In People v. Enriquez, the Supreme Court acquitted the accused due to the prosecution’s failure to establish an unbroken chain of custody for the seized drugs. This ruling underscores the critical importance of meticulously preserving the integrity and evidentiary value of drug evidence from the moment of seizure to its presentation in court. This case serves as a reminder that strict adherence to procedural safeguards is essential to protect the rights of the accused and maintain the integrity of the justice system.

Failing the Chain: How a Buy-Bust Led to an Acquittal

The case revolves around Arturo Enriquez, who was charged with violating Sections 5 and 11, Article II of Republic Act No. 9165, also known as the “Comprehensive Dangerous Drugs Act of 2002.” These charges stemmed from a buy-bust operation conducted by police officers in Porac, Pampanga, where Enriquez was allegedly caught selling and possessing shabu (methamphetamine hydrochloride). The prosecution presented evidence including confiscated sachets of shabu and the testimony of the arresting officers. However, the defense argued that the police officers failed to comply with the proper procedures for handling seized dangerous drugs, particularly concerning the chain of custody. This raised serious questions about the integrity and identity of the evidence presented against Enriquez.

The Supreme Court meticulously examined the records and found significant gaps in the prosecution’s evidence regarding the chain of custody. The **chain of custody** refers to the duly recorded authorized movements and custody of seized drugs or controlled chemicals at each stage, from the time of seizure/confiscation to receipt in the forensic laboratory, to safekeeping, to presentation in court for destruction. This ensures that the evidence presented in court is the same substance that was seized from the accused, preventing any tampering or substitution.

The Court emphasized that in cases involving dangerous drugs, the drug itself constitutes the very corpus delicti of the offense. Therefore, its identity and integrity must be proven beyond a reasonable doubt. This necessitates a clear and unbroken chain of custody, which, according to Section 21, Article II of Republic Act No. 9165, involves several crucial steps:

Section 21. Custody and Disposition of Confiscated, Seized, and/or Surrendered Dangerous Drugs, Plant Sources of Dangerous Drugs, Controlled Precursors and Essential Chemicals, Instruments/Paraphernalia and/or Laboratory Equipment. – The PDEA shall take charge and have custody of all dangerous drugs, plant sources of dangerous drugs, controlled precursors and essential chemicals, as well as instruments/paraphernalia and/or laboratory equipment so confiscated, seized and/or surrendered, for proper disposition in the following manner:

(1) The apprehending team having initial custody and control of the drugs shall, immediately after seizure and confiscation, physically inventory and photograph the same in the presence of the accused or the person/s from whom such items were confiscated and/or seized, or his/her representative or counsel, a representative from the media and the Department of Justice (DOJ), and any elected public official who shall be required to sign the copies of the inventory and be given a copy thereof[.]

The Implementing Rules and Regulations further elaborate that the physical inventory and photograph shall be conducted at the place where the search warrant is served, or at the nearest police station or office of the apprehending team in case of warrantless seizures. However, the Supreme Court noted that in this case, the prosecution failed to establish several critical links in the chain of custody.

The first crucial link is the seizure and marking of the illegal drug immediately after it is recovered from the accused. The marking serves as the starting point for identifying the evidence throughout the custodial chain. In People v. Zakaria, the Supreme Court stressed the importance of this step, stating:

Crucial in proving the chain of custody is the marking of the seized dangerous drugs or other related items immediately after they are seized from the accused, for the marking upon seizure is the starting point in the custodial link that succeeding handlers of the evidence will use as reference point. Moreover, the value of marking of the evidence is to separate the marked evidence from the corpus of all other similar or related evidence from the time of seizure from the accused until disposition at the end of criminal proceedings, obviating switching, “planting” or contamination of evidence. A failure to mark at the time of taking of initial custody imperils the integrity of the chain of custody that the law requires.

Although the items presented in court bore the initials of SPO2 David, the poseur-buyer, there was no evidence to show when these items were actually marked and whether they were marked in the presence of Enriquez or his representative. This omission raised doubts about the authenticity and integrity of the evidence.

The second link involves the turnover of the illegal drug from the apprehending officer to the investigating officer. While SPO2 David and SPO2 Divina testified that they brought Enriquez and the seized items to the police station, they failed to identify the person to whom they turned over the evidence. The request for laboratory examination was prepared by Chief of Police Erese, but there was no evidence showing that he was the one who received the items from the apprehending officers. This created a critical missing link in the chain of custody.

The third and final links relate to the handling of the evidence after it reached the investigating officer and during its examination by the forensic chemist. Although Chief of Police Erese signed the request for laboratory examination, he was not presented in court to testify. This was significant because his testimony could have bridged the gap between the testimony of SPO2 David and the stipulated testimony of P/Insp. Dizon, the forensic chemical officer. Furthermore, there was no testimony regarding how the confiscated items were handled and cared for after the laboratory examination. This lack of accountability created a further break in the chain of custody.

The Supreme Court noted that the prosecution failed to present the testimonies of all individuals who handled the specimen. This is a critical requirement for establishing an unbroken chain of custody. Of all the individuals who came into direct contact with the shabu allegedly seized from Enriquez, only SPO2 David testified, and his testimony ended with his identification of the marked money and seized items at the police station. This left significant gaps in the custodial chain.

In light of these deficiencies, the Supreme Court concluded that the prosecution failed to prove Enriquez’s guilt beyond a reasonable doubt. The Court emphasized that the failure to establish the evidence’s chain of custody is fatal to the prosecution’s case. Without a clear and unbroken chain, the integrity and evidentiary value of the confiscated dangerous drug cannot be safely assumed.

The Court reiterated the fundamental principle that an accused is presumed innocent until proven guilty beyond a reasonable doubt. Because the prosecution failed to meet this burden, Enriquez was acquitted.
