Childbirth after denial or concealment of pregnancy has an increased risk of mortality for both mother and child. Interdisciplinary cooperation between professional groups is needed to explore the psychological and criminological aspects of infanticide. The case of a primipara mother, who threw her mature and viable newborn from the 10th floor of a high-rise building shortly after a concealed pregnancy, is reported. Forensic medical issues, as well as the characteristics of the offence and the perpetrator, are described.
