When Witnesses Can't See: Proving Robbery With Homicide Through Circumstantial Evidence

In criminal cases, the prosecution must prove guilt beyond reasonable doubt. But what happens when no one actually sees the killing? The Supreme Court's 1999 decision in People v. De la Cruz (G.R. No. 111704) shows that circumstantial evidence—when woven into an unbroken chain—can be enough to convict. This case is a practical guide for understanding how Philippine courts handle robbery with homicide when direct eyewitness testimony to the killing is absent.

The Facts of the Case

On the evening of February 28, 1993, Liza Sebastian, a branch cashier for Andresons Group, Inc., was alone in her office counting the day's remittances. Two armed men barged in and announced a hold-up. One held a bladed weapon; the other had a gun. They demanded money, threatened her life, and took approximately P139,669.00 from the vault.

Before fleeing, the robbers tied Liza's hands with electric cords and covered her head with a jacket. Liza later recognized that jacket as the same one worn earlier that evening by Jaime Fabian, the company's security guard. After freeing herself, Liza ran to the guardhouse and found Fabian dead—shot in the head, with his hands and feet hogtied.

Days later, Liza identified George de la Cruz from police photos and positively identified him in person. De la Cruz was arrested and charged with robbery with homicide under Articles 293 and 294(1) of the Revised Penal Code.

The Defense: Alibi and Inconsistencies

De la Cruz raised two main defenses. First, he claimed alibi—that he was at a cousin's house in Novaliches at the time of the crime. Second, he attacked Liza's credibility, pointing to alleged inconsistencies in her testimony: she said it was her first time seeing him, she could not recall the money's denominations, and she admitted she did not actually see the shooting of the security guard.

The Supreme Court rejected these arguments. The alleged inconsistencies were minor and did not affect Liza's credibility. As the Court noted, minor lapses can even enhance a witness's veracity because they erase suspicion of a rehearsed declaration. More importantly, Liza had ample opportunity to see the appellant's face—he was at arm's length, threatening her with a knife, and the robbers stayed in her office for several minutes.

Why Alibi Failed

The defense of alibi is inherently weak. To succeed, the accused must prove two things: that he was not at the scene of the crime at the time of its commission, and that it was physically impossible for him to be there.

De la Cruz failed on both counts. His own evidence showed it would take only 35 to 40 minutes to travel from his house to the crime scene. Physical impossibility was therefore not established. As the Court held, alibi cannot prevail against positive identification by a credible witness.

The Power of Circumstantial Evidence

The central issue was whether the prosecution proved the homicide element. No witness saw who killed Jaime Fabian. Liza herself admitted she did not witness the shooting.

The Court nevertheless upheld the conviction, relying on circumstantial evidence. Under Section 4, Rule 133 of the Rules of Court, circumstantial evidence is sufficient for conviction when: (1) there is more than one circumstance; (2) the facts from which inferences are derived are proven; and (3) the combination of all circumstances produces a conviction beyond reasonable doubt.

Here, the following circumstances formed an unbroken chain:

• De la Cruz threatened Liza, saying, "Makisama ka sa amin kung ayaw mong mangyari ang nangyari sa gwardiya niyo" (cooperate if you don't want what happened to your guard to happen to you)—showing he knew the guard was already dead or incapacitated.
• The jacket used to cover Liza's head belonged to Fabian, proving the robbers had already disarmed and subdued the guard before entering the cashier's office.
• Fabian was hogtied in the same manner as Liza, showing the same perpetrators were responsible.

Because De la Cruz acted in conspiracy with his companion, the Court ruled there was no need to identify which of them fired the fatal shot. The circumstances established that the robbers disarmed the guard, took his jacket, and killed him before committing the robbery.

Practical Takeaways

• Circumstantial evidence can convict. Philippine courts do not require direct eyewitness testimony when circumstantial evidence forms an unbroken chain pointing to guilt.
• Alibi is a weak defense. It only succeeds when the accused proves physical impossibility of being at the crime scene—not merely being somewhere else.
• Minor inconsistencies do not destroy credibility. Courts give weight to positive identification by a victim who had sufficient time and opportunity to see the accused.
• Conspiracy expands liability. When robbers act together, the prosecution need not prove who specifically committed each act—all conspirators are liable for the natural consequences of the robbery.
• Threats can be powerful evidence. A robber's statement referencing harm to a victim can tie him to that harm, even without direct proof of the act itself.
