A comparison of parricide and attempted parricide: a study of 39 psychotic adults

Excessive violence and psychotic symptomatology among homicide offenders with schizophrenia

“…For example, excessive violence in the context of homicides is more frequent among psychopaths (Porter et al, 2003) and has also been associated with intrafamilial homicides committed by psychotic offenders (Green, 1981;Marleau et al, 2003). Currently, it is not known how psychotic symptoms are associated with the nature of violence among homicide offenders with schizophrenia, or, more specifi cally, whether different psychotic symptoms are differentially linked with excessive violence.…”

Abuses and Distortions in Emotional Processes as Risk Factors for Parricide

“…It is a rare case of crime and it represents a minor percentage of the voluntary murders: in Europe and North America it has an incidence of about 2-4%, with a prevalence of patricides (Bourget, Gagné, and Labelle 2007;Ewing 1997;Heide and Petee 2007;Hillbrand et al 1999;Marleau, Millaud, and Auclair 2001;Marleau, Millaud, and Auclair 2003;Weisman and Sharma 1997), while in Italy the estimate does not reach 3%, 59% of which are matricides (EURES-ANSA 2010).…”

“…In most of the cases, the murder takes place in the family home, and the perpetrator and the victim are background does not seem to play a role (Ewing 2013;Greco, Curci, and Grattagliano 2009;Hart and Helms 2003;Heide 1993;Heide and Petee 2007;Hillbrand et al 1999;Marleau, Millaud, and Auclair 2003;Marvelli 2013). Marleau et al (2003) reported the features of 90% of the male parricides which took place in Canada between 1961 and 1989.…”

“…Marleau et al (2003) reported the features of 90% of the male parricides which took place in Canada between 1961 and 1989. The modality characterizing the murder is often violent and bloody, many times accompanied by "overkilling" (Bourget et al 2007).…”

“…Most of the adolescent parricide offenders act in reaction to experiences of physical or sexual abuses perpetrated by their parents (Grattagliano 2014;Grattagliano et al 2014;Lisi et al 2012;Lisi et al 2013). Instead, adult aggressors, usually between thirty and forty years of age, are psychiatric patients who commit the crime as a consequence of their mental illness (Heide 1992;Heide 1993;Heide 1994;Hillbrand et al 1999;Marleau et al 2003;Millaud, Auclair, and Meunier 1996;Shon and Targonski 2003;Weisman and Sharma 1997), as well as of precipitant factors, such as alcohol or drug abuse or the death of a significant other (Millaud et al 1996). These perpetrators are mostly single, unemployed or with part-time jobs and live together with the victim (Millaud et al 1996); they also have poor social relationships or are engaged in very few extra-familiar activities (Cooke 2001).…”
