People tend to want to know the explicit details of crimes, including descriptions of violence and carnage. The author discusses her team’s research, and the research of others when possible, on the places where female serial killers (FSKs) commit their crimes, which typically includes a suburb, and the primary means FSKs use to commit murder, the most common of which is poison. The author presents information on the victims of FSKs, including the average number deceased, and victim age, vulnerability, familiarity, relatedness. Startlingly, more than half of FSKs killed children, more than three-quarters of FSKs killed someone vulnerable and in their care, more than 90% killed at least one person they knew, and more than 60% were related to at least one victim by blood or marriage. The cases of FSKs Tammy Corbett, Genene Jones, and Nanny Doss are presented to illustrate chapter concepts.
