This one-week (38 hour) course is intended for individuals responsible for collecting latent print evidence at crime scenes and/or processing evidence for latent prints in the laboratory. The course is designed to acquaint students with various techniques used in the development of latent prints, as well as the sequence in which the techniques should be applied in order to achieve the best possible results. The students will participate in practical exercises involving fingerprint powders and lifting techniques, the applicaton of ninhydrin, cyanoacrylate fuming, laser/forensic light source and photographic techniques, and courtroom testimony. The course will also cover laboratory safety, friction ridge formation, latent print constituents, note taking and documentation, packaging and handling of evidence, and latent print evaluation. While they are briefly reviewed, an understanding of basic fingerprint pattern types, fingerprint history, and terminology is assumed. Each class is limited to 15 students.
