It looks like the rate they came up with is about 3-5% but all were living in rural areas without on going care and treatment. Pretty interesting. Looks like conditional release with mandatory on going treatment would make the most sense.

This is a poor study with respect to this situation. While you already discussed the issue with the most common offender being the minorities living in rural areas with limited access to treatment, there's just other areas that don't draw a parallel:

Since 2000, Chuvashia has had a high total homicide rate of about 14 per 100,000 per annum and a high homicide rate by people diagnosed with schizophrenia of about 0.45 per 100,000 perannum (Golenkov et al., 2011a)

Canada's homicide rate is about 1.5 per 100,000. You're 10x more likely to be murdered period in Chuvashia.


Here's a follow up by the same three authors.

This study suggests that in most jurisdictions, the rate of recidivist homicide offences by people with schizophrenia who have been released to community care is very low. There were no cases of homicide recidivism in New Zealand [36] or Austria [33] over periods of 30 and 25 years respectively. A low rate of recidivism was also suggested by the findings of most of the other studies from high-income countries conducted over shorter periods. Although it is not possible to draw firm conclusions about the reasons for these low rates of homicide recidivism, the most important factor in the prevention of further homicides by mentally ill offenders is likely to be the ability of forensic services to provide an adequate period of secure detention, carefully graded release to community settings and ongoing supervision of treatment after release.

This review was conducted after we published a study describing a high rate of homicide recidivism in Chuvashia [12]. Other researchers with similar findings might also be more likely to prepare a report and have it accepted for publication. Hence, there is a risk of publication bias towards reports of higher rates of recidivism, which appears to have been confirmed by our analysis of published versus unpublished data. However, the low rates of homicide recidivism in the unpublished data might also be a due to under-reporting, for example, as a result of the imperfect recollection of homicide recidivism by the primary researchers.

There was one case from New South Wales, Australia [6,13], and one case in a recent study from Saudi Arabia [26]. The authors of 8 other published studies from Austria [33], Australia (two studies from Victoria) [21,34], Barbados [35], New Zealand [36], The Netherlands [28], Nigeria [37] and Singapore [38] confirmed that there were no cases of recidivism in their samples. The authors of 3 studies from the UK confirmed the presence of some recidivists in their samples but they could not specify the number of cases [14,17,25]. Hence, of 29 studies reporting homicide offenders with schizophrenia from defined geographic regions, 3 studies reported homicide recidivism according to our definition

Despite significant limitations of the available data, our results suggest that repeat homicides by people with schizophrenia are rare in jurisdictions with low rates of total homicide and well developed services for the long-term treatment of homicide offenders with schizophrenia.
