Critical elements in intimate partner homicides (IPH) often go undocumented. Previous studies have highlighted precipitating causes, but few have examined the place of injury that led to the victim's death. We sought to describe IPH cases in Illinois and in particular to examine factors surrounding the location of injury that led to the victim's death. We analyzed data collected in the Illinois Violent Death Reporting System to assess victim demographics, perpetrator characteristics, the victim/perpetrator relationship, and circumstances surrounding the location of injury that led to the victim's death. From 2005 to 2010, 275 cases were identified as IPH. Women comprised 60.4% of victims and men 39.6%. Among perpetrators, 78.5% were identified as male and 21.5% as female. Of the 31 corollary victims, 54.8% were less than 18 years and 58.1% were injured in front of a family member. Females were 1.6 times more likely to have the injury that led to their death occur at their residence, as compared to males (OR 1.6, 95% CI 1.1-2.9). Cases in which the perpetrator had documented history of abuse were 2.4 times more likely to have the fatal injury occur at the victim's residence compared to those that did not have previous history (OR 2.4, 95% CI 1.2-4.8). IPH cases in which the perpetrator was the current partner of the victim were twice as likely to have the injury leading to the victim's death occur at the victim's residence compared to those perpetrators who were not a current partner (OR 2.1, 95% CI 1.2-3.5). Considering the increased risk of IPH occurring at the place of residence for women at the hands of current intimate partners and by perpetrators with a previous history of abuse, prevention efforts may wish to prioritize in-home and relocation intervention strategies.

Post-mortem toxicology in violent fatalities in Cape Town, South Africa: A preliminary investigation

Problem/Condition: In 2020, approximately 71,000 persons died of violence-related injuries in the United States. This report summarizes data from CDC's National Violent Death Reporting System (NVDRS) on violent deaths that occurred in 48 states, the District of Columbia, and Puerto Rico in 2020. Results are reported by sex, age group, race and ethnicity, method of injury, type of location where the injury occurred, circumstances of injury, and other selected characteristics. Period Covered: 2020. NVDRS collects data regarding violent deaths obtained from death certificates, coroner and medical examiner records, and law enforcement reports. This report includes data collected for violent deaths that occurred in 2020. Data were collected from 48 states (all states with exception of Florida and Hawaii), the District of Columbia, and Puerto Rico. Fortysix states had statewide data, two additional states had data from counties representing a subset of their population (35 California counties, representing 71% of its population, and four Texas counties, representing 39% of its population), and the District of Columbia and Puerto Rico had jurisdiction-wide data. NVDRS collates information for each violent death and links deaths that are related (e.g., multiple homicides, homicide followed by suicide, or multiple suicides) into a single incident. For 2020, NVDRS collected information on 64,388 fatal incidents involving 66,017 deaths that occurred in 48 states (46 states collecting statewide data, 35 California counties, and four Texas counties), and the District of Columbia. In addition, information was collected for 729 fatal incidents involving 790 deaths in Puerto Rico. Data for Puerto Rico were analyzed separately. Of the 66,017 deaths, the majority (58.4%) were suicides, followed by homicides (31.3%), deaths of undetermined intent (8.2%), legal intervention deaths (1.3%) (i.e., deaths caused by law enforcement and other persons with legal authority to use deadly force acting in the line of duty, excluding legal executions), and unintentional firearm deaths (<1.0%). The term "legal intervention" is a classification incorporated into the International Classification of Diseases, Tenth Revision, and does not denote the lawfulness or legality of the circumstances surrounding a death caused by law enforcement. Demographic patterns and circumstances varied by manner of death. The suicide rate was higher for males than for females. Across all age groups, the suicide rate was highest among adults aged ≥85 years. In addition, non-Hispanic American Indian or Alaska Native (AI/AN) persons had the highest suicide rates among all racial and ethnic groups. Among both males and females, the most common method of injury for suicide was a firearm. Among all suicide victims, when circumstances were known, suicide was most often preceded by a mental health, intimate partner, or physical health problem or by a recent or impending crisis during the previous or upcoming 2 weeks. The homicide rate was higher for males than for females. Among all homicide victims, the homicide rate was highest among persons aged 20-24 years compared with other age groups. Non-Hispanic Black (Black) males experienced the highest homicide rate of any racial or ethnic group. Among all homicide victims, the most common method of injury was a firearm. When the relationship between a homicide victim and a suspect was known, the suspect was most frequently an acquaintance or friend for male victims and a current or former intimate partner for female victims. Homicide most often was precipitated by an argument or conflict, occurred in conjunction with another crime, or, for female victims, was related to intimate partner violence. Nearly all victims of legal intervention deaths were male, and the legal intervention death rate was highest among men aged 35-44 years. The legal intervention death rate was highest among AI/AN males, followed by Black males. A firearm was used in the majority of legal intervention deaths. When a specific type of crime was known to have precipitated a legal intervention death, the type of crime was most frequently assault or homicide. When circumstances were known, the three most frequent circumstances reported for legal intervention deaths were as follows: the victim's death was precipitated by another crime, the victim used a weapon in the incident, and the victim had a substance use problem (other than alcohol use).

The toxicological findings from 6037 analyses of viscera obtained from victims of traumatic death are used to correlate the relative incidence of carbon monoxide, ethyl alcohol, narcotics, hypnotics, analgesics, and tranquilizers-antidepressants in deaths occurring under the following circumstances: fire related, asphyxia by hanging, by use of plastic bags, from physical obstruction of trachae, and by drowning; traumatic injury from impact of moving train, fall from height, and occupational accident; traumatic injury to pedestrian, driver, and passenger from vehicular accidents; and from violent death by shooting, stabbing, strangulation, and beating. The influence of alcohol, narcotic drugs, and tranquilizers on carbon monoxide can be seen in some of these traumatic deaths. Ethanol alone and in combination with other drugs was present in 42.3% and 19.5% of driver and pedestrian victims, respectively, of vehicular accidents in the year 1974. Comparative analysis is presented for the toxicological data obtained on victims of homicide (shooting, stabbing, strangulation, and beating) in New York City and similar data reported for victims of homicide in Detroit. In New York City 45.9% of such victims died while under the influence of alcohol or narcotic drugs, or both, with methadone predominating in the latter category. Tissue concentrations of drugs found in victims of traumatic death are presented. Diphenylhydantoin, diazepam, meperidine, and slow-acting barbiturates were found in normal therapeutic levels. Higher concentrations of amitriptyline, chlorpromazine, propoxyphene, short-acting barbiturates, and methadone were observed. The concentration of methadone in blood and brain (0.13 +/- 0.14 mg/100 ml) and in liver (0.53 +/- 0.42 mg/100 ml) in cases of traumatic death are not different from those observed in deaths classified as due to methadone overdose.

BackgroundAtherosclerosis is the leading cause of coronary heart disease and ischemic stroke, which can cause sudden death in adulthood. In general, the clinical manifestations of cardiovascular diseases are caused by atherosclerosis, which is a process that starts during middle age. More recent studies indicate that the atherosclerotic process begins during childhood.MethodsTo evaluate the extent of atherosclerotic disease in young Brazilians, we conducted a study of the pathological alterations in the major arteries of victims of violent death. Samples of the right carotid artery, left coronary artery, and thoracic aorta of young victims of violent death were analyzed and graded in accordance with the histological atherosclerotic lesion types proposed by the American Heart Association. Samples were collected from 100 individuals who had died from external causes, aged from 12 to 33 years.ResultsThe majority of cases (83%) were male, and 66% of deaths were homicides caused by firearms. The median age was 20.0 years and mean body mass index was 20.9 kg/m2. Of the right carotid artery specimens, 3% were normal, 55% had type I, 40% had type II, 1% had type III, and 1% had type IV atherosclerotic lesions. Of the left coronary artery specimens, 5% were normal, 48% had type I, 41% had type II, 3% had type III, and 3% had type IV lesions. Of the thoracic aorta specimens, none were normal, 13% had type I, 64% had type II, 22% had type III, and 1% had type IV lesions. Overall, 97.34% of arteries examined had some degree of atherosclerosis. The most common histological type was type II (foam cells). No thoracic aorta specimens were normal, and the coronary artery specimens had the most atherosclerosis.ConclusionsOur results show a high prevalence of atherosclerotic lesions among young people in Brazil. Intervention should be undertaken to decrease the rate of sudden cardiac death in the adult population.

The medical diagnoses and frequency of emergency department visits made by children who are later given a diagnosis of maltreatment do not differ much from those of nonabused children. However, the type of medical complaints and frequency of emergency medical services (EMS) use by child homicide victims before their death are not known. We compared EMS use between child homicide victims and children who died from natural causes before their death. This was a retrospective case-control study of children 0 to 5 years old who died in Houston, Texas, from 2005 to 2010. Cases were child homicide victims. Controls were children who died from natural causes. We reviewed death data and EMS and child protective services (CPS) encounter information before the victim's death. The association between death type (natural vs homicide) and EMS use was assessed using Poisson regression with EMS count adjusted for exposure time. There were 89 child homicides and 183 natural deaths. Age at death was significantly higher for homicides than natural deaths (1.1 vs 0.2 y, P < 0.001). Homicide victims used EMS services (39% vs 14%, P < 0.001) and had previous CPS investigations (55% vs 7%, P < 0.001) significantly more often than children who died from natural causes. Poisson regression, after adjustment for age, revealed that the homicide group had more EMS calls than the natural death group (β = 0.55; 95% confidence interval, 0.04-1.07; P = 0.03). However, the EMS use frequency and working assessments were not helpful in identifying maltreatment victims. Child homicide victims use EMS more often and have a higher number of CPS investigations before their death than children who die from natural causes. However, the frequency and nature of EMS medical complaints are not helpful in identifying maltreatment.

Victims of homicide and attempted homicide are not uncommon in Sweden. We therefore aimed to study these victims to understand their injuries, their cause of death, and their relationship to the offender. All cases during five years in a district court in Sweden, where an offender had been convicted for homicide or attempted homicide, were identified and the court documents reviewed. Nineteen victims were identified; 14 males and five females, with an average age of 39.1 years. Although knife/sharp weapon was the most common weapon used, the use of firearm caused more deaths. Our study shows higher rates of firearm use than many other countries. The most common anatomical site to be injured by knife/sharp weapon and firearm was the thorax followed by the head. The most common cause of death was hypovolemia, followed by intracranial injuries. The high rate of firearm use shows that firearms are common modus operandi in Sweden often causing lethal injuries, if the offender intends to kill the victim. Our results support other studies showing that it is foremost injuries to the vessels, intracranial injuries, and injuries to intrathoracic organs, which causes a victim's death when assaulted with knife/sharp weapon or firearm.

Violent Deaths Among Georgia Workers: An Examination of Suicides and Homicides by Occupation, 2006-2009.

Background: The National Violent Death Reporting System (NVDRS) is a state-based surveillance system that collects information and tracks violent deaths in all fifty states, the District of Columbia, and Puerto Rico. Methods: Louisiana collected data in 2017 in four parishes: Orleans, Jefferson, East Baton Rouge, and Calcasieu. Data presented here are from the 2017 pilot year. Data on violent deaths were collected from law enforcement reports, coroner reports, and death certificates. Violent deaths included homicides, suicides, deaths of undetermined intent, accidental firearm deaths, and legal intervention deaths. Results: In 2017 in Orleans, Jefferson, East Baton Rouge, and Calcasieu Parishes there were 644 victims of violent deaths: 351 homicides, 231 suicides, 47 undetermined deaths, 6 legal intervention deaths, and 9 accidental firearm deaths. Conclusion: The comprehensive information collected by NVDRS will enable program and community partners to develop violence prevention efforts.

Background: Excessive alcohol consumption is a serious public health issue, because drunkenness affects critical judgment and self-control, making people more vulnerable to violence and accidents, with thus a potential association between alcohol consumption and violent deaths. Objective: To assess the association between alcohol consumption and violent deaths in the city of Sao Paulo, Brazil, in 2015, and its relationship with gender, age, cause of death and blood alcohol concentration (BAC) of victims. Methods: A cross-sectional retrospective study was conducted by collection of data from 2,882 victims of violent deaths subjected to examination of BAC from the archives of the Institute of Legal Medicine of the State of Sao Paulo, Brazil. Results: Alcohol was detected in blood samples of 27.06% of the victims and mean BAC levels were 1.92 ± 1.24 g/L. The mean age of the victims was 33.49 ± 15.19 years. The majority of the victims were male (84.14%) and the prevalence of positive BAC was higher amongst men (28.74%) than women (18.16%). Homicide was the most prevalent cause of death in the sample (36.57%), but there were a higher proportion of traffic accidents victims with positive BAC (32.01%), as well as higher BAC levels in these victims (46.77% in the range of 1.6–2.5 g/L). Conclusions: The results obtained in this study support a potential association between alcohol consumption and violent deaths in the city of Sao Paulo, mainly in traffic accidents victims.

In Finland, the high rates of forensic autopsy and postmortem toxicology furnish a reliable base for nation-wide studies on alcohol-related violent deaths. National mortality and population data within Finland, from 1987 to 1996, were used to analyze sex- and age-specific rates, proportions, and trends of violent deaths associated with alcohol. Deaths were defined as alcohol-related when alcohol was certified as a contributing factor to death. During the study period, 10,360 (23.3%) of the 45,544 violent deaths that occurred were alcohol-related. Among 15- to 64-year-olds, 28.6% of accidents, 30.5% of suicides, and 55.3% of homicides were associated with alcohol (alcohol-positive). Differences in epidemiologic patterns and trends for different types of violent death were observed between sexes and age groups. For instance, alcohol-positive accidents significantly decreased in males (-2.3%/year; CL95: -3.3, -1.2; p < 0.001), but not in females (+0.5%/year; CL95: -2.7, +3.7; p = 0.772), and alcohol-positive suicides increased slightly in females (+3.9%/year; CL95: +0.0, +7.9; p = 0.047), but not in males (-0.2%/year, CL95: -1.4, +1.0; p = 0.704). The victims of violent deaths have often consumed or abused alcohol before the fatal events. Especially in young adults, consumption of alcohol is likely one of the most serious risk factors in accidents and may decrease the threshold for suicide ideation and impulsive behaviors. Studies that explore the effects of sociodemographic and health factors on random populations with relevant control data will increase the understanding of the causal connection between alcohol and violent deaths.

Women, while noted for low occupational injury mortality rates, are more likely to die as victims of assault than from any other manner of injury at work. From the National Traumatic Occupational Fatality surveillance data, 950 women were identified who were fatally assaulted at work. Homicide rates were calculated for the demographic and employment characteristics of these women. Risk ratios among types of lethal injuries were examined. During 1980-1985, the crude six-year workplace homicide rate was 4.0 deaths per million working women: one twentieth the homicide rate of the US female population. Decedents ranged from 16 years (the lowest age included in the data base) to 93 years of age. Working women older than 65 years had the highest age-specific homicide rate, 11.3 per million. Women younger than 20 had the lowest, 2.5 per million per year. Homicide rates for women of races other than White were nearly twice as high as those of Whites. The leading causes of death were gunshot wounds (64 percent), stabbings (19 percent), asphyxiations (7 percent), and blunt force trauma (6 percent). Nearly 43 percent of the deceased women had been employed in retail trade: 8.7 per million employed women annually. During 1980-1985, only 6 percent of the nation's victims of work-related injury deaths were female: 41 percent of those women were murdered. Homicide is currently the leading manner of traumatic workplace death among women in the United States.

BackgroundLimited information is known about the impact of childhood maltreatment on lifetime risk of violent death. This study aimed to compare manner of death, demographics, age at time of death, and the presence of a mental health or substance use disorder among decedents of violent deaths with a history of child maltreatment to those without.MethodsThis cross-sectional study compared characteristics of pediatric and adult violent deaths with and without a history of child maltreatment that were captured in the National Violent Death Reporting System from 2014 through 2018.ResultsDecedents who were male, multiracial, and had adulthood substance or mental health disorders were more likely to have a history of maltreatment. All-age decedents with a history of maltreatment were more likely to die by homicide. Adult decedents with a history of maltreatment were more likely to die by suicide. Maltreated decedents died significantly younger than non-maltreated decedents.ConclusionsAmong victims of violent deaths, an identified history of child maltreatment was associated with increased risk of homicide across the lifespan, adult suicide, and earlier death. A history of child maltreatment was also associated with mental health and substance use disorders, which may reflect one of the pathways through which the child maltreatment-to-death association functions.

Introduction: The tendency to impulsive behaviors and/or violence is exacerbated after alcohol consumption. Still, the relation between alcohol/violent deaths reported in the literature is not accurate, and in general, alcohol is only seen as a trigger to aggressive actions. The relationship of the victims with their blood alcohol is less studied. They were especially concerned about the role of alcohol as a risk factor for victims of unnatural death. Thus, our goal is to check the influence of alcohol in victims of violent deaths as homicides, suicides, and accidents. Materials and methods: Retrospectively the medical records of 805 autopsies performed at the Institute of Forensic Medicine (IML) of Franco da Rocha, in the period 2001 to 2017 were reviewed. The variables studied were sex, age, types of violent death rates, and alcohol - these were considered positive when above 0.3 mg/ml. The dosage of blood alcohol concentration (BAC) was performed using samples of 10 ml of blood collected at necropsy, is preferably taken from the cardiac chambers or of the right femoral vein. Dosages of alcohol in blood samples were done in the Forensic Toxicology Center of the IML by gas chromatography, using the technique of separation “headspace” and double column. Results: Drug testing for alcohol was available for 488 (79.1%) of 617 necropsies. Of the 617 subjects studied, 532 (85.7%) were male, and 85 (13.8%) were females (with high rates of adolescents). The vast majority (n = 230) were killed, and 40.5% of victims had BAC above 0.3 mg/ml of blood. Traffic accidents came next, accounting for 181 deaths, with 41% of victims presenting positive BAC. Discussion: High blood alcohol levels of the victims were associated mainly with the genesis of accidents (drowning, falls, traffic, aspiration/ smothering) and murder (with impaired ability to resist or by causing the release of impulses to engage in violent situations), about 40% of cases. Conclusion: Our results indicate that alcohol abuse is a risk factor for victims of violent death. In these cases, alcohol has two types of action. Direct: contributes to accidents of various kinds - from traffic by decreasing powers of concentration, attention, and loss of reflexes, to other types of accidents such as drowning, falls, swallowing disorders causing airway obstruction, and mechanical asphyxia. And they were indirect, making it easier for individuals to engage in conflict (and thus become victims of crimes).

Incidence of female homicide in the Transkei sub-region of South Africa (1993–2015)
