G.R. No. 232357 - People vs. Cabezudo y Rieza

The case involves the prosecution of Edwin Cabezudo y Rieza for alleged illegal sale of 0.10 grams of shabu (methamphetamine hydrochloride) in Paracale, Camarines Norte.
Cabezudo was charged under Section 5, Article II of Republic Act No. 9165 (The Comprehensive Dangerous Drugs Act of 2002), as amended.
The trial court (RTC of Daet, Camarines Norte, Branch 39) found him guilty beyond reasonable doubt and imposed a life imprisonment sentence with a fine of Php500,000.

The operation was initiated after a confidential informant alerted the PDEA Camarines Norte Unit at about 9:30 a.m. on August 16, 2011, regarding Cabezudo's involvement in drug trading.
Pre-operation preparations, including the filing of a Pre-Operation Report and coordination with the Regional Office, indicated that the officers had ample time to plan the operation given the informant’s information.
At around 11:00 a.m., the buy-bust team proceeded to Brgy. Palanas where the operation was staged.
At approximately 12:20 p.m., Cabezudo arrived by tricycle; he was approached by a confidential informant who introduced him to a poseur-buyer (SI2 Erwin Magpantay).
A transaction allegedly took place in which Cabezudo handed over a plastic sachet containing a white crystalline substance in exchange for Php500.00, after which he signaled for the arresting officers who subdued and arrested him.

After the arrest, the apprehending team recovered not only the sachet but also additional cash presumed to be proceeds of illegal drug transactions.
The physical inventory and photographing of the seized evidence were carried out; however, discrepancies were noted regarding the attendance of required witnesses (DOJ representative, member of the media, and an elected public official).
Testimonies revealed that during the actual seizure, only a barangay official was present, while the other witnesses were “called-in” later—after leaving the scene—to sign the inventory report at the barangay hall.
This deviation raised concerns regarding the preservation of the integrity of the chain of custody system mandated by Section 21 of RA 9165.

The Prosecution’s version maintained that the buy-bust operation was properly planned and executed, thereby establishing the occurrence of the illegal sale.
The Defense alleged that Cabezudo’s arrest involved elements of a frame-up, describing a scenario where he claimed to have been robbed and apprehended under questionable circumstances, including extraneous actions by SO2 ViaAa.
The discrepancies between the testimonies of the buy-bust team, the barangay official, and Cabezudo led to an extensive discussion regarding the reliability and timing of evidence management.

The investigation focused on whether the apprehending officers complied fully with the procedural requirements under Section 21 of RA 9165.
It was noted that the three required witnesses (from the DOJ, media, and an elected public official) were not present at the time of the actual seizure and inventory.
Despite ample time provided to enforce these requirements, the police officers did not exert sufficient effort to secure the mandated presence of these witnesses at the scene of the arrest.
This lapse in protocol called into question the integrity and evidentiary value of the seized drug, considered by law as the corpus delicti in drug-related offenses.

Whether the trial court and the Court of Appeals erred in convicting Cabezudo given the alleged procedural lapses in the handling of evidence.

Specifically, did the apprehending police officers’ failure to secure the presence of all three required witnesses during the inventory and seizure of the dangerous drug violate Section 21 of RA 9165?
Whether such non-compliance compromised the chain of custody and, consequently, the integrity and evidentiary value of the seized drug.

Whether the presumption of regularity in the performance of police duties can overcome the strong presumption of innocence when there is evidence of deviation from prescribed procedures.

Whether the prosecution fulfilled its burden to prove the elements of the crime—including the corpus delicti and the established chain of custody—beyond reasonable doubt.
