Complex Crimes: When One Act Causes Multiple Fatalities Under Philippine Law

The Supreme Court's 1997 decision in People v. Tabaco (G.R. Nos. 100382-85, 336 Phil. 771) provides a clear illustration of how Philippine criminal law treats a single act that results in multiple fatalities. The case is frequently cited for its discussion of complex crimes, and it offers practical guidance on how courts determine liability when one pull of the trigger kills several people.

The Facts of the Case

On the evening of March 22, 1987, Mario Tabaco, a member of the Philippine Constabulary, attended a cock derby at the Octagon Cockpit Arena in Aparri, Cagayan. Tabaco was in civilian clothes but carried his official M-14 rifle.

At around 10 p.m., without warning or provocation, Tabaco stood up from his seat and fired successive automatic bursts from his rifle toward the group of former Mayor Jorge Arreola, who was seated about three to five meters away. The gunfire killed four people: Mayor Arreola, Capt. Oscar Tabulog, Felicito Rigunan, and Pat. Romeo Regunton.

A separate incident followed when Tabaco rushed out of the arena. As he was being disarmed by fellow peace officers, the gun went off, killing Jorge Siriban, Jr. and wounding Sgt. Benito Raquepo.

Tabaco was charged in five separate informations: four counts of murder for the four fatalities in the cockpit, and one count of homicide with frustrated homicide for the death of Siriban and the wounding of Raquepo.

The Legal Issue

The central issue before the Supreme Court was whether the trial court correctly treated the four deaths from the initial burst of gunfire as a single complex crime rather than four separate murders.

Under the Revised Penal Code, when a single act constitutes two or more grave or less grave felonies, or when an offense is a necessary means for committing another, the penalty for the most serious offense is imposed in its maximum period. This is known as a complex crime.

The Court's Ruling

The Supreme Court affirmed the trial court's conviction of Tabaco. The Court held that the four deaths resulting from the single burst of automatic gunfire constituted one complex crime—specifically, the complex crime of multiple murder, for which the accused was sentenced to a single penalty of reclusion perpetua in its maximum period.

Because the four victims were killed by one continuous act of firing, the Court treated the incident as a single felony with multiple consequences. The penalty imposed was a single sentence rather than four separate penalties for four separate murders.

For the second incident—the death of Siriban and the wounding of Raquepo—the Court treated this as a separate complex crime of homicide with frustrated homicide.

Why the Distinction Matters

The distinction between separate crimes and a complex crime has significant practical consequences for sentencing. Had the four deaths been treated as four separate murders, the accused would have faced four separate penalties. Instead, the Court imposed a single penalty for the complex crime.

The Court also emphasized the importance of the trial court's assessment of witness credibility. Where prosecution witnesses positively identified the accused as the shooter, and the defense offered only bare denial, the trial court's findings are generally respected on appeal.

Practical Takeaways

• A single act causing multiple deaths is one complex crime, not multiple separate crimes. The penalty for the most serious offense is imposed in its maximum period.
• The prosecution may charge multiple offenses in one information when they arise from a single act. In this case, the four murder charges were consolidated into one complex crime charge.
• Positive identification by eyewitnesses carries more weight than bare denial. Courts generally defer to the trial court's credibility findings unless there is a clear error or overlooked fact.
• The distinction between complex and separate crimes affects sentencing significantly. Understanding this doctrine is essential for both prosecutors and defense counsel in crafting charges and penalties.
• The complex crime rule applies only when the offenses are grave or less grave felonies. The rule does not apply to light felonies.
