Document Summary
Evidence: anything that can be used to proved an assertion. Observations (weather, lights on/off at crime scene: used to tie suspects to scenes and victims. What could be physical evidence: any and all objects that can. Establish that a crime has been committed. Link crime-victim, crime-perpetrator: to be effectively, its presence first must be recognized at the scene. Reconstruction: the more physical evidence is recovered. More likely a theory of what happened during a crime can be established. Must be selective: selectivity based on collector"s knowledge of lab"s techniques, capabilities, limitations. Lacking this knowledge can lead to evidence being overlooked or collected improperly. Could in theory collect every single item in the room. Collect in a manner that is most useful. Search for evidence: thorough and systematic, technique governed by the area that has to be searched. Collecting evidence: try and keep evidence in original condition. Less handling, the better: separate everything.
