Crime scene investigation (CSI) is a lot more complicated than what you might see on television. In many mystery shows, the investigators show up, take a few photographs, and then return to the lab to conduct experiments. Although these shows make for great entertainment, they don’t depict the planning, time, and effort that go into real crime scenes. Every crime is an event that must be managed and reconstructed through isolating the area, documentation, and organization. To accomplish this task, crime scene investigators must follow certain procedures.
Keep in mind that the duties of each precinct vary depending on available staff and the scope of the crime. Any illegal activity can involve various departments or organizations such as the local police, forensics experts, or national organizations such as the Federal Bureau of Investigation (FBI). With that in mind, the following procedures are standard across the board and are a basic introduction to what you will learn when you study forensic science in a degree program.
