AI-generated summary
Lynn Marie Cannon, 51, was murdered by her estranged husband Paul Cannon on 5 December 2022 at his residence. After ending their 25-year marriage characterised by coercive control, she had begun a new relationship. When Paul Cannon discovered this, he became aggressively jealous, visiting her home with a knife and making threats. Her sister called police at 7:30pm reporting serious safety concerns. Police downgraded the response priority from P2 (immediate) to P3 (routine), changed the attending address to the victim's home, and failed to recognise escalating risk factors. The first responder arrived at 8:29pm, but Paul Cannon had already fatally stabbed Lynn. The coroner found no individual officer breached policy, but identified systemic failures in recognising domestic violence escalation, compounded by resource shortages and communication failures between agencies. The finding emphasises that intimate partner homicides are preventable through community-wide recognition of warning signs and whole-of-government responses to family violence.

Contributing factors
- Downgrading of emergency response priority from P2 to P3 based on incomplete risk assessment
- Insufficient police resources due to unanticipated surge in call volume (230 calls received versus 89 forecast)
- Failure to recognise escalating family violence risk and coercive control dynamics
- Absence of documented prior domestic violence incidents in police records
- Initial police direction to victim's home rather than perpetrator's residence
- Delayed police communication and response
- Repeated failures to establish communication between SJA and police PAC
- Lack of proactive questioning about risk factors by police communications staff
Coroner's recommendations
- Ensure full funding and implementation of the Family and Domestic Violence System Reform Plan (2024-2029) with twice-yearly progress reporting to Parliament
- Provide immediate significant funding uplift for frontline specialist Family and Domestic Violence Services to address current funding crisis and unmet demand
- Allocate funding for face-to-face Family Violence Division training for all frontline police officers across WA
- Develop and resource a whole-of-state, planned and coordinated bystander intervention approach to family violence prevention and education
- Ensure sustained funding for non-government specialist support services providing crisis response and ongoing support to victim-survivors and their supporters
- Continue monitoring and implementation of new WA Police dispatch procedures requiring senior sergeant approval for all priority downgrades
- Strengthen multi-agency information sharing frameworks and risk assessment protocols between police, health, communities and other agencies
- Develop alternative pathways for reporting family violence that do not require immediate police attendance, recognising barriers to reporting
