G.R. No. L‑2892
United States v. Felix Ortega
November 16 1906

—

FACTS
– On 5 April 1903 the defendant, Felix Ortega, a person falsely representing himself as a licensed physician, prescribed and caused the administration of chloral‑hydrate to a six‑day‑old infant, Carlos Clark.
– The infant received two teaspoons of the preparation (approximately two grains per dose) within a few hours and died later that night.
– The prosecution alleged that Ortega’s act, if done with malice, would constitute murder; alternatively, that his reckless negligence caused homicide.
– Ortega had previously been convicted (23 Sept 1903) for practicing medicine without a license and was pardoned on 8 Dec 1903.
– Expert testimony (Dr. Carter, Dr. Newberne, Dr. Musgrave, and P.G. Woolley) agreed that the administered dose was “exceedingly dangerous” for a neonate and could likely cause death, but none could definitively prove that the dose actually caused the infant’s death. No autopsy or death certificate indicated an abnormal cause of death.

ISSUE
Whether the prosecution proved beyond reasonable doubt that Ortega’s administration of the chloral‑hydrate caused the death of the infant, thereby establishing homicide through reckless negligence (or murder if malice is shown).

RULING
The Supreme Court held that liability for homicide requires positive proof that the accused’s act was the actual cause of death. Mere possibility, probability, or expert speculation, without a post‑mortem or conclusive medical evidence, does not satisfy the burden of proof. Consequently, Ortega could not be convicted of homicide (reckless negligence) nor of murder.

The judgment of the lower court was reversed; the defendant was acquitted and awarded costs de officio. The case was remanded for execution of the judgment.
