Mass-Spectrometry-Based Proteomics Reveals Organ-Specific Expression Patterns To Be Used as Forensic Evidence.

J Proteome Res 2016 Jan 8;15(1):182-92. Epub 2015 Dec 8.

Quantitative Biology Center, Eberhard Karls University of Tuebingen , Auf der Morgenstelle 10, 72076 Tuebingen, Germany.

Standard forensic procedures to examine bullets after an exchange of fire include a mechanical or ballistic reconstruction of the event. While this is routine to identify which projectile hit a subject by DNA analysis of biological material on the surface of the projectile, it is rather difficult to determine which projectile caused the lethal injury--often the crucial point with regard to legal proceedings. With respect to fundamental law it is the duty of the public authority to make every endeavor to solve every homicide case. Read More

The interaction between clothing and air weapon pellets.

Forensic Sci Int 2015 Jan 3;246:6-16. Epub 2014 Nov 3.

School of Science Engineering and Technology, Abertay University, Bell Street, Dundee DD1 1HG, Scotland, United Kingdom.

Comparatively few studies have been carried out on air weapon injuries yet there are significant number of injuries and fatalities caused by these low power weapons because of their availability and the public perception that because they need no licence they are assumed to be safe. In this study ballistic gel was tested by Bloom and rupture tests to check on consistency of production. Two series of tests were carried out firing into unclothed gel blocks and blocks loosely covered by different items of clothing to simulate attire (tee shirt, jeans, fleece, and jacket). Read More

Designing the ideal model for assessment of wound contamination after gunshot injuries: a comparative experimental study.

BMC Surg 2012 Apr 10;12. Epub 2012 Apr 10.

Department of Oral and Maxillofacial Surgery, Hannover Medical School, Hannover, Germany.

Background: Modern high-velocity projectiles produce temporary cavities and can thus cause extensive tissue destruction along the bullet path. It is still unclear whether gelatin blocks, which are used as a well-accepted tissue simulant, allow the effects of projectiles to be adequately investigated and how these effects are influenced by caliber size.

Method: Barium titanate particles were distributed throughout a test chamber for an assessment of wound contamination. Read More

Gunshot wounds to the lower extremity. A comprehensive review.

Clin Podiatr Med Surg 1999 Oct;16(4):597-615

Broadlawns Medical Center, Des Moines, Iowa, USA.

A thorough knowledge of the mechanisms by which penetrating projectiles disrupt tissue can assist the physician in evaluating and treating the wound in a rational manner. Projectile mass, velocity, shape, construction, and the characteristics and anatomic constraints of the tissue penetrated determine the amount, type, and location of tissue disruption. The possibility of additional injuries caused by secondary missiles and cavitation must be understood to distinguish between conservative versus surgical care of the patient. Read More

B Rybeck B Janzon

Acta Chir Scand 1976 ;142(3):201-7

Soft tissue wounds caused by spherical steel projectiles at various impact velocities have been studied. Energy absorption by the penetrated tissues and the size, form and location of the maximum of the temporary cavity are discussed on the basis of theoretical calculations. Morphological and angiographic findings support the assumption that steel spheres hitting at high velocity cause most damage near the beginning of the wound channel. Read More
