Bloodstain and Transfer Patterns In 1955, the first meaningful achievement of bloodstain evidence was credited to Dr. Paul Kirk of the University of California at Berkeley (Nordby). First and foremost, blood contains a fluid portion we call plasma. Plasma contains natural segments of erythrocytes, leukocytes, and platelets. The nuclei of the leukocyte (white blood cells) are our source to DNA evidence. Furthermore, blood is similar to common fluids however, blood is held together by powerful cohesive molecular forces that generate a surface tension within each drop and on an external surface (Nordby). Furthermore, investigators have recounted aspects of a crime by the use of bloodstain patterns. Like when it happened, in what area the attack took place, what kinds of weapon or weapons was used on the victim, and where or how close the attacker was to the victim. But how could we have accomplished attainable information from strings? According to forensic scientist’s, the strings themselves are not as substantial. However, they are clearly a form to help investigators and analysts draw a closure in reference to a substance that is often found at a crime scene: blood. In addition, the population has been converted to believe blood samples are used to ID someone through DNA. However, the blood in general, where it settled, how it settled, its consistency, the size and form of the blood globule, or spatter can conclude a lot of meaningful aspects of the offense. In addition, analyzing a blood splatter or pattern is not as uncomplicated as fictional bloodstain pattern analysts. Experts in the specialty oftentimes, agree that it is as much an art as it is a profession. If there were to be numerous victims and numerous attackers, it becomes very complicated. However, an educated forensic bloodstain pattern analyst can generally present important facts that can lead
