Investigating a Crime Scene On TV shows like "CSI," viewers get to watch as investigators find and collect evidence at the scene of a crime, making blood appear as if by magic and swabbing every mouth in the vicinity. Many of us believe we have a pretty good grip on the process, and rumor has it criminals are getting a jump on the good guys by using the tips they pick up from these shows. But does Hollywood get it right? Do crime scene investigators interview suspects and catch the bad guys, or is their job all about collecting physical evidence? In this paper, I’ll examine how a crime scene investigation really takes place. When working a crime scene there are many steps that must take place in order for any investigation to hold up in court. A proper investigation can take hours, but the end result can lead to a conviction of the guilty and justice for victim’s families. The first officer at the crime scene should do everything they can to keep all evidence in its original state. The crime scene must be blocked off immediately to avoid any contamination or loss of evidence. Boundaries should be established for each area of the scene that needs to be secluded. This will include any paths of entry or exits and areas where evidence has been discarded or located. All areas of the crime scene should be blocked off using tape, ropes, or traffic cones. If the crime took place indoors, a single room can be blocked off depending on the place of the crime and where it occurred. Police barricades and guards can help with securing the scene as well. This is a good way to monitor the area to make sure no unwanted people get through and cause loss of evidence. This will include officers that are not involved in the case, neighbors and the family of the victim. Securing the crime scene must be done in a timely
