Document Summary
Major steps in crime scene investigation: principle reason to examine a crime scene: to apply the scientific method and perform systemic evaluation of the scene and collect and preserve physical evidence to help reconstruct events. It"s important to secure a crime scene as there was likely an exchange of evidence between the suspect and the victim. Does the physical evidence point to illegal human activity: develop a hypothesis. Based on field observations: look for evidence that supports or invalidates the hypothesis, collect and document the evidence. Once a crime has been confirmed: management of a crime scene. Search warrant, review crime limits and roles: processing of a crime scene. Collection and packaging of physical evidence: reconstruction of a crime scene, closing of a crime scene. Second priority is preventing harm to other animals. Scene may contain physical hazards (extreme weather, fire, weapons), chemical hazards (toxic chemicals, pesticides), and biological hazards (blood-borne pathogens, body)
