Forensic science is the use of different sciences such as physics, chemistry, biology, and computer science. Forensic science helps law enforcement obtain a better understanding of how different types of evidence, such as blood splatter, fingerprints, and shell casings, found at the crime scene can play a role in the investigation (Forensic Sciences. National Institute of Justice). Forensic science is very important in the criminal justice system by backing up information based on science through the way that the physical evidence is analyzed. During an investigation, law enforcement collects the evidence is or from a person. It is then sent to a crime lab to be analyzed. After the results are found, that evidence is then presented to the courts. Each crime scene is very different (Forensic Sciences. National Institute of Justice). …show more content…

One of the first used pieces of forensic science used was fingerprinting. They were used by the ancient Chinese to classify many business documentations. In 1892, Sir Francis Galton was the first person to set up a system to manage fingerprints. Then in 1896, Sir Edward Henry, who was a commissioner for the Metro Police in London, created his own structure to recognize the different patterns in a person’s fingerprints. That system, The Henry Classification System, is what became used worldwide to capture criminal’s fingerprints (Watson, S). As early as 1835 is when the first person was able to use physical evidence from a crime scene to link a bullet to a murder weapon. That person was Henry Goddard. Following that, the use of bullet examination became more defined. Calvin Goddard, who was an American physician, invented the comparison microscope to examine what bullets came from what casings. Then again in the 1970’s, scientist at the Aerospace Corporation in California came up with a new technique to identify gunshot residue (Watson,
