Forensic Science


Workshop Description: Forensic science, the application of scientific principles to criminal and civil laws within a criminal justice system with the goal toward the establishment of guilt or innocence, has had an enormous impact on the definition and enforcement of the laws enacted to regulate society. This workshop will introduce some of the specialized fields of forensic science and provide the fundamental principles of science and technology upon which they are based. Aspects of forensic science involving the examination of physical, chemical, and biological items of evidence will be explored. This workshop will provide the participants with an opportunity to develop a basic understanding of forensic science and to learn about the application of forensic science to essentially all aspects of undergraduate instruction in chemistry. In the laboratory component, participants gain sufficient experience to incorporate forensic experiments into undergraduate chemistry and/or biochemistry courses. The activities on each day include lecture, discussion, and laboratory exercises which include an analysis of evidence collected at various crime scenes. Day 1: Legal Issues Associated with Scientific Evidence/Processing the Crime Scene. Forensic scientists must have an understanding of the legal system to insure that their actions and results are within the rules of law and are admissible in the courts. Participants discuss the scope of expert investigation and testimony and the law as it applies to the admission of test results in evidence. Trace Evidence. An appreciation will be gained for the analysis of trace evidence including the refractive index of glass, differential staining of fibers and fabrics, development of fingerprints, and thin layer chromatographic (TLC) analysis of inks and other materials. Day 2: Ballistics and Presumptive Drug Detection. This unit will include an introduction to ballistic analysis including comparison of bullets and shell casings. This session also will involve a discussion of a variety of presumptive tests for drugs such as the color tests for drug material and one step screening for drugs in urine. In the laboratory, the participants will compare bullets and shell casings and perform tests for the presumptive presence of drugs in powders and urine. Day 3: Alcohol and the Evidentiary Analysis of Drugs. This session will begin with a discussion of the analysis of alcohol in the blood, breath, saliva, and urine. Continuing with the material from day 2, confirmatory or evidentiary tests of drug material employing FTIR and GC-MS will be discussed. In the laboratory, participants will analyze for alcohol in the breath and saliva and perform evidentiary tests for powdered drug material and drugs in the urine. Day 4: Serology and DNA Profiling. This unit will introduce basic blood typing and extend this fundamental procedure to the more elaborate DNA profiling. Using PCR, gel electrophoresis, and dot blots, the participants will analyze samples of DNA to determine if they have a common origin. Day 5: DNA Profiling. A continuation of the PCR profiling begun on Day 4 to complete the analysis of the samples to determine if they have a common origin. The Forensic Science Scholars community website has its origins in the series of cCWCS workshops in Forensic Science presented by Progessor Lawrence Kaplan at Williams College. Please note: Since this is a "working" workshop that will involve a significant commitment of time during the week, it is expected that, if selected, you will attend by yourself without family members or pets. It also is expected that you will live with the rest of the participants in the dormitory. PLEASE NOTE: it is some distance between the dormitory and the Chemistry Building (where lectures and lab will take place) so plan for a significant amount of walking. The workshop activities will begin with dinner at 6:30 pm on Monday evening. Please plan to arrive in Williamstown by 5:00 pm.
