Analysis of Distortion in Latent Prints

This two-day workshop focuses on the Analysis phase of the ACE-V (Analysis, Comparison, Evaluation, Verification) process. During the Analysis of a latent print, the analyst is gathering information. The analyst is detecting the features they may use during the comparison, setting tolerances for variation in appearance, and determining the utility of the print. The ability to detect these features in the latent print and the establishment of tolerances for variation in appearance are inextricably linked to the distortion present in the latent print.


Essentials of Latent Print Examination:  Establishing Admissibility

There are two primary spheres of foundational knowledge that support the latent print discipline: 1) science demonstrating the discriminating power of friction ridge impressions and 2) science demonstrating that trained analysts are capable of providing valid conclusions. While many analysts receive the knowledge portion during training, they often struggle articulating the concepts for the trier of fact.  During this intense five-day course Alice will review key pieces from both spheres that can be used to support testimony and mentor participants on the presentation of these concepts in the courtroom. A few comparison exercises are provided during the week to reinforce the academics and a court case study, woven throughout the week, will illustrate the real-world application of the methods presented. The content of this course is organized into four blocks that logically build on one another: 1) Empirical Observations and Tacit Knowledge, 2) Measuring the Discriminating Power of Fingerprints, 3) Developing Expertise, and 4) Expert Performance.


Power Palm Prints

This two-day workshop is dedicated to the friction ridge skin of the palms.The palms have regional variation in the crease patterns and ridge flows that can be exploited to determine the anatomical region and distal orientation of latent prints. Additionally, the patterns on the hands have a distribution within the population that informs the rarity of level one features during the ACE-V (Analysis, Comparison, Evaluation, and Verification) process.
