AI-generated summary
A 51-year-old man with documented mental health issues including psychosis, paranoia, and delusions died from self-inflicted stab wounds during a police siege at his mother's home. He had breached a domestic violence order and was armed with a knife. Police deployed negotiators and tactical units over 11+ hours. Key clinical lessons: (1) Information from mental health services (obtained from Orange mental health line) was not communicated to negotiators or the consulting psychiatrist, though evidence suggests this would not have changed the outcome. (2) Police should have gathered more detailed information from family members, who knew SB's history and recent self-harm allegations better than anyone. (3) The decision-making and tactical response were appropriate; the outcome could not have been prevented by different negotiation approaches. (4) Multi-agency collaboration in mental health crises involving police requires systematic information-sharing protocols.

Coroner's recommendations
- Improve systematic information-sharing protocols in high-risk incidents, particularly to ensure information from multiple sources (including mental health services) is communicated to negotiators and consulting experts via platforms such as iPad-based iSurv App being rolled out to negotiators and tactical units.
- Police should make more substantial efforts to gather information from family members during mental health crises and siege negotiations, as families often know the person better than anyone and can provide critical contextual information.
- Ensure protected persons under domestic violence orders have thorough understanding of their rights to seek variation or rescission of orders, particularly where family members may have legitimate reasons to maintain contact for safety or welfare monitoring.
- Consider requesting documents or items from third-party intermediaries (such as friends) even if they are not directly involved in negotiations.
- Continue expansion of mental health crisis response training for all police, and consider broader implementation of PACER (Police, Ambulance, Clinician, Early Response) programs to support police in responding to mental health emergencies.
