Facts:

Rodolfo Caguioa, Sr. was charged with two counts of rape against his daughter, Aurora Caguioa, in separate Informations. The first count (Criminal Case No. L-4494) alleged that on or about the first week of April 1991, Caguioa caused Aurora to lose consciousness by making her smell a chemical, after which he had carnal knowledge of her while she was unconscious. The second count (Criminal Case No. L-4495) alleged that on or about the second week of April 1991, Caguioa threatened Aurora with a knife, compelling her to submit to his sexual advances.

Aurora, a 15-year-old girl, had returned home for a vacation from her job as a domestic helper. On April 5, 1991, while alone in her room, she was attacked by a man who placed a cloth over her face, causing her to lose consciousness. Upon waking, she discovered signs of sexual abuse but did not initially know the identity of her assailant. On April 10, 1991, while alone with her father, Caguioa threatened her with a knife and raped her. After the incidents, Aurora sought refuge with her brother and later disclosed the abuse to her employer, who assisted her in reporting the matter to the authorities.

The National Bureau of Investigation (NBI) conducted an investigation, during which Aurora identified her father as the perpetrator. Medical examinations confirmed signs of sexual abuse, and Aurora later gave birth to a child, Babellin Caguioa, who resembled Caguioa.

Caguioa was found guilty of both counts of rape by the trial court, which sentenced him to reclusion perpetua (life imprisonment) for each count and ordered him to pay civil indemnity to Aurora.

Legal Issues:

  1. Whether the evidence presented was sufficient to establish the guilt of Caguioa beyond a reasonable doubt for both counts of rape.
  2. Whether the defense of alibi presented by Caguioa was credible and sufficient to exonerate him from the charges.
  3. The admissibility of Caguioa's Sinumpaang Salaysay (sworn statement) admitting to the crime.

Arguments:

  • Prosecution's Argument: The prosecution relied heavily on the testimony of Aurora, who provided a detailed account of the rapes, including the threats made by her father. The prosecution argued that the evidence, including medical findings and the victim's identification of Caguioa, was sufficient to prove his guilt beyond a reasonable doubt.

  • Defense's Argument: Caguioa's defense was primarily based on alibi, claiming he was working in a rice field at the time of the second incident and did not return home. He also contested the admissibility of his Sinumpaang Salaysay, arguing that it should not be considered as evidence against him.

Court's Decision and Legal Reasoning:

The court affirmed the conviction for the second count of rape (Criminal Case No. L-4495) but reversed the conviction for the first count (Criminal Case No. L-4494). The court found that the prosecution had established Caguioa's guilt for the second incident through Aurora's credible testimony, which was corroborated by medical evidence. The court emphasized that the victim's identification of her father as the rapist was compelling and that the defense of alibi was weak, as it was not supported by credible witnesses and did not demonstrate physical impossibility for Caguioa to be at the scene of the crime.

Regarding the first count, the court determined that there was insufficient evidence to prove that Caguioa had raped Aurora on April 5, 1991, as her testimony did not definitively identify him as the perpetrator of that incident. The court noted that Aurora's admission of not knowing who raped her the first time weakened the prosecution's case for that count.

Significant Legal Principles Established:

  1. The testimony of a rape victim is given great weight, especially when there is no evidence of ill motive to fabricate the accusation.
  2. Alibi is considered a weak defense, particularly when it is not corroborated by credible witnesses and does not demonstrate physical impossibility.
  3. The court can reverse a conviction if the evidence does not sufficiently support the charges, even if the accused has been found guilty of other related offenses.
