G.R. No. 237209 - People vs. Romorosa y Ostoy

Case Summary (G.R. No. 237209)

Factual Background

On February 20, 2010, agents of the National Bureau of Investigation conducted a buy-bust operation in Alabang, Muntinlupa City, following information relayed by a confidential informant about narcotics activity involving an individual known as “Omar.” The operation led to the arrest of the appellant and two male companions later identified as Mohamad and Jamil. The arrest produced several sachets of white crystalline substance later tested positive for methamphetamine hydrochloride.

Charges and Consolidation

Five informations resulted from the operation and were consolidated before the Muntinlupa RTC. The appellant was charged in Criminal Case No. 10-115 with violation of Section 5, Article II of R.A. No. 9165 for the sale of two sachets containing 1.0646 grams and 0.9822 gram of methamphetamine hydrochloride. Mohamad and Jamil faced separate charges for possession and for sale in other consolidated cases.

Prosecution Evidence

The prosecution presented, inter alia, the testimony of Special Investigator Rolan Fernandez as the poseur-buyer and Senior Forensic Chemist Edwin C. Purificando for laboratory analysis. SI Fernandez described the operation: the confidential informant arranged a P 12,000.00 transaction with alias Omar, the buy-bust team positioned itself, SI Fernandez posed as buyer, the appellant handed him two sachets which he purchased with premarked bills, and the team thereafter effected arrests and seizures at the scene.

Arrest, Marking, and Inventory

The buy-bust team exited the scene because a crowd had gathered. SI Fernandez testified that he took immediate custody of the sachets purchased from the appellant, transported them to the NBI Office, and there marked the appellant’s sachets “COR-1a CID-NBI 2-20-2010” and “COR-1b CID-NBI 2-20-2010.” SI Fernandez turned the marked sachets to SI Regalario for inventory, photographs of the appellant with the marked sachets were taken, and the items were submitted to SFC Purificando for laboratory examination.

Forensic Examination and Custody

SFC Purificando examined the marked sachets and testified that the substances tested positive for shabu. He retained custody of the specimens in his personal steel cabinet within his secured office and later personally presented the marked items in court. He described the security features of his cabinet and assured the court that the seals and markings remained intact from his custody until submission to the court.

Defense Case and Appellant’s Account

The appellant testified and denied participation in any sale. She claimed abduction into a vehicle, detention at the NBI, an alleged coaching incident in which SI Fernandez instructed her to point at a sachet for photographs, and a demand for P 500,000.00 by a purported intermediary in exchange for dropping charges. Her narrative constituted the sole defense testimony challenging the prosecution’s version.

Trial Court Findings

The RTC, after trial and consideration of the parties’ evidence, credited the testimonies of SI Fernandez and SFC Purificando and found the appellant guilty beyond reasonable doubt of violating Section 5, Article II of R.A. No. 9165, sentencing her to life imprisonment and a fine of P 500,000.00. The RTC also convicted Mohamad and Jamil of illegal possession in the related possession cases.

Court of Appeals Disposition

The Court of Appeals, in a Decision dated September 25, 2017, affirmed the RTC’s conviction in toto. The CA accepted the trial court’s credibility determinations and the sufficiency of the chain of custody established by the prosecution.

Issues on Appeal to the Supreme Court

The appellant raised two principal contentions: first, that SI Fernandez’s testimony contained an inconsistency regarding whether the confidential informant or SI Fernandez “closed” the P 12,000.00 deal, thereby undermining the credibility of the buy-bust operation; second, that the prosecution failed to prove the corpus delicti and an unbroken chain of custody because SFC Purificando did not forward the examined shabu to an evidence custodian of the NBI but retained and later personally submitted the specimens.

Supreme Court’s Findings on Credibility

The Court found no material inconsistency in SI Fernandez’s testimony. The apparent discrepancy arose from differing uses of the phrase “close a deal” in the Joint Affidavit of Arrest and SI Fernandez’s testimony. The Court accepted the explanation that the confidential informant had arranged the transaction and that SI Fernandez consummated the sale during the buy-bust. The Court observed that the trial court’s assessment of the credibility of law enforcement witnesses with unsullied reputation merited deference, and that the appellant’s bare denial did not overcome the affirmative evidence of the prosecution.

Supreme Court’s Findings on Chain of Custody and Corpus Delicti

The Court applied the four essential links articulated in People v. Kamad, 624 Phil. 289 (2010) for establishing an unbroken chain of custody: seizure and marking by the apprehending officer; turnover to the investigating officer; turnover to the forensic chemist for laboratory examination; and turnover and submission by the forensic chemist to the court. The Court found that the evidence established these links: SI Fernandez seized and marked the sachets, turned them over for inventory, the items were submitted to SFC Purificando who tested positive for methamphetamine hydrochloride, and SFC Purificando retained and later personally produ

Key Factual Allegations

The prosecution alleged that on February 20, 2010, an NBI buy-bust operation in Alabang, Muntinlupa City resulted in the appellant selling two transparent sachets of white crystalline substance to NBI poseur-buyer Special Investigator Rolan Fernandez.
The buy-bust operation followed intelligence from a confidential informant that an alias "Omar" would deliver shabu for a P 12,000 transaction.
During the operation the appellant introduced herself as "Lyn" inside a house on Grabador Street and allegedly handed two sachets to SI Fernandez who gave marked money and signaled the team.
Two male persons later identified as Mohamad and Jamil were arrested inside the house and each was found in possession of one sachet of white crystalline substance.
The seized sachets were marked at the NBI Office by SI Fernandez as COR-1a CID-NBI 2-20-2010 and COR-1b CID-NBI 2-20-2010, inventoried by SI Regalario, photographed with the arrestees, and submitted to Senior Forensic Chemist Edwin C. Purificando for laboratory examination.
Laboratory testing by SFC Purificando confirmed that the sachets were positive for methamphetamine hydrochloride, and ultraviolet examination of the appellant revealed yellow fluorescent smudges on both hands.

Procedural History

Five informations were filed arising from the operation, including Criminal Case Nos. 10-111 through 10-115, which were consolidated for trial.
After the prosecution rested, co-accused Mohamad and Jamil filed a demurrer to evidence without leave which the RTC partially granted as to the sale charges but denied as to possession charges, resulting in their convictions for possession.
Trial continued as to Criminal Case No. 10-115 against the appellant where she testified and denied the charges claiming in flagrante arrest did not occur and alleging a frame-up and extortion demand.
The RTC rendered a Joint Decision convicting the appellant of violation of Section 5, Article II, R.A. No. 9165 and sentencing her to life imprisonment and a fine of P 500,000.00 while convicting Mohamad and Jamil of possession with sentences of twelve years and one day to fourteen years and fines of P 300,000.00 each.
The Court of Appeals affirmed the RTC Decision in its entirety and the appellant appealed to the Supreme Court, which rendered the present decision affirming the CA.

Issues Presented

Whether the RTC and the Court of Appeals erred in crediting the prosecution's version of events as established primarily by the testimony of SI Rolan Fernandez and SFC Edwin C. Purificando.
Whether the alleged inconsistency in SI Fernandez's testimony regarding who arranged the P 12,000 shabu deal materially affected his credibility.
Whether the prosecution proved the corpus delicti beyond reasonable doubt through an unbroken chain of custody given
