Finding Latent Evidence with Chemistry and Light

Course Description

The purpose of this four-day seminar is to enable the student:

  • To identify the best technique, or series of techniques, for developing the maximum evidence.
  • To understand and exploit fluorescence as a powerful detection strategy, using a range of Forensic Light Sources.
  • To record impression evidence faithfully and accurately.
  • To prepare and use the chemical reagents safely in a laboratory environment.
  • The student will learn about lasers and light sources as key forensic technologies, as well as the principles behind luminescence detection of evidence.
  • Techniques targeting tapes (adhesive side), blood prints on porous and nonporous surfaces will be featured.
  • The student will learn how to use multiple techniques in the correct sequence on many surfaces for maximum results.
  • The student will learn conventional, atypical, and digital photographic techniques for extracting the clearest and most useful images.
  • This course will feature hands-on sessions in exhibit processing and photography, as well as an examination and certificate of completion. 

Target Audience

Crime scene technicians, detectives, laboratory analysts, and others who process evidence in a laboratory environment, who want to understand and exploit fluorescence as a powerful detection strategy using chemical reagents and a range of Forensic Light Sources

Must Bring to Class

  • Students must bring lab coats or other protective garments and wear old clothing on lab days.
  • No open-toed shoes can be worn in the laboratory.
  • All students are strongly encouraged to bring a digital camera (digital SLR preferred) with a macro lens and tripod to enhance the learning experience during this class – it is not required for attendance but is strongly encouraged.
  • All types of standard digital media should be able to be used by the instructor to critique the work
