G.R. No. L-5985
THE UNITED STATES, plaintiff-appellee, vs. JUAN IDICA and SILVESTRE YADAO, defendants-appellants.
November 17, 1910

FACTS:
Tecla Llana, a 22-year-old unmarried girl, was engaged to Gelasio Lacuesta with their wedding scheduled for May 24, 1909. On the morning of May 23, 1909, she left her brother Venancio Llana’s house to go to town for confession. Venancio told her it was too early and she should return home and wait. Tecla returned towards her house but was never seen alive again. Later that afternoon, her body was discovered in a small wood, about 30 meters from her house. She had a fractured skull, broken upper teeth, and a blood-stained piece of a broken club was found beside her. The justice of the peace identified the club piece as belonging to Juan Idica, who had confirmed it during the preliminary investigation, and family members suspected Idica.

Evidence presented against Silvestre Yadao included:
1. Venancio Llana’s testimony that Tecla prevented him from waking Yadao on May 22, stating Yadao “did not have good intentions toward her,” and that Venancio saw Yadao holding a stick.
2. Cesarea Calaycay’s corroboration of Venancio’s testimony about the stick.
3. David Marquez’s testimony that he saw both Idica and Yadao running through a garden near Tecla’s house on the morning of May 22.
4. Guillermo Rañeses and Luis Idica’s testimony that Yadao confessed to them that he committed the homicide because Tecla broke an agreement not to marry without his consent.

Evidence presented against Juan Idica included:
1. Venancio Llana’s testimony that on May 21, Idica attempted to enter Tecla’s room while she was asleep.
2. Venancio Llana’s testimony that on May 22, Idica threatened that if Tecla married someone else, he “would not regret killing her,” and expressed regret over her impending marriage, showing a ring he said was a “pledge of his love” for Tecla, vowing he “would know how to do what was appropriate.”
3. On the morning of May 23, Idica was seen passing through an unusual path in the wood near Saturnino Llana’s house, where Tecla’s body was later found.
4. The blood-stained club piece found beside Tecla’s body had Idica’s initials and was identified by him as his own during the preliminary investigation.

The Court of First Instance of Ilocos Norte sentenced both defendants to fourteen years eight months and one day of reclusion temporal, indemnity, and costs. Both appealed.

ISSUE:
1. Whether the evidence presented was sufficient to establish the guilt of Silvestre Yadao beyond a reasonable doubt for the homicide of Tecla Llana.
2. Whether the evidence presented was sufficient to establish the guilt of Juan Idica beyond a reasonable doubt for the homicide of Tecla Llana.

RULING:
1. The Supreme Court reversed the judgment against Silvestre Yadao, finding the evidence against him to be isolated, uncorroborated, and insufficient to establish his guilt beyond a reasonable doubt. His alleged confessions were not deemed credible or conclusive enough in the absence of stronger corroborating evidence. He was thus absolved of the crime.

2. The Supreme Court affirmed the judgment against Juan Idica. The Court found a compelling chain of circumstantial evidence establishing his guilt: his unrequited love and extreme jealousy towards Tecla; his previous attempts to gain access to her and explicit threats to kill her if she married another; his lament over her impending marriage and declaration of intent to “do what was appropriate” (interpreted as killing her); his presence in the secluded wood where the body was found at daybreak on the day of the murder; and the discovery of the murder weapon (a club with his initials, identified by him) beside the victim’s body. The Court concluded there was no room for reasonable doubt that Idica, motivated by ungovernable passion and rejection, carried out his “perverse idea” to kill Tecla Llana. He was sentenced to fourteen years eight months and one day of reclusion temporal, with accessory penalties, and ordered to pay an indemnity of P1,000 to the heirs of the deceased.
