Applicable Law and Constitutional Basis
Primary statutory sources and rules applied in the decision as presented: Revised Penal Code (Art. 48 on complex crimes), RA 7659 (death penalty statute; case reviewed under its provisions), Civil Code Art. 1878 (attorney’s special power for compromise), Rule 138 Sec. 23 Rules of Court (attorneys’ authority to bind clients), and evidentiary/legal precedents cited by the Court. Because the decision date is after 1990, the 1987 Philippine Constitution is the constitutional framework applicable to issues raised in the review (including challenges to the constitutionality of RA 7659), and the Court’s disposition reflects majority and minority positions on that statute.
Facts as Found at the Scene
On the evening of 25 August 1996, a hand grenade was thrown into the Dulay family hut, producing a loud explosion. Florentino, Norwela, and Nissan Dulay were found dead; Noemi Dulay sustained serious shrapnel wounds but survived. The explosion and resulting deaths and injuries were undisputed facts at trial; physical evidence recovered included grenade shrapnel and a grenade shifting lever from the crime scene.
Testimony of Ruben Meriales (Prosecution’s Key Witness)
Ruben testified that, after investigating disturbances near his cow, he concealed himself behind bamboo slats in his kitchen and observed Jaime Carpo and Warlito Ibao near his barn, Roche standing by a mango tree, and Oscar Ibao approach the Dulay hut, lift a sawali mat, throw something inside, and then flee toward the creek followed by Roche. Seconds later a loud explosion occurred. Ruben rushed to the Dulay hut, observed the carnage, and later gave a statement to the police naming the four accused. He explained initial reluctance to go to the police out of fear, but he later provided an affidavit and formal statement.
Police Investigation and Physical Evidence
Police responding to the explosion recovered grenade shrapnels and a grenade shifting lever at the scene. Officers also spoke with survivors and with Ruben, who identified the accused. Police visited the houses of the suspects; some houses were locked and dark at the time. The physical evidence established the occurrence of an explosion by a hand grenade; identification of perpetrators depended primarily on Ruben’s eyewitness account.
Defense Theory: Alibi and Motive to Fabricate
All accused interposed alibis asserting they were elsewhere when the blast occurred. Jaime maintained he was at home in Brgy. Libsong (about 150 meters from the Dulays) and that he checked with tanods after hearing the explosion; the Ibaos claimed they were at a family farewell party in the vicinity and denied participation. The defense also contended Ruben had motive to lie because Roche was a suspect in the murder of Ruben’s brother (Delfin Meriales), and Ruben harbored resentment that could have produced fabrication or misidentification. The accused also offered alleged post-arrest admissions and lie detector test results (NBI polygraph reports) as favorable to them.
Trial Court Findings and Sentencing
The trial court credited Ruben’s testimony in full, found the accused guilty of multiple murder (three deaths) complexed with attempted murder (Noemi), and imposed the supreme penalty of death under RA 7659 (applying Art. 48 of the Revised Penal Code to complex crimes). The trial court also recorded an oral stipulation on the civil aspect purportedly reducing civil liability to P600,000.00 as agreed between counsel and ratified by the private complainant; the court accepted that stipulation and dispensed with the civil testimony.
Supreme Court Review: Credibility Determination
On automatic review, the Supreme Court deferred to the trial court’s primary assessment of witness credibility and affirmed the trial court’s acceptance of Ruben’s testimony. The Court reasoned that: (1) Ruben’s in-court testimony merely supplied details not in his earlier affidavit and was not substantially inconsistent; (2) any minor inconsistencies were immaterial and did not discredit an otherwise credible witness; (3) Ruben’s admission of resentment against the Ibaos did not necessarily indicate fabrication and could even support his credibility for candidness; (4) alleged jailhouse recantations or admissions were unsupported and implausible in the context offered; (5) the accused’s conduct (failure to investigate the blast despite proximity, absence from the crowd, subsequent flight or delays and surrender patterns) undercut the alibi defense and suggested consciousness of guilt.
Admissibility and Weight of Lie Detector Tests
The Court expressly rejected the proffered polygraph (lie detector) results as a basis for exculpation, noting that polygraph testing has not been accepted by the scientific community as reliably determinative of truth or deception. Therefore, the Court did not place probative value on the favorable polygraph reports presented by the accused.
Conspiracy, Mode of Commission, and Crime Classification
From Ruben’s account of coordinated positions and actions (Jaime and Warlito near the barn, Roche by the mango tree, Oscar executing the throw), the trial court reasonably inferred concerted action and conspiracy. The Court applied the doctrine from People v. Tayo to consider whether the killing was murder qualified by explosion or by treachery. Although treachery was the theory charged and accepted by the trial court, the Court observed that the explosive attack delivered while the victims slept foreclosed defense and escape and supported the characterization as multiple murder complexed with attempted murder under Art. 48, with application of the penalty for the most serious crime in its maximum period.
Legal Characterization of Noemi’s Wounding
The Court sustained the trial court’s characterization of the injuries to Noemi as attempted murder rather than frustrated or consummated murder. Medical testimony showed serious but nonfatal injuries; the physician gave conflicting assessments but did not establish fatal intracerebral hemorrhage or other fatal conditions. Because the accused did not perform all acts necessary to accomplish death, the Court affirmed the attempted murder classification.
Sentencing Outcome and Note on RA 7659 Constitutionality
Applying Article 48 (complex crime) and RA 7659, the Court affirmed the imposition of the supreme penalty of death (as permitted by RA 7659) because the complex crime called for application of the penalty for the most serious offense in its maximum period. The opinion records that four members of the Court viewed RA 7659’s death penalty provision as unconstitutional but nonetheless submitted to the majority ruling that RA 7659 is constitutional; the death penalty was therefore affirmed by majority vote.
Civil Liability and Attorney Compromise: Legal Requirements
The trial court’s acceptance of an oral stipulation by counsel to fix civil liability at P600,000.00 raised legal problems. Under Civil Code

Case Caption, Citation and Procedural Posture
- Citation: 408 Phil. 355 EN BANC; G.R. No. 132676; Decision dated April 04, 2001.
- Parties: People of the Philippines (plaintiff-appellee) versus Jaime Carpo, Oscar Ibao, Warlito Ibao and Roche Ibao (accused-appellants).
- Nature of proceedings: Criminal prosecution for multiple murder complexed with attempted murder arising from a grenade explosion that killed three members of the Dulay family and wounded a fourth.
- Review: The case was automatically elevated to the Supreme Court for review after conviction in the trial court; the Supreme Court affirmed the conviction with modifications to the award of civil damages and addressed ancillary legal issues.
Facts as Found by the Prosecution and Trial Court
- Date, time and setting: On 25 August 1996 at about 8:00 p.m., in Brgy. Baligayan (Pangasinan), an explosion occurred in the Dulay family hut while occupants were asleep.
- Immediate consequence: Explosion resulted in the deaths of Florentino Dulay and two daughters, Norwela and Nissan Dulay; a daughter, Noemi Dulay, sustained wounds but survived.
- Method of attack: A hand grenade was hurled into the bedroom of the Dulay family, producing shrapnel and other explosive remnants at the scene as collected by responding police.
- Single principal identifying witness for prosecution: Ruben Meriales, who testified he observed the accused near the Dulay premises shortly before the explosion and named Jaime Carpo, Warlito Ibao, Oscar Ibao and Roche Ibao as perpetrators.
- Alleged motive recited by witness: Ruben stated that Florentino was killed because he was about to testify against Roche Ibao for the murder of Ruben’s brother Delfin Meriales.
Testimony of Ruben Meriales (Prosecution’s Main Witness)
- Circumstances of observation: On the night of the explosion, Ruben reported that his dogs barked; he checked the disturbance, moved his cow, hid behind bamboo slats in his kitchen, and peeped outside under dim lighting (two bulbs ~3 meters away and moonlight).
- Identification of accused: Ruben testified he saw barangay captain Jaime Carpo and Warlito Ibao stooping near his barn, Roche Ibao standing by the mango tree, and Oscar Ibao approach and lift the sawali mat at the Dulay hut and throw something inside.
- Sequence of events he recounted: Immediately after Oscar allegedly hurled the object, a loud explosion followed; Ruben ran to the Dulay hut, was initially deterred by darkness, returned for a flashlight, then witnessed the carnage and assisted in procuring transport for the injured.
- Post-event actions: Ruben initially refused to give a police statement out of fear the perpetrators would return; he later gave a statement at the police station (stated in the record as occurring on 4 September 1996) naming the four accused.
- Consistency and detail: The trial court found Ruben’s oral testimony straightforward and detailed; court observed that his testimony supplied details not contained in his earlier affidavit and accepted the oral account as more authoritative.
Physical Evidence and Police Investigation
- Responding officers and immediate actions: Police Officer Guillermo Osio, together with other officers, responded the night of 25 August 1996; they recovered several grenade shrapnels and a grenade shifting lever from the scene.
- Witness interviews at scene: Teresita Dulay, weeping and at the scene, indicated suspicion of the accused; Ruben told the responding officer he would give a written statement after the funeral.
- Canvass of houses: Police went to the houses of Warlito Ibao, Oscar Ibao and Roche Ibao (front doors locked, houses padlocked/unoccupied or dark); Roche’s house was peeped into by an officer.
- Documentary exhibits and testimony: Medical certificates and physicians’ testimony were introduced concerning injuries and survivability; exhibits of shrapnel and related items were collected.
Injuries, Medical Testimony and Fatalities
- Fatal victims and causes: Florentino, Norwela and Nissan Dulay died as a consequence of the grenade explosion; Nissan, a five-year-old, died later “due to ‘shock from pains’ caused by the shrapnel wounds in her left shoulder, abdomen and lower extremities.”
- Surviving victim and treatment: Noemi Dulay sustained multiple wounds, was semi-conscious and vomiting when examined by Dr. Emiliano Subido, was ambulatory but transferred to another hospital in Dagupan City due to seriousness and lack of facilities.
- Medical nuance for Noemi: The physician testified conflicting assessments — he indicated Noemi could have died from a shrapnel wound in her head but ruled out “intercerebral hemorrhage”; he estimated potential physical incapacity for ten to fourteen days and concluded none of her wounds were fatal.
Charges, Arrests and Pretrial Proceedings
- Criminal complaint: On 3 October 1996 a criminal complaint charging murder of Florentino and his two daughters, and frustrated/attempted murder of Noemi, was filed based solely on Ruben’s testimony.
- Warrants and arrests: Warrants issued by the municipal circuit trial court; Jaime Carpo arrested on 25 October 1996; Roche Ibao eluded arrest until 9 December 1996 (apprehended in La Union); Oscar and Warlito subsequently surrendered to the NBI in La Union.
- Trial witnesses for the prosecution: Ruben Meriales, Noemi Dulay, Dr. Rosalina O. Victorio, Dr. Emiliano Subido, and Police Officers Virgilio dela Cruz, Jovencio Tapac and Guillermo Osio testified for the prosecution.
Defense Theory, Alibi and Witnesses for the Accused
- Core defense plea: The accused interposed alibi, asserting they were elsewhere at the time of the explosion and denied participation; they also accused Ruben of fabrication arising from a grudge.
- Specific alibi assertions:
- Jaime Carpo and his wife Veronica testified Jaime was at home in Brgy. Libsong (~150 meters from Brgy. Baligayan) when the explosion occurred; he sent tanods to check, learned the blast occurred in Baligayan, and went home to sleep. The creek separating the barangays was neck-deep that night and would require a detour of about thirty minutes to cross.
- Warlito, Oscar and Roche Ibao testified they were attending a family farewell party for Maribel Ibao on the night of the explosion; they denied responding to police calls about an hour after the blast and claimed they learned of the incident only the following morning.
- Roche testified he had no house in Brgy. Baligayan per one police report, asserting he lived with parents-in-law in Brgy. Libsong and slept that night at his parents’ house because many relatives were assembled.
- Characterization of Ruben’s motive by defense: Defense asserted Ruben bore resentment against the Ibaos because Roche was a suspect in the murder of Ruben’s brother Delfin, thus Ruben would have motive to lie.
Trial Court’s Findings on Credibility and Conviction
- Credibility assessment: The trial court gave full credit to Ruben’s testimony, describing it as straightforward and noting that no twitch of falsehood was observed in his twin testimonies.
- Rejection of defense: The trial court rejected the alibi and motive-based impeachment, finding inconsistencies and suspicious behavior on the part of the accused (failure to investigate the blast, their immediate departure/tarrying in La Union) that undermined their defense.
- Conspiracy and participation: The trial court found that Jaime, Warlito and Roche positioned themselves in ways that encouraged Oscar to act as the primary perpetrator, and that the four conspired in the commission of the offense.
