Document Summary

Physical evidence, any object that can establish that a crime has been committed or can link a crime and its victim or its perpetrator. Secure and isolate the crime scene, the 1st officer arriving on the scene of a crime is responsible for preserving and protecting the area. As additional officers arrive, measures are immediately initiated to isolate the area with ropes or barricades along with guards to prevent physical evidence from being damaged. Record the scene, three methods include: photography, sketches, and notes. Rough sketch, a draft representation of all essential information and measurements at a crime scene. This sketch is drawn at the crime scene. Finished sketch, a precise rendering of the crime scene, usually drawn to scale. Photography: one of each-overview shot, medium shot, close-up shot, and close-up with ruler shot. Computer-aided crafting (cad), software used to reconstruct crime scenes from rough sketches.
