[Using of scanning electron microscopy for detection of gunshot residue].

Scanning electron microscope improves the possibility of investigation of surroundings near of gunshot wounds in forensic medicine, it is the next subsequent method for differentiating of area of entrance and exit wound, supplemental method for determination of firing distance, permit of detection (GSR) on the hand of shooter and ensured describing of samples and their stored. Detection of GSR provides many information about composition of bullet and primer. Authors are demonstrating the possibility of detection of GSR on experimental shooting to the krupon (pigs' skin) in different situation (such as in a room and in outside area) and using of different weapon (hand gun CZ No.75 and machine gun No.58).

[Mechano- and morphogenesis of gunshot fractures in the flat bones].

Gunshot fractures in flat bones, bullet defects in the continuum were studied in experiment. The laws of gunshot fracture formation were formulated. In far distance, bullet has a direct and radial blow action. The direct blow induces comminution and disintegration of the bone tissue with dislocation of bone fragments; radial blow potentiates bone destruction. Morphological characteristics of gunshot fractures of flat bones depend on the force of the direct and radial impact action and can be used for estimation of the far shot distance, kinetic energy and shape of the head of the shell.

[Detection and investigation of microparticles of biological tissues in gunshot wounds].

We studied feasibility of expert purposes solution in examination of gunshot bullet injuries by investigation traces of microparticles of tissues expulsed from the wounds and settled near the victim. Laws of such traces formation are established, feasibility of localization of the place of wounding, of the shot direction finding, definition of the gender, group, species of bioobject is shown.

[Assessment of accumulation of the shot products on the targets in shooting from a short-barreled gun with a muffler for estimation of shooting distance].

A practical expert task--to estimate shot distance and order of shots made in two victims from a gun with muffler--is described as illustration of opportunities of the complex investigation with experimental shots and emission spectral analysis of the targets. Distribution of the shot soot on the targets in shooting from the distance up to 1 m is analyzed.

[2 suicides with self-fabricated gunshot devices: technical forensic and morphologic ballistic characteristics].

Two suicides with home-made guns firing conventional ammunition are reported. Three different classes of homemade guns can be distinguished. Special characteristics of the interior and exterior ballistics of the home-made guns caused unusual muzzle imprints, intensive soot deposits at the entrance wounds and on the hands, intensive CO-effects, burns and in one case a skin laceration of the hand holding the weapon. The bullets showed a reduced penetration depth, characteristic firing marks were missing.

Forensic veterinary radiology: ballistic-radiological 3D computertomographic reconstruction of an illegal lynx shooting in Switzerland.

The lynx, which was reintroduced to Switzerland after being exterminated at the beginning of the 20th century, is protected by Swiss law. However, poaching occurs from time to time, which makes criminal investigations necessary. In the presented case, an illegally shot lynx was examined by conventional plane radiography and three-dimensional multislice computertomography (3D MSCT), of which the latter yielded superior results with respect to documentation and reconstruction of the inflicted gunshot wounds. We believe that 3D MSCT, already described in human forensic-pathological cases, is also a suitable and promising new technique for veterinary pathology.

Atypical gunshot entrance wound and extensive backspatter.

This case report describes a suicidal gunshot to the head using a solid hollow-point bullet (Quick Defense). There was an irregular skin defect measuring 16 x 6 cm on the right side of the head and a bone defect of 9 x 6 cm while a 1.2 x 0.7 cm skin defect was located at the left temple. This atypical wound morphology caused confusion at the scene but during autopsy, a muzzle imprint and an abrasion ring were found in the frontal aspect of the large skin defect in the right temporoparietal region, which therefore had to be the entrance wound. In addition, extensive backspatter consisting of brain tissue, bone fragments and blood had been expelled from the huge entrance wound and had travelled up to a distance of 4.6 m. The extraordinary entrance wound cannot be fully explained by special anatomical or ballistic features such as a muzzle velocity of 420 m/s or the solid hollow-point design of the bullet.

Gunshot injuries as a topic of medicolegal research in the German-speaking countries from the beginning of the 20th century up to the present time.

The 100th anniversary of the foundation of the German Society of Legal Medicine is a good opportunity to review its contributions to forensic wound ballistics. The present article gives an overview of the scientific development in this field with special emphasis on work pioneering new developments and findings valid up to the present day, for example the presence of carboxyhemoglobin in the vicinity of the entrance wound as a sign of a contact or close-range shot [A. Paltauf, Wien. Klin. Wochenschr. 3 (1890) 984-991, 1015-1017]; the correct interpretation of the muzzle imprint [A. Werkgartner, Beitr. Gerichtl. Med. 6 (1924) 148-161] and the retrograde ballooning of the bullet entrance region in contact shots [F. Hausbrandt, Dtsch. Z. ges. Gerichtl. Med. 38 (1944) 45-76; H. Elbel, Med. Welt 20 (1958) 343-345]; wound patterns from captive-bolt livestock stunners [H. Czursiedel, Dtsch. Z. ges. Gerichtl. Med. 28 (1937) 132-133]; singeing of synthetic fiber textiles in close-range shots with nitro powder ammunition [S. Berg, Arch. Kriminol. 124 (1959) 5-8,17-22]; the wound ballistic processes on penetration of the bullet and the origin of the abrasion collar [K. Sellier, Beitr. Gerichtl. Med. 25 (1969) 265-270]. More recently medicolegal research in the German-speaking countries covered the following subjects: studies of the dynamic bullet-target interactions in experimental gunshots to simulants and composite body models; use of modern imaging techniques (CT, MRI) in the pre-autopsy diagnosis of lethal gunshot injuries; injuries from blank guns; mechanisms of incapacitation by gunshot injuries; development of improved methods for the evidence of gunshot residues on the firing hand; backspatter from close-range shots; medicolegal contributions in the discrimination of accidental, homicidal and suicidal gunshot injuries.

Medical consequences of terrorist bombs containing spherical metal pellets: analysis of a suicide terrorism event.

OBJECTIVE: Various metal objects added to explosives increase and diversify the wounding from bombing; especially favoured are spherical missiles for their special injuring characteristics. Our objective was to study the medical consequences and ballistic effects on human tissue of spherical metal pellets used in terrorist bombings. METHODS: The clinical and forensic data of all bodily injured casualties of a suicide terrorist bombing in a crowded hotel dining room were analysed retrospectively. RESULTS: Of the 250 people at the scene, 164 were injured, with 91 (55.5%) suffering bodily injuries; 30 of them died. The immediately deceased had disseminated tissue damage and their bodies were saturated with steel spheres. Thirty-two immediate survivors sustained severe injuries (Injury Severity Score > or =16), and all suffered tissue penetration by the pellets. Twenty-three (32%) underwent surgery and 15 (21%) required intensive care. CONCLUSIONS: Metal pellets propelled by the explosion enhanced the secondary pattern of injury and injured even patients remote from the origin. Tissue destruction and specific organ injuries among survivors were limited. To evaluate and manage victims of terrorist bombings properly, medical teams should become familiar with these severe injuries.
