Facts:

Appellant Ronaldo de Guzman y Danzil was charged with Illegal Sale of Dangerous Drugs under R.A. No. 9165 in Criminal Case No. V-1118 before the Regional Trial Court (RTC) of Villasis, Pangasinan.

The Supreme Court reviewed the trial record and the testimony of police witnesses (including SPO1 Llanillo and SPO3 Yadao), noting admissions that marking occurred only at the police station, no proper inventory or photographs were shown, and that a multi-hour lapse occurred before the investigating officer recorded the incident and placed initials on exhibits.
