Treachery and the Aswang Defense: Understanding Murder Convictions in the Philippines

A 1997 Supreme Court ruling explains how treachery qualifies killings as murder, even when superstition—the (folkloric evil creatures).


The attackers shot the group at close range. William, Endralin, and Juliet died. Rodillo survived, though a bullet remained lodged in his body. He later identified all seven accused and testified that he had no prior quarrel with any of them.

The Issue

The accused appealed their murder and frustrated murder convictions, arguing that the trial court erred in relying on Rodillo's identification. They claimed it was too dark for him to have seen them clearly. The Supreme Court had to determine whether the prosecution proved guilt beyond reasonable doubt, and whether the killings were properly qualified as murder.

The Ruling

The Supreme Court affirmed the convictions. The Court found Rodillo's identification credible: the victims carried torches and a flashlight that remained lit during the attack, the assailants stood very close (Rodillo was shot from about two feet away), and Rodillo had known all seven accused personally for years as neighbors. Against this positive identification, the accused's alibis—claims that they were at home asleep, or elsewhere—failed. For alibi to prosper, the Court explained, the accused must show not only that they were elsewhere, but that it was physically impossible for them to be at the crime scene.

Treachery, Not Evident Premeditation

The Court upheld the finding of treachery (alevosia) under Article 14, paragraph 16 of the Revised Penal Code. Treachery exists when the offender employs means that directly and specially ensure the execution of the crime without risk to the offender from any defense the victim might offer. Here, the victims were unarmed, outnumbered seven to one, and pleading for their lives when the accused opened fire. They had no chance to resist.

The Court also noted a special rule: the killing of a child of tender years is considered attended by treachery even if the exact manner of attack is not shown, because a young child cannot reasonably be expected to defend herself.

However, the Court rejected the trial court's finding of evident premeditation. To prove this aggravating circumstance, the prosecution must show: (1) when the offender decided to commit the crime, (2) an act manifesting that the offender clung to that decision, and (3) a sufficient lapse of time between the decision and execution for reflection. Here, there was no evidence of any planning. Rodillo himself testified he knew of no reason for the attack until it happened.

Nighttime as an Aggravating Circumstance

The Court also upheld the appreciation of nighttime as a generic aggravating circumstance. The accused ordered the victims to put out their lights, showing they deliberately sought darkness to facilitate the crime and ensure impunity. Notably, the Court held that nocturnity was not absorbed by treachery in this case because the treachery rested on an entirely different basis—the victims' defenselessness—not the darkness.

Practical Takeaways

  • Positive identification beats alibi. Courts give great weight to a witness who knew the accused personally and had ample opportunity to see them during the crime. Alibi must prove physical impossibility, not mere absence.
  • Treachery is about the method of attack. If the attack is designed to prevent any defense, the killing is murder regardless of motive—even a motive rooted in superstition like the "aswang" belief.
  • Evident premeditation requires proof of planning. Courts will not infer it from the crime itself; the prosecution must show when the decision was made and that the offender persisted in it.
  • Killing a child is almost always treacherous. The law presumes treachery when the victim is of tender years and inherently defenseless.
  • Nighttime can be a separate aggravating circumstance. If the accused deliberately used darkness to commit the crime with impunity, nocturnity may be appreciated on top of treachery.
