PEOPLE OF THE PHILIPPINES, Plaintiff-Appellee, v. JOSELITO BARTOLOME y GARCIA, Accused-Appellant. G.R. No. 191726 , February 6, 2012.

DOCTRINE: In prosecutions for the illegal sale of dangerous drugs, the identity of the prohibited drug must be established with moral certainty. The chain of custody rule requires that the admission of the *corpus delicti* be proven to have been preserved in its original condition, without alteration, from the time of seizure until its presentation in court. A break in this chain, without a justifiable reason, creates reasonable doubt and warrants acquittal.

FACTS

1. On June 15, 2004, a buy-bust operation was conducted against Joselito Bartolome based on a tip from a confidential informant. PO2 Rodelio Bautista acted as the poseur-buyer.
2. Bartolome allegedly sold one plastic sachet of shabu to PO2 Bautista in exchange for marked money. Upon consummation, the arresting officers apprehended him.
3. The seized sachet was marked by PO2 Bautista at the police station. It was then turned over to the investigator, who prepared a request for laboratory examination. The sachet was delivered to the crime laboratory by a certain PO3 Lagasca, not by the arresting or investigating officers.
4. Forensic Chemist Police Inspector Lourdeliza Cejes confirmed the substance was methamphetamine hydrochloride.
5. The Regional Trial Court convicted Bartolome for violation of Section 5, Article II of Republic Act No. 9165 (Comprehensive Dangerous Drugs Act of 2002). The Court of Appeals affirmed the conviction.
6. Before the Supreme Court, Bartolome argued, among others, that the prosecution failed to establish an unbroken chain of custody of the seized drug.

ISSUE

Did the prosecution successfully establish an unbroken chain of custody of the seized dangerous drug, thereby proving the identity and integrity of the *corpus delicti* beyond reasonable doubt?

RULING

NO. The prosecution failed to establish an unbroken chain of custody, creating reasonable doubt as to the identity of the *corpus delicti*. The accused-appellant is ACQUITTED.

The Supreme Court emphasized that in drug cases, the substance itself is the very *corpus delicti*. Its identity and integrity must be shown to have been preserved. Section 21 of RA 9165, and its implementing rules, outline the chain of custody procedure: immediate physical inventory and photographing in the presence of the accused or his representative, a representative from the media, the Department of Justice, and any elected public official, *all of whom shall be required to sign the copies of the inventory*.

The Court found glaring gaps in the chain:
1. Non-compliance with Witness Requirements: The prosecution did not offer any justifiable reason for the absence of the required witnesses (media, DOJ, elected official) during the inventory. Their presence is crucial to prevent planting, switching, or contamination of evidence.
2. Break in the Custody Trail: After the investigator received the evidence, it was PO3 Lagascaan officer not part of the buy-bust team or the investigationwho delivered it to the forensic chemist. The prosecution failed to account for how PO3 Lagasca received the item, from whom, and its condition upon receipt. This unexplained transfer constituted a significant break in the chain.
3. Failure to Account for Movements: The prosecution did not present testimony or evidence to track the evidence from the investigator to PO3 Lagasca and finally to the chemist. This failure left a gap in the audit trail.

The Court ruled that these lapses, taken together, compromised the integrity of the seized drug. The State’s failure to follow the prescribed safeguards and to explain the deviations raised reasonable doubt about whether the substance presented in court was the same one seized from Bartolome. When the integrity of the *corpus delicti* is compromised, the accused must be acquitted on the ground of reasonable doubt. Joselito Bartolome was ordered immediately released from custody unless held for another lawful cause.
