Randall Coleman, 39, died from strychnine toxicity after deliberately ingesting poison while in custody at Kingaroy watchhouse on 18 January 2007. He had secreted the vial on his person at arrest on 16 January, despite police searches. The coroner found that Coleman was suffering from depression, relationship breakdown, legal stressors, and was receiving counselling. He had formulated a clear plan to end his life and concealed his intention. Police response to his poisoning was prompt and appropriate, and medical treatment at Kingaroy Hospital was timely and reasonable. However, key clinical lessons include: failures in completing health/medication assessment forms at watchhouse admission despite signs of medication effects; lack of systematic suicide risk screening in police custody (compared to correctional facilities); and the challenge of identifying elevated suicide risk when prisoners experience multiple stressors and are moved between facilities repeatedly. The coroner recommended considering enhanced risk assessment procedures for remanded prisoners, particularly when bail is refused.

Coroner's recommendations
Allocate resources to enable more effective monitoring of prisoners at Kingaroy police station, noting the additional burden of managing increased prisoner numbers during District Court circuits without a designated watchhouse keeper
Prioritise funding for the planned new Kingaroy police and watchhouse facility
Consider heightened awareness of suicide risk in police custody when bail is refused, particularly when prisoners have multiple stressors
Consider whether Department of Corrective Services-style risk assessment procedures for suicide could be implemented for remanded prisoners in police custody, with appropriate expert personnel
Ensure completion of health, medication and personal assessment forms at watchhouse admission, with clear delegation of responsibility when the admitting officer must leave the station
Consider systematic screening for elevated suicide risk when prisoners are transferred between facilities or when significant new stressors are identified (e.g. removal of children, bail refusal)
Ensure mental health referral information and suicide risk indicators from Child Safety Officers and other agencies are clearly communicated to custodial staff in terms that identify specific risks
