When Treachery Is Not Proven: How a Murder Charge Becomes Homicide

The difference between murder and homicide often turns on a single detail: how the attack began. In People v. Aviles (G.R. No. 172967, December 19, 2007), the Supreme Court reduced a murder conviction to homicide after finding that the prosecution failed to prove treachery beyond reasonable doubt. The case is a useful reminder that qualifying circumstances are not presumed — they must be established with the same rigor as the crime itself.

The stabbing on Alexander Street

On the evening of June 19, 2002, Novelito Contapay was driving his passenger jeepney slowly along Alexander Street in Urdaneta City, Pangasinan, because of heavy traffic. Danilo Arenas sat beside him. Without warning, Arenas shouted "Apaya." Contapay turned and saw Christopher Aviles stabbing Arenas, with Aviles already partly inside the jeepney.

Contapay stopped the vehicle and tried to hold Aviles, but Aviles stabbed him in the left knee. Contapay pushed Aviles away, and the assailant fled. Arenas was rushed to the hospital but died early the next morning from hemorrhagic shock caused by a severed branch of the femoral artery. Contapay was treated for his knee wound.

Aviles denied the stabbing, claiming his half-brother George Cresencia had committed it. The trial court convicted him of murder and slight physical injuries. The Court of Appeals affirmed with modification.

The lone eyewitness and the credibility question

Aviles argued that Contapay's identification was unreliable. The two did not know each other before the incident, and Aviles claimed that a person in Contapay's position would focus on the struggle rather than on recognizing the attacker.

The Supreme Court rejected this. It held that there is no standard human reaction to a startling or frightful experience. Citing People v. Aquino (385 Phil. 887, 906 [2000]), the Court noted that the face and movements of an assailant often leave an impression that cannot easily be erased from a witness's memory. Since Contapay did not know Aviles before the incident, he could not have been moved by ill will in identifying him.

Why treachery failed

Treachery requires two things: the use of means, methods, or manner of execution that ensure the offender's safety from any defensive or retaliatory act by the victim, and the deliberate or conscious adoption of that manner of execution. Both must be proven beyond reasonable doubt.

Here, the prosecution could not show how the attack began. Contapay only turned after hearing Arenas shout "Apaya," and he was driving at the time, so he could not have seen the inception of the assault. The Court also rejected the Court of Appeals' reading of "Apaya" as an expression of surprise. Translated more accurately as "Bakit ba," the shout suggests confusion and implies that several moments had passed between the start of the attack and the shout.

Treachery must be present at the inception of the attack. If it appears only at a later stage, it cannot qualify the killing. The Court also pointed to the autopsy finding of a defensive wound on the victim's wrist, which suggested a possible struggle. The fact that Arenas was seated between Contapay and Aviles, while fatal, did not prove that Aviles deliberately chose that position to ensure his safety.

From murder to homicide

With treachery excluded, no qualifying circumstance attended the killing. Aviles could only be convicted of homicide, which the Court described as punishable by reclusion temporal. With no mitigating or aggravating circumstances, the penalty was imposed in its medium period.

Applying the Indeterminate Sentence Law, the Court set the minimum at 10 years and one day of prision mayor and the maximum at 14 years and one day of reclusion temporal. The conviction for slight physical injuries was affirmed, as the prosecution failed to prove intent to kill in the stabbing of Contapay. The award of exemplary damages was deleted because no qualifying circumstance was established.

Practical takeaways

• A murder charge depends on proving a qualifying circumstance such as treachery beyond reasonable doubt — the same standard used for the crime itself.
• Treachery must be shown at the inception of the attack; evidence of surprise or a sudden assault is not automatically enough.
• A lone eyewitness can be credible, especially where the witness and the accused were strangers before the incident.
• The absence of intent to kill may reduce a stabbing charge to slight physical injuries, particularly where the injury's extent and the period of incapacity are not proven.
• When a qualifying circumstance is removed, the penalty drops, and so do the corresponding civil awards such as exemplary damages.
