Introduction To Forensic Science

Forensic science is the application of many other sciences including physics, chemistry, biology, computer science, and engineering to matters of law and order. Forensics science is used by investigators to help understand what happened at a crime scene. Every single part of the crime scene is analyzed to find the smallest bits of evidence. Forensic science can help investigators to understand how blood spatter patterns occur, find out who was at the crime scene, when the crime occurred, and who committed the crime. Forensic science is a very important part of the justice system because it provides scientific facts based on hard evidence. In a typical crime scene investigation, material evidence will be gathered by the investigators. Then the forensic scientists will analyze this evidence to provide a piece of scientific-based evidence to be presented in court. Each type of material evidence must be collected in a different fashion to ensure that the evidence remains as intact and uncontaminated as possible.

Forensic science helps in finding out clearly the crime, the criminal and the motive behind the crime. “Forensic science is a versatile and enormously powerful tool in the investigation of a crime.” After the occurrence of the crime, different types of shreds of evidence may be found at the crime scene. forensic science is a critical element of the criminal justice system. Forensic scientists examine and analyze evidence from crime scenes and elsewhere to develop objective findings that can assist in the investigation and prosecution of perpetrators of crime or absolve an innocent person from suspicion.
