Introduction Forensic science is a discipline in science and law. It involves scientific studies to provide a solution to crime and civil cases (Blackburn 1). Forensic science cuts across all disciplines to include forensic engineering, forensic psychology, pathology and forensic biology.Forensic biology involves living organisms’ studies in criminal cases. The world of justice has been shaped by forensic science taking crime investigations to another level and signifying the progress of modern technology and today the today it covers modern computing, clay fascial reconstruction, autopsy techniques, forensic anthropology, DNA fingerprinting, toxicology and much more (Blackburn 1). This science also depends upon other physical techniques of identification such as analysis of finger prints (finger print developing, identification and finger print comparison) tool mark and firearm identification. In case a forensic investigation has involved shoot outs then the investigation involves ballistic type of investigation. This is the study of the flight pathway of a bullet or the projectile of a bullet, this is called ballistics. This study is mostly applied in crimes. It involves the analysis of the weapons especially those that have been used in firearms. It involves the analysis of bullets and bullet impacts in the crime in question (Craft 20-23). The bullet trajectory includes the progress of the bullet through the barrel of the gun following discharge or detonation and its pathway both through the air and the aim. Tracing the bullet path reveals from what direction the bullet could have been fired, it is an important stage in forensic science investigation (Craft 27). This can be important in investigating route of actions in the crime or catastrophe. History of on Ballistics in Forensic Science The science of firearms and tool mark has evolved over the past 165 years. One of the first references made concerning firearms dates back to 1493 and 1508 where Harold Peterson discusses firearms rifling by Maximillan of Germany. Although here some firearms were riffled –what were of more value in identifying a projectile which had been fired were the helical grooves that were inside the bore which did not occur until the late 19 th century. Between 1835 and 1899 events occurred that were ultimately associated with firearms and tool mark identification. The processes included physical typing, simple observation and determination of sizes and shapes of a projectile (Herrick 55). There were also slots for carrying out experiments. During the period between 1930 and1970, forensic ballistic identification continued to evolve. In USA the scientific crime Detection Laboratory (SCDL) had its operation beginning in Northwest University in the late 1929 till 1930 followed by FBI in 1932. Many other countries also recognized the need to integrate this into their system. This was to be implemented in the existing laboratories or as novel laboratories, hence over the following few years many such laboratories were established and began operation in major cities like Canada, UK, USA and Europe. In the last part of the century (1970-1999) forensic ballistic has continued to evolve with man
