People vs. Callao

The testimony of a single witness, if found positive, credible, and delivered spontaneously and straightforwardly, is sufficient to support a conviction without corroboration; moreover, where conspiracy is established, all conspirators are liable as co-principals regardless of the extent of their individual participation because in contemplation of law, the act of one is the act of all, rendering the defense of impossible crime legally untenable.

On July 15, 2006, Hesson Callao, Junello Amad, Sario Joaquin, and Remmy Casello were at the flea market in Guincalaban, Tayasan, Negros Oriental. Hesson and Junello discussed a plan to kill Fernando Adlawan pursuant to orders from Enrile Yosores. That evening, the group proceeded to Fernando's house where they executed a coordinated attack: Junello struck Fernando on the nape with firewood, hacked him with a bolo, and Hesson stabbed him twice in the chest, extracted his heart, and together with Junello who extracted the liver, fed the organs to a pig before dismembering the body. Sario Joaquin witnessed the entire incident under duress, having been threatened with death if he separated from the group or revealed the crime.

• On July 15, 2006, at the flea market in Guincalaban, Tayasan, Negros Oriental, Hesson Callao and Junello Amad conspired to kill Fernando Adlawan pursuant to orders from Enrile Yosores, while Sario Joaquin and Remmy Casello were present but not part of the planning.
• Sario Joaquin was compelled to accompany the group to the victim's house under threat of death from Hesson if he separated from them.
• At approximately 8:00 PM, the group arrived at Fernando's house where Junello asked for a cigarette lighter; when Fernando handed it over, Junello struck him on the nape with firewood and hacked him on the side with a bolo, causing Fernando to lose consciousness and fall motionless.
• While Fernando lay on the ground, Hesson stabbed him twice in the chest using a knife, sliced open his chest, and extracted his heart; Junello subsequently extracted the liver using a bolo, and both organs were fed to a nearby pig.
• The accused proceeded to cut the victim's neck and slice his body into pieces before leaving the scene; Sario and Remmy followed without intervening due to fear for their lives.
• Sario delayed reporting the incident due to death threats from Hesson and Junello; Remmy was subsequently killed by Enrile during the town fiesta.
• The defense presented Hesson's testimony denying participation, claiming he was cooking inside the house when he saw Junello and Enrile attack Fernando, prompting him to jump out the window and hide in a bushy area until morning.
• Hesson admitted knowing Sario and Remmy but denied Sario's presence at the scene; his testimony contained inconsistencies regarding when he fled his home (initially stating one day after, later stating six months after).
• The death certificate indicated the immediate cause of death as internal hemorrhage and the underlying cause as multiple stab wounds.

• The trial court gravely erred in convicting the accused based solely on the uncorroborated testimony of Sario Joaquin, arguing that a single witness without corroboration is insufficient to establish guilt beyond reasonable doubt.
• The trial court gravely erred in finding conspiracy to commit murder without proving the elements thereof beyond reasonable doubt, contending that mere presence and association do not establish conspiracy.
• The trial court inadvertently erred in failing to rule that the crime committed was an impossible crime, arguing that Hesson could not be liable for murder because it was legally impossible for him to kill Fernando as the latter was already dead when Hesson stabbed him.

• The testimony of Sario Joaquin, as the lone prosecution witness, was sufficient to establish guilt as it was delivered in a straightforward, spontaneous, and categorical manner with no showing of improper motive to falsely impute the crime.
• Conspiracy was sufficiently established by the coordinated acts of Hesson and Junello: they planned the killing together, proceeded to the victim's house together, executed the attack in concert, and jointly mutilated the body by extracting organs and feeding them to a pig, demonstrating unity of action and purpose.
• The defense of impossible crime is unavailing because (1) the victim was not medically established to be dead prior to Hesson's stabbing (Sario's lay opinion was merely an estimation made under stressful circumstances), and (2) the existence of conspiracy makes all conspirators liable as co-principals regardless of who delivered the fatal blow, rendering the "impossibility" defense legally irrelevant.

• Procedural Issues: N/A
• Substantive Issues:
  • Whether a conviction for murder may be sustained based solely on the uncorroborated testimony of a single eyewitness
  • Whether conspiracy between Hesson and Junello was sufficiently proven beyond reasonable doubt
  • Whether the defense of impossible crime should apply to absolve Hesson of liability for murder

• Procedural: N/A
• Substantive:
  • The Court affirmed that the testimony of a single witness, if found positive and credible by the trial court, is sufficient to support a conviction, provided it bears the earmarks of truth and sincerity; corroboration is only required when there are reasons to suspect the witness falsified the truth or was inaccurate in observation.
  • The Court held that conspiracy was sufficiently proven by the acts of Hesson and Junello before, during, and after the crime—specifically their joint planning, coordinated attack, and mutual participation in mutilating the body—which demonstrated unity of criminal design and purpose; once conspiracy is established, all conspirators are liable as co-principals and the court will not speculate on the extent of individual participation.
  • The Court rejected the defense of impossible crime, ruling that legal impossibility (killing a person already dead) was not established because Sario's lay opinion that the victim was dead was insufficient medical proof, and more importantly, conspiracy renders the defense moot as the act of one conspirator is deemed the act of all.
  • The Court affirmed the presence of treachery as the attack was sudden, the victim was unarmed and caught off guard, and the means employed gave him no opportunity to defend himself or retaliate.
  • The penalty of reclusion perpetua was affirmed, as were the awards of civil indemnity (P75,000), moral damages (P75,000), exemplary damages (P30,000), and funeral expenses (P15,000), all earning six percent interest per annum from finality until fully paid.

• Sufficiency of Single Witness Testimony — The testimony of a lone eyewitness, if found positive and credible by the trial court, is sufficient to support a conviction especially when the testimony bears the earmarks of truth and sincerity and had been delivered spontaneously, naturally and in a straightforward manner; witnesses are to be weighed, not numbered, and evidence is assessed in terms of quality and not quantity.
• Conspiracy and Collective Liability — Conspiracy exists when two or more persons come to an agreement concerning the commission of a felony and decide to commit it; once an express or implied conspiracy is proved, all of the conspirators are liable as co-principals regardless of the extent and character of their respective active participation because in contemplation of law the act of one is the act of all.
• Impossible Crime (Legal vs. Factual Impossibility) — Under Article 4(2) in relation to Article 59 of the RPC, an impossible crime requires that the accomplishment was inherently impossible or the means employed was inadequate or ineffectual; legal impossibility occurs where the intended acts, even if completed, would not amount to a crime (such as killing a person already dead), while factual impossibility occurs when extraneous circumstances unknown to the actor prevent consummation.
• Treachery — Treachery exists when the offender commits any of the crimes against persons employing means, methods, or forms in the execution thereof which tend directly and specially to insure its execution without risk to himself arising from the defense which the offended party might make; the essence is the sudden and unexpected attack on an unarmed victim without the slightest provocation, depriving the victim of opportunity to defend himself or retaliate.
• Flight as Evidence of Guilt — Flight from the scene of the crime and failure to immediately surrender militate against the claim of innocence since an innocent person will not hesitate to take prompt and necessary action to exonerate himself of the crime imputed to him.

• "Witnesses are to be weighed, not numbered. Evidence is assessed in terms of quality and not quantity."
• "The testimony of a lone eyewitness, if found positive and credible by the trial court, is sufficient to support a conviction especially when the testimony bears the earmarks of truth and sincerity and had been delivered spontaneously, naturally and in a straightforward manner."
• "In contemplation of law the act of one is the act of all."
• "When two or more persons agree or conspire to commit a crime, each is responsible for all the acts of the others, done in furtherance of the agreement or conspiracy."
