denied stabbing Cahilig.

The RTC acquitted Antonio of frustrated murder due to lack of evidence on who stabbed Cahilig.
The RTC convicted Antonio of murder, emphasizing that Antonio’s claims of self-defense were inconsistent and uncorroborated.
The court found aggravating circumstances of treachery and evident premeditation.
The RTC sentenced Antonio to reclusion perpetua and ordered damages to Villalobos’ heirs.

The Court of Appeals affirmed the murder conviction but modified the ruling by upholding treachery only, dismissing evident premeditation due to lack of evidence.
The award for moral damages was increased.
The Court of Appeals found Fresado’s eyewitness account credible over Antonio’s inconsistent defense testimony.

Antonio appealed to the Supreme Court, invoking self-defense and defense of a relative, maintaining he acted legally to protect his sister from unprovoked assault.
The People emphasized that Antonio failed to prove the requisites of justifying circumstances, and treachery was justly applied.

Whether or not the accused-appellant Greg Antonio y Pableo @ Tokmol proved the existence of the justifying circumstances of self-defense and defense of a relative.

Whether or not the killing of Arthuro Villalobos was attended by the aggravating circumstance of treachery and/or evident premeditation.
