Sequential Processing of Documents for Fingerprints - A Technology Transition Workshop

The purpose of this technology transition workshop is to provide the student with an understanding of sequential processing for crime scene exhibits in general, and documents in particular. An identification specialist cannot know in advance, the unique combination of fingerprint components present in the exhibits that will challenge him/her. Nor can the identification specialist know which impressions will be crucial to a case. In many investigations it is essential to target as many potential components of fingerprints as possible to ensure that nothing is missed. This class will include lecture, demonstration and hands-on activities to illustrate and practice the concepts presented. During the lecture portion of the workshop, participants will learn the rationale for sequential processing of paper exhibits based on the wide range of potential target components of finger deposits. The need to triage exhibits by incorporating their condition and history into the analytical decision making process will be highlighted. During the laboratory portion of the workshop, participants will have the opportunity to practice triaging mock paper exhibits to ensure that all reagents are used appropriately during processing.
