Abstract:
BACKGROUND : Most of the available literature focus on characteristics of violent offenders and
trends of crime patterns in the general population. The crime trends in the population of those
who may be mentally ill have not been well described.
AIM : To describe the profiles and trends of mentally ill persons who committed violent crimes
prior to admission as state patients.
SETTING : The study was conducted at Weskoppies Psychiatric Hospital.
METHOD : A retrospective record review of state patients admitted between 2005 and 2014 was
conducted to describe demographic, clinical, forensic and victim profiles of state patients
admitted from 2005 to 2014. Trends over time were also assessed.
RESULTS : Hundred and seventy state patient files were reviewed. The majority were males
(91.43%), with a history of substance use (55.0%) %), previous psychiatric treatment (46.4%),
and diagnosed with a psychotic disorder (82.1%). The 10 year trend showed that murder was
the leading charge during 2006 and 2007. It was surpassed by sexual assault crimes as the most
common charge after 2007, except for 2009 when murder was again the most common. From
2010 onward, sexual assault remained the most common offence leading to admission as a
state patient.
CONCLUSION : This study found changes over time in crime patterns of state patients who
committed murder and sexual assault. State patients may have different criminal patterns
than the general public. This together with the high rates of substance use and previous
psychiatric treatment can be important focus areas for future research.
