Case Summary (G.R. No. 38434)

Factual Background

On the night of February 12, 1932, house No. 1155 F. B. Harrison Street, Pasay, the dwelling of James C. Rockwell, was entered by breaking a window and two watches valued at P320 were taken from Mrs. Rockwell’s bedroom. A small silver box taken from the room was found the next morning in the garden and bore a fingerprint on its top. The defendant admitted that the house was robbed and that the silver box was recovered and examined by the Intelligence Division of the Constabulary, but he denied being the offender.

Investigation and Custody

While investigating the robbery, Agripino Ruiz, a Constabulary agent and fingerprint expert, encountered the accused while the latter was under arrest for a separate breaking into the house of Capt. Davidson in Paranaque. Ruiz took the defendant’s fingerprints and compared a photograph of the impression of the middle finger of the defendant’s right hand with a photograph of the fingerprint on the top of the silver box.

Expert Fingerprint Testimony

Agent Agripino Ruiz testified that the two photographs coincided in ten points and that in his opinion the impressions were from the same person. He explained that the ten agreed points involved endings of ridges, bifurcations, short ridges, and the core. He stated his belief that eight characteristics were sufficient to identify a person and placed reliance on accepted authorities on fingerprint identification. Photographs marked at trial as Exhibits A, A-1, and A-2 showed enlargements of the box impression; Exhibit B was an enlargement of the photograph of the defendant’s middle-finger impression taken while the defendant was a prisoner in Bilibid. The household members’ fingerprints were taken and did not correspond to the impression on the box.

Defense and Alibi

The defendant offered an alibi, testifying that he was at home in San Luis, Batangas, on the night of the robbery with a sore foot. The alibi testimony was uncorroborated. The defendant admitted the competency of Agripino Ruiz as an expert and admitted three prior theft convictions relied upon by the prosecution to establish habitual delinquency.

Legal Issues Presented

The appeal challenged (one) the identification by fingerprint evidence as unreliable because only one, partially blurred, accidental imprint appeared on the box; (two) the sufficiency of proof that the appellant took the silver box and the watches from Mrs. Rockwell’s room; and (three) the appellant’s conviction for robbery in an inhabited house and the penalties imposed, including the additional penalty for recidivism.

Applicable Law on Fingerprint Evidence

The Court reviewed authority recognizing that fingerprint correspondence is admissible to prove identity, citing Moon vs. State, People vs. Sallow, and Castleton's Case, and relied upon accepted scientific writings to explain the permanence and individuality of papillary ridges and Galton’s minutiae. The Court observed that although older authorities sometimes required twelve points of correspondence, more recent authorities accept six or eight homologous points as leaving no reasonable doubt.

Trial Court Findings and Sentence

The trial court found the defendant guilty of robbery in an inhabited house and of being a habitual delinquent. It sentenced the defendant to a principal penalty of ten years and one day of prision mayor and imposed an additional penalty of ten years of prision mayor for recidivism. The court ordered indemnification to James C. Rockwell in the sum of P320 and the payment of costs.

Supreme Court’s Analysis of Identification Evidence

The Supreme Court found little merit in the contention that a single, partially blurred fingerprint was insufficient. The Court observed that accidental imprints are often imperfect but that the decisive question was whether the evidence identified the accused beyond a reasonable doubt. The Court accepted Agripino Ruiz’s testimony that ten homologous points matched and noted that the expert explained the characteristics compared. The Court remarked that the prosecutor should have examined the expert more fully on his method and that the prosecution might have produced another expert, but concluded that no reason existed to reject the expert’s findings. The Court also noted that an additional blurred partial impression on the box remained unidentified and might have been made by the person who picked up the box in the garden; that fact did not negate the identification by the clearer impression.

Assessment of the Alibi and Weight of Prior Convictions

The Court considered the defendant’s uncorroborated alibi inadequate to rebut the identification evidence. The Court further held that it was proper to take into account the defendant’s admitted three prior convictions for theft in assessing the credibility of his testimony.

Legal Classification of the Offense and Penalty Framework

The Court analyzed article 299 of the Revised Penal Code. It stated that robbery in an inhabited house is punishable by prision mayor in its medium period to reclusion temporal in its minimum period when the value exceeds P250 and the offender entered by breaking a window. However, where the offe
