Abstract
This paper explores the methods of latent fingerprint discovery the finding and retrieving of latent prints from a crime scene. Here we will review how to find a latent print using alternative light sources and what those light sources are. We will also review the surface characteristics of evidence and the purpose of sequential processing. Making sure that the rights steps are taken when processing fingerprints so such evidence is not destroyed. Also we will go over the fingerprint development techniques, each of their uses and processes in finding and retrieving the fragile prints such as brush and powder, superglue fuming, small particle reagent, machine paper technique and others. This paper examines the techniques taught from Mark R. Hawthrone and Ross M. Gardner teachings and training.
The Methods of Latent Fingerprint Discovery
Finding and Retrieving Latent Prints from a Crime Scene
Everything we touch leaves a mark, an invisible unique, one of a kind pattern. These patterns are so unique that no two people have the same prints, not even identical twins. The patterns known as fingerprints identify who we are, where we have been, and what we have touched. These unseen prints we leave behind are called Latent prints, and for crime scene technicians they are the most fragile and valuable piece of evidence linking a person to a crime. The methods for finding and retrieving these prints are important. To take a wrong step and lose the print could cost you an important case. Here I will help you understand the methods used in finding and retrieving latent prints from a crime scene.
How to find a Latent Print
There are a few ways that crime scene technicians use to make a print visible. Here I will list the equipment used in finding and retrieving latent prints. In choosing which
