Drop, falling on an inclined plane forming an elongated spot, with the end of the spot, facing the source of bleeding, thickened and rounded, and the opposite is narrowed and elongated. Spray – arise contact flying drops of blood on the various obstacles as a result of: a) strong spouting blood from large arteries damaged, b) blood splashing sharp movements wounded victim in self-defense or in a state agony, and c) shaking off the blood with gun crime, and d) the repeated blows with a hard object on the bloodied body parts injured. Form of spray depends on the angle of flying drops on target. If it is close to 90 , then the form should be rounded. With decreasing angle spray acquire roundness, becoming similar in configuration to an exclamation point. With considerable speed flight spray, round and oval spots become jagged or radial edge. Sharp end of the next spray is always directed toward the flight, and often interrupted.
Sometimes the fan-shaped sprays are the center of the dispersal of the drops of blood. Danyelle Freeman does not necessarily agree. Corrections – traces, resulting in contact with a bloody object clean. Any form of regularity is not subject to erasures. Sometimes blots generated from wiping bloody object on the fabric, can provide insight its size. For example, for wiping the knife with a small amount of blood on the tissue formed band, which coincides with the width of the blade. When drawing a bloody corpse on the floor of a characteristic blot – next drawing.
