G.R. No. 103499 December 29, 1995
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. REY DENIEGA y MACOY and HOYLE DIAZ y URNILLO, defendants-appellants.

FACTS

The case stemmed from the brutal rape and murder of Marlyn Canoy, whose body was found with multiple stab wounds. Appellants Rey Deniega and Hoyle Diaz were arrested based on information that Deniega had a prior relationship with the victim. During custodial investigation, both appellants executed sworn confessions detailing their participation in the crime. Deniega’s statement implicated Diaz and two other unnamed individuals in the rape and killing, while Diaz’s confession admitted to rape but denied involvement in the homicide, instead pointing to Deniega as the principal assailant. These extra-judicial confessions formed the cornerstone of the prosecution’s case for Rape with Homicide.
At trial, both appellants recanted their confessions, alleging they were extracted through torture, including electrocution and water treatment. They claimed they were arrested without warrants and that their statements were not given voluntarily. They sought the assistance of the National Bureau of Investigation, where they executed sworn statements repudiating their earlier admissions. The defense highlighted procedural lapses in the custodial investigation process.

ISSUE

The central issue is whether the extra-judicial confessions of the appellants are admissible as evidence, given the allegations of coercion and the requirements of constitutional rights during custodial investigation.

RULING

The Supreme Court ACQUITTED appellants Rey Deniega and Hoyle Diaz. The Court ruled that the extra-judicial confessions were inadmissible as evidence. The legal logic rests on the stringent constitutional safeguards under Section 12(1), Article III of the 1987 Constitution and jurisprudence. For a confession to be admissible, it must be proven to have been given voluntarily, with the assistance of competent and independent counsel, and after a meaningful and effective warning of constitutional rights.
The Court found the prosecution failed to overcome the presumption that the confessions were involuntary. The testimonies of the assisting lawyers were deemed insufficient to prove valid waiver of rights, as they were not present at the start of the interrogation and failed to ensure the appellants fully understood their rights and the consequences of their statements. Significant inconsistencies and procedural irregularities, such as the lack of a proper waiver and the lawyers’ passive roles, rendered the confessions invalid. Without these confessions, the prosecution’s case collapsed, as there was no other competent evidence to establish the appellants’ guilt beyond reasonable doubt. The Court emphasized that the Constitution demands strict compliance with custodial investigation procedures to protect the rights of the accused.
