G.R. No. 1902 - People vs Isais

The case involves a complaint filed on October 2, 1903, against five defendants: Ludovico Isais, Tranquilino Caguiat, Basilio Tolentino, Romualdo Lopez, and Alejandro Yutoc, who were charged with the crime of frustrated murder.
The provincial fiscal of Tarlac alleged that the defendants conspired to poison nine Constabulary soldiers by administering a lethal dose of poison, but death did not occur due to timely remedial measures.

On the evening of July 2, 1903, between 6 and 7 o’clock, Sergeant Jose Casado, along with ten soldiers patrolling the barrio, arrived at the barracks in the barrio of San Miguel, Concepcion, Tarlac.
Lieutenant Ludovico Isais, on the request of the first sergeant, along with his accomplices Tranquilino Caguiat and Basilio Tolentino, served food and water to the soldiers.
The meal was prepared by Mariano Arceo and delivered by Caguiat, while the water was brought in a vessel delivered by Tolentino to Lieutenant Isais at the steps of the barracks.

Within seven minutes after partaking of the meal, the nine soldiers who remained in the barracks began exhibiting symptoms: swollen tongues, loss of consciousness, and severe illness.
Sergeant Casado and Private Agapito Suarez, who had eaten elsewhere, observed that the remaining nine soldiers were progressively falling ill.
Prompt action was taken by placing the ailing soldiers in carts and transporting them to the town, where the municipal president and the president of the board of health provided immediate medical assistance.

The evidence presented indicated that the water, not the food, was the vector of poisoning, as the liquid contained a lethal dose of tarampuna y, known to cause intestinal inflammation, delirium, muscle disorder, and eventually death.
Medical evidence consisted of testimonies by physicians Prudencio Hernandez, Hugo Van Shuster, and Don Andres Catanhal, who confirmed that the quantity of poison was sufficient to cause death had it not been for the timely intervention.
The recovery of the soldiers following the administration of antidote medicine, which induced vomiting, corroborated the assertion of poisoning.

Lieutenant Ludovico Isais was implicated as the principal actor, having direct responsibility for administering the poison and having received instructions from Felipe Salvador, the chief of the association known as "Santa Iglesia."
Evidence showed that Isais was acquainted with Salvador and had traveled to the camp, receiving orders to poison the soldiers in order to facilitate the seizure of their firearms.
Testimonies from witnesses, including Fausto Cordero and Basilio Tolentino, outlined the plan and the execution, noting that Isais ordered Tolentino to dispose of the remaining poisoned water after delivering it.
In contrast, Tranquilino Caguiat, responsible for conveying the meal, and Basilio Tolentino, who delivered the water and later disposed of the residual, showed insufficient evidence linking them directly to the intended poisoning beyond their logistical roles.

The lower court initially sentenced Isais to fourteen years and eight months of cadena temporal with additional penalties, and Caguiat and Tolentino to thirteen years each, along with the costs.
However, upon reviewing the evidence, it was determined that while Isais’s actions clearly constituted a commenced execution of the crime, the participation of Caguiat was not sufficiently proven, and Tolentino’s involvement was negated by his subsequent death in prison.

Whether the evidence is sufficient to establish that Lieutenant Ludovico Isais committed the crime of frustrated murder by administering a lethal poison with the intent to kill.
Whether the overt acts and the affiliation with the criminal organization “Santa Iglesia” are enough to attribute criminal intent and premeditation to Isais.

Whether Tranquilino Caguiat’s role in delivering the meal, despite initial suspicion, constitutes criminal participation in the poisoning.
Whether Basilio Tolentino’s involvement in delivering the water and the act of disposing of the remainder cumulatively satisfy the elements of participation, notwithstanding his death during detention.

Whether the failure to cause death due to prompt medical intervention negates the criminal liability for the crime of frustrated murder.
The extent to which the direct overt act of poisoning constitutes “a beginning in the execution” of the crime, despite non-fulfillment of the final intended result (i.e., death).
