The Supreme Court affirmed the conviction of Welvin Diu and Dennis Dayaon for robbery with homicide, underscoring that all participants in a robbery are liable as principals if a homicide occurs during the commission of the crime, regardless of direct involvement in the killing, unless they demonstrably tried to prevent it. This ruling highlights the principle that those who conspire to commit robbery bear the responsibility for the resulting consequences, including unintended loss of life, ensuring accountability and reinforcing the duty to prevent harm.

When Carnival Revelry Turns into a Deadly Conspiracy

The case of People of the Philippines v. Welvin Diu y Kotsesa and Dennis Dayaon y Tupit revolves around the tragic events of October 3, 2003, in Angeles City. Perlie Salvador and her sister Nely were accosted by Welvin Diu, Dennis Dayaon, and Cornelio de la Cruz, Jr. While Diu robbed Perlie, Dayaon and De la Cruz stabbed Nely, leading to her death. Only Diu and Dayaon were apprehended and tried, and the central legal question was whether their participation in the robbery made them equally culpable for the homicide committed by their co-conspirator.

The Regional Trial Court (RTC) found Diu and Dayaon guilty beyond reasonable doubt of robbery with homicide, a decision upheld by the Court of Appeals. The Supreme Court, in its review, emphasized the credibility of Perlie’s testimony as a surviving victim. According to People v. Maxion, appellate courts generally defer to trial courts’ assessments of witness credibility, as they are best positioned to observe demeanor and sincerity. The Supreme Court agreed with the lower courts that Perlie’s account was clear, consistent, and corroborated by the physical evidence of injuries sustained by both sisters.

Both accused-appellants admitted to being at the crime scene. Diu claimed he merely pushed Perlie to protect her from De la Cruz, a narrative the Court found suspicious. Accused-appellant Diu merely walked away from the crime scene the night of October 3, 2003 and made no effort to report what happened to the police or inquire as to Perlie’s condition and even went to Manila for two days. Dayaon’s testimony was riddled with inconsistencies, further undermining his credibility. The Court found it difficult to believe that De la Cruz would so readily and publicly admit to Eduardo that he killed a girl. As well, Esther’s acknowledgment that De la Cruz made no statement that he committed the killing alone, thus, De la Cruz’s admission to the commission of the crime did not necessarily exclude accused-appellants’ participation therein.

The Court addressed the conflicting testimonies regarding the lighting conditions at the scene, ultimately siding with Perlie’s account of well-lit streets that allowed her to clearly identify the perpetrators. The Court agreed that Perlie’s identification of the knife purportedly used in the stabbing of her sister Nely is doubtful. Perlie’s certainty that the knife shown to her at the police station and during trial was the very same knife used in the stabbing of Nely was wholly dependent on the police officer’s representation to her that it was such. However, the Supreme Court clarified that the failure to present the murder weapon is not fatal to the prosecution’s case, as the fact and manner of death were sufficiently proven. According to People v. Fernandez:

Considering the evidence and the arguments presented by the appellant and appellee, the records show that the victim died from multiple stab wounds… It having been established that the victim died from multiple stab wounds, the failure of Mrs. Bates to identify or describe the weapon used is of no consequence and cannot diminish her credibility… The presentation of the murder weapon is not indispensable to the prosecution of an accused… The non-identification or non-presentation of the weapon used is not fatal to the prosecution’s cause where the accused was positively identified.

The Court also dismissed the argument that the investigation initially focused only on homicide, noting that prosecutors have broad discretion to determine charges based on available evidence. In this case, the City Prosecutor of Angeles City, in a valid exercise of his discretion, and after evaluation of the evidence turned over by the police, resolved that there was probable cause to charge accused-appellants and De la Cruz with the crime of Robbery with Homicide, not merely homicide. The Supreme Court extensively cited People v. De Jesus to reiterate the elements of robbery with homicide, emphasizing that the intent to rob must precede the taking of human life:

For the accused to be convicted of the said crime, the prosecution is burdened to prove the confluence of the following elements:

1. the taking of personal property is committed with violence or intimidation against persons;
2. the property taken belongs to another;
3. the taking is animo lucrandi; and
4. by reason of the robbery or on the occasion thereof, homicide is committed.

In robbery with homicide, the original criminal design of the malefactor is to commit robbery, with homicide perpetrated on the occasion or by reason of the robbery. The intent to commit robbery must precede the taking of human life… Once a homicide is committed by or on the occasion of the robbery, the felony committed is robbery with homicide… All those who conspire to commit robbery with homicide are guilty as principals of such crime, although not all profited and gained from the robbery. One who joins a criminal conspiracy adopts the criminal designs of his co-conspirators and can no longer repudiate the conspiracy once it has materialized.

The Court found sufficient evidence of robbery based on Perlie’s testimony, which it deemed credible and consistent. Furthermore, the actions of the accused-appellants and De la Cruz demonstrated a clear conspiracy. Based on Perlie’s testimony, the actuations of accused-appellants and De la Cruz were clearly coordinated and complementary to one another. The absence of proof that accused-appellants attempted to stop Nely’s killing, plus the finding of conspiracy, make accused-appellants liable as principals for the crime of Robbery with Homicide.

The Court also noted that the accused-appellants did not question the legality of their arrests before pleading “not guilty,” thus waiving any objections to the arrest’s validity. Also the Court held that the fatal flaw of an invalid warrantless arrest becomes moot in view of a credible eyewitness account. As stated in Rebellion v. People:

Petitioner’s claim that his warrantless arrest is illegal lacks merit… Any objection involving a warrant of arrest or the procedure by which the court acquired jurisdiction over the person of the accused must be made before he enters his plea; otherwise, the objection is deemed waived… At any rate, the illegal arrest of an accused is not sufficient cause for setting aside a valid judgment rendered upon a sufficient complaint after a trial free from error… It will not even negate the validity of the conviction of the accused.

The Court also modified the damages awarded. The Court ordered accused-appellants to pay Nely’s heirs P50,000.00 as civil indemnity, P50,000.00 as moral damages, and P25,000.00 as temperate damages. Accused-appellants are further ordered to pay Perlie P50,000.00 as moral damages and P1,800.00 as restitution for the cash taken from her. The award for exemplary damages is deleted in view of the absence of any aggravating circumstance.
