    • The operation took place near the Mountain State Agricultural College in Benguet.

    • The other team members who testified were P/Pfc. Elmer Mariano, P/Cpl. Eduardo Garcia, P/Pfc. Virgilio Visperas, and P/Sgt. Murphy Bugtong.
    • The prosecution evidence showed the operation began after the team was informed that someone was looking for a buyer of marijuana.
  • Events leading to the alleged sale
    • The team went with an informer in search of the alleged pusher at his residence near the public market in La Trinidad.
    • The informer talked to the prospective seller, who arranged to meet the buyer after lunch.
    • The team returned at two o’clock that afternoon and failed to talk to the suspect.
    • The team tried again at five o’clock in the afternoon.
    • At that time, Garcia met the first accused-appellant, who was introduced as Daniel Mangusan.
    • Mangusan led Garcia and the informer to a vacant lot near the Benguet General Hospital.
    • A few minutes later, Andy Tonis joined them after a brief conversation with Mangusan.
    • After that brief conversation, Tonis went to the Capitol Building.
    • The three then proceeded to a waiting shed in front of the Mountain State Agricultural College.
    • When Tonis returned at about six o’clock, he asked that the sale be made near the Capitol Building.
    • Garcia refused and insisted that the sale be made where they were.
    • Tonis left again and returned after fifteen minutes carrying a plastic bag.
    • Tokwaban then arrived with a straw bag.
    • Tokwaban suggested that the sale be made at the vacant lot.
    • After examining the contents of Tokwaban’s straw bag, Garcia agreed and walked with the sellers to the vacant lot.
  • Pre-arranged signal, apprehension, and confiscation of marijuana
    • On the way to the vacant lot, Garcia placed her hand in her pocket as the pre-arranged signal to other team members.

    • The policemen were able to apprehend the sellers.
    • The two bags were confiscated.
    • The plastic bag was later found to contain 2.7 kilos.
    • The straw bag was later found to contain one kilo.
    • The specimens were subjected to a field test and were found to be marijuana leaves.
    • The incident was narrated by Garcia and corroborated by the other team members.
  • Post-arrest processing and forensic findings
    • The suspects were taken to the Baguio City Police Station for investigation.
    • The forensic chemist, P/Lt. Carlos Figuerroa of the PC Crime Laboratory, affirmed results of thin layer chromatography and doquenis levine tests.
    • The forensic tests showed that the specimens taken from the bags carried by Tonis and Tokwaban were positive for marijuana.
    • The marijuana leaves were produced in court and offered as exhibits.
  • Defense theories and testimony at trial
    • After the prosecution rested, Mangusan filed a demurrer to the evidence, which the RTC denied.
    • The RTC deemed Mangusan to have waived the right to present evidence pursuant to Rule 119, Sec. 15.
    • Tonis and Tokwaban testified that the bags taken from them belonged to one Benny.
    • Tonis and Tokwaban claimed that Benny asked them to carry the bags for him.
    • While walking on the road toward Campo Filipino, they alleged that men in a jeep arrested them.
    • They alleged that Benny escaped.
    • They claimed they were mauled while under detention.
    • They denied conspiring with each other or with Mangusan to commit the crime.
    • Tokwaban pleaded minority, asserting he was less than eighteen years old at the time of the alleged offense.
    • No other defense witnesses were presented.
  • RTC credibility findings on conspiracy and sale
    • The RTC disbelieved the account that “Benny” was the real owner of the marijuana.
    • The RTC held that the facts showed the three accused-appellants were acting in concert.
    • The RTC found that Mangusan negotiated the deal with Garcia.
    • The RTC found that Mangusan then ordered Tonis to get the marijuana.
    • The RTC found that Tonis, in turn, ordered or caused Tokwaban to carry/provide the marijuana.
    • The RTC found that the roles of the three manifested from Mangusan’s offering to sell to Garcia until Tonis and Tokwaban produced the marijuana at Mangusan’s bidding.
    • The RTC reasoned that after the informer approached Mangusan and they agreed to meet later after lunch, Mangusan contacted Tonis and Tokwaban and asked them to make ready the marijuana to be sold that same day.

    • Whether the absence of evidence of money as consideration disproved that a sale of marijuana occurred.
  • Credibility of defense theory and the “Benny” explanation
    • Whether the trial court erred in discrediting the claim that the marijuana belonged to a mysterious person, “Benny,” who allegedly asked the accused-appellants to carry the bags.
  • Consequence of Mangusan’s demurrer to the evidence
