Book excerpt: Every year, nearly half of the more than 20,000 murder victims in the United States are related to or acquainted with their killers. Fatal Families explores the social, cultural and psychological forces, as well as the nature and consequences that lead people to kill members of their own families. Drawing on his professional background in law and psychology, and using case studies, Charles Patrick Ewing points the way to measures that can be taken to reduce the terrifying number of murders within families.
