Homicidal asphyxia

Homicides due to asphyxia are relatively uncommon. To better understand the presentation of such cases, the files of the Bexar County Medical Examiner's Office were reviewed from January 1, 1985, through December 31, 1998, for all such homicides. A total of 133 cases were found. The largest category was ligature strangulation with 48 deaths (21 male, 27 female). Petechiae were present in the conjunctivae and/or sclerae in 86% of the cases; fractures of the hyoid and/or thyroid cartilage were present in 12.5%. There were a total of 41 deaths from manual strangulation (27 female, 14 male). Petechiae were present in 89% of the cases. In cases of manual strangulation, fractures of the hyoid, thyroid, or cricoid cartilage were found in all the male victims and slightly more than one half of the female victims. Twenty-six cases of suffocation were found; 20 of the victims were < or =2 years of age. Only 1 of these children had petechiae and/or scleral hemorrhage. Five deaths were due to choking. Three of the deaths involved adults who were gagged; 2 deaths involved infants with foreign material pushed into the mouth. Other categories of asphyxia were as follows: 9 deaths due to more than one form of asphyxia; 1 death due to hanging, and 3 deaths due to drowning. Rape was the motive in 66% of the female victims of ligature strangulation and 52% of those due to manual strangulation.     

Eyelid petechiae and conjunctival hemorrhage after cardiopulmonary resuscitation]

In the last few years, some reports claim that petechial bleedings found in the eyelids and conjunctivae of corpses may be resp. are caused by resuscitation efforts (= RES). Nevertheless, the numbers of cases were small and the selection of the cases presented to demonstrate this relation in our opinion was not convincing. In the material of our institute, the rate of autopsies in which the victims had been tried to resuscitate by professionals increased up to ca. 25%, including a substantial number of victims of homicides. If RES alone would cause petechial bleedings, serious problems would arise for the medical expert. We analyzed all cases of a period of 5 years, which were examined by 1 investigator. Among 474 autopsies, RES was done in 144 cases (31%). 19% of these victims presented petechial bleedings, predominantly in the conjunctivae, compared to only 11% in the non-RES group. However, this was not a consistent finding in all subgroups: If the group of acute cardiac deaths of middle-aged persons was taken separately, in the remaining material a statistically significant difference in the petechial rate between cases with and without RES was not present. The analysis revealed an influence of the following factors in the development of petechial bleedings: cause of death, age, constitution (body mass index). In the RES subgroup with the highest rate of petechial bleedings (acute cardiac deaths of persons between 40-60 years; n = 23; rate of petechiae = 50%) the frequency of petechiae could be explained by a combination of such factors. As a second way we investigated all persons in which RES was done in our Medical School during a period of 5 months. In no surviver petechiae were present; in the group of non-survivers (predominantly cardiac deaths), the petechial rate was 16%. According to the statements of the treating physicians, a development of petechial bleedings under RES was not striking in these cases or according to their general experiences. Although such a statement is of restricted value (because petechial bleedings are mostly not obvious without a special look for them), the complete absence of information of this aspect in the clinical literature is striking. If petechial bleedings would be a common consequence of RES, this finding should be well known in intensive care units. According to our experience, a clear causal relation between resuscitation efforts and petechial bleedings in the face is not likely.     

Cause and manner of death among users of anabolic androgenic steroids

Medicolegally investigated deaths among 34 male users of anabolic androgenic steroids (AAS) are described. Nine persons were victims of homicide, 11 had committed suicide, 12 deaths were judged as accidental and 2 as indeterminate. In two cases of accidental poisoning, the levels of pharmaceuticals and illicit drugs were considered too low to be the sole cause of death and AAS was considered part of the lethal polypharmacia. Chronic cardiac changes were observed in 12 cases. In two cases of accidental poisonous deaths, these changes were regarded as contributory cause of death. Homicides, suicides, and poisonings determined accidental or indeterminate in manner were related to impulsive, disinhibited behavior characterized by violent rages, mood swings, and/or uncontrolled drug intake. The observations in the present study indicate an increased risk of violent death from impulsive, aggressive behavior, or depressive symptoms associated with use of AAS. There are also data to support earlier reports of possible lethal cardiovascular complications from use of AAS. Furthermore, a contributing role of AAS in lethal polypharmacia is suggested. Finally, the observations indicate that use of AAS may be the gateway of approach to abuse of other psychotropic drugs.     

A study of various morphologic variables and troponin I in pericardial fluid as possible discriminators of sudden cardiac death

Pathologists frequently examine victims of sudden cardiac death. In some cases, a firm diagnosis of cardiac-related death can be made based on conclusive gross and histologic findings. In many other cases, we find evidence supportive of, but not diagnostic of, cardiac death (e.g., atherosclerotic coronary artery disease, cardiomegaly, myocardial scarring). A final cohort consists of cases of sudden death with minimal to mild cardiac disease, no other significant pathology, and negative toxicologic studies. This prospective study compared 38 cardiac-related deaths with 52 control cases with respect to concentrations of pericardial cardiac troponin I (cTnI), heart weight, evidence of old and/or recent myocardial injury, and presence of significant coronary artery disease. The influence of documented chest trauma and/or perimortem cardiopulmonary resuscitation (CPR) on levels of cTnI was also analyzed. Even though median cTnI levels were significantly higher in cardiac deaths than in controls (p = .003), cTnI was not found to be a significant predictor of cardiac deaths, as determined by discriminant analysis (p = .52). Heart weight >500 g, evidence of old and recent myocardial injury, and significant coronary artery disease were seen statistically more often in cardiac deaths than in controls (p < or = .005 in each case), and median age was significantly higher in cardiac deaths than in controls (p = .001). Based on a stepwise logistic regression model, significant coronary artery disease, old and recent myocardial injury, and heart weight >500 g were found to contribute significantly to the prediction of cardiac death. Finally, neither chest injury nor CPR significantly affected concentrations of cTnI in pericardial fluid. These data confirm that the presence of acute and remote myocardial injury, significant coronary artery disease, and cardiomegaly (heart weight >500 g) strongly supports the diagnosis of a cardiac-related death. In contrast to a recently published report, we do not find that elevated concentrations of cTnI in pericardial fluid are strong indicators of cardiac-related deaths using our methodology.     

Sudden death resulting from lesions of the cardiac conduction system

Sudden unexpected deaths in young persons with noncontributory histories, autopsy results, and drug screen results are a common problem in forensic pathology. As part of the evaluation of such cases, the cardiac conduction system (CCS) should be studied. To determine the type and incidence of lethal CCS lesions, the authors reviewed their files of sudden unexpected cardiac deaths with particular attention to cases with causes of death in the conduction system. Cases of sudden cardiac death in patients aged < or=40 years during a 10-year period (Michigan) and a 4 year-period (Spain) were selected from the files. From this group, cases were identified in which the cause of death was a lethal change in the CCS. The portions of the heart containing the CCS were excised, and at least one hematoxylin and eosin slide and at least one trichrome or elastic trichrome slide per block were studied. In the two centers, 381 cases of sudden cardiac death were identified. The most common causes of sudden cardiac death were arteriosclerotic narrowing of the coronary arteries, cardiomyopathy, and myocarditis. In 82 cases, there was no identifiable cause of death even after complete gross and microscopic autopsy was performed, a medical history was obtained, and a drug screen was performed. In 11 cases, the CCS contained lesions that were considered lethal: narrowing of the atrioventricular node artery by fibromuscular hyperplasia (7 cases) and atrioventricular node tumors (4 cases). The 11 cases accounted for 2.9% of the 381 cases of sudden cardiac death and 11.8% of the indeterminable cases. It was concluded that examination of the CCS in deaths in which the gross and microscopic autopsy, history, and drug screen fail to provide a cause of death can yield a cause of death in a significant percentage of cases. If heart block was not documented during life and no explanatory lesions were found during routine cardiac examination, examination of the CCS can yield valuable information.     

Delayed death in sudden infant death syndrome: a San Diego SIDS/SUDC Research Project 15-year population-based report

A fraction of SIDS cases have death delayed by successful CPR, yet they have not been compared to SIDS cases which were found dead or not successfully resuscitated. Our aims were to: (1) determine the percent of SIDS cases in the San Diego SIDS Research Project database for whom death was delayed by CPR and subsequent life support; (2) compare demographics, circumstances of death and autopsy findings of delayed death SIDS cases (delayed SIDS) with those whose deaths were not delayed (non-delayed SIDS); (3) examine the evolution of pathologic changes in delayed SIDS as a function of survival interval. A retrospective 15-year population-based study of 454 infant deaths attributed to SIDS revealed 29 delayed SIDS cases (Group I) and 425 non-delayed SIDS cases (Group II). Group I cases were significantly older than Group II cases (mean age 132 days vs. 102 days and p<0.0001). Eighty-nine percent of the Group I cases were discovered between 08.00 and 19.59 h; none were found between 00.00 and 07.59 h, compared to 38% of the Group II cases. Group I infants were found significantly more often away from home (at daycare, or at the home of a relative, friend, or baby sitter) than Group II infants (45% vs. 25%, p<0.05). There were no differences between groups with regard to gender, gestational age, type of delivery, bed sharing, URI within 48 h of death, ALTEs, a history of referral to child protective services, body position when placed or found, or face position when found. Pathologic changes were semiquantitatively evaluated; findings were characteristic of anoxic-ischemic injury that generally became more severe with increasing survival intervals. Anoxic-ischemic brain injury was the immediate cause of death in all delayed SIDS cases. Aspiration of gastric contents was identified in Group I cases surviving less than 48 h and was the likely etiology of acute bronchopneumonia occurring in 83% of the Group I cases. We did not identify factors that would reliably predict which SIDS cases might be discovered soon enough to allow earlier and more effective CPR and survival without permanent brain injury.     

What is the incidence and significance of "dry-lungs" in bodies found in water?

BACKGROUND: Drowning without aspiration of liquid, generally attributed to death from asphyxia while submerged and in laryngospasm, has been reported to occur in approximately 10% to 15% of drowning victims. OBJECTIVES: The occurrence of "dry-drowning" recently has been questioned and the hypothesis developed that "dry-lungs" in bodies found dead in the water could conceal more natural deaths than previously recognized. METHODS: Based on 578 selected adult victims who presumably drowned, we analyzed the correlation between the cases with a low combined lung/pleura liquid weight (< 1000 g and < 750 g) and a wide set of individual, circumstantial, and postmortem (PM) variables, using multivariate logistic regression analysis. Victims with lung weight < 1000 g were screened for long-QT syndrome (LQTS) founder mutations in KCNQ1 and KCNH2 genes. RESULTS: Of the 578 victims, 120 (20.7%) had a lung weight of < 1000 g, and 22 of these (3.8%) of < 750 g. Multivariate analysis showed a significant correlation for women (P < 0.001), for women aged 65 years or older (P < 0.001), and for men with prolonged PM submersion time (P < 0.001). "Normal" lungs were found in only 8 (1.4%) victims. Low-weight (< 1000 g), overdistended lungs with no sign of liquid penetration were seen in 11 (1.9%). No LQTS founder mutations were detected. CONCLUSIONS: The actual incidence of death of persons found in water who have normal lungs or do not have penetration of liquid into their airways, based on our study, is much lower (below 2%) than currently assumed.     

Analysis of cocaine-positive fatalities

A review of all autopsy and toxicology reports for persons dying in New York City in an 11-month period found 935 persons dying with cocaine in their bodies. Cocaine-positive fatalities were more likely in the young black and Hispanic and male population. In addition to cocaine and its metabolites, heroin and other opiates were found in 39% of persons and ethanol in 33% and barbiturates and minor tranquilizers in only 2% of the deceased. Cocaine overdose was responsible for 4% of the deaths and overdose with heroin and cocaine for 12% of the deaths. Violence was often the cause of death. Thirty-eight percent died of homicide, seven percent of suicide, and eight percent from accidents. Of particular interest were 6 persons who died of acute cardiac events directly related to cocaine as well as 4 cases of ruptured dissections of the ascending aorta, and 9 cases of cerebral hemorrhage. Autopsy findings for these individuals are described, and possible mechanisms of death are discussed.     

Petechiae in hanging: a retrospective study of contributing variables

Petechiae, one of the classic signs of asphyxia, are thought to be more frequently observed in cases of hanging where part of the body is supporting the victim's weight, ie, cases of incomplete hanging. However, there is very little evidence-based medicine to support this claim. The present study is intended to evaluate the relationship between petechiae and the type of hanging (complete vs. incomplete). Furthermore, several other variables were analyzed to determine if they contribute significantly to the presence of petechiae. An 8.5-year retrospective study of 206 cases of death by hanging reviewed autopsy reports for the presence of petechiae. For each case, the following information was also compiled: gender and age, height and weight, body mass index, the type of hanging (complete or incomplete suspension), the type of ligature used (narrow or wide), and whether or not the victim had received cardiopulmonary resuscitation maneuvers. Statistical analysis revealed that the incidence was higher among incomplete hanging victims compared with cases of complete suspension and that the incidence of petechiae varied inversely with the height of the victims. The other factors were not shown to contribute significantly to the presence of petechiae.     

Sudden epilepsy deaths and the forensic pathologist

Sudden unexpected deaths in epileptic persons are not rare events, most commonly encountered by the forensic pathologist rather than the clinician. Such deaths may represent 1-1.5% of all "natural" deaths certified by the medical examiner or coroner. The typical victim is a black male about 30 years of age who tends to abuse alcohol, with a history of generalized epilepsy for more than 1 year and likely for more than 10 years. There are a lack of obvious anatomic causes for the death at autopsy, but 60-70% of cases will have a lesion in the brain (most commonly old trauma) to explain the epilepsy. Most victims have no blood levels of anticonvulsant medications at the time of death. We have evolved a form for use by medical examiner/coroner's investigators at the scene to collect relevant information which will be of assistance to the pathologist in interpreting the case. Estimated prevalence of sudden epilepsy death, mechanisms, and other features of such cases are reviewed briefly.     

Endothelial cell membrane perforation of aorta and pulmonary artery in the electrocution victims

Some electrocution deaths occur without detectable current marks on the skin, making forensic examination to determine the true cause of death more difficult. Because arterial thrombosis was a frequent finding in victims of electrocution, we investigated injury to the endothelium of the aorta and pulmonary artery with a scanning electron microscope in five cases of death known to be caused by electrocution. We found large pores on the surface of endothelial cells of the aorta and pulmonary artery in those who died of electrocution, but no endothelial membrane perforation was found in those who died of cardiac diseases. These findings were present within 12h after death. Therefore, scanning electron microscopic evidence of endothelial perforation in the aorta and pulmonary artery could be a useful marker to identify electrocution for those victims without detectable current marks on the skin.     

Fatalities in the bathtub

A retrospective analysis concerning deaths in the bathtub was carried out in the Institute of Legal Medicine in Hamburg. The study includes 245 death cases between 1971 and 1988 (1% of all autopsies). 66 cases proved to be natural deaths, 76 were classified as suicides, 39 as accidents and 13 as homicides; 51 fatalities remained unclear with respect to one of these groups. Among the natural deaths sudden cardiac deaths were dominating (n = 39), among the suicides the intoxications (n = 37) and electrocutions (n = 20), and among the accidents the intoxications by carbon monoxide (n = 17) and electrocutions (n = 12). Out of 13 homicides only 2 were committed directly in the bathtub: One by drowning of a child and one by electric current via a hair dryer; in the other cases the dead body was put into the bathtub post mortem. About 50% of the victims were alcoholized. Signs of drowning were present in about 40% of all cases; the most frequent finding was emphysema aquosum.     

A rapid postmortem cardiac troponin T assay: laboratory evidence of sudden cardiac death

Postmortem examination may be useful in establishing the cause of sudden unexpected death. In many instances, however, limitations of staffing, budget, and time may force the pathologist to triage cases to external examination rather than autopsy. A rapid assay for cardiac troponin T (cTnT) to document suspected cardiac-related deaths may optimize the use of the time and resources of the autopsy pathologist. Peripheral blood was sampled percutaneously before each of 40 autopsies and placed in the well of the Cardiac T Rapid Assay unit in accordance with the included instructions, and the results were read after 15 minutes. The assay result, decedent age, postmortem interval, and evidence of cardiopulmonary resuscitation were tabulated and subsequently correlated with the cause of death. On final sign-out of each of the autopsies, the cause of death was determined to be cardiac-related (n = 20) versus the cause in non-cardiac control subjects (n = 20). This determination was made while the investigators were blinded to the cTnT assay result. Of the 20 cardiac deaths, 17 (85%) showed positive results for cTnT compared with 6 (30%) false-positive results among the 20 control cases; this result was statistically significant according to the chi-square test. In the over-50 age group, the sensitivity of this assay in detecting cardiac-related death was 91%, with a specificity of 86%. Perimortem cardiopulmonary resuscitation did not appear to result in false-positive results. In the appropriate setting, this rapid assay for cTnT can provide valuable data supportive of a cardiac-related death. This inexpensive test may best be used in triaging sudden deaths in persons over 50 to external examination versus complete autopsy.     

Acute lethal alcohol intoxication (author's transl)]

In 14,744 autopsy cases from an 18-year period 92 cases (of which 7 were ruled out because of decomposition were observed in which death was supposed to be due to direct acute alcoholic intoxication. In the police reports 81 persons were designated as chronic alcoholics or abusers of spirits. The blood alcohol level ranged between 2.04 and 4.92 o/oo. The cases studied were divided into two groups, one with low and the other with high lethal alcohol level. Fatty liver and cirrhosis were found with identical frequency in the two groups, whereas cardiac hypertrophy of obscure origin occurred markedly more often in the group with low lethal blood alcohol level. On the basis the possible mechanism of death in the cases with cardiac hypertrophy is discussed. Finally, the relation between the blood and urine alcohol concentrations observed in 72 cases is discussed. On the assumption that the water phase of the blood was 75 per cent of the total blood, death occurred in the persons without cardiac hypertrophy with fairly identical frequency either in the phase of absorption or the phase of elimination, whereas in the persons with cardiac hypertrophy death most often occurred in the phase of absorption. These statements should, however, be taken with some reservation, partly because the water phase of the blood may vary considerably post mortem (60-90 per cent) and partly because the urine alcohol concentration depends on serval variable factors.     

Mountaineering fatalities on Mount Rainier, Washington, 1977-1997: autopsy and investigative findings.

Mountain climbing is a popular recreational activity with a growing number of participants and associated fatalities. To define the characteristics of these fatal incidents and the typical autopsy findings in the victims, we reviewed the autopsy and investigative findings of all fatalities that occurred on Mount Rainier from 1977 through 1997. A total of 50 deaths occurred in 29 separate incidents. Fifty-eight percent of accident victims died as the result of a fall; another 34% died as a result of an avalanche. The incidents leading to death occurred at an average altitude of 3652 m (11,977 feet); range, 2073 to 4389 m (6800-14,400 feet). The average age of the victims was 31.2 years (range, 17-55 years), and 47 of the 50 were men (94%). Bodies were not recovered in 13 cases (26%). Autopsies were performed in 30 of the remaining 37 cases. At autopsy, the cause of death was ascribed to multiple injuries in 12 cases (40%), isolated head and neck injuries in 7 cases (23%), and chest injuries in 1 case (3%). Asphyxia and hypothermia were the cause of death in 8 cases (27%) and 2 cases (7%), respectively. The frequency of specific injuries is presented by anatomic region. The unique autopsy and investigative features of mountaineering deaths are discussed.     

Toxicological findings in victims of traumatic deaths.

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.     

Identification of the unidentified deceased: turnaround times, methods, and demographics in Fulton County, Georgia

CONTEXT: Multiple methods may be employed in an attempt to identify deceased individuals who are unidentified when reported to the medical examiner or coroner. The success and turnaround times of various methods differ. OBJECTIVE: To determine the number of deaths initially involving unidentified individuals, their demographics, the methods used and turnaround times for cases in which identification was successful and the portion of cases that remain unidentified for significant periods of time. DESIGN, SETTING, AND PARTICIPANTS: Retrospective case review of all decedents who were initially unidentified when death was reported to the Fulton County Medical Examiner in Atlanta, Georgia, during a 1-year period between May 2003 and May 2004. MAIN OUTCOME MEASURES: Rate per 1000 deaths which involved an unidentified decedent, tabulation of methods used to make identifications, and rate of cases remaining unidentified. RESULTS: Of 2279 deaths reported to the office, 100 were originally unidentified, resulting in a rate of 44 unidentified decedents per 1000 deaths reported. Those who remained unidentified involved 6 cases, resulting in a "cold case" rate of 2.6 per 1000 deaths. Seventy-eight percent were identified within 2 days, and the most common successful methods were visual identification (52%) and fingerprints (31%). Dental (10%), x-ray (4%), and other methods (6%) were least commonly used. Of the 94 persons identified, all identifications occurred within 29 days. DNA procedures were not needed in most cases, and in the few cases where such tests were needed, results were either unavailable or failed to show a match with known samples. CONCLUSIONS: The majority of unidentified deceased individuals were identified within 2 days, with visual verification or fingerprints accounting for about 83% of methods successfully employed. The medical examiner noted a rate of 44 unidentified deceased persons per 1000 death reports, with an ultimate "cold case" (long-term unidentified) rate of about 2.6 cases per 1000 death reports. These data may be useful in developing office policy and procedure regarding the procedural and temporal aspects of investigations centered on achieving identification and making dispositions of unidentified deceased bodies.     

Penetrating cardiac injuries. A pathological analysis of 20 autopsy cases

A total of 20 autopsy cases involving deaths due to penetrating cardiac injuries were analyzed pathologically: the causes of death of the victims who died before cardiorrhaphy were exsanguination or hemorrhagic shock in nine cases, pericardial tamponade in three, and a combination of the two in another three. Three of the remaining five cases of early postoperative death resulted from hemorrhagic shock, one resulted from pulmonary air embolism, and one resulted from a combination of hemorrhagic shock and coronary platelet embolism. We should pay more attention to air embolism and platelet embolism as causes of death of victims who have had penetrating cardiac injuries, whose exsanguinating hemorrhage and/or pericardial tamponade may be controlled by emergency-room thoracotomy and cardiorrhaphy.     

The Richard Cory phenomenon: suicide and wealth in Kansas City, Missouri

This case-control study investigates the relationship between suicide and wealth in Kansas City, Missouri. House and personal property appraisal data on all victims of suicide from 1998 and 2002 and victims from a control population of deaths reported to the Jackson County Medical Examiner during the same time interval were obtained from the Jackson County Government website. The controls were matched to suicide cases by race, gender, year of death, and age at death (+/- 1 year). Data from the 426 members of each group of suicides and controls indicate that suicide victims were: 1) 77% more likely than controls to have lived in houses rather than in apartments or trailers, 2) more likely than controls to have lived in more expensive houses (mean values dollar 70,143 versus dolllar 61,513 respectively, p = 0.04) and 3) more likely to have killed themselves because of factors other than financial strain (8.0% of suicides showed financial strain).     

Analysis of accidental deaths in mountain tourism and sport according to statistics from the Republic of Kabardino-Balkariia

Lethal cases in mountain tourism and sports in the Republic of Kabardino-Balkaria were studied for 1978-1995. A total of 152 accidental deaths were analysed. Most of the victims were males under 30 years of age. The greatest number of the accidents took place on Monday, in July and August. Many amateur visitors from abroad were among the victims. The main cause of death in the mountains of Kabardino-Balkaria for the 18 years studied was multitrauma of the body (69.7%). Hypothermia and obturation asphyxia with snow and compression asphyxia due to snowbreak account for 11.8 and 13.2% deaths, respectively; lightning killed 4%. Combination of high mountain hypoxia with exacerbated chronic somatic disease or hypothermia caused death in 1% victims. The authors propose how to improve forensic-medical expert examination of accidental death and safety in the mountains.
