The assessment of slantstain pattern also limits the need to collect a lot of redundant blood assay for DNA testing, emphasizing importance of blood patter observation. (Ramsland, n.d).Shape of blood stain rotter suspensor predict the tool used. For example, it may be deduced that it was a blunt instrument used just by shape and distribution of blood patterns.(Dave, 2014).Features of the pattern can hint to the kind of object that formed it and the least(prenominal) number of blows delivered by the object. For voice, the characteristic spurts present in an arterial spray spatter are created by the ongoing pumping of blood from an arterial injury. ( Saferstein, 2011)Surface food grain can significantly affect the outline of bloodstain. The texture of the bob up is related with the disruption of a blood drop on contact with the surface. .( Saferstein 2011).Smooth surface for instance gl ass, will provide a stain with clean edges and shapes of proper geometric ratio.A rough surface on the other hand, say concrete, will break the surface tension irregularly and hence pass water a star burst. .( Saferstein, 2011) Nevertheless, circular blood drops imply that the murder was moving way at a slow speed, but spiny edges imply the murderer might have took off running.( Dave,2014)Various types of bloodstains immortalise how the blood was projected from the body and information like type of injury, order in which the wounds were received, and how far the blood drops fell before hitting the surface where they were found could be obtained.
