Abstract

Forensic evidence is not always perfect. Often times a sample of DNA at a crime scene is degraded or much too small to be analyzed. Blood spatter may be cleaned up before police arrive. Fingerprints may be latent and nearly invisible to the naked eye. How do forensic professionals use these imperfect samples to build a case? They must find a way to chemically enhance and amplify each of the samples so they are suitable for analysis. This seminar will discuss some of the techniques used by forensic professionals to overcome imperfect evidence. We will also discuss how each technique works, the benefits, and the downfalls involved. By the end of the seminar, these imperfect situations will no longer be seen as obstacles, rather, just another step in the process of forensic analysis.
