Course
Description |
|
Explains the history, biology, and basic principles of
friction ridge analysis. Properly recording, processing, documenting,
collecting, and preserving latent print evidence will be discussed. Students
will also be introduced to the Automated Fingerprint Identification System
(AFIS) and the analysis, comparison, and evaluation of latent prints. |
