Suicide by Gunshot Wound to the Posterior Head and Neck: A Retrospective Case Series and Review of the Literature

ABSTRACT

Suicide by firearm is a significant public health concern in specific regions of the world. Depending on firearm availability, any type of firearm may be used, including handguns, shotguns, and long rifles. Common entrance wound sites in suicidal gunshot wounds include the head, with classic gunshot wound locations including the temple, the forehead, the submental aspect of the chin, and inside the mouth. Occasionally, suicidal gunshot wounds occur in atypical body locations such as the back of the head and neck. Given their relative rarity, suicidal gunshot wounds in these regions may be mistaken for homicides. In this report, we present 5 cases of suicidal gunshot wounds to the back of the head and/or neck. In our series, we focus on differentiating each case from homicides involving gunshot wounds in similar areas of the head and neck.

Differentiating suicide from homicide in sharp-force fatalities with stab and/or incised wounds: A scoping review

The majority of sharp-force fatalities with stab and/or incised wounds are homicides. However, suicidal sharp-force fatalities with stab and/or incised wounds are also reported. Thus, distinguishing suicidal stab and/or incised wounds from homicidal stab and/or incised wounds is significant from the forensic perspective. This scoping review primarily summarizes the existing research findings on the differentiation of suicide from homicide in sharp-force fatalities with stab and/or incised wounds. The literature was systematically searched on February 28, 2023, using the PubMed database. A search string formed by a combination of keywords related to suicide, homicide, and stab and incised wounds yielded 23 records. After applying the eligibility criteria, six records/studies met the inclusion criteria and were included in the present scoping review. Results showed that the predictive strength of various parameters, either individually or collectively, in diagnosing the manner of sharp-force fatality as suicide or homicide is not always hundred percent accurate. Some of the important predictors of the homicidal manner of death in sharp-force fatalities include clothing damage, presence of defense injuries, presence of injuries caused by another type of violence other than sharp-force, vertically oriented chest stabs, and sharp-force injuries in the head and back anatomical sites. Some of the important predictors of the suicidal manner of death in sharp-force fatalities include the presence of tentative injuries, sharp-force injuries to the wrist, and the presence of a suicide note.

Sexual and gender identity and note-leaving among adult suicide decedents in the USA

BACKGROUND

Suicide is one of the leading causes of preventable death in the USA, representing a critical public health threat. Suicide risks differ for different populations. In particular, the sexual and gender minority (SGM) population remains at increased risk for suicide. One of the circumstances that may differ for SGM and non-SGM individuals is the propensity to leave a suicide note. Information regarding note-leaving may be helpful in informing suicide prevention and intervention.

AIMS

This study documents the differences in note-leaving in SGM individuals compared with non-SGM individuals, using recent data from the National Violent Death Reporting System (N = 98 515) and accounting for important covariates.

METHOD

We fit a logistic regression model with SGM status and covariates predicting note-leaving in suicide.

RESULTS

SGM decedents were 1.508 times more likely to leave a note than their non-SGM counterparts, controlling for demographic, mental health and substance use covariates.

CONCLUSIONS

These findings highlight the importance of tailoring suicide prevention and intervention efforts to meet the needs of SGM populations.

Socio-demographic and psychiatric profile of patients hospitalized due to self-poisoning with suicidal intention

OBJECTIVE

To identify the psychiatric profile of patients hospitalized due to self-intoxication associated with suicide-related behavior (SRB).

METHODS

In this retrospective single-center study, records of consecutive patients treated for suicidal poisoning in our Clinical Toxicology unit between 1st January 2012 and 31st December 2016, who received at least one psychiatric exploration during their inpatient stay, were analyzed with regard to epidemiological data, ingested substances, psychiatric and somatic comorbidities, suicidal circumstances and follow-up therapy.

RESULTS

Out of 1289 hospitalized patients, 1090 patients with complete data were analyzed. Mean age was 40.5 ± 17.2 years, 66.7% were female. 32.0% of patients had previously engaged in SRB, in 76.3% intention was suicidal. 64.7% of patients had a pre-existing psychiatric disorder (PD). Patients with a pre-existing PD more often displayed prior SRB than those without PD (40.7% vs 15.3%; p < 0.001; Fisher's exact test), used long-term/on demand medication (70.2% vs 38.9%; p < 0.001), distanced themselves from the current suicide attempt (65.9% vs 50.8%; p < 0.001) and had no detectable trigger (38.7% vs 18.1%; p < 0.001). Partnership conflict was the most commonly named trigger, and it was documented more often in patients without than in those with PD (41.6% vs 25.6%). After psychiatric reevaluation, most patients were diagnosed with mood disorders (29.7%) and stress disorders (17.0%); 32.8% of patients had a combination of two or more PDs.

CONCLUSION

Hospitalization due to self-poisoning is associated with pre-existing PD, prior SRB and access to psychiatric medication. Detection of these risk factors could allow timely introduction of effective preventive measures tailored to particularly vulnerable subgroups and appropriate relief. However, lack of a detectable trigger in many cases may hamper the identification of those at risk.

Last Words: Are There Differences in Psychosocial and Clinical Antecedents Among Suicide Decedents Who Leave E-Notes, Paper Notes, or No Note?

OBJECTIVE

Only a minority of suicide decedents leave a suicide note. Typically, the notes are handwritten on paper; however, electronic suicide notes have been reported with increasing frequency. This emerging phenomenon remains generally under-researched. The aim of this study was to compare the psychosocial and clinical antecedents of suicide decedents who left E-notes with those who left paper notes or no notes.

METHOD

The study was embedded in the Southwestern Ontario Suicide Study (SOSS). The SOSS was a three-year case series of consecutive deaths by suicide that occurred in the region between 2012 and 2014. Data on psychosocial and clinical antecedents were collected with a modified version of the Manchester questionnaire used in the UK.

RESULTS

Of the 476 suicides files reviewed, 45.8% contained a suicide note. A total of 383 separate suicide notes were left: 74.3% were paper notes and 25.7% were E-notes. The results of the multivariate regression analyses indicate that the likelihood of leaving a suicide note was negatively associated with a history of admissions to a mental health unit, while the likelihood of leaving an E-note was negatively associated with age, positively associated with presence of a mental disorder, and negatively associated with history of hospital admissions.

CONCLUSIONS

Future studies with larger samples need to consider the timing of the text messages, and appraise whether there was the intent of seeking help or rescue in the text messages.

Differences in Characteristics and Exposure to Stressors Between Persons With and Without Diagnosed Mental Illness Who Died by Suicide in Victoria, Australia

Background: Mental illness is an established risk factor for suicide. To develop effective prevention interventions and strategies, the demographic characteristics and stressors (other than, or in addition to, mental illness) that can influence a person's decision to die by suicide need to be identified. Aim: To examine cases of suicide by the presence or absence of a diagnosed mental illness (mental illness status) to identify differences in factors associated with suicide in the groups. Method: Logistic regression analyses were used to investigate mental illness status and exposure to stressors among 2,839 persons who died by suicide in Victoria, Australia (2009-2013), using the Victorian Suicide Register. Results: Females, metropolitan residents, persons treated for physical illness/injury, those exposed to stressors related to isolation, family, work, education, and substance use and those who had made a previous suicide attempt had increased odds of having a diagnosed mental illness. Employed persons had decreased odds of having a diagnosed mental illness. Limitations: The retrospectivity of data collection as well as the validity and reliability of some of the data may be questionable owing to the potential for recall bias. Conclusion: The point of intervention for suicide prevention cannot always be a mental health professional; some people who die by suicide either do not have a mental illness or have not sought help.

Demographic and Clinical Characteristics of Completed Suicides in Mexico City 2014-2015

Objective: To analyze sex differences in demographic and clinical characteristics of individuals who died by suicide in Mexico City. Method: Statistical analysis of residents of Mexico City whose cause of death was suicide, during two years period from January 2014 to December 2015, with a coroner's report. Suicide mortality rates were calculated by age, sex, and location within the city. The Chi-squared test was used to assess statistical differences. Results: From January 2014 to December 2015, 990 residents of Mexico City died by suicide (men: 78.28%, women: 21.72%). Among males, the highest mortality rates were among the groups of 20-24 and 75-79 years old, whereas in women, the group with the highest mortality rate was 15 to 19 years old. 74% of the sample used hanging as suicide method. However, men had higher rates of a positive result in the toxicology test (40%) (p < 0.05). There was no concordance between male and female suicide by city jurisdictions. Conclusion: Our results provide evidence that the characteristics of Mexico City's residents who committed suicide had significant sex-related differences, including where they used to live. Understanding the contributory factors associated with completed suicide is essential for the development of effective preventive strategies.

Suicide in Northern Ireland

Abstract. Background: The circumstances surrounding death by suicide can give us insight into the factors affecting suicide risk in particular regions. Aims: This study examined gender and circumstances surrounding death by suicide in Northern Ireland from 2005 to 2011. Method: The study analyzed 1,671 suicides (77% male and 23% female cases) using information contained from the coroner's files on suicides and undetermined deaths. Results: Hanging was the most common method and more than one third of the deceased had prior suicide attempts. There was evidence of alcohol use in 41% of the cases. Only, 61% of cases had recorded adverse events; most had multiple and complex combinations of experiences. Relationship and interpersonal difficulties were the most common category of adverse event (40.3%). However, illness and bereavement, employment /financial crisis, and health problems were also common. One third of those who died by suicide were employed, compared with 50.3% who were not in employment. Just over half (50.1%) were known to have a mental health disorder. Conclusion: The results provide the first profile of deaths by suicide in Northern Ireland. They highlight the need to target people who have difficult life experiences in suicide prevention work, notably men, people with employment, financial and relationship crises, and those with mental disorders.

Late-life suicide: Insight on motives and contributors derived from suicide notes

OBJECTIVES

The aims of this study were: (i) to investigate the proportion of older people writing suicide notes in New Zealand; (ii) to compare the socio-demographic and clinical variables of older suicide note writers and non-note writers; and (iii) to perform a thematic analysis of the content of suicide notes.

METHODS

The Coronial Services provided records of all suicide cases aged 65 years and over (n=225) between July 2007 and December 2012. We were able to determine whether there was a suicide note written in 212 cases. The content of 39 coroners/medical examiners' excerpts and 5 suicide notes was available for thematic analysis using a general inductive approach.

FINDINGS

88 (41.5%) older people left a suicide note. Logistic regression showed that female gender (OR=2.8, 95% CI=1.4-5.7, p=0.005) and Caucasian ethnicity (OR=13.7, 95% CI=1.7-111.0, p=0.014) are significantly associated with older people writing suicide notes. 33.3% of those who left a suicide note gave health-related reasons for their suicide and a significant proportion (73.3%) of them had underlying medical conditions. Another common theme is around people leaving specific instructions and wishes.

CONCLUSIONS

Apart from gender and ethnicity, suicide note writers are similar to non-writers on broad socio-demographic and clinical factors. Suicide notes indicated free will in and reasons for their suicide and emotional/farewell messages to their loved ones. Many documented poor quality of life or physical illness but the progression of these factors to suicide in older people should be further researched.

Who leaves suicide notes? A six-year population-based study

Popular culture insists on the significance of suicide notes, but research has yielded conflicting results about who leaves notes. Utilizing 6 years of suicides from a comprehensive statewide data surveillance system, differences were examined between cases with suicide notes and those without in terms of demographics, circumstances of the suicide, and precipitating circumstances. Of the 2,936 suicides, 18.25% included a note. Demographics and circumstances did not differ for cases with a note compared to cases with no note. Results have implications for working with people bereaved by suicide in helping understand that the notes are uncommon and not systematic. However, it is also possible that for some individuals, the content of a note is meaningful and can help or hinder their course of bereavement.

A 2-year psychological autopsy study of completed suicides in the athens greater area, Greece

OBJECTIVE

To study the characteristics of a sample of suicide victims from the Athens Greater Area using the psychological autopsy method for the first time in Greece.

METHODS

We studied all recorded cases of completed suicide for the 2-year time period November 2007-October 2009 collecting data from the victims' forensic records as well as from the completion of a psychological autopsy questionnaire.

RESULTS

335 persons were recorded as suicide victims. We contacted relatives of 256 victims interviewing those of 248 of them (96.9%). The differences regarding sex, marital and employment status between our sample and the general population were statistically significant (p<0.001). The male/female ratio was 3:1. Comparatively more victims were divorced, separated or single and a greater proportion were pensioners or unemployed. 26.0% of the victims had history of prior attempts (64.4% once, 20.3% twice and 15.3% more times). 42.6% were taking psychiatric medication-significantly more women than men according to blood tests; 14.2% had been hospitalized in a psychiatric clinic the year prior to their death. 84.8% have deceased at the place of suicide and 15.2% died in the hospital; 80.3% died indoors and 19.7% outdoors. Men died primarily by hanging or shooting by a firearm while women preferred jumping from height instead (p<0.001). As many as 48.8% had expressed their intention to die to their relatives; 26.6% left a suicide note.

CONCLUSION

Our study has shown that the psychological autopsy method is applicable and widely accepted yielding results comparable to the international literature. Specific parameters associated with suicide have been studied for the first time in Greece.
