Crime scene management skills are an extremely important component of an investigation because evidence that originates at the crime scene will provide a picture of events for the court to consider in its deliberations. Locard’s exchange principle argues that during the commission of a crime, evidence transfer occurs between the victim, suspect, and scene. In this paper, you will identify the key elements of crime scene management, the function served by each, as well as repercussions of allowing a scene to become contaminated or not establishing a solid chain of custody. Support your paper with examples from this week’s required material(s) and/or a minimum of three other scholarly or credible resources and properly cite any references.Prior to beginning work on this assignment, please review the following:From the text:Chapter 3: Digital ForensicsChapter 6: Trace and Materials EvidenceFrom the free, downloadable resource at the web page Crime Scene Investigation Guide (Links to an external site.): Section C: Processing the SceneFrom the free PDF copy at the web page Strengthening Forensic Science in the United States: A Path Forward (2009) (Links to an external site.): Chapter 5: Descriptions of Some Forensic Science DisciplinesThe video Evidence and Forensics: Due ProcessFrom the video Forensic Science in Action: From Crime Scene to Courtroom:Segment 1.
