Wound production by ricocheted and destabilized bullets

Abstract:
Bullets destabilized by ricochet or as the result of an impact with some intervening object experience a yawing to tumbling motion in flight. As a result, they often produce atypical entry wounds, but, as will be demonstrated in this article, this is not a certainty and such bullets can produce normal-appearing entry wounds. It is these wounds that are more difficult to recognize as the consequence of a ricocheted or deflected bullet at the time of autopsy. With few exceptions, ricocheted or deflected bullets also acquire characteristic damage and trace evidence inclusions that often survive the wound production process. A careful inspection of such bullets at the time of recovery will usually reveal such ricochet damage. Moreover, the instability of ricocheted bullets alters their soft-tissue penetration behavior in 2 possible ways. Destabilized full-metal-jacketed bullets will typically penetrate less than direct strikes by the same bullet. Destabilized jacketed hollow-point bullets will often fail to expand and subsequently penetrate more deeply than direct shots with the same bullet.

Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...
Impact
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...
Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
