People v. Pilen

Summary

This Supreme Court case involves Jonie Sabandal Pilen who committed a killing spree on July 14, 2013, in Southern Leyte, using a bolo to attack 13 victims, killing 3 including a 1-year-old child. Originally charged with multiple murder counts, the case centered on whether the killings qualified as murder or homicide based on the presence of treachery, and whether Pilen's insanity defense was valid. The Supreme Court ruled that treachery only applied to the 1-year-old victim due to her tender age, reducing other charges to homicide. The Court rejected Pilen's insanity defense for lack of medical proof, despite evidence of drug intoxication. The decision clarified important principles on defective informations being waived through failure to object, treachery in child victims, and the burden of proof for insanity defenses. Pilen was ultimately convicted of 1 count murder, 2 counts homicide, 7 counts frustrated homicide, and 3 counts attempted homicide.
