Coroner's Finding: HULSINGA Michael John

27y · Male·left temporal intracerebral haemorrhage due to arteriovenous malformation

Michael John Hulsinga, a 27-year-old male inmate with schizophrenia, died in custody from a spontaneous intracerebral haemorrhage due to arteriovenous malformation. He collapsed suddenly while eating dinner in his cell and was discovered approximately 4 hours later at 8:15 pm by nursing staff conducting a medication round. Post-mortem examination confirmed rapid onset of symptoms with massive bleeding that would have caused quick loss of consciousness. Even if discovered promptly, surgical intervention was unlikely and survival would have resulted in severe disability. The critical clinical lesson is recognizing that AVM can present acutely without warning; however, the main institutional failure was a correctional officer's false documentation of prisoner checks and failure to maintain 2-hourly welfare observations per protocol. This systemic lapse, while not altering the fatal outcome in this case, undermined prisoner safety procedures.
