Evolution of the Psychological Autopsy: Fifty Years of Experience at the Los Angeles County Chief Medical Examiner‐Coroner's Office

The origin of the psychological autopsy was in the late 1950s and the result of a collaboration between the Los Angeles County Chief Medical Examiner‐Coroner's Office and the Los Angeles Suicide Prevention Center. It was conceptualized as a thorough retrospective analysis of the decedent's state of mind and intention at the time of death. It was used initially in “equivocal” deaths where the manner of death was possibly either suicide or accident. Later, it was used in cases where a party (primarily family members) protested the Medical Examiner‐Coroner's suicide determination. Over the past 25 years, the University of Southern California Institute of Psychiatry, Law, and Behavioral Science has served as the psychiatric/psychological consultants to the Coroner's Department. Research findings, the use of this approach in high‐profile cases, and the most recent manner in which the psychological autopsy is conducted are discussed.     

Fatal Intoxications in a Forensic Autopsy Material from Epirus,Greece, During the Period 1998‐2010

In this retrospective study, we report the epidemiological characteristics of all poisoning deaths in Epirus, Greece, from 1998 to 2010; we present the toxicological findings and the statistical evaluation of the results. This is the first detailed scientific report on all the officially certified poisoning deaths concerning part of the Greek population. A total of 126 poisoning fatalities were recorded, 67 of them being mono‐intoxications (53.2%). The cause of poisoning was as follows: drugs of abuse (60%); carbon monoxide (19.8%); pesticides (9.5%); corrosives (4.8%); pharmaceuticals (4.8%); and spider bite (0.8%). The most frequently detected poisonous substances were as follows: heroin (65 cases), ethanol (55), benzodiazepines (42), carbon monoxide (25), cocaine (17), cannabinoids (17) and pesticides (12). Increasing tendency in poisoning death rates was recorded, due to an increase in accidental poisoning deaths attributed mainly to drugs of abuse (total, accidental, and drugs‐of‐abuse poisoning death rates per 100,000 inhabitants per year were 1.87, 1.19, and 0.79, respectively, in the period 1998–2002 and 3.97, 3.41, and 2.55, respectively, in the period 2007–2010).     

An Autopsy Case in Which Self‐Bloodletting Via a Cervical Blood Access Led to a Fatal Outcome*

Abstract: A 48‐year‐old woman was found dead on a chair in her living room. She had received dialysis every day because of chronic renal failure for the past 15 years. On a table beside her, there was a mirror and 10‐mL syringe on a napkin. A stopper was out of place in a portion of a three‐way blood access tube established in the right cervical region, and blood coagulation was noted in the lumen. There was a bloodstained measuring cup on the floor. Autopsy findings included a large number of shunt traces in the bilateral infraclavicular fossae and upper limbs, as well as the cervical blood access terminal reaching the right atrium via the internal jugular vein to superior vena cava. Various organs showed anemia. Neither a fatal lesion nor injury was noted in the main organs. Therefore, this patient may have committed suicide by self‐bloodletting via a cervical blood access.     

Suicidal Decapitation by Hanging—A Population‐based Study

A prospective study was undertaken at Forensic Science SA over a 15‐year period from July 2002 to June 2017 for all cases of adult (>18 years) suicidal hangings with decapitation. A total of 1446 cases of suicidal hangings were identified from a general population of approximately 1.5 million (1206 males—age range 18–97 years, average 42.6; and 240 females—age range 18–96 years, average 40.1). Only three cases of decapitation were found, all from long‐drop hangings; these consisted of three males (ages 32–55 years; average 45 years). Spinal transections had occurred between the first and second, second and third, and third and fourth cervical vertebrae, respectively. In this study, the number of suicidal hangings with decapitation represented only 0.2% of the total number of hangings. These events are therefore extremely rare, most likely due to most suicidal hangings occurring from relatively low levels in a domestic environment.     

Planned Complex Occupation‐related Suicide by Captive‐bolt Gunshot and Hanging*

Abstract: Planned complex suicides are committed by using two or more previously planned methods simultaneously to make sure that death will occur even if one method fails. Herein, we presented a case of occupation‐related planned complex suicide, committed by captive‐bolt gunshot and hanging. A 29‐year‐old man, who worked as a butcher, was found dead in the stable, hanging by the neck with a captive‐bolt gun embedded in the forehead region of his head. The hanging was complete. Along the bolt canal were bone fragments, and at the end of the path was the punched‐out fragment of the skin and soft tissue. There were no fractures of the hyoid bone and laryngeal cartilages, and a superficial hemorrhage was present in the right sternocleidomastoid muscle. Our case underlines the utility of forensic autopsy and death scene investigation in reconstructing the mechanism of death, as well as the dynamics of the event.     

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.     

Suicidal electrocution in Sydney: a 10-year case review

A retrospective study was undertaken of all cases of death due to suicidal electrocution in Sydney, Australia between 1996 and 2005. A total of 25 cases were identified with 20 cases (80%) as a result of direct attachment to an electrical outlet and five cases (20%) as a result of immersion in a body of water with an electrical appliance. Twenty of the 25 individuals were men (mean age = 57 years, range 22-90) and five were women (mean age 67, range 53-88). At least 35% of decedents were either currently working or had worked as electricians. Electrical timers had been used in eight (32%) cases, the fuse blown in one case, but the remaining 16 (64%) bodies were "live" on arrival of witnesses or electricity personnel. This study demonstrates the phenomenon of electrical suicide as a regular occurrence in Sydney. We highlight the need for investigators and emergency workers to remain vigilant upon discovery of electrical suicides, due to the fact that most bodies remain electrically active after death.     

Suicidal Shotgun Wound Employing a Shotgun Barrel,a Shotgun Shell,and a BB*

Abstract: A vast majority of firearms‐related suicides involve the conventional use of a properly functioning, intact firearm. Occasionally, forensic investigators encounter a case wherein the firearm suicide victim employs some form of unconventional use of a weapon, or utilizes an unusual weapon type. In this case report, the authors present an unusual case in which a man committed suicide by using a shotgun shell, a shotgun barrel (separate from the rest of the gun), and a BB. Some confusion as to the cause and manner of death was present during the initial scene investigation. Examination at autopsy revealed the cause of death to be a shotgun wound of the chest and prompted further scene investigation. Therefore, this case serves as another example of the importance of cooperation between scene investigators and forensic pathologists when investigating a death. A review of suicidal firearm cases using unconventional means and/or firearms is presented.     

Suicidal Drug Overdoses in New Mexico: A 5‐year Retrospective Review

To better understand the changing toxicology trends in suicidal drug overdoses in the setting of an increased national trend of multidrug overdoses, a retrospective review of electronic records from New Mexico's Office of the Medical Investigator database was performed between 2008 and 2012 to assess the drug type and current risk factors in suicide deaths. Information on demographics, circumstances, suicide risk factors, toxicology findings, and death certificates was collected and analyzed. Three hundred and forty‐two suicide cases of suicide overdoses were identified. Decedents were predominantly female (61.8%). Scene investigation revealed risk factors including suicide ideation (47.4%), previous suicide attempts (38%), and suicide note (38%). Psychiatric illness was present in 72% of cases, with depression being the most common illness. Chronic pain was seen in 27.2% of cases. Most deaths were attributed to multiple drugs (76%). Utilizing the toxicology information will assist in creating public awareness and provide a framework to support targeted efforts to attempt to prevent future suicides.     

A Ten‐year Study of Suicides from a Rural/Suburban County

This study will discuss trends in suicide data compiled over 10 years in Dutchess County, NY, from 2004 to 2013. These data were based on reporting and examination standards recommended by the National Association of Medical Examiners and Department of Justice death investigation standards. Almost 300 cases were analyzed in terms of the deceased's gender, age, race, method of suicide, and weapon used. Results from this study agree with other reports showing significant differences for method of death both in terms of age and gender, with men more likely to choose firearms and women more likely to choose overdose. Furthermore, older persons were more likely to commit suicide by firearms, and the younger persons were more likely to commit suicide by overdose. However, other areas, such as method of suicide, differ from national statistics.     

Homicide–Suicide in Cuyahoga County,Ohio, 1991–2016

Research on homicides followed by suicides has relied heavily on small samples and relatively short time spans of data. This study helps to fill this gap by examining 26 years of homicide–suicide data from Cuyahoga County, Ohio, between 1991 and 2016. The main data source for the study is medical examiner files. Analyses of the data indicate the rate of homicide–suicide in Cuyahoga County is consistent with other studies but fluctuates considerably across years studied. The majority of victims are female while perpetrators are overwhelmingly male. Black people are overrepresented as victims and offenders. Use of drugs and/or alcohol leading up to the incident is common among perpetrators. Both the homicides and suicides were overwhelming committed with firearms. When comparing our results to the typology of murder–suicides developed by Marzuk, Tardiff, and Hirsch (JAMA 1992;267:3179), we find amorous jealousy is a significant motivating factor in a many cases, including those involving nonintimate partners. Our findings underscore the importance of widespread use of lethality assessment instruments.     

Manners of Death in Drug‐Related Fatalities in Florida

To understand the mortality patterns among drug users and potential risk factors, we evaluated drug‐related deaths reported to the Florida Medical Examiners Commission from 2001 to 2013, by substances, demographics, and manner of death. The annual drug‐related fatalities increased by 57% from 2001 to 2013 (total n = 100,882); 51.8% were accidental, 7.9% homicide, 18.6% natural, and 19.6% suicide. The different manners of death exhibited distinct demographic profiles and drug composition. The gender gap was more prominent in homicide. Age ≥55 years was more closely associated with natural death and suicide. Age <35 years and central nervous system (CNS) stimulants including amphetamines and cocaine showed higher relative risks for accidental death and homicide, whereas CNS depressants including benzodiazepines, carisoprodol, opioids, and zolpidem were more strongly associated with accidental death and/or suicide. The findings aid in identifying populations more vulnerable to drug‐related deaths, developing targeted interventions and thereby improving efficiency of preventive efforts.     

Pacemaker/defibrillator evaluation at Los Angeles County Department of Coroner*

Pacemakers and implantable cardioverter-defibrillators (ICDs) are implanted medical devices for the treatment of cardiac arrhythmias. These devices are now commonly encountered in the postmortem situation. The Los Angeles County Department of the Coroner uses the services of a cardiac electrophysiology consultant to interrogate pacemakers and ICDs, producing a detailed picture of the cardiac events recorded by the device. We have used this method to evaluate 20 cases where the ICD or pacemaker provided significant information. We report four forensic cases to illustrate the different applications of pacemaker interrogation and its contribution in forensic investigation. This technique was used to establish identification of the decedent, to determine the cause and time of death, and to determine whether device malfunction could have played a role in the death. We conclude that detailed evaluation of the pacemaker or ICD in selected cases may provide essential information to the forensic pathologist.     

Implications of Genital Mutilation at Autopsy

Given the potential significance of mutilation of the external genitalia in medicolegal fatalities, a review of the literature was undertaken to identify subcategories. Such mutilations may have been sustained sometime before death, around the time of death, or after death. The most common type of ante mortem genital mutilations involves cultural practices such as male circumcision. Less common male mutilations such as subincisions are tribally based. Female genital mutilation is found particularly in African, Middle Eastern, or Asian populations. Self‐inflicted genital injuries are most common in males and may be related to attempts at suicide, or to self‐harming practices. The latter have a strong association with psychiatric illnesses. Postmortem injuries may arise from animal predation or deliberate mutilation of a corpse. The latter may be associated with ante mortem genital injuries in sadistic homicides. The range of possible causes of genital mutilations in forensic cases necessitates extremely careful evaluation.     

Childhood Fatalities in New Mexico: Medical Examiner‐Investigated Cases, 2000–2010

To better understand risk factors and populations at risk of childhood fatalities, a review of all records of childhood deaths (≤19 years) between 2000 and 2010 from New Mexico's statewide medical examiner was conducted. Annually, 313–383 childhood deaths were investigated (3820 total). Males and American Indians were overrepresented (62% and 20.4% of deaths, respectively). The most common manner of death was natural (44.8%), followed by accidental (31.4%), homicide (8.8%), suicide (8.8%), and undetermined (4.1%). Infants under 1 year of age accounted for 41.4% of deaths. Motor vehicle crashes were responsible for the majority of accidental deaths (69%), followed by unintentional overdoses (6.9%), and drowning (5.3%). Gunshot wounds, either intentional or unintentional, caused 10.7% of childhood deaths. Complete medico‐legal investigation of childhood fatalities is needed to provide public health agencies with adequate data to evaluate and prevent childhood deaths.     

Concentrations of Opiates and Psychotropic Agents in Polydrug Overdoses: A Surprising Correlation Between Morphine and Antidepressants

Abstract: The relationship between postmortem concentrations of morphine and co‐detected psychoactive drugs in fatal overdoses is examined. Morphine and other drugs were detected in 161 medicolegal autopsy cases. Subsets of these morphine‐positive cases based on drug class were established, including opioids, antidepressants, ethanol, benzodiazepines, and “other.” Each subset was split into high or low concentration groups based on median drug concentrations. Morphine concentrations of the [high] and [low] groups were compared, with no significant difference in morphine concentration identified in the opioid, ethanol, or benzodiazepine subsets. The “other” drug class was too heterogeneous for statistical assessment. Morphine concentrations did show a significant direct relationship (p = 0.01) with antidepressants, namely increased concentrations of antidepressant drugs are associated with an increased concentration of morphine. This trend probably remains even after excluding cocaine‐positive cases. The unsuspected finding that postmortem concentrations of antidepressants positively correlate with morphine levels may be important in the treatment of depression in drug addicts.     

Usefulness of Systematic Histological Examination in Routine Forensic Autopsy*

Abstract: The forensic community does not agree on the need to perform histological examination at forensic autopsy. The aim of our study was to determine the usefulness of systematic standard histology in forensic autopsies. A prospective study was carried out on 428 autopsy cases for which standard histological examination was systematic. Mechanism of death not shown by gross anatomic findings was discovered by histology in about 40% of the cases. Cause of death was established by only histology in 8.4% of the cases. Microscopic findings affected the manner of death in 13% of the cases. Histology provided complementary information about prior medical condition of the deceased in about 49% of the cases. Traumatic lesions were better documented by histology in about 22% of the cases. According to the results of our study, systematic standard histology for the main organs should be used in routine forensic autopsies.     

Six‐Year Retrospective Study of Suicidal Hangings: Determination of the Pattern of Limb Lesions Induced by Body Responses to Asphyxia by Hanging*

Abstract: The objective of the present study was to estimate the proportion of hanging victims presenting with limb lesions, to compare this rate between hanging in restraint spaces and in more open settings, and to describe the usual pattern of limb lesions associated with hanging. Two hundred and seven cases of suicidal hanging were retrospectively reviewed and compared to 45 homicidal nonhanging strangulation victims. Bruises incidence was significantly lower in hanging victims (19.8%) compared to homicidal strangulation victims (55.6%). Bruises were more commonly encountered in restraint areas such as closets and staircases (56.3% and 66.7%, respectively) than in more open settings such as barn, bridge, fence, and park. Limb bruises on hanging victims were generally located on the posterior upper limb or the anterior lower limbs, whereas strangulation victims did not display this preferential bruises concentration. Possible suspicion criteria for limb bruises distribution are discussed, in relation to physiopathology of human asphyxia by hanging.     

A Policy for the Retention and Extended Examination of Organs at Autopsy*

Abstract: Recent organ retention scandals and law suits have created a focus on the practice of saving postmortem tissues for extended examination or research purposes. The New Mexico Office of the Medical Investigator (OMI) established a policy to notify families about organ retention and the subsequent disposition of the tissue. The OMI examined the success of this policy in regards to the retention of brains for extended examination by analyzing data abstracted from verbal consent forms from 2003 to 2006. During this time, 715 cases were identified as needing an extended examination of the brain. The percentages of brains saved in any given year, as a percent of the total number of autopsies performed that year, were: 2003 6.5%, 2004 10.4%, and 2005 11.8%. The disposition was cremation in 79% of cases, release with the body after a determined period of time in 14%, and cut fresh in 4%. In conclusion, the instigation of a policy on the verbal notification of the next of kin when organs are retained can be successfully implemented.     

Suicidal hanging resulting in complete decapitation--forensic, radiological, and anthropological studies: a case report

The authors report a case of complete posthanging decapitation. The decapitated corpse lay against a pillar of a road bridge. The head had rolled 5 m from the trunk. The bridge was 7.2 m above the road level. The rope was 3.6 m long, its lower end was 3.6 m from the ground and its diameter was 10 mm. The noose used was a slip knot. Plain X-rays of the skull and cervical spine were obtained. The skull X-rays showed air in the meningeal spaces, in both lateral and third ventricles. The severance plane of the cervical spine was between the third and the fourth cervical vertebrae. No other cervical vertebral injuries were noted. At autopsy, the brain was macroscopically unremarkable except for air in the meningeal veins. The decapitation injuries of the head and the torso corresponded perfectly, without apparent loss of substance. The severance plane was confirmed. Dry bone study was carried out. Except for fractures of the extremities of the spinous processes of the second and third cervical vertebrae, no other bone injury of the spine was seen. The cervical vertebrae displayed numerous osteoarthritic lesions. The traditional hangman's fracture was not found. To the best of our knowledge, this is the first report of complete posthanging decapitation with a severance plane between the third and fourth cervical vertebrae.
