This detailed discussion of the comparison and identification of fingerprints covers taking inked prints, classification, the evidence print, the photography of prints and impressions, the basis of the comparison, comparing prints, some comparisons of evidence prints, and reporting and testifying to conclusions.
Abstract
In the chapter on taking inked prints, descriptions are given of the procedures for taking identifying fingerprints and palm prints, and other devices and materials for recording prints are considered. A description of procedures for taking major criminal prints is provided, and sections are devoted to printing problem subjects and printing the decreased. Classification procedures are then described for the various characteristics of fingerprints, palm prints, and sole prints. In the chapter on the print obtained as evidence from a crime scene, attention is given to the latent print, the visible print, and the plastic impression, as well as locating, developing, preserving, collecting and determining the age of evidence prints. Photographing prints and impressions to record what is seen accurately and permanently for future reference and to enhance the appearance of evidence, is discussed under the topics of the camera, film, the use of colored filters, and lighting. The chapter on print comparison considers class and individual characteristics as well as determining identity, orienting the evidence print, locating minutiae, and interpreting tonally and laterally reversed prints. Distortion and overlain prints are also discussed. Photographs and narrative discussion are used in the comparisons of evidence prints. The concluding chapter briefly advises the examiner on how to report and testify on conclusions drawn from scientific analyses. Thirty-eight references and a subject index are provided.
