Documenting crime scene conditions can include immediately recording transient detail such as lighting (on/off), drapes (open/closed), weather, or furniture moved by medical teams. Certain evidences such as shoe prints or gunshot residue is fragile and if not collected immediately can be destroyed or lost. The scope of the investigation also extends to considerations of arguments which might be generated in this case (self defense suicide) and documenting conditions which would support or refute these arguments. In addition, it is important to be able to recognize what should be present at a scene an d what should not (victim's vehicle/wallet) such as objects which appear out of place (ski mask) which might have been left by the assailant. It is also important to determine the full extent of a crime scene. A crime scene is not merely the immediate area where the body is located or where an assailant concentrated his activities but can also encompass a vehicle and access/escape routes. Although there are common items which are frequently collected as (evidence fingerprints, shoe prints or bloodstains ), literally any object can be used as physical evidence. Anything which can be used to connect the victim to a suspect or a suspect to a victim or crime scene is relevant physical evidence. Using the "shopping list" approach (collecting all blood stains, hairs, or shoe prints in recognizing the best evidence. For example, collecting bloodstains under the victim's body can be excellent physical since it can be directly tied to a matchbook found in a suspect's pocket. Since a weapon or burglar Õtool is easily recognized as significant physical, it is frequently destroyed by the perpetrator. Sometimes the only remaining evidence is microscopic evidence consisting of hair fibers, or other small traces the assailant unknowingly leaves behind or takes with him. Although this evidence is effectively collected when the clothing of the suspect or victim is taken, protocols (involving tape lifts ) should be in place to process nude bodies so as to not lose this fragile evidence.
