William Johannes was released from Humber Memorial Hospital in December 1996 after 10 weeks of involuntary hospitalization sought by his sister Roslyn Knipe 

He went straight to his sister’s apartment. No one from the hospital had warned her that William had been released

He expressed bizarre conspiracy theories, complaining that he was under police surveillance

William returned to Humber Hospital on three occasions

He was charged for trespassing on one occasion, and spent a night in jail

He was provocative, irritable, and hostile to Roslyn the  morning before the killing 

William killed Roslyn at her home on January 24, 1997, possessed by the notion that she was the devil

“Roslyn had been stabbed more than 50 times, a fist‐sized cavity carved into her chest. He had been possessed by the notion that his sister was the devil...” (Makin, 2007, p. 83)

William was found Not Criminally Responsible (an equivalent verdict of NGRI) and placed under the jurisdiction of the Ontario Review Board (ORB) in Canada

What can clinicians do to prevent similar tragic incidents from happening?

What are the available tools to assist clinicians in managing and reducing the risk of occurrence of similar severe/fatal violence?

Identify risk factors of acute severe/fatal violence to assist“…as soon as possible, in preventive clinical actions such as change in medication, monitoring, and admitting to or discharge from hospital” (Tardiff, 2008, p. 3)

Propose a screening tool in clinical settings with comparable predictive validity to validated violence risk assessment tools to assess acute risk (within days to a week) of severe/fatal violence to victims among persons with SMI

Inconsistent definitions of violence among research with a wide spectrum of violent acts from verbal threats to homicide (Bo, Abu‐Akel, Kongerslev, Haahr, & Simonsen, 2011)“…leaving unanswered the question of whether mental illness predicts some kinds of violence but not others.” (Elbogen & Johnson, 2009, p.153)

Research has shown a modest but significant positive association between mental illness and violence (Fazel, Gulati, Linsell, Geddes, & Grann, 2009)

Family members have a higher prevalence of being victims of violence, of varying degrees of severity, by their mentally ill relatives, compared to non‐family members (Davis, 1991; Taylor, 2008)

57% of victims of assaultive behaviors, prior to admission to a private hospital, were spouses/mates and “other family members” (Tardiff, 1984)47% of the victims of physical violence were family members (mainly parents and spouses) within two weeks of admission (Straznickas, McNiel, & Binder, 1993)24‐38% of caregivers sustained physical assault in the past year (Swan & Lavitt, 1988; Vaddadi, Gilleard, & Fryer, 2002)18% of caregivers experienced an injury within the past year (Chan, 2008)

Between 73% and 79% of victims of homicide were family members of psychotic offenders (Gottlieb, Gabrielson, & Kramp, 1987; Nielssen, Westmore, Large, & Hayes, 2007) vs. 49% of family members being victims of non‐psychotic defendants (Gottlieb et al., 1987)23% of family of origin or a spouse/partner as victim of severe/fatal injury by offenders with schizophreniaRespective odds ratios of 5.10 and 3.29 of becoming a victim of severe/fatal injury, compared to strangers (Nordström & Kullgren, 2003)
