Forensic scientists study the details of a crime and report their findings to a court of law. To do this, forensic scientists perform physical and chemical analyses on criminal evidence submitted by the police or other law enforcement agencies. The physical evidence may be found at the scene of a crime, on a victim, or both. Regardless, forensic scientists use a variety of problem-solving methods, mathematical principles, complex instruments, and microscopic examining techniques to explain the intricacies of each piece of evidence from a case. Some forensic scientists work in laboratories, while others conduct their analysis at the scene of the crime.
After analyzing the physical evidence, forensic scientists draw links between the suspect, the victim, and the crime scene. For example, they may use physical evidence to determine the make, model, year, and even the identity of the owner of a car associated with a crime. Then, they explain the results of their analysis and describe the methods they used to reach their conclusion in a report, which they will cite while providing testimony in court. Throughout this process, forensic scientists ensure that their examination of physical evidence is complete, tests are administered correctly, the data interpretation is accurate, their report is clear and concise, and their testimony is truthful.
