G.R. No. L-32146 November 23, 1981
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. LUIS DELMENDO y BAL-OT and FLORENTINO DELMENDO, defendants-appellants.

FACTS

The accused-appellants, Luis and Florentino Delmendo, were convicted of murder for the shooting death of Alfredo Buccat in his dwelling on the evening of February 26, 1969. The prosecution’s case rested primarily on the testimonies of the victim’s widow, Magdalena, and son, Elpidio, who identified the appellants as the assailants. They testified that after a prior altercation involving Florentino at the Buccat house earlier that day, both appellants returned in the evening. While the family was eating supper, Luis, positioned at a window, shot Alfredo from a distance of about nine meters. The trial court found the testimonies credible and noted that a paraffin test on Luis was positive for gunpowder nitrates, corroborating his identification as the gunman. The court convicted both, finding conspiracy and treachery, and sentenced them to life imprisonment.
The defense interposed alibi and denial. Crucially, the defense highlighted that both appellants had voluntarily offered to donate blood to the victim after the shooting, with Luis actually donating 250cc. Furthermore, the sworn statements identifying the appellants were executed by Magdalena and Elpidio only on March 14, 1969—16 days after the incident. The defense also presented expert testimony challenging the reliability of the paraffin test, explaining that a positive result could come from handling chemicals other than gunpowder, and a negative result did not conclusively prove one did not fire a gun.

ISSUE

The crucial issue is whether the identities of the appellants as the perpetrators of the crime were proven beyond a reasonable doubt.

RULING

The Supreme Court reversed the conviction and acquitted the appellants. The legal logic centered on the failure of the prosecution to establish guilt beyond a reasonable doubt, primarily due to serious doubts cast on the identification of the accused. The Court meticulously analyzed the evidence and found the delay of 16 days in reporting the identities to the police, without satisfactory explanation, highly suspect and damaging to the witnesses’ credibility. This unreasonably long silence, coupled with the fact that the witnesses did not immediately reveal the assailants’ names to investigating authorities or even to relatives who came to assist right after the shooting, rendered their subsequent identification unreliable.
Furthermore, the Court found the physical circumstances—the nighttime setting, the distance of nine meters, and the witnesses’ vantage point from under the house looking through a small window—made accurate identification in a sudden, violent event difficult. The alleged motive stemming from a trivial daytime quarrel was deemed flimsy and insufficient. The positive paraffin test on Luis was discounted due to the expert testimony on its potential for false positives from contact with other nitrate-containing substances. Most significantly, the appellants’ conduct in voluntarily offering and donating blood to the victim was considered utterly inconsistent with the behavior of guilty perpetrators. Collectively, these factors created reasonable doubt, necessitating acquittal. The prosecution did not overcome the constitutional presumption of innocence.
