Protection or peril? An analysis of firearm-related deaths in the home

To study the epidemiology of deaths involving firearms kept in the home, we reviewed all the gunshot deaths that occurred in King County, Washington (population 1,270,000), from 1978 through 1983. The medical examiners case files were supplemented by police records or interviews with investigating officers or both, to obtain specific information about the circumstances, the scene of the incident, the type of firearm involved, and the relationship of the suspect to the victim. A total of 743 firearm-related deaths occurred during this six-year period, 398 of which (54 percent) occurred in the residence where the firearm was kept. Only 2 of these 398 deaths (0.5 percent) involved an intruder shot during attempted entry. Seven persons (1.8 percent) were killed in self-defense. For every case of self-protection homicide involving a firearm kept in the home, there were 1.3 accidental deaths, 4.6 criminal homicides, and 37 suicides involving firearms. Hand-guns were used in 70.5 percent of these deaths. The advisability of keeping firearms in the home for protection must be questioned.

Positional asphyxia during law enforcement transport.

Three cases of positional asphyxia are described that occurred while victims were in a prone position in rear compartments of police patrol cars. These deaths are attributed to positional asphyxia. Autopsy findings and specific scene and circumstantial correlations of the investigation are discussed with emphasis placed on the limitations of interpretation of the anatomic changes at autopsy.

Effects of positional restraint on oxygen saturation and heart rate following exercise.

This report assesses the effects on peripheral oxygen saturation and heart rate that positional restraint induces when a person is prone, handcuffed, and “hog-tied.” Peripheral oxygen saturation and heart rate were monitored at rest, during exercise, and during recovery from exercise for 10 adult subjects. The effects of positional restraint produced a mean recovery time that was significantly prolonged. Consequently, the physiological effects produced by positional restraint should be recognized in deaths where such measures are used

Correlation of Circumstances with Pathological Findings in Asphyxial Deaths by Hanging: A Prospective Study of 61 Cases from Seattle, WA

Correlation of the circumstances of death with the pathologic findings in this prospective study of deaths by hanging affords insight pertaining to certain of the pathophysiologic mechanisms involved in fatalities of this type. The presence of conjunctival and facial/periorbital petechial hemorrhages correlates with increasing levels of body support below the point of ligature suspension. Hyoid bone and/or thyroid cartilage fractures (found in 26% of cases) are most frequently identified in those persons found completely suspended and in victims in the older age ranges. No hyoid bone/thyroid cartilage fractures, internal soft tissue injury, or petechiae were present in 13 (21%) of the study cases.

Death from law enforcement neck holds.

ABSTRACTWe report two deaths which resulted from the use of neck holds by law enforcement officers. The mechanisms of death are discussed in addition to an assessment of the use of neck holds by law enforcement personnel. The hazards of neck holds are emphasized and we review those conditions where

Artifactual injuries of the larynx produced by resuscitative intubation.

Over a period of 9 months we examined a series of 50 deaths due to natural and unnatural causes in which there had been endotracheal intubation and chest compression during resuscitation at the scene or in the emergency department shortly before death. In 37 of 50 cases (74%) there were airway injuries directly resulting from the intubation procedure which we documented using a standardized protocol and photography. Specific airway injuries, ranging from petechiae to contusions, included oral injury (28%), posterior pharyngeal injury (16%), epiglottic injury (22%), piriform recess injury (12%), laryngeal and tracheal mucosa injury (64%), strap muscle hemorrhage (14%), and cutaneous injury of the neck (4%). In addition, we recorded the presence of facial (6%) and conjunctival petechiae (21%) and attributed these changes to resuscitative chest compression. No cases had associated fractures of the hyoid or thyroid cartilage. Based on our findings, we conclude that resuscitative intubation can cause artifactual injury that may mimic inflicted injuries caused by neck compression, including strangulation and neck holds.

Use of facial approximation techniques in identification of Green River serial murder victims

Since 1982, the remains of 41 victims of the Green River Serial Murderer have been recovered. The majority were discovered as skeletal remains, and 24 facial approximations have been used in attempts to develop leads for identification of nine of these victims. Nine different artists were used. Interpretations of the same victim varied greatly. For those victims subsequently identified, resemblance of the facial approximation to the deceased showed considerable variation, but in some cases was quite accurate. This experience created a unique opportunity to compare different methods of facial approximation techniques and artists, and to comment on their efficacy in aiding identification.

The Perils of Investigating and Certifying Deaths in Police Custody

Procedures leading to the proper investigation and certification of deaths occurring in police custody are discussed. The importance of training and experience, of interchange of information between investigator and forensic pathologist, and of common sense in the pursuit of fairness toward this end is emphasized.

Recovery of decomposed and skeletal human remains in the "Green River Murder" Investigation. Implications for medical examiner/coroner and police.

The Green River Murder Investigation in King County, Washington, is currently the longest active serial murder investigation in U.S. history. During its course, over 26 separate scenes with from one to five victims each have been processed. The experience of the authors is presented in order to acquaint other agencies with techniques of outdoor scene processing that have evolved during recovery of remains from Green River and other skeletal cases.

Atlanto-occipital disarticulation. Accident characteristics

A retrospective study of cases of atlanto-occipital disarticulation was conducted to describe incident characteristics: 24 cases were identified, including nine motor vehicle drivers, two passengers, seven pedestrians, and five motorcyclists; one other person had fallen four stories. The highest rates were found among motorcyclists and pedestrians. Atlanto-occipital disarticulations occur in high-energy impacts and collisions and are associated with aortic laceration in 25% and basilar skull fracture in 21% of such cases. Current restraint systems and motorcycle helmets do not appear to prevent this generally rapidly fatal injury.
