Agpad v. People

Summary

This Supreme Court case involves the conviction of Domingo Agyao Macad for transporting 16 kilograms of marijuana in violation of RA 9165. The key issue was whether the warrantless arrest and search were valid. PO1 Falolo, while off-duty on a bus, detected the distinctive marijuana smell from petitioner's baggage and observed irregular shapes. When petitioner fled upon seeing police backup, officers had probable cause for arrest. The Court upheld the conviction, ruling that the totality of circumstances—marijuana smell, irregular baggage shapes, and flight—constituted probable cause for both the warrantless arrest and extensive vehicle search. The Court found substantial compliance with chain of custody requirements despite minor procedural variations, emphasizing that marking at the police station was justified given security concerns. The decision reinforces that probable cause for drug-related warrantless arrests can be established through sensory evidence combined with suspicious behavior, and that strict technical compliance with procedural rules may be relaxed when the integrity of evidence is preserved.
