G.R. No. 147786 ; January 20, 2004
PEOPLE OF THE PHILIPPINES, Appellee, vs. ERIC GUILLERMO y GARCIA, Appellant.

FACTS

Appellant Eric Guillermo was charged with the murder of his employer, Victor Francisco Keyser. The prosecution established that on March 22, 1998, at the Keyser Plastic Manufacturing Corp. in Antipolo City, Guillermo killed Keyser by bashing his head with a piece of wood and subsequently dismembering the body with a saw. Security guard Romualdo Campos testified that he heard loud noises from the premises and later saw Guillermo, who calmly confessed to the killing and solicited Campos’s help to dispose of the body. Police officers responded, secured the scene, and recovered the dismembered corpse and the weapons. Guillermo voluntarily surrendered and made extrajudicial statements admitting the act and citing maltreatment as his motive.
At trial, Guillermo claimed self-defense, alleging that Keyser attempted to sexually abuse him, leading to a struggle during which he struck Keyser in defense. He also argued that his extrajudicial confession was inadmissible as it was taken without the assistance of counsel and prior Miranda warnings. The Regional Trial Court found him guilty of murder qualified by treachery and sentenced him to death, prompting automatic review.

ISSUE

The core issue is whether the trial court correctly convicted appellant of murder and imposed the death penalty.

RULING

The Supreme Court affirmed the conviction but modified the penalty. The Court rejected the claim of self-defense as appellant failed to prove unlawful aggression by the victim. The nature and number of the victim’s head wounds, coupled with the subsequent dismemberment, were inconsistent with a sudden, defensive reaction and instead indicated a determined assault. Treachery was correctly appreciated because the attack was sudden and from behind, ensuring the victim had no opportunity to defend himself.
Regarding the extrajudicial statements, the Court ruled that while the formal confession taken at the police station without counsel was inadmissible, appellant’s spontaneous oral confession to the security guard immediately after the crime was admissible as part of the res gestae. This statement, along with the physical evidence and his voluntary surrender to the police, constituted proof beyond reasonable doubt. However, the Court reduced the penalty from death to reclusion perpetua because the qualifying circumstance of treachery was not alleged with particularity in the Information. The Information stated the killing was committed “by means of treachery and with evident premeditation” but did not specify the constitutive acts, which is required for imposing the death penalty. The award of damages was also modified in accordance with prevailing jurisprudence.
