Case Summary (G.R. No. 199133)

Background of the Incident

On August 20, 2009, a confidential informant reported to the Philippine National Police (PNP) about illegal drug transactions by an individual known as “Monik” in Lakeview Homes Subdivision, Muntinlupa City. Following this, the PNP initiated a buy-bust operation, wherein an operative posed as a buyer to facilitate the transaction.

Execution of the Buy-Bust Operation

At approximately 8:15 PM, the operatives executed the buy-bust operation. The poseur-buyer, SPO1 Cirilo Zamora, received a P1,000 buy-bust money marked for identification. The informant communicated with "Monik," who subsequently provided him with a plastic sachet containing a white crystalline substance in exchange for the money. Upon the exchange, the police operatives arrested "Monik," identified as the Appellant, recovering the buy-bust money and the sachet.
