ligature compression of the neck (hanging) in a man with methadone and methylamphetamine consumption
AI-generated summary
Kingsley Garlett, aged 32, died by hanging in a maximum security prison cell on 31 July 2022. The evidence indicates his death was an impulsive response to relationship conflict with his partner revealed through prison phone calls. Critical clinical lessons emerge: the deceased had emotionally unstable personality disorder and polysubstance use disorder but did not warrant psychiatric hospitalization. However, he was able to access illicit drugs (methylamphetamine, cannabis) and prescription medications he was not prescribed (amitriptyline, quetiapine, diazepam) while incarcerated. These substances impaired his decision-making and impulse control, significantly increasing suicide risk in a prisoner with known personality vulnerabilities. The coroner found supervision inadequate regarding drug access. The cell lacked ligature minimisation despite known suicide risk principles. Recommendations focus on urgent ligature safety upgrades, expanding addiction treatment programs (methadone/buprenorphine), updating prison drug strategies, and increasing mental health staffing—lessons applicable to secure mental health and correctional settings where vulnerable populations face environmental suicide risks.

Coroner's recommendations
As a matter of utmost urgency, take immediate steps to ensure all cells at Casuarina are three-point ligature minimised as quickly as possible, with a view to ensuring all cells are fully ligature minimised over time. Finalise review of bunk beds and ensure all bunk beds are fit for purpose and can be described as 'ligature approved'.
Implement a replacement strategy for the expired Western Australian Prisons Drug Strategy 2018-2021 to provide strategic guidance to efforts to reduce the flow of illicit substances into prisons and to provide harm and demand reduction support to prisoners.
Government should reconsider the Department of Justice's submission for funding for additional Aboriginal support workers, counsellors and mental health professionals noting the critical need for such positions across the Western Australian custodial estate.
Consider expanding methadone and buprenorphine programs so that the wait time for prisoners to enter these programs is reduced.
