Murder Call

The pieces of evidence are crucial part of the case, it indicates what happened, how violent the act was and what was missing, damaged or left behind the crime scene. Many pieces of evidence do not indicate the violent and brutal assault. A single word or a single note may be perceived as a serious threat. Something One will try to defend against. The fraud is omnipresent on daily basis, there are tools and means how to protect One from harm. The number of pieces of evidence found at the crime scene embrace death, drugs, and disaster; bodies and blood, guns and glass; semen and saliva; bullets, bombs, and bite marks; tool marks and trauma; poisons, homicides, safe paint, footprints, fingerprints and psychoses.

Asphyxia and Strangulation  In case of suicidal deaths the most common one is strangulation, the deaths caused by asphyxia. In this article asphyxial deaths will be explained. These are caused by the failure of cells to receive or utilize oxygen. The deprivation of oxygen can be partial (hypoxia) or total (anoxia). The classical signs of asphyxia are visceral congestion, petechiae, cyanosis, and fluidity of blood. These are nonspecific and can occur in deaths from other causes. Visceral congestion is due to obstructed venous return and capillovenous congestion. We can differentiate two most common hemorrhages;  petechiae are hemorrhages produced by rupture of small vessels, predominantly small venules. Rupture is caused by sudden over distention of the vessels following abrupt increases in intravascular pressure. Cyanosis death is  nonspecific and caused by an increase in the amount of reduced hemoglobin. It does not become observable until at least 5 g of reduced hemoglobin

The injury may be only a minor bump on the skull or a serious brain injury. Head injury can be either closed or open (penetrating).

The head injuries are the most common ones, and at the same time, the most dangerous. Innocently looking trauma may lead to a demise, though, a very severe looking  one may be come away unscathed from (a blow/ accident). It all lies in a sheer luck, sometimes. The head and brain trauma might be categorized according to the mechanism it is done: -           impact injuries; -           acceleration injuries; declaration injuries which divides into subdural hematomas and diffuse axonal injuries. The impact injuries are ca
