Filicide, the killing of a child by their parent or caregiver, is estimated to account for 18 to 25% of family homicide cases in Australia. Filicide often involves multiple victims and has a devastating effect on both families and communities. Despite this, comparatively little is known about it.
Because of differences in jurisdictions around reporting and legislation, child deaths are recorded and analysed individually by states and territories. National publications that analyse police data are limited, and only report aggregate data.
This broad approach precludes any in-depth analysis of risk factors and circumstances around individual cases, resulting in a somewhat piecemeal understanding of child-abuse-related fatalities.
Understanding filicide is particularly difficult because it is uncommon. However, given the impact it has on communities, it is necessary to examine some converging risk factors to understand where individual and situational factors combine to increase the risk.
Existing research indicates mental illness, previous abuse, and domestic violence are risk factors for filicide.
Combining these factors may develop a more nuanced perspective of filicide. This is particularly important given the diversity of families in contemporary Australia. Separation, divorce and other complex living arrangements for children have broadened the concept of families, making a more detailed approach warranted.

Focusing on family relationships to identify risk
Our research aimed to identify similarities and differences between cases of filicide according to victim-perpetrator relationship.
From the National Coronial Information System, we identified 118 child victims, nine adult victims and 26 suicides involving 97 perpetrators. Information about the circumstances surrounding the cases was obtained from autopsy reports, toxicology reports, police reports, Supreme Court judgements, and media reports.
We identified five main victim-perpetrator relationships at the time of the incident. There were too few cases involving a de facto female, separated mother, and single father to include in our analysis.
Analysis using these categories revealed some interesting patterns in relation to the more likely circumstances surrounding filicide perpetrated by particular family members.
For example, although mental illness was common among all perpetrators, female perpetrators were most likely to have a diagnosed mental illness. Male perpetrators were more likely to have had prior contact with the criminal justice system.
However, substance abuse was not a distinguishing factor for any perpetrator, gender or relationship.
Separated fathers were more likely to have had custodial issues at the time of the fatal incident. Homicides committed by this group were more likely to involve multiple children and/or other adult victims and suicide.
Where there were multiple child victims, they were more likely to have been administered sedatives before death.
Prior to the filicide incident, separated fathers were often described as loving, whereas coupled fathers were more likely to have had a history of intimate partner violence.
In contrast, de facto fathers were more likely to have abused the child in the events leading up to the fatal incident. However, they were least likely to commit suicide at the time of the incident.
In terms of the cause of death, violent deaths (resulting in head/spinal injuries or multiple abdominal injuries) were more common for victims of male perpetrators. This was particularly the case with de facto males. Female perpetrators most commonly killed by asphyxiation.
Applying this research to prevent filicide
Because it is uncommon, and the perpetrator is often unknown to services prior to the event, predicting filicide is almost impossible. Preventing filicide, however, may be possible in some cases.
Filicide crimes are highly variable and like all classification systems, there are limitations. However, the more likely that research identifies patterns that have an application for practice, the greater the opportunity for prevention.
Given that filicide involves parent or caregiver perpetrators, understanding the various contexts in which it occurs is one way to raise awareness of children at risk of serious abuse. This is particularly important in child protection, but equally so in community corrections, primary health care, and maternal and child health settings.
An improved understanding of the circumstances in which filicide occurs may contribute to its prevention by improving the ability of practitioners to identify high-risk cases. This would be aided by the systematic collection and analysis of information across all Australian jurisdictions.
