Only when homicide, suicide and “accident” are ruled out can a death validly be classified as natural. For example, discovery of a dead infant, who apparently had been healthy and sleeping in his or her cot just prior to death, might implicate the Sudden Infant Death Syndrome or SIDS as the killer. Obviously suicide can immediately be ruled out. But more investigation, typically involving the Medical Examiner or Coroner’s Office, would be necessary to eliminate homicide or “accident” as the cause of the infant death.
