People vs. Umbrero

Conspiracy may be inferred from the collective acts of the accused before, during, and after the commission of a crime, demonstrating a common criminal design. Where armed individuals arrive together at a scene, position themselves around the victim, and depart together after the killing, their concerted actions establish conspiracy, making each liable for the acts of the others.

Alfonso Urbi was shot and killed in his daughter's house in Sta. Teresa, Lallo, Cagayan, on November 29, 1980. The prosecution alleged that a group of armed men, including the appellants Mariano Umbrero, Alfredo Costales, and Jimmy Agluba, arrived at the house. One of them, Danny Costales, asked for water and then shot Urbi. The appellants were identified as companions who were armed and present during the shooting. They were charged with Murder qualified by treachery and with the aggravating circumstances of abuse of superior strength and band.

• Nature of the Action: Criminal prosecution for Murder under Article 248 of the Revised Penal Code.
• The Shooting: On November 29, 1980, at around 2:00 PM, a group of more than ten armed men arrived at the house of Angelina Urbi Ragsac in Sta. Teresa, Lallo, Cagayan, where her father, Alfonso Urbi, was present. Danny Costales asked for water. When Alfonso Urbi approached, Danny Costales shot him. Urbi ran outside but was followed and shot again by Danny Costales, causing his death.
• Identification of Appellants: Prosecution witnesses Angelina Urbi Ragsac (the victim's daughter) and Eugenia Urbi (the victim's spouse) positively identified appellants Mariano Umbrero, Alfredo Costales (Pido), and Jimmy Agluba as among the armed men present at the scene. They testified the appellants were holding firearms, stood near Danny Costales during the shooting, and left together with the group afterward. Witness Martin Pagaduan also identified them as part of the armed group he saw surrounding the house.
• Appellants' Defense: The appellants interposed alibi. Mariano Umbrero claimed he was milling palay elsewhere. Alfredo Costales claimed he was in Aparri for a burial. Jimmy Agluba claimed he was in Newagac, Gattaran. Their alibis were corroborated primarily by their relatives.
• Lower Court Findings: The RTC found the prosecution witnesses credible and their positive identification sufficient to establish conspiracy. It rejected the alibis as weak and not physically impossible.

• Denial of Preliminary Investigation: Appellant Umbrero argued that the Information against him should have been dismissed because no criminal complaint or preliminary investigation was conducted in the municipal court or the provincial prosecutor's office, denying him due process.
• Lack of Conspiracy: The appellants contended that mere presence at the scene does not prove conspiracy. They argued there was no proof of their participation in the killing, and thus they should be acquitted.

• Waiver of Preliminary Investigation: The Solicitor General countered that Umbrero was given the opportunity to file a counter-affidavit during the preliminary investigation. Furthermore, any right to a preliminary investigation was waived when he failed to raise the issue before entering his plea.
• Existence of Conspiracy: The prosecution argued that conspiracy could be inferred from the appellants' acts before, during, and after the crime. Their armed presence, proximity to the principal assailant, failure to prevent the crime, and joint departure demonstrated a common criminal purpose.

• Due Process: Whether appellant Umbrero was denied his right to a preliminary investigation and due process.
• Conspiracy: Whether conspiracy was sufficiently proven to hold the appellants liable for the murder committed by Danny Costales.

• Due Process: The allegation of denial of due process was unmeritorious. The records showed Umbrero was ordered to file a counter-affidavit during the preliminary investigation. Moreover, the right to a preliminary investigation is not a jurisdictional requirement; its absence does not affect the court's jurisdiction. The right is deemed waived if not invoked before or at the time of entering a plea. Umbrero pleaded without raising the issue, thus any irregularity was cured.
• Conspiracy: Conspiracy was established. The appellants' collective actions—arriving armed together, surrounding the victim's house, standing near the shooter, drawing their weapons when the victim fled, and leaving together after the killing—demonstrated a unity of purpose and action. Conspiracy need not be proven by direct evidence but can be inferred from conduct. Their failure to prevent the crime, despite the opportunity, further indicated a common design. Consequently, the act of the principal, Danny Costales, was the act of all.

• Conspiracy — Exists when two or more persons come to an agreement concerning the commission of a felony and decide to commit it. It may be deduced from the mode, method, and manner in which the offense is perpetrated, or from the acts of the accused before, during, and after the commission of the crime pointing to a joint purpose and design. In this case, conspiracy was inferred from the armed group's coordinated arrival, positioning, and departure.
• Treachery (Alevosia) — Present when the offender commits any of the crimes against the person, 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 sudden and unexpected attack on an unarmed and unsuspecting victim constituted treachery.
• Waiver of Preliminary Investigation — The right to a preliminary investigation is statutory, not constitutional. If an accused fails to invoke it before entering a plea, the right is deemed waived, and any defect in the preliminary investigation is cured.

• "The appellants' actuations immediately prior to, during, and right after the shooting of Alfonso Urbi indicate their common intention to commit the crime. The appellants were not merely present at the scene of the crime." — This passage underscores that active, coordinated presence and conduct, not mere passive presence, establishes conspiracy.
• "The defense of alibi cannot prevail over the positive identification by the prosecution witnesses of the appellants." — A standard principle reaffirming the weakness of alibi against credible positive identification.

• People v. Casiano, 1 SCRA 478 (1961) — Cited for the rule that the absence of a preliminary investigation does not affect the court's jurisdiction and the right is waived if not timely invoked.
• People v. de Guzman, 162 SCRA 145 (1988) — Cited for the principle that in conspiracy, the act of one is the act of all.
• People v. Cempron, G.R. No. 66324 (1990) — Cited for the definition of treachery.

• Article 248, Revised Penal Code — Defines and penalizes the crime of Murder.
• Article 8, Revised Penal Code — Defines conspiracy.
