Sudden unexpected death and covert homicide in infancy.

It is impossible to be certain, but it is estimated that each year in England and Wales there may be about 30-40 infant deaths from covert homicide, which represents about 10% of the current annual total of sudden unexpected deaths in infancy. This paper reviews the features that have been suggested as possible indicators of covert homicide, describes the difficulties in its identification and the need for better evidence, and emphasizes the importance of thorough medical investigation of all sudden infant deaths.
