G.R. No. L-49118 August 30, 1988
People of the Philippines, plaintiff-appellee, vs. Leticia Capitin y Vargas, accused-appellant.

FACTS

Leticia Capitin, a 22-year-old housemaid, was charged with parricide for smothering her two-month-old illegitimate child to death on December 10, 1975. Her employer, Soledad Caparas, discovered the incident and reported it. Leticia was investigated and signed an extrajudicial confession. During her initial arraignment, she appeared mentally disturbed, leading the trial court to order a psychiatric examination. Dr. Florante Reyles diagnosed her with schizophrenia, and she was committed to the National Mental Hospital.
In August 1977, Dr. Reyles informed the court that Leticia had sufficiently improved to stand trial. She was arraigned, and a plea of not guilty was entered. The trial proceeded while she remained confined at the hospital. The prosecution presented evidence, including the autopsy report confirming death by suffocation and the extrajudicial confession. The defense presented Leticia and Dr. Reyles, who testified that she was a schizophrenic at the time of the offense, suffering from a split personality that rendered her incapable of understanding her actions. The trial court convicted Leticia and sentenced her to reclusion perpetua.

ISSUE

Whether the accused-appellant is criminally liable for parricide, considering the defense of insanity.

RULING

The Supreme Court reversed the conviction and acquitted Leticia Capitin by reason of insanity. The legal logic centers on the burden of proof in insanity defenses and the evaluation of evidence. Under Philippine law, an accused is presumed sane, and the burden of proving insanity rests upon the defense. However, once evidence of insanity is presented, the prosecution must overcome it by proving guilt beyond reasonable doubt, as the constitutional presumption of innocence remains.
The Court found the prosecution failed to meet this burden. The defense presented compelling and unrebutted expert testimony from Dr. Reyles, who stated Leticia was schizophrenic at the time of the killing, a condition that likely existed months before the incident and rendered her incapable of comprehending the wrongfulness of her act. The prosecution’s evidence was insufficient to refute this. The extrajudicial confession was deemed invalid due to the accused’s observed abnormal behavior during its taking and the lack of competent counsel. The trial court’s selective credence—accepting the doctor’s certification for fitness to stand trial but rejecting his diagnosis on her mental state at the time of the crime—was erroneous. Consequently, reasonable doubt existed regarding her criminal responsibility. The Court ordered her recommitment to the National Mental Hospital until certified fit for discharge.
