G.R. No. 138453 - People vs. Robinos y Domingo

On March 25, 1995, at around 7:00 a.m. in Barangay San Isidro, Municipality of Camiling, Tarlac, the accused Melecio Robiaos y Domingo allegedly committed the complex crime of parricide with unintentional abortion by fatally stabbing his legitimate wife, Lorenza Robiaos, who was six months pregnant.
The murder was perpetrated using a double-bladed knife approximately eight inches in length, inflicting multiple (specifically, 41) stab wounds, which resulted in the instantaneous death of both the victim and the fetus in her womb.

The triggering incident arose amidst a domestic altercation, wherein heated exchanges reportedly preceded the fatal act. Testimony from the 15-year-old son, Lorenzo Robiaos, indicated that his mother had made remarks implying the accused should leave, which escalated the conflict.
Amidst the quarrel, the accused deliberately attacked his wife; blood was observed dripping from a portion of the house, a detail corroborated by police and barangay officials who later intervened.
The criminal act was immediately witnessed and reported by family members, resulting in a swift police response. The accused was apprehended and his confession was obtained during the intervention.

Testimony by Lorenzo Robiaos, the son, recounted the verbal dispute and observed the stabbing as it took place.
Benjamin Bueno, the victim’s brother, provided emotional and corroborative testimony after having been forewarned about earlier violent incidents within the family; he also recounted his own experience of fear when confronted by the accused after the incident.
Barangay officials and law enforcement officers (including SPO1 Herbert Lugo and SPO3 Tirso Martin) detailed the discovery of the crime scene, the removal of a bamboo wall to expose the area of the assault, and the acts of restraint employed against the accused.
A barangay kagawad, Rolando Valdez, testified that upon arriving at the scene he observed the accused confessing to the killing and presenting the bloodstained knife as evidence of his guilt.

The accused was subsequently taken into custody and later arraigned on July 27, 1995. Despite pleading not guilty, the weight of the evidence led the Regional Trial Court (RTC) of Camiling, Tarlac (Branch 68) to convict him in Criminal Case No. 95-45.
The prosecution’s evidence and witness testimonies were not countered with a substantial refutation regarding the act itself; rather, the defense accepted the commission of the crime and interposed a plea of insanity to exculpate the accused.
The defense advanced that the accused was suffering from psychosis or schizophrenia at the time of the crime, presenting testimonies from fellow detainees, his son Federico Robiaos, and Nurse Lourdes Fajardo, as well as a psychiatric evaluation by Dr. Maria Mercedita Mendoza.
Dr. Mendoza’s evaluation, however, was conducted approximately six months after the incident and was based on an incomplete review of the accused’s prior mental health history, rendering her conclusions largely conjectural.

Based on the facts, the RTC convicted the accused of parricide with unintentional abortion and sentenced him to the death penalty by lethal injection, in accordance with the Revised Penal Code’s provisions regarding complex crimes and applicable penalties.
The sentencing was premised on the complex nature of the crime and the statute’s allowance for a penalty composed of two indivisible penalties (reclusion perpetua to death), without due consideration of potential mitigating circumstances.
The case was automatically elevated to the Supreme Court for review, prompting the issues now before this appellate body.

Whether the trial court erred in not giving sufficient weight to the testimony and the psychiatric evaluation by Dr. Maria Mercedita Mendoza, which purportedly indicated that the accused was suffering from psychosis or insanity (classified under schizophrenia, paranoid type) at the time of the commission of the crime.
Whether the evidence presented was adequate to prove that the accused was completely deprived of reason, discernment, and freedom of will—elements essential for establishing the exempting circumstance of insanity.

Whether the trial court erred in imposing the death penalty despite the existence of two indivisible penalties for parricide with unintentional abortion, especially in the absence of aggravating circumstances.
Whether, by law, the imposition of the lesser penalty (reclusion perpetua) should have been mandated instead of the death penalty when neither aggravating nor mitigating factors warranted the harsher penalty.
