G.R. No. 65647 - People vs. Flores

The People of the Philippines charged Ernesto Flores for allegedly selling marijuana in violation of Republic Act No. 6425, as amended (the Dangerous Drugs Act).
The alleged transaction involved the sale and delivery of fifteen (15) dried marijuana stalks in exchange for a total of P10.00 along E. de los Santos Avenue, Balintawak, Quezon City.
The incident reportedly occurred on or about August 21, 1980.

Canu (Constabulary Anti-Narcotics Unit) officers conducted a “test-buy” operation the day before the arrest, followed by a “buy-bust” operation to apprehend the accused.
Witness Sgt. Angel Nieves, along with CIC Godofredo Fider and Pfc. Wilfredo Tamondong, testified that during the operation, the accused handed over the marijuana stalks to a confidential informer acting as a buyer-poseur (Annalisa Santos).
The physical evidence included two five-peso bills (one allegedly marked) and the fifteen marijuana stalks, which were subsequently confirmed as marijuana via forensic examination by the NBI.

Ernesto Flores claimed he was engaged in his usual routine activities — working as a painter in the morning and later buying viand from a local store.
He alleged that, without warning, he was accosted by unknown individuals who fired a gun at him and then forcibly placed a plastic packet (purportedly containing contraband) in his hip pocket.
He was then coerced into boarding a vehicle, taken to the CANU headquarters in Malabon, where he was frisked, beaten, tortured, and made to sign a written confession.
Flores contended that the confession was extrajudicial and obtained without full and meaningful communication or explanation of his constitutional rights.

At trial, the Regional Trial Court of Quezon City (Branch 87) found Flores guilty beyond reasonable doubt of selling marijuana, sentencing him to life imprisonment, a fine of P20,000, and the payment of costs.
The trial court heavily relied on the testimony of Sgt. Angel Nieves, notwithstanding material discrepancies in his accounts, particularly regarding the exact time of the arrest (varying between 12:10 p.m., 8:30 p.m., and 9:30 p.m.).
The prosecution’s case was further weakened by the absence of the alleged buyer-poseur, Annalisa Santos, who did not testify or appear in court.

Whether the confession obtained from Ernesto Flores during custodial interrogation was admissible, given that it was obtained without a proper explanation of his rights or without an express waiver in an understandable manner.

Whether the totality of the evidence, particularly the inconsistent testimony of Sgt. Angel Nieves and the absence of direct testimony from the buyer-poseur, establishes the guilt of Ernesto Flores beyond reasonable doubt.

Whether the inconsistencies in the key eyewitness’s (Sgt. Nieves’s) testimony regarding critical details of the apprehension (notably the time of arrest) undermine the prosecution’s case and hence, the conviction.
