People vs. Buyco

When a single pull of a submachine gun’s trigger results in multiple deaths, the deaths caused by that single mechanical discharge constitute a complex crime under Article 48 of the Revised Penal Code, punishable by the penalty for the most serious crime in its maximum period; however, a death caused by a separate and distinct pull of the trigger constitutes a separate felony.

Incident occurred during the feast of the patron saint of barrio Trapiche, municipality of Oton, Iloilo, on February 22, 1946, where a public dance was being held and Military Police personnel were on patrol.

• Filed in the Court of First Instance (CFI) of Iloilo, Criminal Case No. 405
• Decision of lower court: Rendered May 8, 1946; convicted Buyco of triple murder and imposed reclusion perpetua with civil indemnity
• Elevated to SC: Automatic review or appeal by accused-appellant

• Nature of action: Criminal prosecution for multiple homicides
• Parties:
  • Accused-appellant: Meliton Buyco, first-class private, Military Police (MP)
  • Victims: Apolonio Ikoy, Irineo Gellangala, Napoleon Zambales
• Factual events:
  • During a dance at barrio Trapiche, a fist fight broke out between Cornelio Soliman and another individual; Municipal Police Chief Eusebio Davila intervened to pacify the fighters
  • Apolonio Ikoy entered the fray and knocked Soliman down
  • Buyco, on patrol with six MP companions, fired two warning shots in the air with his Thompson submachine gun; Davila prohibited further firing, but Buyco refused
  • Buyco seized Ikoy by the back/left shoulder, pushed him forward, and fired a burst at Ikoy’s back, killing him instantly
  • A bullet from the same burst struck Irineo Gellangala (who was in almost a straight line from Ikoy), killing him instantly
  • Buyco then turned, faced another direction, and fired a second burst at a group including Napoleon Zambales, hitting the latter; Zambales died six days later in St. Paul’s Hospital
  • Davila attempted to arrest Buyco but was threatened with the submachine gun and warned away from helping the wounded
  • Autopsy findings confirmed deaths resulted from submachine gun wounds
  • Defense version: Claimed Ikoy wrested Corporal Taleon’s rifle and was aiming it at the corporal when Buyco fired in defense of Taleon; claimed flight was due to fear of reprisal from Ikoy’s relatives
  • Trial court findings: Rejected defense testimony as fabricated, inconsistent with prior statements (Exhibit E), and improbable; noted Taleon’s prior statement to the fiscal indicated Ikoy never succeeded in wresting the gun

• The defense version is incredible and contradicted by Exhibit E (Taleon’s prior statement that Ikoy did not get the gun)
• Flight of the MP patrol indicates guilty conscience, not legitimate law enforcement
• Treachery attended the killing of Ikoy (attacked from behind, no chance to defend)
• The single mechanical burst killing Ikoy and Gellangala constitutes a complex crime of murder and homicide under Article 48 RPC
• The separate shot killing Zambales is a distinct homicide, not part of the complex crime

• He acted in defense of a stranger (Corporal Taleon) to prevent Ikoy from shooting the corporal with his own rifle
• The deaths of all three victims resulted from a single act of firing, thus should be treated as one transaction or complex crime
• It is implausible he would kill three persons without justification unless acting in defense
• The trial court erred in rejecting the testimony of defense witnesses who supported the defense of stranger theory

• Procedural Issues: N/A
• Substantive Issues:
  • Whether the defense of stranger was sufficiently proven to justify the killings
  • Whether the killing of Apolonio Ikoy was murder qualified by treachery or merely homicide
  • Whether the killing of Irineo Gellangala (unintended victim of the same burst) constitutes homicide under Article 4(1) RPC (aberratio ictus)
  • Whether the deaths of Ikoy and Gellangala from a single trigger pull constitute a complex crime under Article 48 RPC
  • Whether the killing of Napoleon Zambales (from a separate burst) is a distinct crime or part of the complex crime
  • Whether the death penalty should be imposed for the complex crime of murder and homicide

• Procedural: N/A
• Substantive:
  • Defense of stranger: Not proven. The trial court’s factual findings on witness credibility stand. Taleon’s prior statement to the fiscal contradicted his trial testimony that Ikoy wrested the gun. The story of Ikoy attacking an armed MP corporal and wresting his weapon is inherently improbable. Flight of the accused and his companions indicates fear of accountability, not legitimate duty. Once the accused admits the killing, the burden shifts to him to prove the justifying circumstance, which he failed to discharge.
  • Killing of Ikoy: Murder qualified by treachery (alevosia). Buyco seized Ikoy from behind, pushed him forward, and shot him as he was falling, employing means that insured execution without risk to himself from any defense the victim might make (Art. 248 RPC).
  • Killing of Gellangala: Homicide under Article 4(1) RPC (aberratio ictus/error in personae). The act causing Gellangala’s death was the same single burst intended for Ikoy. Although the victim was unintended, the wrongful act committed is a felony for which the accused is criminally liable because all acts are presumed voluntary.
  • Complex crime: The deaths of Ikoy and Gellangala constitute a complex crime of murder and homicide under Article 48 RPC because they resulted from a single act (one pull of the submachine gun trigger set to fire multiple bullets automatically in succession).
  • Killing of Zambales: Separate homicide. Death resulted from a second, distinct pull of the trigger (different burst) aimed at a different group. Article 48 requires a single act; successive shots at different persons constitute separate felonies (citing Spanish Supreme Court jurisprudence and Viada).
  • Penalty: For the complex crime (murder + homicide), the penalty is the capital offense (death) in its maximum period; however, due to lack of unanimity among the justices, the penalty is lowered to reclusion perpetua. For the separate homicide of Zambales (no modifying circumstances), the penalty is reclusion temporal in its medium period; applying the Indeterminate Sentence Law (Act No. 4103, as amended by Act No. 4225), the sentence is 6 years and 1 day of prision mayor to 14 years, 8 months and 1 day of reclusion temporal.

• Aberratio ictus (Error in personae) under Article 4(1) RPC — When a wrongful act is committed against a person different from the intended victim, the offender is criminally liable for the actual felony committed (not the intended one) because all acts are presumed voluntary and the law holds the aggressor responsible for all consequences of his unlawful act. Applied to hold Buyco liable for homicide for Gellangala’s death despite the shot being intended for Ikoy.
• Treachery (Alevosia) — Qualifying circumstance under Article 248 RPC consisting of the employment of means, methods, or forms in the execution of the crime which tend directly and specially to insure its execution without risk to the offender from the defense the offended party might make. Applied here because Buyco seized Ikoy from behind and shot him as he was pushed forward, eliminating any possibility of defense.
• Complex Crime under Article 48 RPC — When a single act constitutes two or more grave or less grave felonies. Requisites: (1) a single act; and (2) two or more grave or less grave felonies committed thereby. Applied to the single mechanical discharge (one trigger pull) killing Ikoy (murder) and Gellangala (homicide).
• Successive Acts Doctrine — Successive shots fired at different persons by distinct trigger pulls constitute separate, distinct crimes, not a complex crime under Article 48. Applied to distinguish the killing of Zambales (separate burst) from the Ikoy-Gellangala killings (single burst).
• Burden of Proof in Justifying Circumstances — Once the accused admits the killing, the burden of proof shifts to him to establish the justifying circumstance (e.g., defense of stranger) to the satisfaction of the court; failure to discharge this burden results in conviction because the law presumes malicious intent (malice in law).

• "Having thus admitted that he killed the victim, it was incumbent upon the accused to offer a justification satisfactory to the courts to exculpate him." — On burden shifting when killing is admitted.
• "While motive is generally of great importance in a criminal case, it is not absolutely indispensable. The evidence in the case relating to the actual commission of the crime may be so overwhelming that the question of motive may become secondary." — On motive vs. proof of commission.
• "All acts punishable by the law are presumed to be voluntary in the absence of proof to the contrary. With respect to crimes of personal violence, the penal law looks particularly to the material results following the unlawful act and holds the aggressor responsible for all the consequences thereof." — On Article 4(1) and aberratio ictus.
• "Although the wrongful act be committed against a person other than the one whom it was intended to injure, this fact does not excuse the offender from criminal liability for the voluntary commission of a wrongful act or misdemeanor, according to paragraph 3 of article 1 of the Penal Code [Now art. 4 of Revised Penal Code]." — On error in personae.
• "The evidence discloses that, while Apolonio Ikoy had his back towards Meliton Buyco, the defendant-appellant, the latter got hold of the former's right shoulder, pushed him forward and while Ikoy's body was moving in the direction of the push, Buyco fired at his back... the aggressor employed means, methods or forms in the execution of the crime which tended directly and specially to insure its execution without risk to himself from the defense which the offended party might make." — On treachery.

• U.S. vs. Ricafort, 1 Phil. 173 — Followed for the principle that when the defense (of justification) fails, the law presumes the killing was intentional/malicious because the act itself is wrongful.
• U.S. vs. McMann, 4 Phil. 561 — Followed for the principle that motive is less important when the identity of the perpetrator and the fact of commission are proven beyond doubt.
• U.S. vs. Balmori, 18 Phil. 578 — Followed for the principle that motive is not indispensable when evidence of actual commission is overwhelming.
• U.S. vs. Diana, 32 Phil. 344 — Controlling precedent for Article 4(1) RPC; establishes that unintended victim’s death constitutes the felony actually committed (homicide), and intent to injure a different person is irrelevant to criminal liability for the actual result.
• U.S. vs. Gloria, 3 Phil. 333 — Cited for the presumption of voluntariness of criminal acts.

• Article 248, Revised Penal Code (Murder) — Defines murder and lists treachery as a qualifying circumstance. Applied to classify Ikoy’s death as murder.
• Article 249, Revised Penal Code (Homicide) — Defines homicide. Applied to classify Gellangala’s and Zambales’ deaths as homicide.
• Article 4, paragraph 1, Revised Penal Code — Provides that criminal liability is incurred by any person committing a felony (delito) although the wrongful act done be different from that which he intended (aberratio ictus). Applied to Gellangala’s death.
• Article 48, Revised Penal Code (Complex Crimes) — Provides that a single act constituting two or more grave or less grave felonies results in a complex crime punishable by the most serious offense in its maximum period. Applied to the single burst killing Ikoy and Gellangala.
• Act No. 4000 — Amendment to Article 48 regarding the imposition of the capital penalty in its maximum period for complex crimes.
• Act No. 4103 (Indeterminate Sentence Law) — Applied to determine the minimum and maximum range for the separate homicide of Zambales.
• Act No. 4225 — Amendment to the Indeterminate Sentence Law, referenced regarding the penalty range.

N/A (The judgment notes a lack of unanimity among the justices regarding the imposition of the death penalty, resulting in the lowering of the sentence to reclusion perpetua, but no dissenting opinion is reproduced in the text.)
