Case Summary (G.R. No. 156337)
Factual Background
At about 10:00 p.m. on May 22, 1994, witnesses Antonio Altarejos and Antonia Eluzon observed a van belonging to neighbor Alejandro Patungan parked by a chapel and saw two men inside, later identified as accused Elmerto Pulga and Edgar Acebuche. The van was later moved to a vacant lot near Commonwealth Avenue. At about 3:00 to 3:30 a.m. on the following morning the couple observed Alejandro and his wife Marietta Patungan at the house; Marietta returned indoors while Alejandro proceeded alone. On May 24, 1994 the decomposing body of Alejandro Patungan was discovered inside his van parked in Sampaloc, Manila.
Autopsy Findings
The medico-legal officer who autopsied the cadaver on May 24, 1994 reported advanced decomposition with bloating, bullae formation, and greenish discoloration. External injuries included a stab wound entering the left cheek and exiting the left sub-mandibular region, a ligature mark around the neck, eight puncture wounds in the left lateral neck and supra/infra-clavicular region, and 51 puncture wounds distributed in the abdomen. Internal findings included lacerations of subcutaneous tissues, three stab wounds in the upper lobe of the left lung with massive left thoracic bleeding, and injuries to the liver, stomach, spleen, intestines, kidneys, inferior vena cava and abdominal aorta with massive peritoneal bleeding. The cause of death was certified as multiple stab wounds and ligature strangulation, and the medico-legal officer estimated the victim had been dead about thirty-six hours prior to the May 24 autopsy.
Information and Charges
An Information dated August 16, 1994 charged Marietta Patungan y Pulga with parricide under Article 146, and Edgar Acebuche y Cervito and Elmerto Pulga y Acebuche with murder under Article 248, alleging conspiracy, evident premeditation and treachery, and alleging the use of a motor vehicle and strangulation with an electric wire as modes of commission.
Trial Proceedings
All three accused entered pleas of not guilty. The prosecution presented eyewitness testimony of Antonio and Antonia, the autopsy report, testimony of police officers, and an extra-judicial confession attributed to Elmerto Pulga executed on August 11, 1994 at the Integrated Bar of the Philippines (IBP) office. The defense presented testimony denying participation, allegations of custodial interrogation without counsel, and specific repudiation by Elmerto Pulga claiming torture and coercion.
Prosecution Evidence
The prosecution relied principally on the alleged extra-judicial confession of Elmerto Pulga, which linked Marietta as mastermind and Edgar as the triggerman. The confession described a plan hatched by Marietta and her lover to eliminate Alejandro, and detailed the killing inside the van. Prosecution witnesses also testified to Marietta’s alleged affair and motive, and to funeral expenses of PHP 80,000 which the defense admitted.
Defense Evidence
Marietta Patungan testified that she accompanied her husband in the early dawn to buy flowers but returned home to fetch a videotape and that Alejandro proceeded alone. Edgar Acebuche denied involvement and testified he was mistaken for another person and arrested. Elmerto Pulga repudiated the written confession and testified that he was arrested or taken into custody, blindfolded, bound, and subjected to electrocution by police until he signed a prepared document; he claimed intimidation and inability to complain while in custody.
Extra-judicial Confession and Custodial Circumstances
The Supreme Court examined at length the circumstances of Elmerto Pulga’s confession against the constitutional backdrop of Art. III, Sec. 12(1), 1987 Constitution, which guarantees the right to counsel during custodial investigation and renders involuntary confessions inadmissible. Police testimony revealed that Pulga was questioned in custody for approximately two and a half days without counsel before being brought to the IBP office. The IBP lawyer who attested to the written confession conceded he was largely inattentive and worked on another matter during the taking of the statement. Conflicting police testimony conceded that no counsel assisted Pulga from the start of custodial questioning. Given these facts and Pulga’s credible account of coercion and fear while in police custody, the Court held that the assistance of counsel was neither effective nor independent and that the written confession was the product of an uncounselled, coercive custodial environment.
Trial Court Judgment
The trial court accepted the extra-judicial confession as valid, found the three accused guilty beyond reasonable doubt — convicting Marietta Patungan of parricide and Elmerto Pulga and Edgar Acebuche of murder with attendant circumstances of treachery and evident premeditation — sentenced them to death, and ordered joint and several indemnity and damages of P50,000, P80,000, and P50,000 respectively.
Issues on Appeal
On automatic review the Court confronted two principal issues: the admissibility and voluntariness of Elmerto Pulga’s extra-judicial confession under Art. III, Sec. 12(1), 1987 Constitution, and whether the remaining evidence, apart from that confession, sufficed to prove conspiracy and the participation of Marietta and Edgar in the killing with the qualifying circumstances alleged.
Supreme Court’s Analysis on the Confession
The Court reaffirmed the settled rule that an extra-judicial confession is admissible only if it is express, voluntarily executed in writing, and made with the assistance of an independent and competent counsel who effectively protects the accused’s constitutional rights. The Court found that Pulga was subjected to custodial interrogation without counsel for an extended period; that his initial denials and pointing to another suspect negated any claim of voluntary surrender; and that the IBP lawyer’s inattentive participation did not satisfy the constitutional requirement of effective assistance. The Court therefore excluded Pulga’s extra-judicial confession as inadmissible.
Supreme Court’s Findings on Conspiracy and Presence of Accused
With the confession excluded, the Court considered the remaining evidence. The Court found that eyewitness testimony established only that Pulga and Edgar were seen in the van earlier that night, and that Marietta and Alejandro were seen together hours later. The medico-legal estimate of time of death and the absence of proof that Pulga and Edgar remained with the victim at the critical hour undermined the prosecution’s inference of a continuing conspiracy. The Court further held that alleged motive and an unproven attempted suicide by Marietta were insufficient to establish her guilt. On this record, the Court concluded the prosecution had failed to prove conspiracy or the participation of Marietta and Edgar beyond reasonable doubt and acquitted them of the crimes charged.
Ruling on Elmerto’s Liability and Penalty
The Court sustained only Elmerto Pulga’s judicial admissions made in open court in which he acknowledged stabbing Alejandro and losing control, testimony that corresponded to autopsy findings of three stab wounds in the upper body and multiple wounds in the abdomen as well as left-sided injuries consistent with Pulga’s
