Neonaticide generally refers to the killing of an infant within the first month of life. It may be associated with many difficulties for pathologists and the courts, as the births have often been concealed and the victims' bodies hidden. The findings at autopsy tend to be nonspecific, particularly where the lethal event has involved suffocation, drowning, or failure to provide adequate care and support for the newborn. Differentiating stillbirth from live birth may not be possible. The flotation test is not a reliable indicator of prior respiration. If considerable doubts exist then stillbirth cannot be excluded.
