Credibility in Rape and Murder Cases: The Weight of a Witness's Testimony

In People v. Carpo, the Supreme Court upheld a conviction based on one eyewitness, showing how Philippine courts weigh testimony, alibi, and flight.


The outcome of many criminal cases turns on a single question: whom does the court believe? In People v. Carpo (G.R. No. 132676, April 4, 2001), the Supreme Court convicted four men of a grenade attack that killed three members of a family, largely on the testimony of one eyewitness. The ruling offers a clear picture of how Philippine courts assess credibility, treat alibi, and handle compromises over damages.

The facts of the case

On the night of August 25, 1996, a grenade was thrown into the home of the Dulay family in Barangay Baligayan, Pangasinan. Florentino Dulay and his daughters Norwela and Nissan were killed; another daughter, Noemi, was wounded but survived. The explosion itself was never disputed.

What was disputed was who threw the grenade. The prosecution's key witness, Ruben Meriales, testified that he saw barangay captain Jaime Carpo, Warlito Ibao, Oscar Ibao, and Roche Ibao positioned around the area shortly before the blast. He knew all of them personally. Oscar, he said, lifted a wall panel and hurled something inside the hut, then fled toward a nearby creek.

Ruben did not give a statement to the police that night. Fearing retaliation, he promised to come forward after the burial, and did so about a week later.

The issue: one witness against four alibis

The accused attacked Ruben's testimony on two fronts. First, they claimed his sworn affidavit differed from what he said in court. Second, they argued he was biased because he resented the Ibaos over the killing of his brother, Delfin Meriales.

For their part, the accused raised alibi. Jaime Carpo said he was home in a neighboring barangay when the blast occurred. The Ibaos said they were hosting a farewell party for a family member leaving for Hong Kong.

What the Court ruled on credibility

The Court affirmed the conviction. On the alleged inconsistency, it held that Ruben's testimony merely supplied details his affidavit had omitted, and that where an affidavit contradicts testimony in court, the testimony generally commands greater respect. Any such inconsistency, the Court said, would not discredit a fallible witness.

The Court also refused to treat Ruben's admitted resentment as proof of fabrication. His frankness about it, the Court said, should even be counted in his favor. Nor did it find anything unnatural in his hiding behind a kitchen wall instead of warning the Dulays—people react differently to danger, and fear alone does not destroy credibility.

The Court likewise rejected the claim that Ruben had confessed to lying. The only corroborating witness admitted overhearing the supposed conversation from about three meters away while a hut was being built nearby, making the claim unlikely.

Alibi and flight as evidence

Alibi failed. Jaime admitted he was only about 150 meters from the scene and could reach it within thirty minutes. The Ibaos were hosting a party a stone's throw away—yet, the Court noted, they did not come out to investigate after hearing the explosion, unlike their neighbors. Their conduct, the Court said, betrayed them. Their flight to La Union until Roche's arrest further demonstrated guilt and a desire to evade prosecution.

The Court also found conspiracy: the presence of the others gave encouragement and a sense of security to Oscar, who threw the grenade.

Complex crime and the penalty

Because a single act—the explosion—produced three murders and the attempted murder of Noemi, the Court treated the offenses as a complex crime under the Revised Penal Code's provisions on complex crimes, requiring the penalty for the most serious offense to be imposed in its maximum period. Noemi's wounds were not fatal, so the crime against her was attempted, not frustrated, murder. The death penalty was affirmed.

The compromise over damages

One notable portion of the ruling concerns civil liability. During trial, counsel for both sides orally agreed to limit damages to P600,000, and the private complainant signed off on it. The Court set the agreement aside as to the accused. The Court cited Article 1878 of the Civil Code, which requires a special power of attorney to compromise, and the Rules of Court provision on an attorney's authority to bind a client—which likewise requires special authority before a lawyer may compromise a client's litigation. The Court found that the accused had never been consulted and that no special power of attorney had been given, so the settlement could not bind them. The Court instead awarded P50,000 as death indemnity for each of the three deceased, P50,000 as moral damages for each death, and P30,000 as indemnity for Noemi—P330,000 in all.

Practical takeaways

  • A conviction can rest on the testimony of a single eyewitness if the trial court finds that witness credible and straightforward.
  • Minor differences between an affidavit and courtroom testimony do not automatically destroy credibility; testimony in open court is generally given greater weight.
  • Alibi is a weak defense when the accused was physically near the crime scene and could easily have been present.
  • Failure to investigate a loud explosion nearby, and flight after the incident, can be treated as evidence of guilt.
  • A lawyer cannot compromise a client's civil liability without a special power of attorney; any settlement lacking that authority may be set aside.
