G.R. No. L-6989 November 29, 1955
THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. AGAPITO LINGAD Y SANTOS, LEOCADIO CARREON Y CELSO, AMADO MAMUCOD Y CORTES and CONRADO GRAHAM Y ALEGRIA, defendants-appellants.

FACTS

On the evening of July 18, 1952, a robbery with homicide occurred at the store of Vicente Go on Sulucan Street, Sampaloc, Manila. Two persons initially came to the store to buy items, then returned later with others. During the robbery, money was taken from the store counter at gunpoint, and Vicente Go was shot and killed in an alley beside the store. The perpetrators fled in a taxicab. The police investigation identified the taxicab driver as Amado Mamucod, who confessed and implicated his co-accused Agapito Lingad, Leocadio Carreon, and Conrado Graham, along with Estanislao Real (at large). All four appellants gave confessions detailing their roles. During the trial, store attendants Carlos Go and Amparo Go positively identified Leocadio Carreon and Conrado Graham as the ones who entered the store and took the money, and identified Agapito Lingad as the one who shot Vicente Go. The accused denied participation, raised alibis, and claimed their confessions were extracted by force. The trial court convicted all four as principals of the complex crime of robbery with homicide.

ISSUE

The primary issues are: (1) Whether the accused are guilty of the complex crime of robbery with homicide based on the evidence and their respective participations; and (2) Whether the taxicab driver, Amado Mamucod, should be held liable as a principal or as an accomplice.

RULING

The Supreme Court affirmed the conviction but modified the liability of Amado Mamucod. The Court found the positive identification by witnesses and the detailed, corroborative confessions of the appellants sufficient to establish guilt beyond reasonable doubt, rejecting the defenses of alibi and coerced confessions. However, the Court expressed reasonable doubt that Agapito Lingad was the actual shooter, based on the dark, rainy conditions and the witnesses’ focus on the robbers inside the store, but held this immaterial to his liability. The Court ruled that all conspirators are liable for the complex crime of robbery with homicide under the doctrine established in U.S. vs. Macalalad and People vs. De la Cruz, which holds all principals in the robbery guilty of the homicide committed on the occasion thereof, unless they attempted to prevent it. The conspiracy among Lingad, Carreon, Graham, and Real was conclusively proven by their coordinated acts. Regarding Amado Mamucod, the Court found he was not part of the original conspiracy but furnished the taxicab with knowledge of the criminal design. Therefore, he is liable only as an accomplice, not as a principal. The judgment was affirmed as to Agapito Lingad, Leocadio Carreon, and Conrado Graham as principals. For Amado Mamucod, the judgment was modified, finding him guilty as an accomplice and sentencing him to an indeterminate penalty of 8 years and 1 day of prision mayor as minimum to 14 years, 8 months and 1 day of reclusion temporal as maximum.
