G.R. No. 134530 ; December 4, 2000
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. ROBERTO SAMONTAÑEZ y DELA VEGA, accused-appellant.

FACTS

The case involves the rape and killing of 18-year-old Lolita delas Alas. Her body was discovered naked in a sugarcane field in Nasugbu, Batangas, on the evening of November 25, 1995. The prosecution built its case on circumstantial evidence. Witness Carlito Samontañez, a cousin to both the accused and the victim, testified that he saw Roberto Samontañez emerging from the same sugarcane field around 6:30 PM, appearing sweaty, pale, and surprised. Investigation revealed that the victim’s personal belongings were later recovered from Samontañez’s bag at his workplace. Initially pleading not guilty, Samontañez later changed his plea to guilty during pre-trial. The trial court, after conducting a searching inquiry, accepted the plea and, pursuant to the rules, still required the prosecution to present evidence to establish his guilt and the precise degree of culpability.
Following the presentation of evidence, the Regional Trial Court convicted Roberto Samontañez of rape with homicide and sentenced him to death. The case was elevated to the Supreme Court for automatic review, given the imposition of the capital penalty.

ISSUE

The central issue is whether the trial court erred in convicting the accused-appellant based on his plea of guilty and the evidence presented by the prosecution.

RULING

The Supreme Court annulled the trial court’s decision and remanded the case for proper arraignment and trial. The Court found the conviction fundamentally flawed. First, while the trial judge conducted a searching inquiry upon the change of plea, the subsequent proceedings revealed that the plea was not truly informed and intelligent. The defense counsel failed to present any evidence on behalf of the accused after the prosecution rested, and the accused himself later manifested a desire to present evidence and implied he wished to withdraw his guilty plea, claims the trial court did not adequately address. This indicated the accused did not fully comprehend the consequences of his plea.
Second, and more critically, the prosecution’s evidence was insufficient to prove guilt beyond reasonable doubt. The case rested entirely on circumstantial evidence. The Court reiterated the doctrine that for circumstantial evidence to suffice, the combination of circumstances must be consistent with each other, consistent with the hypothesis that the accused is guilty, and inconsistent with any other hypothesis except guilt. The evidence presented—such as the accused being seen near the crime scene and the recovery of the victim’s belongings—did not constitute an unbroken chain leading to the inescapable conclusion that Samontañez was the perpetrator. No witness saw the crime itself, and there was no direct physical evidence conclusively linking him to the rape and murder. Furthermore, the Court noted that the alleged extrajudicial admission by the accused regarding the belongings was obtained without the assistance of counsel, rendering it inadmissible. Consequently, the guilty plea, being improvident, and the prosecution’s evidence, being insufficient, warranted a remand for a full trial on the merits.
