Damage on the body

Damage on the body and their peculiarities arising from mechanical impacts, can be characterized not only view (and sometimes instance) guns, but the mechanisms of its impact. Abrasions, bruises, wounds, fractures usually display a generic feature of traumatic subject.
Abrasions and bruises can testify kick a particular subject, such as belt buckle, leg, booted in laced shoes, and other Rough grasping fingers leaves on a typical places (shoulder, forearm, thigh, hip, neck) multiple bruises oval. The analysis of their number and localization sometimes allows you to set which hand the attacker they were caused to the left or right.
Quite characteristic are damaged (scratches, wounds) by blows with blunt objects with ribbed hitting the surface. Specific and bites with his teeth, which allow even to identify a specific person on dental status when comparing the corresponding fingerprints (see Fig. 36).
The study abrasions allows you to set the direction of the damaging of the object (Fig. 78) and identify individual particles (soil, sand, microscale glass). More objective information can be obtained in the study of the Russian Academy of Sciences. Detection of traces of sadnenia one of the wound edges, study all wounds, and differentiation of primary and secondary sections help to establish the conditions for the occurrence of damage.

When chopped injuries are diagnosed tracks on the bones and cartilages, some small foreign bodies and on.
Some types of piercing and piercing and cutting items are so specific damage, that it is fairly easy to diagnose species of objects (for example, damage to fork). The features which differentiate wounds and blunt and sharp objects (tools), are presented in table. 10.

The damage on the skin (especially in places where close subject bone) in the form of bruises in some cases reproduce the fabric of clothing, while the contours of his conform to the contours of the traumatic subject. The most objective view of the damaging properties of the object can be made on the basis of a comprehensive analysis of damaged clothing, skin, soft tissue and underlying bone.
