Reasonable Doubt Acquittal Despite Presence at Crime Scene

The Supreme Court has repeatedly stressed that in drug cases, the prosecution must prove not only that the accused sold or possessed illegal drugs, but also that the drugs presented in court are exactly the same items seized from the accused. This requirement, known as the chain of custody rule, exists to prevent tampering, substitution, or planting of evidence. In People v. Oliveros (G.R. No. 212202, July 30, 2019), the Court showed how seriously it takes this rule by acquitting an accused even though he was present at the scene of the buy-bust operation.

The Facts of the Case

On November 30, 2007, police officers in Caloocan City conducted a buy-bust operation against Darren Oliveros after receiving information about drug selling in the area. PO1 Malonzo acted as the poseur buyer and allegedly purchased 0.02 gram of shabu from Oliveros for PhP200.00. The police marked the seized sachet as "DOC 11/30/07" and brought it to the crime laboratory, where it tested positive for methylamphetamine hydrochloride.

Oliveros denied the charge. He claimed he was at a billiard hall when seven uniformed policemen arrived, frisked him and his two companions, and brought them to the police station. He alleged that the police demanded PhP10,000.00 from them, and when he could not produce the amount, a case was filed against him.

The Chain of Custody Rule

Section 21 of Republic Act No. 9165 (Comprehensive Dangerous Drugs Act of 2002) requires that after seizure, the apprehending team must immediately conduct a physical inventory and photograph the seized items in the presence of the accused or his representative, a representative from the media, a representative from the Department of Justice, and any elected public official.

The chain of custody has four links: (1) seizure and marking by the apprehending officer; (2) turnover to the investigating officer; (3) turnover to the forensic chemist for laboratory examination; and (4) turnover and submission to the court. Each link must be reliably established to preserve the integrity of the evidence.

The Gaps in the Prosecution's Case

The prosecution proved the first and second links through PO1 Malonzo's testimony. However, the third and fourth links were not reliably established. PO1 Malonzo testified that he handed the seized drug to a certain PO1 Bringuez at the crime laboratory, but he admitted he did not know what PO1 Bringuez did with it afterward. The person who received the drug was not the same person who conducted the laboratory test and testified in court.

The Court also noted other procedural lapses. The buy-bust team did not conduct a physical inventory of the seizure and did not photograph the seized drug in the presence of the required witnesses. No valid justification was offered for these departures from the prescribed procedure.

The Ruling

The Supreme Court reversed the conviction and acquitted Oliveros. The Court ruled that the broken chain of custody created "disturbing uncertainty about the identity and integrity of the seized shabu." Because the prosecution failed to prove beyond reasonable doubt that the drug presented in court was the same item allegedly sold by Oliveros, the case against him collapsed.

The Court emphasized that the accused's presence at the crime scene was not enough. The prosecution must still prove every element of the offense, including the identity of the prohibited drug, through evidence that has not been compromised.

Practical Takeaways

• Chain of custody is mandatory. Police officers must strictly comply with Section 21 of RA 9165, including inventory, photographing, and the presence of required witnesses.
• Every link must be proven. The prosecution must account for the seized drug from the moment of seizure until its presentation in court, including who handled it at each stage.
• Gaps create reasonable doubt. Unjustified departures from the prescribed procedure can result in acquittal, even if the accused was caught in flagrante.
• Presence at the scene is not enough. The prosecution's burden is to prove guilt beyond reasonable doubt, not merely to show that the accused was present.
• For accused persons, the chain of custody is a critical defense area. Defense counsel should scrutinize the prosecution's evidence on this point.
