G.R. No. L-78052 November 8, 1988
THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. ROLANDO ROA y ESLIT, accused-appellant.

FACTS

The prosecution established that on December 29, 1984, Atty. Roberto Tanjangco was fatally stabbed inside his car along the North Expressway in Guiguinto, Bulacan. Earlier that morning, the accused-appellant, Rolando Roa, a former employee of the victim, was seen boarding Tanjangco’s car with an unidentified companion. Witnesses from a nearby dump truck crew observed a struggle inside the moving vehicle. The wounded victim, Tanjangco, eventually alighted, pursued by two men who fled upon seeing the witnesses. Tanjangco, before succumbing to his wounds at the hospital, identified his attackers as “Kasama ko” (my companion).
Inside the abandoned car, investigators recovered a knife handle with a broken blade, a bloodied gray T-shirt, and an attache case containing P13,200. A subsequent search revealed a double-bladed instrument hidden in the car, which perfectly fit the recovered handle. The defense presented alibi witnesses, but the trial court found the prosecution’s evidence credible and convicted Roa of Murder.

ISSUE

The core issue is whether the prosecution proved the guilt of the accused-appellant for the crime of Murder beyond reasonable doubt.

RULING

The Supreme Court affirmed the conviction but modified the penalty. The Court found the collective evidence conclusive. The eyewitness accounts from the dump truck crew positively identified Roa as one of the men who alighted from the victim’s car and fled. The victim’s dying declaration, identifying his attacker as his companion, corroborated this. The recovery of the murder weapon, concealed within the car and matching the handle found at the scene, directly linked Roa to the crime. His defense of alibi was rightly rejected for being weak and unsubstantiated against the strong positive identification.
Regarding the qualifying circumstance of treachery, the Court ruled it was present. The attack was sudden and unexpected. The victim, who was driving, had his hands on the steering wheel and was in no position to defend himself from an assault initiated by a trusted companion seated beside him. The subsequent struggle witnessed was a desperate defensive act, not a negation of treachery. The Court also found evidence of conspiracy and motive rooted in robbery, given the substantial cash in the car that the attackers failed to take. The penalty was reduced to an indeterminate sentence of ten years and one day of prision mayor as minimum to eighteen years, eight months, and one day of reclusion temporal as maximum, applying the Indeterminate Sentence Law.
