Homicide Followed by Suicide in Finland: Trend and Social Locus

The specifics of homicide-suicide in France

BACKGROUND

Homicide and suicide are two causes of violent death. This study focuses on situations in which these two types of violent death occur at the same time, known as homicide-suicide.

AIM

The aim of this study is to review the circumstances surrounding homicide-suicides as well as the features of the victims and perpetrators in France at a recent period. The article characterizes homicide-suicides by comparing them with simple homicides in order to determine whether they exhibit distinctive characteristics and significant links.

METHODOLOGY

The data analyzed are based on detailed police operational information collected about 1622 homicides that occurred in France in 2019 and 2020. After presenting the characteristics of all homicide-suicides, this article specifically compares those that take place within the family, whether they result in the suicide of the perpetrator or not, using bivariate tests (chi-square). The tests are based on a distinction between domestic homicide-suicides within a couple and between other family members.

RESULTS

Analysis shows that 7 % of them were followed by the suicide of the perpetrator (203 cases). Almost all of them take place within family (91 %), and most often within the couple (60 %). Apart from couple configurations, familial homicide-suicides target the children (21 %) or parents (5 %) of the perpetrators. The perpetrators are mainly men, while most of the victims are women. Analysis revealed significant links between certain variables and suicide (or attempted suicide by the alleged perpetrator) in the context of couple homicide: the modus operandi, the spatio-temporal setting, the gender and average age of the victim and history of domestic violence suffered by the victim, as well as all the variables relating to the alleged perpetrator (age, gender, police and psychiatric history, alcohol consumption, etc.). Among other family members, these variables do not have a significant influence on whether the perpetrator commits suicide following the homicide. Perpetrators of domestic homicide-suicides are less likely to be under the influence of alcohol (8 %), to be known to the police (19 %), and to have a psychiatric history (11 %) than those who do not commit suicide following the homicide (respectively 41 %, 54 %, 22 %). There is also less record of domestic violence when the perpetrator commits suicide (20 %) than when they do not (48 %).

CONCLUSIONS

Homicide-suicides are to some extent similar to simple couple homicides. Women are therefore overrepresented among domestic homicide victims; likewise, they are also overrepresented among the victims of homicide-suicides, which are mostly committed in family circumstances. The most significant risk factors are the presence of firearms in the household and history of domestic violence within the couple.

RECOMMENDATIONS

The results suggest two areas for action: the screening (interpersonal conflicts, alcohol, depression, domestic violence, presence of a firearm) and the prevention of intra-family homicides. Prevention should focus on screening specific elements: the presence of a firearm, domestic violence, interpersonal conflicts, depression, and alcohol. Prevention could also take place with elderly people at the end of their lives.

Homicide clearance in Western Europe

This study provides an overview of homicide clearance in four West European countries: Finland, the Netherlands, Sweden and Switzerland. Using data from the European Homicide Monitor, employing similar definitions and uniform coding schemes, this study allowed for unique cross-country comparisons in factors influencing differences in homicide clearance rates. Findings based on homicides occurring in the period 2009-14 revealed overall low homicide rates in all countries, with a wide variety in homicide clearance rates, ranging from 77 percent in the Netherlands to 98 percent in Finland. Results further showed that both event-based as well as victim-based characteristics significantly influenced the likelihood of homicide clearance, suggesting that homicide clearance rates can, for a large part, be attributed to the prevalent types of homicide in each of these European countries.

Homicide-suicide in Durban, South Africa

This study investigated homicide-suicide in Durban, South Africa, for the years 2000 to 2001. The incidence was 0.89 per 100,000, higher than the international average. A majority of perpetrators (91%) and victims (87%) were Black African, proportional to their representation in the population. Perpetrators were typically men (in 95% of cases), older than, and intimate partners (in 75% of cases) of the female victims (in 100% of cases). Average ages of perpetrators and victims were 32 and 27, respectively. The security sector was overrepresented as an employment category for perpetrators. A firearm was used in 87% of the homicides and 80% of the suicides. The individuals involved in homicide-suicides in Durban are similar to homicide-suicide perpetrators and victims in industrialized countries. The fact that homicide-suicides in South Africa, as in most countries, involve almost exclusively men killing female intimates confirms the importance of examining and challenging social norms enabling male violence against women.

Epidemiology of intimate partner homicide-suicide events among women of childbearing age in Maryland, 1994-2003

Intimate partner homicide-suicide (IPH-IPS) among women during the childbearing years leaves irreversible outcomes that are devastating and have lasting repercussions for surviving children, families, and communities. An estimated one-third of all intimate partner homicides of women aged 15 to 50 end in suicide. The purpose of this study was to describe the temporal trends and characteristics of both victims of IPH-IPS. Data were collected using a retrospective, cross-sectional analysis of medical examiner records for women aged 10 to 50 in Maryland, during 1994-2003. Seventy-five IPH-IPS incidents were identified over the 10-year period. Of those, 94.7% were a female homicide followed by a male suicide. The average rate of IPH-IPS was 0.52 per 100,000 women aged 10 to 50. About half of the couples were within 5 years of the age of each other, married or separated and the same race. Eleven percent of the women were pregnant/1-year postpartum when they died. The findings presented represent a significant public health problem that has a unique pattern compared with other populations studied. Understanding this problem involves a more comprehensive assessment of both victims. There is a need for a national surveillance system that identifies IPH-IPS events and provides information on both victims that includes individual and relationship characteristics.

The epidemiology of homicide followed by suicide: a systematic and quantitative review

This systematic review of population based studies of homicide followed by suicide was conducted to examine the associations between rates of homicide-suicide, rates of other homicides and rates of suicide. The review analysed 64 samples, including the case of an outlier (Greenland) that were reported in 49 studies. There was a significant association between the rates of homicide-suicide and those of other homicides in studies from the U.S.A. Outside the U.S.A. there was no clear association between homicide-suicide and other homicide but there was modest but significant association between rates of suicide and homicide-suicide. Homicide-suicide appears to be closer in epidemiological terms to homicide than suicide in regions with high rates of homicide and measures to reduce homicide in these regions may also reduce homicide-suicide.
