Facts:
The case revolves around Jaime Tumaru and Alex Maun, who were accused of the murder of Atty. Eduardo Madrid and Santiago Umoso on May 24, 1987, in Malubibit, Flora, Kalinga-Apayao. The prosecution filed charges against the appellants, citing that they conspired to kill both victims with treachery and evident premeditation. The series of events began when Atty. Madrid and Umoso were ambushed while riding a motorcycle. Several witnesses testified to seeing the accused at the scene. Lorenzo Miguel, a key prosecution witness who was unaware of the assailants' identity until later, described hearing gunshots and witnessing the aftermath. Autopsies established the brutal nature of the murders, with Atty. Madrid’s head being severed from his body, and multiple gunshot wounds on Umoso. The Regional Trial Court, after a joint trial that commenced on November 29, 1988, found Tumaru and Maun guilty, imposing reclusion perpetua and requiring them to pay indemnities to the heirs of the

Facts:
- Indictment and Charges
- The appellants, Jaime Tumaru and Alex Maun, were indicted in two separate criminal cases—Criminal Case No. 15-88 for the murder of Atty. Eduardo Madrid and Criminal Case No. 16-88 for the murder of Santiago Umoso.
- The Informations allege that on May 24, 1987, at Malubibit, Flora, Kalinga-Apayao, the accused, armed with guns and acting in concert with evident premeditation, attacked the victims with treachery.
- The crimes were committed “contrary to law” and were further aggravated by circumstances such as ignominy.
- Incident Details and Testimonies
- On the afternoon of May 24, 1987, during a seemingly routine activity, events took a drastic turn when, according to witness Lorenzo Miguel:
- He was pasturing carabaos when a man on a tree branch signaled him, an action he initially dismissed as being from his brother until later identifying the man as Alex Maun.
- Shortly thereafter, a motorcycle carrying Municipal Councilor Santiago Umoso and OIC Mayor Eduardo Madrid was involved; testimonies indicate that Atty. Madrid was shot severely—resulting in fatal injuries—while Umoso also sustained a gunshot wound leading to his death.
- Subsequent identifications were made through in-court line-ups and meticulous photographic comparisons.
- The prosecution presented an array of witnesses, including family members, police officers, and medical personnel, detailing not only the sequence of events but also specific descriptions such as the clothing worn by the accused and the layout of the crime scene.
- Evidence and Forensic Findings
- Witness Testimony:
- Lorenzo Miguel provided a detailed account of the events, including noticing unusual behavior from the accused and later identifying them during a lineup.
- Other witnesses corroborated aspects of the incident, such as the recovery of the victims’ bodies and the identification process following the shootings.
- Medical and Autopsy Reports:
- The autopsy on Atty. Eduardo Madrid revealed gunshot wounds, including a complete avulsion of the head and neck, alongside other fatal injuries.
- The autopsy on Santiago Umoso detailed a gunshot wound at the head (with entrance and exit specifications) and a separate chest wound, confirming the direct impact of the assailants’ actions.
- Investigative Chronology:
- The investigation was promptly conducted by police and investigators that include NBI agents and members of the INP.
- Evidence included sworn statements, photographs, and recovered material evidence (e.g., the motorcycle and physical evidence from the crime scene).
- Procedural and Trial Developments
- The accused entered negative pleas at arraignment on November 29, 1988, with defense counsel assisting in their presentation.
- During the joint trial, while the prosecution built its case through a variety of witnesses and forensic evidence, the defense attempted to establish alibi and denied any involvement, even attributing the murders to the NPAs.
- The trial record shows extensive cross-examination, wherein witness credibility—especially that of Lorenzo Miguel—was rigorously questioned, including issues regarding bias given his later association with the victim’s family.
- Defense Claims and Alibi
- The defense maintained that Tumaru and Maun were not involved in the murders, asserting a denial of participation and offering an alibi based on an intelligence mission purportedly ordered by their commanding officer.
- Notable points in the defense’s narrative included:
- A claim that the accused left Luna at 2:00 PM on May 24, 1987, to attend to mission-related tasks elsewhere.
- Testimonies and sworn statements submitted, marked by exhibits, which contended that they were engaged in non-criminal activities during the time of the murders.
- The defense also highlighted potential bias in the primary witness’s testimony by noting his close association with the victim’s family, although the prosecution and later analysis countered these claims.
- Trial Court Decision
- On September 26, 1990, the Regional Trial Court found that the evidence was sufficient to convict Tumaru and Maun in both criminal cases.
- The judgment rendered sentenced both accused to suffer reclusion perpetua in each case and imposed various indemnity costs for damages and expenses incurred by the victim’s families.
- The decision was backed by extensive documentation of the chain of events, witness identifications, forensic reports, and the overall coherence of the prosecution’s case.
Issues:
- Sufficiency and Credibility of Evidence
- Was the trial court justified in basing its conviction primarily on the testimony of the lone eyewitness, Lorenzo Miguel?
- Did the protracted timing of Lorenzo Miguel’s sworn statement and his living arrangement with the victim’s family compromise his credibility?
- Appropriateness of Judicial Process
- Is it proper for a decision to be rendered by a judge who did not originally hear the evidence, particularly when the trial judge was replaced due to various circumstances?
- Does the substitution of the trial judge invalidate or undermine the evaluation of the evidence already presented?
- Evaluation of Defense Arguments
- Was the defense’s reliance on denial and alibi, which included a purported intelligence mission and an assertion of their physical absence from the scene, adequately substantiated?
- Did the trial court commit error by imputing motive to the accused without clear evidentiary support?
- Identification and Forensic Corroboration
- How credible is the positive identification of the accused by the prosecution witnesses, given the circumstances surrounding the lineup?
- Does the forensic evidence, including the autopsy findings, adequately support the identification of the accused as the perpetrators?
