Diagnosis of a captive-bolt injury in a skull extremely destroyed by fire.

The authors report on a combined suicide of a 71-year-old farmer who fired a shot to his forehead with a livestock stunner before burning himself. As the fire was fueled by a pile of firewood it burnt for many hours, thus, causing subtotal incineration of the body. The remaining bones were calcined and reduced to a residual mass of only 3 kg. In spite of the extreme destruction, a circular bone defect corresponding to the site where the captive-bolt had entered the skull could be identified in the frontal squama. The example of this suicide is used to illustrate the problems of distinguishing between mechanical and thermal fractures. As expected, the attempted isolation and amplification of both nuclear and mitochondrial DNA for the purpose of identification was not successful.

[Fatal thoracic compression after being partially run over by an automobile].

The authors report on a fatal pedestrian accident in which the victim lay on the street and got under a car being run over by one of the front wheels. Both the car driver and the killed pedestrian were strongly alcohol-intoxicated at the time of the accident (2.45 a.m.). After the car had come to a standstill, the pedestrian remained trapped under the car until she was rescued by the fire brigade. On the basis of the autopsy findings and the technical expert opinion it could be reconstructed that the pedestrian's death was not caused by the consequences of being run over by the car, but by the subsequent compression of her thorax in the final accident position.

[Fatal accident with a special automobile].

The authors report on a traffic accident in which the passenger of a Light Four-wheeled Vehicle (Microcar) approved for use by a disabled person was killed after a rear collision with a compact car. The severity of the accident trauma was critically determined by the vehicle's light construction. Consideration is also given to the legal situation regarding registration and driver's license issues.

[Hemopericardium caused by endocarditis ulcerosa: an unusual cause of sudden death in adolescence].

The authors report on the case of a 18-year-old student who died suddenly and unexpectedly of a pericardial tamponade after perforated ulcer-polypous endocarditis of the aortic valve. The detection of aerococcus urinae--which usually causes urinary tract infection--on the inflamed aortic valve demonstrates an unusual pathogenetic chain linking complexes of findings in the urogenital system and the heart.

[Mixed fatal poisoning caused by taking L-methadone and chloral hydrate].

A 42-year-old female drug user who was enrolled in a methadone maintenance program was found dead in her apartment. Cause of death was an intoxication with chloral hydrate and L-methadone. Trichloroethanol (TCE), the primary metabolite of chloral hydrate, was quantified by solid phase microextraction (SPME) and GC/MS in heartblood (27 micrograms/ml) and urine (338 micrograms/ml). D- and L-methadone were differentiated by chiral HPLC, which showed that only L-methadone had been taken. The quantitation of L-methadone and its metabolite EDDP was carried out by GC/MS from heartblood (1300 ng/ml and 86 ng/ml, respectively), urine (5239 ng/ml and 4960 ng/ml, respectively) and gastric contents (159 ng/ml and 122 ng/ml, respectively). The concentrations of both--trichloroethanol and methadone--were in toxic ranges.

[Contact shot from infantry weapons with a flash-suppressor].

The number of reports on contact shots from firearms with a flash suppressor attached to the muzzle is small. On the basis of a case report (suicidal shot to the forehead with a Kalschnikow AKMS 47 assault rifle) the morphological peculiarities (characteristics soot pattern, relatively small powder cavity and only minor skin tears in the presence of a bony support) are presented and the conclusions to be drawn from the findings regarding the flash-suppressor, the shot distance, the angle of the shot and the way of holding the weapon are discussed.

[Homicide with postmortem opening of the thoracic and abdominal cavity--morphological, criminological and forensic-psychiatric aspects].

During a walk a man found the partially unclothed body of a 16-year-old girl in a field near a village in South Baden. The body showed numerous injuries caused by sharp force. Several stab wounds were discernible on the neck, the chest, the genital region, the back and the right thigh. Postmortem, the anterior wall of the trunk had been severed with one long cut reaching from the mons pubis to the jugular fossa. The injuries and the scene suggested homicide with a sexual motive. Already on the next day a male suspect was ascertained. Blood traces of the victim could be demonstrated on his car. The man confessed the homicide, but did not describe the course of events in detail. He denied a sexual motive for the homicide. The psychiatric examination did not furnish any clues to internal, neurological or psychiatric disorders. The perpetrator did not claim intoxication for the time of the offence, which might have been relevant for the question of criminal responsibility. Psychodiagnostically, it was found that he had a narcissistic personality structure with a pronounced lack of self-esteem, deficits in affect processing and control as well as anxiety and aggression problems. The man was sentenced to life imprisonment for murder.

[Suicide with multiple graze shots].

A 77-year-old man was found in his flat with a shot to the right temple. In spite of hospital treatment he died from the head injury the next day. The weapon at the scene used for committing the suicide was a pistol, make Kaba Special (calibre 6.35 mm). At autopsy, the right temporal region showed a surgically treated, originally stellate gunshot entrance wound with a powder cavity. Close to this penetrating gunshot wound there were 3 parallel graze shot injuries of the scalp. The autopsy findings were consistent with the assumption that all the shots had been fired by the victim himself with suicidal intent. The injury pattern is presented and discussed in relation to the results of the technical investigation of the weapon and the findings at the scene.

[Confusing injury findings in a suicidal gunshot fired to the chest from a carbine with a sawed-off barrel].

The stellate bullet entrance wound is one of the facultative features of a contact shot. For the formation of a star-shaped wound two factors are of special importance: first, an extensive bony support underlying the skin in the entrance region, and second, a strong propellant charge of the cartridge fired. Contact shots to the precordial region usually do not cause stellate entrance wounds, even if high-powered rifle ammunition is used. In the reported case, an injury pattern was observed that was not in line with normal findings and seemed confusing at first. Following a suicidal gunshot to the chest from a sawed-off carbine 98a (cal. 8 x 57 Js), a 4.5 cm wide, gaping bullet entrance wound with radiating tears was found. Instead of the usual pocket, the anterior thoracic wall showed a fist-sized area of destruction with extensive undermining of the subcutis. Not far from the entrance hole, a rib fragment had become displaced retrogradely thus perforating the skin from the inside out. The unusual pattern of findings could be explained by the fact that the barrel had been sawed off: as a result of this manipulation, a considerable part of the propellant charge had been converted outside the barrel, i.e. in the initial section of the bullet path.
