Crime Scene
Actions taken at the outset of an investigation at a crime scene can play a pivotal role in the resolution of a case. It is important for the initial responding officer to be observant when approaching, entering, and exiting a crime scene. The procedures associated with crime scene evaluation include: identify scene dimensions – locate the focal point of the scene; establish security – tape around the perimeter; create a plan and communicate – determine the type of crime that occurred; conduct primary survey – identify potential evidence and capture photographs and take notes; document and process scene; conduct secondary survey; and record and preserve evidence. How do you collect and preserve physical evidence? Collect evidence correctly, preserve each specimen separately, use and change gloves often, avoid coughing or sneezing during the collection, use appropriate tools such as cotton-tipped applicators, separate paper bags, and envelopes to prevent cross-contamination of samples.
