Birmingham City University researchers Elizabeth Yardley, David Wilson, and Adam Lynes co-authored
[14] "A taxonomy of male British family annihilators, 1980–2013", examining British familicides in the period.
[15] Newspaper articles were used as references. The study concluded that most of the perpetrators were male. Men who murder their entire families usually do so because they believe their spouse performed a wrongdoing and that the spouse needs to be punished, they feel that the family members caused a disappointment, they feel that their own financial failings ruined the point of having a family, and because they wish to save their family from a perceived threat.
[16] Far fewer women commit familicide, and those who do usually have different reasons, including perceived or imagined loss of custody of children. Male family annihilators are typically driven by loss of control, including financial crises, separation or divorce, and may demonstrate evidence for domestic violence, while for women perpetrators, battery, abuse or mental illness is more common, the act itself more likely premeditated and more likely to include victims under the age of one.
