On tackling abuse of older people: The forensic challenges in fatal cases investigation

The World Health Organization recently presented the priorities for tackling abuse of older people in a coordinated and strategic way. However, data on the forensic scenario is still lacking. In this context, the aim of the present work was to provide a comprehensive literature review of this inherently complex phenomenon in the post-mortem setting, in order to better characterize it from a forensic point of view. A comprehensive literature search was performed in three electronic databases following the PRISMA guidelines. Sociodemographic and medical data of victims and perpetrators, post-mortem data, types of abuse and risk factors were extracted from non-aggregated data. Forty-eight papers dealing with abuse in the post-mortem setting were included, with a predominance of case reports and case series. The review showed that neglect was the most common type of abuse and victims are predominantly older women who are abused in a domestic setting by trusted family member. To generate more and better data, expanded research in the forensic field requires standardized methods and the raise of professional awareness about abuse of older people.

A population-based cross-sectional study examining homicides among community-dwelling older adults in Victoria, Australia: A study protocol

BACKGROUND

There is a need for both descriptive and analytical evidence on the factors associated with older adult homicide. The current landscape is insufficient because most published research is confined to the United States, and contains insufficient data about the homicide context. This study protocol describes the proposed method for examining the characteristics and factors associated with older adult homicide in the Australian state of Victoria, using data generated for the criminal and coronial investigation into these deaths stored in the Victorian Homicide Register (VHR). Outcomes will support practitioners, policy makers and other key stakeholders to strengthen prevention strategies to reduce the risk of future homicides among older Victorians.

METHODS

This study will comprise a single-jurisdiction population-based cross-sectional design to analyse consecutive cases of homicide among community-dwelling older adults in Victoria, Australia for the period 2001 to 2015. All homicides of adults aged 18 years and older, and where the Coroner's investigation is completed at data extraction will be included. Variables will be selected in accordance with elements of the social-ecological model (i.e., individual, interpersonal, incident, and community). This will include: socio-demographic characteristics; presence of mental or physical illness; deceased-offender relationship; nature of any abuse between the deceased and offender; incident location and weapon used; the presence of alcohol or drugs; and criminal justice outcomes. Homicide rates per 100,000 population will be calculated for older adults (aged 65 years and older) and younger adults (aged 18-64 years), and compared as rate ratios using Poisson regression. Descriptive statistics and cross-tabulation will be generated for factors associated with homicide for older compared to younger adults. Homicide typologies based on deceased-offender relationship and motive will be explored within group and family homicides will be compared between older and younger adults.

Epidemiology of Homicide in Community-Dwelling Older Adults: A Systematic Review and Meta-Analysis

BACKGROUND

Empirical research investigating older adult homicide is sparse and rarely accumulated for greater insights. This systematic review and meta-analysis quantifies the prevalence and characteristics of homicide victimization among older adults (65 years and older) compared with younger adults (18-64 years).

METHOD

We searched Cumulative Index to Nursing and Allied Health Literature, Cochrane, Criminal Justice Abstracts, EMBASE, MEDLINE, ProQuest, PsycINFO, Scopus, and Web of Science for studies published before December 31, 2018 (International Prospective Register of Systematic Reviews registration: CRD42017054536). Included were English-language, original, peer-reviewed studies describing the homicide of older adults. Excluded were studies not meeting age criteria, residence as an institution, or with insufficient outcome variables. The review included 39 studies; 17 were included in the meta-analysis. Data were extracted via open access or from study authors. Heterogeneity was assessed through study-level random effects estimates.

RESULTS

Pooled homicide rates per 100,000 population were 2.02 (95% CI [1.23, 3.33]) for older adults (n = 35,325) and 3.98 (95% CI [2.42, 6.53]) for younger adults (n = 607,224; rate ratio = .51, 95% CI [0.37, 0.70], p < .001). Proportion estimates for older adults: victim female 46.3%, location home 71.4%, offender familiar 25.2%, compared to stranger, 24.2%, motive argument 36.1%, compared to felony 30.8%, and weapon firearm 24.5%. Older adults were significantly different to younger adult victims (p = <.001) for female (OR = 2.5, 95% CI [2.02, 3.10]), home (3.87, 95% CI [3.45, 4.35]), stranger (1.81, 95% CI [1.66, 1.98]), argument (0.33, 95% CI [0.28, 0.39]), felony (2.78, 95% CI [2.58, 2.99]), and firearm (0.38, 95% CI [0.36, 0.40]).

CONCLUSIONS

Homicide against older adults differs from younger adults and warrants specific research and tailored prevention strategies.

Medicolegal evaluation of geriatric deaths in Bursa, Turkey

Differentiation of natural and forced deaths observed in this age group is very important in the forensic medicine practice. In the present study, we aimed to medicolegal evaluation of demographic data and autopsy findings of judicial geriatric deaths in Bursa and around. Autopsy reports of the cases who have been taken to Morgue Specialization Office of Bursa Group Presidency of Forensic Medicine Institution and at 65 years and over, crime scene and deceased examination reports and data in the prosecution documents were assessed retrospectively between 2003-2008 in our study. During 6-year period, totally 5155 autopsies have been performed in Morg Specialization Office of Bursa Group Presidency of Forensic Medicine Institution. Among such cases, 870 (16.8%) were 65 years old and older. Cases who were 65 years old and older included 640 (73.6%) were male, 230 (26.4%) were female; and age average of males were found as 72.77±5.82 and as 75.33±7.03 in females. In terms of death origin, 434 (49.9%) were natural deaths, 267 (30.7%) were traffic accident, 102 (11.7%) were suicide and 52 (6%) were homicide. Origin of death of the remaining 15 (1.7%) could not be detected. In line with prolongation of life expectancy and increase in the geriatric population, it is observed according to our outcomes that an increase is detected in judicial geriatric death cases because of neuropsychiatric disease, leading a solitary life and psychomotor imbalance.

Retrospektive Mortalitätsstudie nichtnatürlicher Todesfälle der Generation 65+ im Obduktionsgut der Rechtsmedizin Frankfurt am Main anhand zweier Zeitintervalle

Hintergrund und Ziel der Arbeit

Aufgrund des demografischen Wandels ist mit einer Änderung des Altersspektrums bei den Obduktionen zu rechnen. Ziel der Arbeit war die Untersuchung der nichtnatürlichen Todesfälle, bei denen die Verstorbenen ein Mindestalter von 65 Jahren erreicht hatten, da dieser Populationsgruppe zukünftig eine wachsende Bedeutung zukommen wird.

Material und Methoden

In dieser retrospektiven Mortalitätsstudie wurden alle nichtnatürlichen Todesfälle mit einem Sterbealter ≥ 65 Jahren analysiert, die in den Jahren 2000–2002 (Zeitraum I) und 2013–2015 (Zeitraum II) im Institut für Rechtsmedizin des Universitätsklinikums der Goethe-Universität in Frankfurt am Main obduziert wurden. Für die Analyse der suizidal Verstorbenen wurden zudem Daten nichtobduzierter Selbsttötungen (n = 100) aus Besichtigungen aufgenommen.

Ergebnisse

Aus den 1206 Obduktionen resultierten 669 natürliche (55,5 %) und 404 nichtnatürliche (33,5 %) Todesfälle. Darunter ergaben sich 221 Unfälle (Zeitraum I n = 105; Zeitraum II n = 116), 82 Suizide (Zeitraum I n = 55; Zeitraum II n = 27), 41 Todesfälle im Zusammenhang mit medizinischen Interventionen (Zeitraum I n = 7; Zeitraum II n = 34) und 40 Tötungsdelikte (Zeitraum I n = 23; Zeitraum II n = 17). Verkehrsunfälle und Stürze bilden die größten Subgruppen bei den Unfällen. Erhängen und Erschießen sind die am meisten angewandten Suizidarten. Vergleicht man Zeitraum I mit II, so fällt die signifikante Zunahme von Todesfällen im Zusammenhang mit ärztlichen Maßnahmen auf. Eine signifikante Abnahme von Suizidenten ist durch die abnehmende Obduktionsrate in dieser Gruppe zu begründen. Die relative und absolute Fallzahl an Tötungsdelikten im Obduktionsgut weisen keine wesentliche Veränderung auf.

Diskussion/Schlussfolgerung

Die Ergebnisse dieser Studie stimmen großteils mit der Literatur überein. Im Zeitvergleich zeigt sich eine relative Zunahme nichtnatürlicher Todesfälle im gerontologischen Obduktionsgut. Dies wird durch den Anstieg von Obduktionen nach iatrogenen Komplikationen wesentlich mitgeprägt.

The incidence and epidemiology of eldercide in the city of Johannesburg, South Africa

The current study describes the incidence and epidemiological characteristics of eldercide (homicides among victims aged 60 years and older) in Johannesburg for the period 2001 to 2010. A retrospective population-based study was conducted on cases drawn from the National Injury Mortality Surveillance System. A total of 557 eldercides were recorded by NIMSS for the study period with an average annual rate of 23.1 per 100 000. The average annual rate for males was 42.4 per 100 000 and 8.9 per 100 000 for females. There was little variation in the rates by race. Eldercide victims were predominantly male (77.4%), black (48.3%) or white (43.2%), and were mainly killed by firearms (44.8%) or the use of blunt force (27.8%), in a private residence (66.0%), on a week day (53.8%) and during the day (56.1%). The study also found that the characteristics of eldercide varied across males and females, and across black and white race groups. The high incidence of eldercides points to the need for interventions that give special attention to the risk configurations and circumstances associated with these violent deaths.

Elder homicide by unique combination of different mechanisms of asphyxia

Elder homicide is a fatal outcome of elder abuse and neglect. Multifactorial homicidal asphyxia in an elderly man by combination of three different mechanisms is an uncommon incident. This following case demonstrates a very unusual murder of 74-year-old man in his own residence. Crime scene visit and postmortem examination revealed that the victim was killed by combined effect of ligature strangulation, traumatic asphyxia and smothering by plastic bag.

Elderly deaths in Ankara, Turkey

According to World Health Organization, the life expectancy at birth is increasing. An increase in life expectancy might result in increased morbidity and mortality in elderly. The increase in the elderly population also leads to an increase in medico-legal problems, as well. Autopsy is of high importance for determination of cause of death in clinical and forensic cases. The purpose of this study was to find out general characteristics elderly deaths by examining forensic autopsy records. Out of 7033 forensic autopsies performed between years of 2007 and 2011, 1324 were elderly deaths and were included in the scope of the study. The records of public prosecutor office, crime scene investigation and autopsy findings were examined. The majority of victims (70.6%) were male, while 29.4% were female, with a male to female ratio of 2.4/1. Victims' ages ranged between 65 and 96 years, and the mean age was 74.8 years. A great number of presented elderly deaths were due to unnatural causes, followed by natural deaths cases. Out of unnatural deaths, 63.2% were related to accidents, 23.7% were suicides, and remaining 13.1% were homicides. More than half (56.6%) of all suicidal deaths were due to hanging. Of natural deaths, the majority (82.7%) were due to cardiovascular system disease. In the presented series the cause of death was determined in 90.9% of all elderly deaths, which validates the need for a forensic autopsy. Data obtained through autopsy procedures is of high importance for death statistics.

Autopsy following death by homicide in 644 cases

The objectives of this study are to determine the cause of death and based on the wounds, to analyze the different epidemiological variables on homicide in Dakar. Included were all homicides cases where an autopsy was performed and these results recorded in the autopsy register. The data collected in our work included, identity, sex, age, place of crime (location), the cause of death (the causative agent and the anatomical region injured) and the mechanism of death (the pathophysiological phenomenon causing death). On average 56 cases of homicide a year are reported, ranging from 44 cases in 2005 to 80 cases in 1999. Extrapolated to the population of Dakar this corresponds to 1.9 homicides per 100,000 inhabitants. Victims aged over 55 years represented only 4.03% of all victims. 6.52% of cases were infanticide. The crimes mainly took place in the suburbs of Dakar (51.42% of cases). Hand held weapons were used in 578 cases (89.7%) followed by firearms in 44 cases (6.8%). The study of the age of the victims has some interesting points. The homicide of elderly people in Senegal was relatively low in contrast to what is found in a developed country. The youthfulness of our population also explains the large number of homicide victims between 21 and 25. Infanticide is a particular problem in Senegal. In our study, 50.6% of homicides were found in the suburbs of Dakar followed by the peripheral area which accounted for 29.3% of homicides. The incidence of homicide can be directly correlated with the level of economic development. This frequency is much higher where incomes are low and particularly affect young males. The study of this phenomenon should lead to better prevention. The victim-type in Dakar is a young man, aged 20-25 years, killed by an instrument with an injury to the skull, neck, heart or main arteries, causing bleeding and death.
