G.R. No. 227366 , August 1, 2018
DOMINGO AGYAO MACAD @ AGPAD, Petitioner, vs. PEOPLE OF THE PHILIPPINES, Respondent.

FACTS

Petitioner Domingo Agyao Macad was charged with violating Section 5, Article II of R.A. No. 9165 (Comprehensive Dangerous Drugs Act of 2002) for transporting marijuana. The prosecution evidence established that on November 27, 2011, PO1 Davies Falolo, while off-duty, boarded a bus and observed petitioner carrying a carton box and a woven bag. Based on the distinct smell and irregular shape, PO1 Falolo suspected the box contained marijuana. Upon alighting in Bontoc, petitioner hailed a tricycle, which PO1 Falolo also boarded. At a police assistance center, PO1 Falolo called for backup and asked petitioner to open his baggage. Petitioner consented but then fled. He was apprehended, and his baggage was seized and later found to contain bricks of marijuana weighing a total of 16 kilograms.
The defense presented a different version, claiming the carton box belonged to an unidentified companion who had alighted earlier. Petitioner testified he ran upon seeing the police officer out of fear, not guilt, and that he was later coerced into admitting ownership of the drugs. The Regional Trial Court found him guilty, a ruling affirmed by the Court of Appeals. The petitioner appealed to the Supreme Court via certiorari.

ISSUE

The core issue is whether the warrantless arrest of the petitioner and the subsequent seizure of the marijuana bricks were valid, thereby rendering the evidence admissible against him.

RULING

The Supreme Court denied the petition and affirmed the conviction. The legal logic centered on the validity of the warrantless arrest under Rule 113, Section 5(a) of the Rules of Court, which allows an arrest when the person to be arrested has committed, is actually committing, or is attempting to commit an offense in the presence of the arresting officer. The Court held that the arrest was valid as petitioner was caught in flagrante delicto. PO1 Falolo, based on his training and experience, had personal knowledge of facts indicating that an offense was being committed—specifically, the transport of marijuana—due to the box’s distinct odor and peculiar shape observed during the bus ride. Petitioner’s flight upon being questioned at the scene further reinforced the probable cause for his arrest.
Consequently, the search of his baggage was valid as a search incidental to a lawful arrest. The seized items were therefore admissible evidence. The Court also found that the chain of custody of the drugs was sufficiently established, preserving their integrity and evidentiary value. The prosecution successfully proved all elements of illegal transport of dangerous drugs. The defenses of denial and frame-up were rejected for being weak and unsupported by clear and convincing evidence. The penalty of life imprisonment and a fine of Five Hundred Thousand Pesos was upheld.
