Forensic scientists perform the technical work of analyzing and interpreting the different types of evidence from a crime scene using scientific equipment in a laboratory to guide the investigation, allow detectives to effectively narrow their work, and ultimately hold offenders accountable You are also strongly encouraged to review the recommended sources, which may further support this discussion forum. As an intern at a Forensic Crime Scene Response Unit (CSRU) and as part of your duties, the unit manager occasionally asks you to develop presentations. This week the local chapter of the American Bar Association has requested a presentation for their quarterly professional development luncheon. You will develop a short presentation about the evolution of and impact the scientific analysis of evidence has had on both criminal investigations and at trials. You must address admissibility issues resulting from case law such as: Frye v. United States (1923) Daubert v. Merrell Dow Pharmaceuticals, Inc. (1993) Melendez-Diaz v. Massachusetts (2009) Crawford v. Washington (2004) The file for the presentation should be attached or embedded in your post for your peers to review, and be sure to link your screencast recording. The class has been separated into five topics. You will be assigned a topic by your last name to complete this presentation. The breakdown is as follows if your last name begins with the corresponding letter: M through R: Digital evidence Your presentation must address the following elements: Describe the history of the scientific processes used for your category of evidence. Describe how the science in your area has evolved. Explain the current standard for analysis included in this category. Identify any shifts in how the evidence or science is perceived. Explain how the results might be used in a criminal investigation. Explain how the results might be used at trial. Identify any challenges to having the evidence admitted at trial, specifically focusing on case law that has established standards for scientific analysis and admitting the evidence at trial. Your presentation should have a minimum of five content slides (excluding cover and reference slides) and be at least three minutes long. Support your presentation with examples from this week’s required material(s) and/or other scholarly resources and properly cite any references either in the text, on bullet points, or in the notes section. You must use at least one scholarly or credible, professional resource to support your presentation. The presentation must include a cover slide, and a references slide for sources cited in the body of the presentation.
