G.R. No. L-72936. June 18, 1987.
THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. ROLANDO PICARDAL y DEL MONTE and ROMEO PICARDAL y DEL MONTE, accused-appellants.

FACTS

On the evening of December 30, 1982, spouses Diosdada Francisco and Jose Santiago went to their Barangay Captain’s residence in Quezon City to settle a domestic dispute. After the matter was resolved, they stayed briefly before walking home. Along Howmart Road, near their house, they were blocked by three men, including appellants Rolando and Romeo Picardal. Without provocation, Rolando immediately placed an arm on Jose Santiago’s shoulder and stabbed him. Romeo then went behind the victim, held his hands, and forced him to face Rolando, who continued stabbing him multiple times with a foot-long double-bladed weapon. Diosdada ran back to the Barangay Captain’s house for help. Responding barangay tanods pursued and apprehended Rolando, who was still holding the knife, and later arrested Romeo at his nearby house. The victim died from severe hemorrhage due to multiple stab wounds.
The prosecution presented evidence, including the positive testimony of eyewitness Diosdada Francisco-Santiago, who immediately identified the appellants as the assailants. The trial court found that the prosecution established conspiracy between the brothers, convicting them of murder qualified by treachery and sentencing each to reclusion perpetua. The appellants appealed, arguing the prosecution witnesses were not credible and their guilt was not proven beyond reasonable doubt.

ISSUE

Whether the trial court erred in convicting the accused-appellants of murder based on the credibility of the prosecution’s evidence.

RULING

The Supreme Court affirmed the conviction. The legal logic centered on the evaluation of evidence and the defense’s failure to substantiate its claims. Firstly, appellant Rolando Picardal pleaded self-defense. By admitting the killing, the burden of proof shifted to him to establish this justifying circumstance by clear and convincing evidence, relying on the strength of his own evidence, not the weakness of the prosecution’s case. He failed to meet this burden. Secondly, the Court upheld the trial court’s findings on witness credibility. Eyewitness Diosdada Francisco-Santiago gave a positive and categorical identification of the appellants, whom she knew as they lived in the same house, separated only by a partition. The crime scene was sufficiently illuminated by a nearby electric post and house lights. Her immediate report to barangay tanods and execution of a sworn statement the same night bolstered her credibility. The defense’s argument that Romeo’s act of fleeing to his own house was illogical was rejected; the Court found it plausible given the proximity of the crime scene and noted his agitated state upon arrest, which indicated guilt rather than innocence. The Supreme Court emphasized the settled rule that the trial judge’s conclusions on fact and witness credibility are entitled to great weight and generally not disturbed on appeal, as the trial court is in the best position to assess demeanor. The prosecution evidence thus established conspiracy and treachery, proving guilt beyond reasonable doubt.
