G.R. No. 134583 ; July 14, 2004
PEOPLE OF THE PHILIPPINES, appellee, vs. FREDDIE MURILLO, appellant.

FACTS

Appellant Freddie Murillo was charged with the murder of his aunt, Paz Abiera. The information alleged treachery, evident premeditation, cruelty, and abuse of superior strength. Upon arraignment, with the assistance of a Public Attorney’s Office lawyer, Murillo pleaded guilty. The prosecution presented evidence showing that on June 12, 1997, a foul odor led to the discovery of dismembered body parts in the septic tank of the victim’s house, which she shared with Murillo and his brother. Murillo later confessed to the police. At trial, testifying as a hostile witness for the prosecution, Murillo detailed how his aunt scolded and slapped him, causing his vision to darken, after which he stabbed her, dismembered her body, disposed of the parts in the septic tank, and threw the severed head elsewhere.
The Regional Trial Court convicted Murillo of murder and sentenced him to death. The court found his open-court admission credible but held that only treachery qualified the killing to murder, dismissing the other alleged circumstances. The case was elevated to the Supreme Court for automatic review.

ISSUE

Whether the trial court erred in accepting Murillo’s plea of guilty and convicting him of murder based on an improvident plea.

RULING

Yes. The Supreme Court annulled the conviction and remanded the case for proper arraignment and trial. The Court found that Murillo’s plea of guilty was improvident. A plea of guilt to a capital offense must be made with full comprehension of its meaning and consequences. The trial record was utterly devoid of any showing that the judge conducted the requisite “searching inquiry” into the voluntariness and full comprehension of the accused’s plea, as mandated by jurisprudence. The defense counsel also failed in his duty to ensure his client understood the plea’s implications.
Furthermore, the plea was not corroborated by independent evidence of guilt. Apart from Murillo’s own testimony, the prosecution’s evidence was largely circumstantial and pertained to the discovery of the body, not the manner of killing. The corpus delicti—the fact of death by a criminal agency—was not conclusively established independently of the extrajudicial confession and the judicial admission. The Court emphasized that a conviction based on an improvident plea, especially in a capital case, constitutes a denial of due process and a miscarriage of justice, necessitating a remand for proper proceedings.
