Case Digest (G.R. No. 132376)
Expanded Legal Reasoning Model

Facts:

  • Background of Prison Gangs
    • Since 1956, New Bilibid Prison inmates formed two rival gangs:
      • “Sigue-Sigue” (predominantly Tagalogs) housed in Building 1.
      • “OXO” (predominantly Visayans/Mindanaoans) housed partly in Building 4 (brigade 4-A).
    • Frequent violent clashes led to segregation of rival members into separate buildings and brigades.
  • Events of February 16, 1958
    • About 7:00 a.m., inmates assembled for Sunday mass; a fight between two rival members in the plaza was quelled by guards.
    • A riot erupted in Building 1; Sigue-Sigue inmates attempted to invade Building 4 but were repelled.
    • Shortly thereafter, OXO members in brigade 4-A destroyed their lock, invaded 4-B, and killed Jose Carriego by clubbing and stabbing.
    • The same group forced entry into 4-C, broke in with insider help, and killed Eugenio Barbosa and Santos Cruz by blows and stabbings.
  • Victims’ Injuries and Causes of Death
    • Jose Carriego:
      • Lacerated lower lip; contusion on neck; five chest punctures.
      • Cause of death: internal hemorrhage from chest wounds.
    • Eugenio Barbosa:
      • Occipital laceration; two abdominal penetrating wounds; axillary laceration; bruises.
      • Cause of death: shock and internal hemorrhage.
    • Santos Cruz:
      • Head laceration; fractured skull; lip cut; seven chest punctures; hand hematomas.
      • Cause of death: fractured skull.
  • Prosecution Evidence
    • Brigade 4-B witnesses (Pineda, Marayoc, Sauza) saw Factora club Carriego and Peralta, Dosal stab him.
    • Brigade 4-C witnesses (Fontillas, Pabarlan, Halili, Espino) identified Factora, Peralta, Dosal, Parumog, Larita, Luna in the killings of Barbosa and Cruz.
  • Defendants and Procedural Posture
    • Six review defendants: Amadeo Peralta, Andres Factora, Leonardo Dosal, Angel Parumog, Gervasio Larita, Florencio Luna.
    • Others were dismissed, acquitted, or died; conviction and death sentences of these six were automatically reviewed by the Supreme Court.

Issues:

  • Whether conspiracy existed among the six in planning and executing the three murders.
  • Whether Peralta’s and Dosal’s self-defense claims negate their guilt.
  • Whether Parumog’s, Larita’s, and Luna’s alibi defenses negate their participation.
  • Whether aggravating circumstances (quasi-recidivism, treachery, abuse of superior strength) are present.
  • Whether multiple death penalties are proper for each defendant under the Revised Penal Code.
