G.R. No. 217111 - Alfiler vs. Spouses Cayabyab

On 22 June 1991, Dionito Fernandez was cutting grass at his residence in New Cabalan, Olongapo City when accused Rodolfo Villa, Jr.—a CAFGU member and neighbor—emerged wielding his M-1 Garand rifle.
Without warning, Villa shot Dionito from behind, killing him instantly.
In response, Ronald and Sheila Fernandez, children of the victim, rushed out to rescue their father; in the process, Ronald was fatally shot while embracing his father, and Sheila sustained mortal wounds to the thigh and stomach.
Neighbor Samuel Eclevia intervened to wrestle the rifle from Villa, only to also be shot dead.

After committing the murders, Villa surrendered to Captain Dolino of the Olongapo Metropolitan District Command (S2 OMDC).
Villa was charged with multiple counts of murder and, upon arraignment on 3 October 1991, initially pleaded not guilty.
Soon after, his counsel, Atty. Cipriano Dumpit, announced in open court that the accused wished to change his plea to guilty, while simultaneously invoking a self-defense argument, claiming that Dionito Fernandez had attacked him with a bolo.

The trial court questioned the accused to ascertain his understanding of the nature and consequences of his change of plea and, satisfied with his responses, allowed the plea amendment.
On 16 July 1992, Atty. Romeo Alinea was appointed counsel de oficio in view of Dumpit’s unavailability due to ongoing medical treatment.
Shortly thereafter, Atty. Alinea expressed his inability to confer with Villa properly and moved for a psychiatric evaluation at the National Center for Mental Health (NCMH), which was granted.
Villa was examined at the Olongapo City General Hospital by Dr. Romeo Enriquez, who recommended his subsequent confinement at the NCMH’s Forensic Pavilion for a detailed evaluation concerning possible insanity.

On 4 November 1994, Villa was confined at the National Center for Mental Health under the supervision of Dr. Celeste A. C. PeAa and Dr. Isagani S. Gonzales for further psychiatric evaluation regarding his mental state before, during, and after the commission of the crimes.
On 21 December 1994, following over a month of psychiatric observation, the attending physicians submitted an evaluation report indicating that Villa was suffering from an insanity or psychosis classified as schizophrenia. It noted deterioration in his social and occupational functioning, auditory hallucinations, delusions, thought disturbances, and poor judgment, rendering him incompetent to stand trial at that time.
On 5 June 1995, a follow-up psychiatric report by Dr. Cheryl Zalsos indicated that Villa’s condition had improved sufficiently to withstand the rigors of trial.
Acting on these developments, the trial court, on 21 June 1995, granted a petition for Villa’s release from further confinement, allowing the trial to resume with the defense of insanity being raised.

During the trial, Villa’s defense pivoted to an insanity plea, supported by the psychiatric reports and testimony from experts affiliated with the NCMH.
Villa submitted a detailed Sworn Statement recounting the events surrounding the killings, which included his actions immediately after the murders and his subsequent surrender to the authorities.
Despite references in the Sworn Statement and some mention by Dr. Zalsos in passing, the psychiatric reports failed to unequivocally establish that Villa was suffering from a complete deprivation of reason at the time of the crimes.

The primary issue was whether accused-appellant Rodolfo Villa, Jr. was insane at the time he committed the murders, thereby exempting him from criminal liability.
Secondary issues included:

The sufficiency and credibility of the psychiatric evidence presented to support an insanity defense.
The effect of Villa’s immediate actions after the crimes (such as intent to surrender, expressions of remorse, and a lucid and detailed Sworn Statement) on establishing his mental competence during the commission of the offenses.
