Case Summary (G.R. No. 117983)

Court Convictions and Sentences

The Court of First Instance of Samar convicted both brothers of murder. Gerardo Diaz received a sentence of reclusion perpetua, while Francisco Diaz was sentenced to an indeterminate penalty of ten years and one day of prision mayor to seventeen years of reclusion temporal. Both were ordered to pay P6,000 in indemnity to the heirs of the victim and to cover the costs of the proceedings.

Evidence and Eyewitness Testimony

The prosecution relied on eyewitness accounts rather than circumstantial evidence. Francisco Diaz admitted to killing Tadia but pleaded self-defense. Gerardo Diaz claimed an alibi. The court's primary considerations were the credibility of Francisco's self-defense claim and Gerardo's alibi, alongside allegations of conspiracy and the application of treachery and premeditation in qualifying the act as murder.

Circumstances of the Crime

On the afternoon of September 4, 1963, Francisco Diaz assaulted Remegia Carasos, prompting her and her cousin Anita Pacaira to seek help from their grandfather, Quintin Tadia. The following morning, while Tadia and the girls were on their way to file a complaint against Francisco, both appellants ambushed Tadia. Gerardo shot Tadia in the neck, leading Francisco to stab Tadia multiple times while he lay incapacitated.

Medical Findings

An autopsy conducted by Dr. Tecla Tagle Valley revealed Tadia sustained multiple stab wounds and gunshot injuries that directly led to his death. This medical evidence corroborated the testimonies provided against the Diaz brothers and confirmed the fatality of the injuries.

Defense and Rebuttal

Francisco Diaz's defense of self-defense was found to be implausible given the circumstances and the timeline of events, particularly the injuries he described as having been inflicted by Tadia, which were actually sustained during the prior day's confrontation with Anita. Gerardo's alibi was equally weak, marked by inconsistencies in testimonies from him and his family regarding his whereabouts on the day of the murder.

Eyewitness Credibility

The trial court found Remegia and Anita to be credible witnesses, affirming their positive identification of Gerardo as the shooter. Their demeanor during testimonies added to their reliability, and the clear details they provided effectively discredited Gerardo's alibi.

Conspiracy and Intent

The evidence presented indicated a conspiracy between the brothers to kill Tadia to prevent him from filing a complaint for the earlier assault on Remegia. The brothers coordinated their actions, with Gerardo providing the means (the gun) and directing Francisco to continue the assault after Tadia was incapacitated.

Qualifying Circumstances of the Crime

The killings were characterized by treachery due to the unexpected nature of the ambush, which left Tadia unable to defend himself. The attack was carried out with deliberate surprise, and the nature of their assault indicated a premeditated agreement to execute the crime.

Sentencing and Legal Considerations

The court recalibrated the sentences, establishing that Francisco Diaz's actions warra
