In illegal drug cases, the prosecution must prove the identity and integrity of the seized drugs beyond reasonable doubt. The Supreme Court held that the failure of police officers to immediately mark seized drugs and a vague recollection of the transfer of custody creates a significant gap in the chain of custody. This jeopardizes the integrity of the evidence, leading to reasonable doubt and ultimately, acquittal. The prosecution’s failure to conclusively establish the crucial link in the chain of custody resulted in the appellant’s acquittal due to reasonable doubt.

Unraveling the Chain: When Doubt Leads to Acquittal in Drug Possession

This case, People of the Philippines v. Alberto Bacus Alcuizar, revolves around an appeal challenging the conviction of Alberto Bacus Alcuizar for illegal possession of dangerous drugs, specifically shabu, a violation of Section 11, Article II of Republic Act No. 9165. The core legal question is whether the prosecution successfully established beyond reasonable doubt that the seized drugs presented in court were indeed the same drugs recovered from the appellant, thus ensuring the integrity of the corpus delicti, the body of the crime. The appellant argued that the chain of custody was unreliable and that his conviction violated his constitutional right against double jeopardy.

At the heart of drug-related prosecutions lies the concept of the chain of custody. This principle demands meticulous tracking of evidence from the moment of seizure to its presentation in court. It ensures that the drugs presented are the exact same ones confiscated, untainted by tampering or substitution. The Supreme Court emphasized the critical role of the chain of custody rule, requiring that “the marking of the seized items should be done in the presence of the apprehended violator and immediately upon confiscation to ensure that they are the same items that enter the chain and are eventually the ones offered in evidence.”

In this case, the police officers, armed with a search warrant, searched the house of Alberto Bacus Alcuizar. They allegedly found several packets of shabu. A key issue arose because SPO1 Agadier, the police officer, admitted that he only marked the seized items at the police station, not immediately after confiscation. The Court pointed out that immediate marking is crucial, especially when a search warrant is involved. The failure to mark the evidence immediately created a first gap in the chain of custody, casting doubt on whether the drugs presented in court were the exact same ones seized from Alcuizar’s residence.

Section 21 of Republic Act No. 9165 outlines specific procedures for handling seized drugs, including inventory and photographing in the presence of the accused, media, and a representative from the Department of Justice (DOJ). The law mandates that these individuals sign the inventory and receive a copy. The Supreme Court has consistently stressed the importance of adhering to these guidelines to maintain the integrity of the evidence. In this case, the police officers also failed to provide Alcuizar with a copy of the inventory receipt. Although this omission alone is not necessarily fatal, it contributed to the overall doubt surrounding the handling of the evidence.

The testimony of a barangay tanod (village watchman) further complicated matters. He admitted arriving at Alcuizar’s house after the police officers and found the alleged shabu already on a table. The barangay tanod stated he was merely asked to sign the inventory receipt without witnessing the search or the discovery of the drugs. This raised serious questions about the authenticity of the inventory and the circumstances surrounding the seizure of the drugs. The court weighed the barangay tanod’s testimony heavily because he was an unbiased witness.

Adding to the prosecution’s woes, SPO1 Agadier’s testimony regarding the transfer of custody of the shabu was vague. He failed to specify who had initial control and custody of the drugs immediately after confiscation and how the drugs were handled in transit. SPO1 Navales, who allegedly received the drugs from SPO1 Agadier, did not testify to corroborate Agadier’s statements. This lack of clarity created a second significant gap in the chain of custody, making it difficult to ascertain whether the drugs submitted to the crime laboratory were indeed the same ones seized from Alcuizar’s house.

The Supreme Court reiterated the elements necessary to successfully prosecute a case of illegal possession of dangerous drugs: (1) the accused is in possession of an item identified as a prohibited drug; (2) such possession is unauthorized by law; and (3) the accused freely and consciously possessed the drug. Due to the gaps in the chain of custody and the lack of credible evidence, the Court entertained serious doubts about whether the drugs were actually found in Alcuizar’s house. This reasonable doubt compelled the Court to acquit Alcuizar, as the prosecution failed to prove his guilt beyond a reasonable doubt. The Court in People v. Garcia enumerated cases dealing with failure to comply with Section 21 of Republic Act No. 9165.

In People v. Orteza, the Court, in discussing the implications of the failure to comply with Paragraph 1, Section 21, Article II of R.A. No. 9165, declared:

In People v. Laxa, where the buy-bust team failed to mark the confiscated marijuana immediately after the apprehension of the accused, the Court held that the deviation from the standard procedure in anti-narcotics operations produced doubts as to the origins of the marijuana. Consequently, the Court concluded that the prosecution failed to establish the identity of the corpus delicti.
