Injuries for firearm the injuries produced for detonation of firearm if must, more frequently, the bullets of that á lead load (granules). Therefore it is necessary, is necessary to give attention to this type of wound. When the projectile reaches the organism - and in it it penetrates can cross it or be in restrained it. If to consider the tunnel that the projectile creates in the body of the victim, we will see that it can be penetrating or transfixante. We must then, to study: entrance orifice - exit orifice - restrained projectiles I - Orifice of entrance: it has some characteristics, to know: Form: The projectile depends on the way for which reaches the target. If the penetration axle will be perpendicular á surface, the orifice will tend to copy the form of the transversal cut of the bullet: to circulate. However the retraction of fabrics provokes has taken deformation, 0 variable with the direction of elastic staple fibres and the reached corporal region. As the punctórios wounds, still that in lesser intensity, if they deform and if they become lightly oval. When, the projectile reaches the victim obliquamente, the orifice if it shows elliptical, prolongated in the dependence of the penetration angle. It can also reveal atypical in the rebound cases or when two successive projectiles reach the same point in the skin and still in the hypothesis of the bullet To have lost its force of propulsion (lost). Exception of great practical importance is observed in the excessively next shots, where the expansion of the gases dilacera the fabrics (fact less rare of the one than if imagines). However, what if it usually finds, it is a regular, circular or oval orifice of clear contours. Size: The entrance orifice is usually lesser of that the bore of the projectile that produced it and with it keeps direct ratio. The examination of the orifice suggests, with good approach, the bore of the vulnerante bullet. Also she is necessary here to except that the very next detonation makes exception and frequently gives to origin the bigger orifice of the one than if waits. Frequently its diameter is lesser of that the exit orifice. However certain caution is necessary, therefore this comparison (with the exit), á times, induces the error. Edges and zones: Skirting the orifice of entrance of the projectile, we find the calls edges and zones. Edge of bruise: When penetrating of the projectile, the invagina skin if as a glove finger and if breaches. Due to difference of existing elasticity between the epidermis and derme, a escoriada, contundida edge is formed. Edge of I dry: The projectile comes turning on its proper axle (movement of rotation necessary to guarantee the direction of the detonation) and coated with impurities proceeding from the powder and the ways previously crossed. As the fabric organic is elastic, adheres to the sidewall of the bullet that, for attrition, it goes leaving glue in the tunnel for she herself dug these impurities brought of the exterior. Of this form the clean projectile if or if dries forming the edge of dries. Zone of tattooing: Also if it calls true tattooing, for not being removable: it has incrustation of granules and poeiras that follow the projectile. It is observável in next detonations. Zone of esfumaçamento: Also called zone false tattooing, therefore simple powder deposit occurs incombusta and impurities, easily removable. II - Orifice of exit To the time of the exit, the projectile presents diverse characteristics of the ones of the entrance: lesser kinetic energy, loss of the impurities in the passage and acquisition of organic material, bigger dilacerante capacity of that armor-piercing and eventual change of direction. Consequently, it is of if waiting that the exit orifice is diverse of the one of entrance in its particularitities. However, nor always the things are simple and schematical. If to appear, in the exit, a bruise edge and to occur entrance proximity, already will not be so easy thedifferentiation enters both (entered and exit). Also, if the projectile before penetrating in the organism will have suffered rebound, characteristics of the exit could be gifts in the entrance. The differentiation, however, temgrande importance, therefore can supply subsidies the study of the direction of the detonation, of high value in the study of the legal nature of the lethal event. In a skill simple notation is not acceptable: orifice of entrance or orifice of exit. It is essential that the examiner proceeds the minute description from the characteristics of both orifices (if to exist). Of this form one reanálise will be viable, exactly after the burial of the corpse.
