Children account for 10-20% of all homicide victims in Australia, UK, Canada and US. The most vulnerable time has been found to be the first year of life and, in particular, the first day of life. Unlike other forms of homicide where men are by far the most likely perpetrators, studies show that women are just as likely as men to commit child homicide. Using these findings, the authors of this book arrange their investigations along the dual lines of gender and position inside or outside the family. They ask who are the most likely killers of infants - mothers or fathers? Who are the most likely killers of adolescents - family or outsiders? They also consider patterns in suicide/homicides. This compelling study draws on Australian case studies and includes comparative statistics from the UK and North America. It will be useful to a wide interdisciplinary readership of scholars and students.
