Caitlin O’Brien knew she was in danger.

 

In messages before her death, she told her partner she was afraid of him:

 

“You murdering me.” (reported by ABC News)

 

The next day, he did.

This was not unpredictable.

This was not sudden.
And it was not just a “mental health issue.”

It was domestic violence. Escalating, documented, and missed.

 

This Was Not a Tragedy Without Warning

According to the Coroner’s findings, there were clear and repeated indicators of serious risk:

-A history of strangulation — one of the strongest predictors of homicide
-Threats to kill
-Escalating patterns of violence and coercive control
-Multiple interactions with police and health services
-Incidents often treated as mental health crises instead of family violence
-The perpetrator was released from hospital the day before Caitlin was killed
Despite this, no effective protective intervention prevented her death.

 

We Live With A System That Misses What Is Right in Front of It

Caitlin’s death exposed critical failures across systems:

• Family violence risk was not consistently identified or escalated
• Police responses did not always reflect the true nature of the risk
• Information was not effectively shared across services
• Responsibility was placed on Caitlin to seek help — instead of systems acting to protect her
• Even where warning signs were known, they were not treated with the urgency required to prevent a fatal outcome.

When responsibility for both mental health and family violence sits across overlapping systems, responses can become blurred particularly where immediate safety and violence risk require a different, more urgent approach than clinical treatment.

Mental Health SHOULD NOT Override Violence Risk

The perpetrator’s mental health history was complex and evolved over time.

However:

• Protective action should not depend on reaching a definitive psychiatric diagnosis when clear indicators of lethal domestic violence risk are already present.
• Psychiatric evidence in the case also raised questions about the reliability of aspects of the perpetrator’s reported paranoia and delusions showing that the mental health narrative was not straightforward.

Yet, the well-documented history of violence, threats, and escalation did not receive the same level of response.

 

What Needs to Change🫶🏻

Caitlin’s death must lead to reform.

 

We call on the Victorian Government, Victoria Police, and health services to:

 

1. Introduce mandatory domestic violence screening in all mental health responses
2. Automatically classify strangulation as high-risk, triggering immediate protective action
3. Ensure police conduct and act on family violence history checks
4. Improve information sharing between police, hospitals, and services
5. Shift responsibility off victims and onto systems to act proactively
6. Provide training to recognise coercive control and perpetrator manipulation

Higher minimum sentences for intimate partner violence

 

Even after Caitlin’s death, aspects of the case were framed in ways that focused heavily on the perpetrator’s mental state and level of culpability.

This risks obscuring the reality that this was a case of escalating domestic violence, with clear warning signs that were known before her death.

 

How these cases are described matters, because it shapes how seriously domestic violence risk is understood and responded to.

 

Even in the legal proceedings that followed, aspects of the case were described in ways that centred the perpetrator’s circumstances and level of culpability, rather than the well-documented history of domestic violence and escalating risk faced by Caitlin.

 

Caitlin Should Still Be Here…

Her death was not inevitable.

It followed repeated warnings that were not acted on.

when domestic violence is minimised, mislabelled and misunderstood, lives are lost.
