Accountability FOR ALL Establishing Conspiracy IN Robbery With Homicide

A conviction for robbery with homicide does not require each conspirator to wield the weapon. Presence and common purpose suffice.


In robbery with homicide, every participant in the robbery is liable for the killing that occurs on the occasion of it — even if only one of them actually stabbed the victim. The Supreme Court affirmed this principle in People v. Villanueva, Jr. (G.R. No. 187152, July 22, 2009), clarifying how conspiracy is established and why mere presence at the crime scene can be enough to convict.

What happened in the case

On the morning of December 6, 2002, a group of men entered a house in Pasig City while the occupants — three minors — were still asleep. The men took jewelry and a cellphone worth P90,000. One of the intruders attempted to molest the 16-year-old girl, who resisted and was stabbed. Her 11-year-old brother was killed; her 15-year-old brother was also stabbed but survived.

The accused, Teodulo Villanueva, Jr., was identified by the two surviving victims as one of the intruders. One witness saw him holding her younger brother before the co-accused stabbed the child. The other witness saw him in the living room while the house was in disarray. Villanueva denied involvement, claiming he was sleeping at home at the time.

The issue: Was there conspiracy?

Villanueva argued that mere presence at the crime scene is not enough to prove conspiracy. He insisted that the prosecution failed to show he shared a common design with the others to commit robbery with homicide.

The Supreme Court disagreed. Conspiracy need not be proved by direct evidence; it may be inferred from the conduct of the accused before, during, and after the crime. Overt acts showing concerted action and unity of purpose suffice.

Here, the accused was a stranger with no business in the victims' house. He was seen inside the house during the robbery, holding one of the victims as the co-accused stabbed him. He fled with the others and the loot, leaving the minors wounded and helpless. He gave no aid and did not report the incident. These acts, taken together, showed he was part of a common plan — not an innocent bystander.

The "act of one is the act of all" rule

Once conspiracy is established, it no longer matters who actually killed the victim. The Court cited the settled rule: when homicide occurs by reason or on the occasion of a robbery, all who took part in the robbery are guilty of the special complex crime of robbery with homicide, whether or not they personally participated in the killing — unless they proved they tried to prevent it. Villanueva presented no such proof.

Alibi and inconsistent affidavits

The Court also rejected the defense of alibi. For alibi to prosper, the accused must show it was physically impossible for him to be at the crime scene. Villanueva's house was only about 100 meters away — a few minutes' walk. His alibi was not airtight.

On the alleged inconsistencies between the witnesses' affidavits and their court testimonies, the Court noted that affidavits are usually incomplete and taken under stressful conditions. The witnesses explained they were confused and worried about their wounded siblings when their statements were taken. Their positive, categorical identification of the accused in court prevailed.

The penalty and damages

Robbery with homicide is a single indivisible offense under the Revised Penal Code, punishable by reclusion perpetua to death. Treachery attended the killing, which would have qualified the penalty to death, but the Court imposed reclusion perpetua because Republic Act No. 9346 (2006) prohibits the death penalty.

The Court increased the awards: P75,000 civil indemnity, P75,000 moral damages, and P30,000 exemplary damages, plus restitution of the stolen items or payment of P90,000.

Practical takeaways

  • Conspiracy can be inferred from circumstances. Direct proof of an agreement is not required; acts showing unity of purpose are enough.
  • Presence is not always innocent. Being at the crime scene without a legitimate reason, especially while crimes are being committed, can establish conspiracy.
  • All conspirators are equally liable. In robbery with homicide, the act of one is the act of all, regardless of who actually killed.
  • Alibi rarely succeeds. It must show physical impossibility of presence, not mere denial.
  • Affidavit inconsistencies are not fatal. Courts give more weight to clear court testimony, especially when the witness explains the confusion.
