It is a multidisciplinary science that uses principles from various fields, such as biology, chemistry and physics, to analyze evidence and provide insights in criminal investigations. In this essay we will explore its importance. Forensic evidence can be defined as the information at a crime scene, such as DNA, blood, and body tissues found at a crime scene, among others. Forensic science uses chemistry to analyze poisons and drugs, physics to conduct accident investigations, and biology to conduct DNA profiling. Through forensic science, the criminal justice system is also able to analyze physical evidence Peterson, 2010. These include elements such as shoe prints, fingerprints and handprints, blood spatter patterns and fiber samples present at crime scenes. Another type of physical evidence revolves around the weapons used by the suspects.
