This course was designed to continue to grow the student’s knowledge base as we dove head-long into the science behind the uniqueness and persistence of friction ridge skin. We covered embryology, histology, glands, secretions, and wound healing in an attempt to grow the confidence of the students in the science behind their conclusions. We also spent a significant amount of time on the history of fingerprints, ridgeology theory and technique, searching smart, orientation, target group selection and analysis phase of ACE-V. The students worked through Comparison Exercise B which contained 80 latent prints and an additional comparison exercise that contained 10 latent prints.
