Key Facts About Filicide

Filicide – the killing of a child by a parent, stepparent, or equivalent guardian, is a devastating universal form of family violence. It challenges our deepest assumptions about parental care and demands focused attention.

Understanding Filicide

Definition
Filicide involves biological parents, stepparents (often mothers’ live-in partners), and, less commonly, guardians like grandparents or carers.

Forms of Filicide

  • Neonaticide: Killing of a newborn
  • Infanticide: Killing of a child aged 0–2 (age range and penalties vary by country)
  • Familicide: Killing of all family members, including the non-offending parent, often followed by the perpetrator’s suicide
  • Filicide–Suicide: Killing of a child or children followed by the perpetrator’s suicide

What We Know

  • Who Commits Filicide?
    Mothers and fathers kill in similar numbers, but stepparents — particularly stepfathers — are over-represented.
  • Global Perspective
    Research from Australia, the Americas, Europe, Asia, and Africa shows consistent patterns despite cultural differences.
  • Trends
    After decades of stability, filicide rates have risen in recent years — potentially linked to pandemic-related pressures.
  • Poverty Not a Primary Driver
    Higher-income countries like Australia, the US, and the UK report higher incidence rates, challenging previous assumptions.

Key Risk (Lethality) Factors

Filicide often involves a constellation of risk factors, varying by perpetrator type:

Currently, no risk patterns have been clearly identified for parents acting together.

Victims

  • Aged under 5
  • Chronic illness or disability
  • Hospitalisation at birth

Fathers

  • Living with/near a child under 5
  • Intimate partner violence
  • Mental illness
  • Child abuse
  • Substance abuse
  • Criminal history
  • Threats to kill (reported to authorities)
  • Service avoidance
  • Recent separation

Stepfathers

  • Living with/near a child under 5
  • Intimate partner violence
  • Mental illness
  • Child abuse
  • Substance abuse
  • Criminal history
  • Threats to kill (reported to authorities)
  • Service avoidance
  • Recent separation

Mothers

  • Living with a child under 5
  • Mental illness
  • Victim of domestic violence
  • Recent separation
  • Recent migration
  • Disengagement from services

Why It Matters

Understanding filicide requires examining how risk factors interact. For example, a migrant mother experiencing depression and abuse, or a father who is violent toward both partner and child.

A key finding: disengagement from services is a major warning sign. Many perpetrators are known to services but fail to engage. Strengthening early intervention and improving access could be crucial to prevention.
