This book focuses on the importance of assessing risk in domestic violence cases to prevent and reduce its escalation into homicide (so called uxoricide). Spousal killers in a substantial number of cases exhibit a history of prior spousal violence: in addition to this, witnessing violence has debilitating effects on children. For this reason domestic violence is also becoming a hot political issue on the European agenda. Integrating the US and Canadian experiences with the European ones increases the book's value and broadens perspectives. Assessing the risk and adopting appropriate measures can help reduce the risk of escalation of violence. It aims at gathering contributions from experts in the field of domestic violence and victimisation to present state of the art research in the risk assessment of domestic violence cases.
