G.R. No. 101556 - People vs. Estera

On 13 January 1984, in Barangay Rama, Catbalogan, Samar, a tragic incident occurred in the midst of a local fiesta celebration.
The victim, Uldarico Bulan, resided in a house adjacent to that of Margarita Avila and near the house of Francisco and Josenia Sidon, with Josenia being the daughter of the victim.
The accused-appellant, Roberto Estera alias Ruben, who was then a member of the CHDF and assigned as part of the security force for Mayor Raul Munoz, traveled with his family to Barangay Rama.
Upon arrival, he was issued a baby Armalite M16 rifle (caliber 5.56 mm, Serial No. R.P. 127200) with sixty (60) rounds of ammunition by the local Military Police Brigade.

After arriving with his family, the accused proceeded to the house of Margarita Avila, where a drinking spree ensued among him and other individuals.
At about 7 o’clock in the evening, a gunshot was heard from the direction of the Avila house. The victim, Uldarico Bulan—who lived in an adjacent house—warned those at the Avila residence, mentioning a sensitive condition at home (a recent childbirth by his daughter).
Approximately one hour later, another gunshot rang out near the Bulan household’s “banggerahan” (a bamboo structure with slats allowing an outside view).
Helen Bulan, a daughter of the victim, who was inside the house, looked out and saw the accused in an assault position with his M16 rifle. Soon after, she witnessed a volley of gunshots, during which her father, Uldarico, was fatally shot.

Uldarico Bulan, while being helped by his daughter and wife, made a clear declaration identifying the accused—“You stand for it because it was Ruben Estera who shot me.”
This statement was made immediately prior to his death, bolstering its credibility as a dying declaration or part of the res gestae.

Around 10 o’clock in the evening, the accused re-entered the Bulan house, admitted his association with the firearm by remarking, “You might say I was the one who shot him as I am the only person who had a firearm.”
He then joined the gathering at the wake before eventually leaving the scene, later providing assistance to the police the following morning.

Autopsy results on 14 January 1984 revealed nine gunshot wounds on the victim, with three being fatal, and descriptions indicating most shots were delivered from behind.
Six empty shells (four from the “banggerahan” and two outside) were collected and later matched via ballistic examination to test shells fired from the accused’s baby Armalite.
The accused returned the firearm and leftover ammunition on 16 January 1984 after testing it minimally (two rounds fired).

He had tested the rifle by firing two shots into the air to check its functionality upon reaching Barangay Rama.
Being intoxicated from drinking rhum during the trip, he had rested and inadvertently fallen asleep, only awakening at approximately 8 o’clock when gunshots were heard.
He then observed the commotion, verified the presence of people near the Bulan house, and took subsequent actions including moving his family and later assisting the authorities.

A defense witness, Lucresio Lomuardo, provided testimony describing a man in a military-type raincoat firing shots near the Reading Center, but later admitted that the dark conditions rendered his identification inconclusive.
The defense submitted a copy of a police blotter entry reporting the incident by Helen Bulan, which recorded that the shots were fired by “unidentified men” – an exhibit whose probative value was later challenged by the Court.

Whether the various pieces of evidence – particularly the eyewitness testimonies, the victim’s dying declaration, and the forensic ballistic tests – sufficiently established that Roberto Estera alias Ruben was present at the scene and committed the murder beyond reasonable doubt.
Whether the accused-appellant’s alibi, which relied on claims of intoxication and accidental timing, was credible enough to rebut the affirmative evidence linking him to the crime.
The appropriate interpretation and admissibility of the dying declaration as decisive evidence in convicting the accused.
The propriety of modifying the penalty from an indeterminate sentence to reclusion perpetua in light of the presence of both aggravating (treachery, possession of a heavy firearm) and mitigating (intoxication) circumstances.

The reliability and corroboration of the police reports and the witness accounts against the inconsistent defense narrative.
The significance of the ballistic evidence in linking the accused’s firearm to the shell casings recovered from the scene.
Whether the circumstances surrounding the gathering of evidence, including the chain-of-custody issues, could affect the integrity of the forensic findings.
