Blood Pattern Analysis is a forensic science that uses visual pattern recognition to handle the physics of blood and to identify the blood streaks left at the crime scene. It is used to clarify the crime scene reconstruction, such as homicide, suicide, accident cause of death, identifying the area where the criminal could leave his DNA sample behind. The crime scene can be traced back to the past few centuries using the documentary description of the blood shape, but in 1955 the Samuel Shepherd incident stimulated the progress in this field.
The basic course of blood type analysis is the blood type basic analysis course. It is taught in many government agencies and private institutions. Curriculum standards are developed by the International Blood Group Inspection Analysts Association (IABPA) for the following purposes. Investigators, criminal site technicians, forensic engineers, other criminal and medical legal investigations and persons involved in the crime scene. This course aims to develop the foundation of the blood group analysis method.
Blood type analytical science solves practical problems by applying scientific knowledge of other fields. Blood pattern analysis utilizes biology, chemistry, mathematics, and physics as scientific fields. As long as the analyst follows the scientific process, this applied science can generate powerful evidence that makes it an effective tool for researchers (Fisher, 2003). Blood is a partially alkaline liquid composed of water, cells, enzymes, proteins, and inorganic substances. It flows through the entire vascular system and carries nutrients, oxygen, and waste products.
Blood group analysis is a technique in the field of forensic science. This technique of using blood as evidence is not new; however, the application of modern science has made blood analysis more reliable (Wikipedia). The arrest of criminals and criminals will not be a problem as long as advances in current technology and DNA analysis become available to law enforcement agencies (Wikipedia). Research on blood pattern analysis of forensic science solves many practical problems by applying scientific knowledge of other fields
Blood analysis is very important in a variety of situations. For example, in forensic medicine, analysis is very important if blood type can be obtained. BPA (blood group analysis) can clearly define the location of the victim or attacker by determining the behavior of one or both parties in many cases. Individual bloodstains caused by blooddrop distribution are all called splash patterns. Splash patterns are usually more emphasized than other bloodstains, but they basically include class functions. The class function identifies or separates other classes from other classes. (Wonder, 2001) may establish an unlikely scenario to determine whether a victim, a witness, or an attacker accurately describes what happened. Many courts across the country strictly adhere to the value of BPA and scientific credibility. Litigation information is available upon request. (Bevel & Gardner, 2001)
