Ashford University Technical Work of Analyzing and Interpreting the Different Types of Evidence Presentation – Description
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.

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)
****** Write speaker’s notes as a script at the bottom of each slide are required.*****
Topic: Fingerprints
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.
