Injuries inflicted on homicide victims: A longitudinal victiminologic study of lethal violence

For the purpose of studying homicidal violence from a victiminologic point of view, we have examined the number and nature of injuries inflicted on homicide victims examined at the Department of Forensic Medicine in Stockholm during the periods 1976–1978, 1986–1988 and 1996–1998. Evaluation of the total number of injuries (both lethal and non-lethal) revealed a break in the earlier trend during the last of these periods, which demonstrated a clear increase in the number of injuries probably caused by intense and prolonged violence. Thus, there were 14 victims with 40 or more injuries (the maximum being 101 injuries) in the 1996–1998 period, whereas there was only one such victim in each of the two earlier periods. Furthermore, the proportion of victims exhibiting multiple lethal injuries was greater during the last period than during the two preceding periods. These findings indicate a general enhancement in the level of aggression exerted by violent offenders, as well as an increase in the number homicide victims with injuries apparently inflicted by acts of aggression characterized by outrage.     

Homicide victim/offender relationship in Florida Medical Examiner District 8

This study examined the correlations between victim/offender relationship and three variables: motive, weapon choice, and number of injuries inflicted. Empirical relationship and motive categories were used. The sample consisted of 57 intentional homicide cases from Florida Medical Examiner District 8 between the years 1992 and 1996. Relationships were divided into primary and secondary categories. Primary relationships included intimates, relatives, and friends; secondary relationships included acquaintances and strangers. Motives were classified as romantic dispute, argument/conflict, revenge, or felony type; weapons as firearm or contact; and number of injuries inflicted as single or multiple. A significant correlation was found between victim/offender relationship and homicide motive; however, the revenge and felony type motive categories did not differ. Unexpectedly, no correlation was found between victim/offender relationship and either weapon choice or number of injuries inflicted. Further study is needed of the interactions between homicide victim/offender relationship and motive, weapon selection, and number of injuries inflicted.     

Examination of live victims of violent crimes at the Institutes of Legal Medicine of Hanover, Cologne and Leipzig

During the last few years the importance of clinical forensic medicine has increased within the field itself, but also in interdisciplinary cooperation. Although examinations of live victims play a substantial role in the every-day work of most German forensic scientists, the number of data published on their frequency and the type of offence for which they were performed is small. For this reason a comparison of the data from the Institutes of Legal Medicine in Hanover, Cologne and Leipzig was carried out. Most of the examinations performed by all the three institutes were ordered by courts, the prosecution or the police. Only in a few cases did private persons or hospitals ask for a forensic expert opinion on injuries. During the study period the total number of examined violence victims per annum increased noticeably from 252 in 1999 to 507 in 2003. The total number of examinations during the five-year study period amounted to 1181 in Hanover, 393 in Leipzig and 198 in Cologne, which all have a similar number of inhabitants in the respective catchment area of the institutes. Most of the examinations were carried out in victims of bodily harm, sexual assault and child abuse, but also in traffic offences, for age determination, in self-inflicted injuries and in suspects of homicide. On the one hand the remarkable rise of the number of physical examinations shows that the importance of forensic expert opinions is increasingly recognized. On the other hand the considerable regional differences demonstrate that the competence offered by the Institutes of Legal Medicine in the documentation and interpretation of violence is by far not yet sufficiently used.     

Association between homicide injury severity and benzodiazepine influence

There are case reports of offenders inflicting excessive injuries on their victims when under the influence of benzodiazepines. However, the potential association between benzodiazepine influence on the offender and victim injury severity in a general homicide population has not been studied. We investigated associations between offender positive testing for benzodiazepines or z-drugs (zolpidem, zopiclone and zaleplon) and victim injury severity. Data were drawn from 95 Swedish homicide cases from 2007–2009 in which offenders had known toxicology. There were no significant differences in injury severity between cases in which the offender tested positive vs. negative for benzodiazepines/z-drugs. Thus, the findings do not support the hypothesis that there is an association between benzodiazepine influence on the offender and victim injury severity in a general homicide population.

Key points

• Some previous studies have linked benzodiazepines to aggression, violence and excessive homicide injuries.
• The present study analysed the association between homicide injury severity and benzodiazepine status of the offender.
• Offenders who tested positive for benzodiazepines did not inflict more severe injuries on their victims.
• These findings do not support the hypothesis that benzodiazepine influence generally causes offenders to inflict more severe injuries on homicide victims.

     

Comparing Women and Men Arrested for Domestic Violence: A Preliminary Report

This study uses criminal justice data to compare women and men arrested for domestic violence on their levels of violence, reported victimization, general criminality, and substance abuse. Participants were 45 women and 45 men convicted of domestic violence between 1996 and 1998. Results indicate that women were less likely than men to have a history of domestic violence offenses and nonviolent crimes. They were also more likely to report that they had been injured or victimized by their partner at the time of their arrest. However, in other ways, women and men were similar: they were equally likely to have used severe violence and inflicted severe injuries on their victims; to have previously committed violence against nonintimates; and to have been using drugs or alcohol at the time of their arrest. The implications for treatment for women arrested for domestic violence are discussed.     

Fighting back: Lethal responses to predatory attacks

Each year millions of Americans become victims of predatory crimes. The way victims respond to these attacks varies from complicance with offenders' requests to physically challenging offenders. In some cases, the physical defense of self and property has lethal consequences for the initial offender. While much is known about felony murder victims and typical homicide offenders, little is known about individuals who fight back against predatory attack by using lethal violence. In this paper, we use data from the Homicides in Chicago, 1965–1995 study to describe the characteristics of defensive homicide offenders and to determine how they compare with felony murder victims and defensive homicide offenders. Our results indicate that defensive homicide offenders are more similar to typical homicide offenders than felony murder victims, and are even more likely to have violent criminal histories and to use firearms than typical homicide offenders. Our results challenge the common perception that individuals who fight back against predatory attack are simply “law-abiding citizens.” We conclude the paper with a discussion of the implications of our study for additional research and police practice.

A forensic medicine perspective on recurring episodes of intimate partner violence

During a three year period, 418 victims of intimate partner violence (IPV) were examined and their injuries documented at the Center for Victims of Violence (CVV) in Hamburg, Germany. All victims were questioned if their acute injuries were attributable to recurring acts of violence by the same intimate partner. The victims' experiences with recurring IPV were analyzed and associated risk factors as well as findings of acute physical injuries were integrated into the assesment. Overall, women were significantly more often victims of recurring episodes of IPV than men. In 35.4% of cases, victims of recurring IPV sustained injuries to three or more body regions. However, women who were victimized during a single act of violence, presented with the same distribution of injuries in only 21.1% of cases (p = 0.01). The results emphasize the fact that IPV often manifests itself in a spiraling escalation of physical violence. Furthermore, blunt force trauma to the head was diagnosed significantly more often (p = 0.05). The risk of sustaining a head injury was equally high for women who experienced a first-time violent episode by their ex-partner as it was for married women or women living in a non-marital partnership during recurring episodes of IPV. In an effort to reduce the increased risk for victims of IPV, health care personnel are highly encouraged to partake in forensic medicine based continuing education. This preventative measure may prepare clinicians to recognize IPV earlier as well as to treat and advise clients appropriately.     

Homicide in Adana, Turkey: a 5-year review

Violence is a significant public health problem. Thus, so as to prevent this problem, homicide, the severest form of violence depriving a human being of his right to live, deserves a detailed examination. This study is a retrospective research examining the 2951 cases of medicolegal autopsies in Adana during a period of 5 years (1997-2001). Among these cases, 620, which were determined to be homicidal, were taken into the scope of this study. The cases were examined with respect to sex, age groups, the method used during the act of homicide, the number and the localization of the wounds on the body. A total of 620 (21%) of the medicolegal autopsies conducted within this period were homicides. Of these cases, 515 (83.06%) were male and 105 (16.94%) female, and the rate of the males to females was 4.9; 72.74% of the victims were between the ages of 21 and 50. It was seen that 54.83% of the homicides involved firearms, while 35.16% of the victims were stabbed to death with a cutting object. It was also determined that the victims suffered a single wound in 47.35% of firearm-related murders and 29.35% of stabbings resulted in death. Alcohol was found in the blood of 7.58% of the homicide victims, while none had any illicit drugs.     

Variations in wounding by relationship intimacy in homicide cases

There are numerous examples in the homicide literature of a presumed connection between the victim-offender relationship and the manner, extent, and body location of wounds inflicted in homicides. The current study examined variations in wounding patterns according to the intimacy of the victim-offender relationship in a sample of urban homicides to explore the investigative utility of this information in an average homicide event. The findings demonstrated that victims who had a current or former intimate relationship with their offender were more likely to receive wounds to the face and be injured with a weapon from the scene compared with all other relationship groups, whereas injury to the head and use of manual violence were more likely among intimates and family/friends compared with acquaintances or strangers. However, the groups did not significantly differ in terms of the overall amount of wounds inflicted. Implications of the findings and suggested areas of future research are discussed.     

Bimodal distribution of violent assaults

The aim of the present study was to investigate the relationship between the number of injuries inflicted on victim during violent assault and other variables, characterizing the offender and the assault. The study is based on all the cases that were processed at the City Court of Tallinn, Estonia in 1986 and 1996. The number of assault-related injuries caused to the victim in Tallinn, Estonia, for 1986 and 1996 revealed bimodal distribution. About 2/3 of the assaults resulted in 1-5 injuries, in 1/3 of the cases the number of inflicted injuries was 10 or higher, with only a relatively small number of injuries in between. This distribution pattern was stable over the 10-year interval between the observations and was invariant to alcohol intoxication, consequences, and reasons for the assault. Comparison of the offenders' criminal record during the 15-year follow-up period showed that recidivism was more common among those who had committed a multi-injury assault as their first offence. The evident distribution of assaults into few- and multi-injury groups and the fact that the number of injuries caused during the first offence is a more reliable criterion for predicting the further criminal record of the offender than the consequences of the assault suggest that there are two discrete types of behaviour determined by a set of variables characteristic of the offender's psychology.     

Sharp Force Homicide in Denmark 1992–2016

Sharp force trauma is a common homicide method. The weapon is typically a knife, which is easily accessible and does not require special skills. We have analyzed all 471 sharp force homicides in Denmark during 1992–2016 with special focus on aspects that are relevant to forensic pathologists, including the distribution of wounds and organ injuries. Most homicides were committed inside with a kitchen knife. The front left thorax was the most common area to be affected by sharp force trauma. In 18.9% of the victims, there was only one sharp injury, the majority on the thorax. The most common trajectory for stab wounds was directly posterior with no deviation to the sides or up/down followed by directly anterior. The heart (including pericardium) and lungs (including hemo- and pneumothorax) had injuries in more than 75% of the victims. 67% of victims were males. Female victims had more sharp force injuries and defense wounds than male victims. Most females were killed in domestic homicides (73.7%), most commonly in partner killings (56.4%). In contrast, many male victims were killed in a setting of nightlife/intoxication (34.0%) most by a friend/acquaintance delivering a few stab wounds. The results clearly show strong sex differences in both victims and offenders. This could be useful for shaping policies and public opinion, and as a route for understanding the developments in interpersonal violence. In the narrow setting of death investigation, our results will provide an evidence-based approach to understanding the injury patterns in sharp force homicide.     

Pedicide revisited. The slaughter continues

Pedicide, a reliable indicator of interpersonal violence and severe child abuse, has risen in Cuyahoga County (Metropolitan Cleveland), Ohio, U.S.A., over the past quarter of a century, paralleling or exceeding the increase in adult homicide. However, neonaticides have decreased, a phenomenon mirroring a marked fall in fatal maternal criminal abortions. As previously noted, modalities of lethal violence in pedicide are significantly determined by victim age. An increasing proportion of pedicide victims, like their adult counterparts, have been killed by firearms. Pedicide victims are much apt to be killed by close relatives than are adult homicide victims. Similarly, perpetrators of pedicide are much more likely to commit suicide than are their adult-slaying counterparts. Fatally "battered" children, the victims of multiple, metasynchronous traumata, represent a significant fraction (22%) of the overall pedicide population and constitute a segment of the victims with a potential for being saved by intervention. Overall, pedicide remains a challenge to our profession and a threat to society as a whole.     

Child and elderly victims in forensic autopsy during a recent 5 year period in the southern half of Osaka city and surrounding areas

To outline the recent features of child and elderly victims from the medico-legal perspective with special reference to abuse and neglect, a retrospective investigation of forensic autopsy cases over a 5 year period (1994-1998) in the southern half of Osaka city and surrounding areas (a population of 1.57 million) was undertaken. Among 646 autopsy cases, there were 53 child cases (under the age of 15 years, about 80% below 6) and 121 elderly cases (65 years old and above). Nearly half of the child deaths and more than half of the elderly deaths were described as accidental. Fire and traffic victims were much more frequent in the elderly. Child victims included those of neonaticide/infanticide (n=6), physical abuse (n=10), unintentional fatal infliction (n=2), neglect (n=2), mutual suicide (n=2), suicide (n=1) and murder (n=3). Child abuse and neglect were domestic maltreatment by the parents. In this series, there was a comparable number of fatalities due to maltreatment in the elderly (n=13) and in children, and non-domestic violence was more frequent in the elderly than domestic violence. Elderly females tended to be battered by their sons or grandsons in domestic violence cases, whereas males were predominantly attacked by younger males in non-domestic violence. The other elderly victims included those of self-neglect (n=2), murder (n=7) and suicide (n=9). Non-domestic homicide of the elderly occurred mainly in the center of the city, whereas domestic maltreatment of children and the elderly was sporadic, although somewhat more frequent in the peripheral zone of the city and the surrounding areas. The above profile of child and elderly abuse suggests a substantial influence of social and familial backgrounds.     

The many faces of violence: A theoretical and statistical comparison of homicides,suicides, and motor vehicle fatalities

Homicide as a form of lethal violence has occupied a dominant place in criminological research over several decades. Researchers have explained the causes of homicide from various theoretical frameworks. Two other forms of lethal violence, namely suicide and motor vehicle fatalities, have been largely ignored. This study explores the trends in three forms of violent deaths namely, homicide, suicide, and motor vehicle fatalities in Phoenix, Arizona for the period 1950–1988. These three forms of violence have been tested from two dominant theoretical perspectives, namely social disorganization and social conflict. The findings from our study suggest that the social conditions which influence homicide are the same as those that influence other forms of lethal violence.     

Women who kill: a comparison of the psychosocial background of female and male perpetrators

The purpose of this study was to compare the psychosocial background of female and male perpetrators convicted of homicide in Sweden between 1995-2001. All women (n=43) who were convicted for lethal violence during the period and a corresponding number of randomly chosen men (n=43) were examined. In total, information about 86 individuals was collected retrospectively. Areas of interest were psychosocial variables during childhood and at the time of the current crime. Results showed that both female and male perpetrators were psychosocially encumbered already at an early age. Homicidal women had more severe childhood circumstances, but less aggressive childhood behaviour than did their male counterparts. At the time of the crime, women had a more ordered social situation, had more often been exposed to violence and searched for help than had the men. These gender differences suggest that specific actions are needed for preventing women's homicidal behaviour.     

Criteria for homicide and suicide on victims of extended suicide due to sharp force injury

This report is about the findings in association with the extended suicides of nine victims killed by sharp force. All victims were killed by sharp force. The perpetrators were predominantly the parents, the victims their children. Regarding the criteria for differentiating self-inflicted injuries from injuries inflicted by another person, the victims' injuries presented patterns usually found solely in suicides. Thus eight of nine cases presented tentative and hesitation injuries, in three of five cases areas of injury covered by clothing had been exposed beforehand. Despite extremely narrow intercostal spaces in children, injuries to the bones in thoracic stabbing were avoided more often than not (four of seven cases). Only the criterion "defence injury" occurred nearly as often as in homicide victims (three of nine cases). The psychopathology of extended suicide can explain this pattern. The perpetrator's motive is characterised by his pseudoaltruistic belief to save the loved ones from a world that is in his opinion unacceptable. A fusion or integration of the victim into the perpetrator's own self is based on an identity problem. Physical interrelation of forces between perpetrator and victim restricts the victim in his defence and presents an important prerequisite for acquiring the patterns of described injuries.     

Injuries due to deliberate violence in areas of Denmark. I. The extent of violence

As part of a transcultural investigation of violent behavior in Denmark and South America an analysis was made during a one year period of the incidents involving deliberate violence as registered at 3 Danish emergency wards, and at the Institute of Forensic Medicine in Copenhagen. In the three emergency wards a total of 1316 victims of deliberate violence were observed corresponding to a rate of about 3.3/1000 per year in a provincial/rural district, the catchment region of Holbaek County Hospital, 5.5/1000 per year in a mainly middle income area of the metropolis Copenhagen, the catchment region of Frederiksberg Hospital, and 7.6/1000 per year in a mainly low income area of Copenhagen, the catchment region of the Rigshospital. The highest risk, 28/1000 per year, was found for young men between 15 and 19 years of age living in the low income area of Copenhagen. The risk was low for people greater than or equal to 60 years of age in all three areas investigated, ranging from 0 (men) to 1.3/1000 per year (women). Skilled and unskilled workers were greatly over represented as victims of violence, considering their share of the background population. Seventy percent of the victims were men. At least 44% of the men and 32% of the women were alcohol intoxicated when arriving in the emergency ward. The incidents took place in restaurants or in the vicinity of restaurants for 30% of the male and 11% of female victims respectively, while 45% of the women had been subject to deliberate violence at home. The rate of fatal cases of deliberate violence in the Eastern part of Denmark, the catchment area for the Institute of Forensic Medicine in Copenhagen, was found to be 0.02/1000 per year. The risk of becoming a victim of deliberate violence has not increased during the last 4 years comparing with similar investigations from other parts of Denmark. However, the rate of homicide seems to have increased, and so has the severity of the injuries caused by deliberate violence. The pattern of deliberate violence appears to be associated with socio-economic and cultural factors, and to be closely linked with alcohol intoxication.     

Exposure Reduction or Retaliation? The Effects of Domestic Violence Resources on Intimate‐Partner Homicide

Rates of homicide involving intimate partners have declined substantially over the past 25 years in the United States, while public awareness of and policy responses to domestic violence have grown. To what extent has the social response to domestic violence contributed to the decline in intimate‐partner homicide? We evaluate the relationship between intimate‐partner homicide and domestic violence prevention resources in 48 large cities between 1976 and 1996. Controlling for other influences, several types of prevention resources are linked to lower levels of intimate‐partner homicide, which we interpret in terms of their capacity to effectively reduce victims' exposure to abusive or violent partners. Other resources, however, are related to higher levels of homicide, suggesting a retaliation effect when interventions stimulate increased aggression without adequately reducing exposure. In light of other research on deficiencies in accessing and implementing prevention resources, our results suggest that too little exposure reduction in severely violent relationships may be worse than none at all.     

Homicide‐Suicide in Konya,Turkey Between 2000 and 2007*

Abstract: Homicide followed by the suicide of the murderer is a relatively rare lethal incident in which an individual kills another person and subsequently dies by suicide. Cases involving a homicide and a suicide in which death examinations and autopsies were performed at The Konya Branch of the Forensic Medicine Council between 2000 and 2007 were retrospectively investigated. During the studied time period, there were 10 homicide‐suicide cases identified with 10 perpetrators killing 12 victims. Nine of the perpetrators were men and eight of the victims were women. The precipitating motive was an impending divorce in four of the cases. Two perpetrators were described as severely depressed, one had a diagnosis of antisocial personality disorder, and one was a pedophile who had reactive depression. Firearms were used in eight of the homicide cases and seven of the suicides. Constricting the use of firearms may reduce/prevent future homicide‐suicide cases, as it is the most commonly used method to carry out homicide‐suicides.
