G.R. No. 197207 - Marquez y Rayos Del Sol vs. People

On September 28, 2005, reports emerged from concerned parents at Emilio Aguinaldo High School alleging that an employee was selling drugs to students.
Mrs. Elenita Bautista Bagongon, the school guidance counselor, received the reports and presented photographic evidence implicating janitors purportedly paid by the Department of Education, though the identity of the actual culprit was not initially clear.
A student subsequently identified petitioner Benedicto Marquez y Rayos Del Sol, through his photograph, as the drug seller.

At approximately 2:45 p.m. on the same day, Bagongon observed the petitioner with a group of students; as the students dispersed, she noticed him alone holding a piece of paper.
During her approach, the petitioner referred to the paper as “just thrash,” and while attempting to retrieve it, the paper fell to the ground.
Bagongon picked up the paper and discovered two tea bag-like sachets containing dried leaves inside, which she recognized as suspicious.

Bagongon immediately took the sachets to the school principal and the administrative officer, Maria Nancy del Rosario, at the principal’s office.
Acting on instructions from Maria, the school security guard, Virgilio Timonera, was directed to prevent the petitioner from leaving the campus.
The school officials then notified the police, leading to the arrival of SPO2 Joel Sioson and PO3 Edward Acosta.

Upon arrival, the police inspected the items seized from the petitioner and the petitioner was brought to the principal’s office for further questioning.
The petitioner, along with the seized sachets, was taken to the Quezon City Police District Office-Station 8.
Evidence handling details:

PO3 Acosta received the sachets and handed them over to the desk officer.
The desk officer forwarded them to Police Inspector Rex Pascua, who marked the evidence with the identifier EB-B-BMR.
Subsequently, Police Superintendent Julius Caesar Abanes, District Station Commander, personally delivered the evidence along with a laboratory request to the Central Police District Crime Laboratory.
Forensic examination by Engineer Leonard M. Jabonillo confirmed that the sachets contained 1.49 grams of marijuana.

In the Regional Trial Court (RTC), Branch 78, Quezon City, petitioner was found guilty beyond reasonable doubt of illegal possession of marijuana under Section 11, Article II of Republic Act No. 9165.
The RTC sentenced the petitioner to an indeterminate penalty ranging from twelve (12) years and one (1) day to fourteen (14) years and nine (9) months and imposed a fine of P300,000.00.
On appeal, the Court of Appeals (CA) affirmed the RTC decision despite the petitioner’s allegations regarding non-compliance with certain procedural requirements (notably Section 21, Article II of R.A. No. 9165) and purported break in the chain of custody.

The petitioner argued that the police did not strictly comply with the required procedures for handling and custody of the seized drugs.
He contended that the chain of custody over the evidence had been broken.
His motion for reconsideration before the CA was denied via a resolution on June 9, 2011.

Whether the failure of the police to strictly comply with the directives under Section 21, Article II of R.A. No. 9165 rendered the seized evidence inadmissible.
Whether a failure to mark the evidence immediately at the point of seizure compromised the integrity of the chain of custody.

Whether the established chain of custody was sufficiently preserved despite the initial handling by a non-law enforcement personnel (i.e., the guidance counselor).
Whether the subsequent handling and marking by the police maintained the evidentiary value and integrity of the seized marijuana.

Whether all the essential elements for conviction under Section 11, Article II of R.A. No. 9165 were properly and satisfactorily established by the prosecution.
Whether the testimonies of the prosecution witnesses, including that of Bagongon, were credible and free from any improper motive.
