Forensic methods and techniques of developing latent fingerprints on different surfaces
Fingerprints have been an important contribution to the forensic sciences since the researches made first by Francis Galton and then by Juan Vucetich. Some time later, Henry Faulds established that individuals leave their fingerprints in a non-visible way, in every element that they manipulate or surface with which they have contact. After this, different methods of latent fingerprint development began to be implemented in the crime scene. This discovery created a new discipline of Criminalistics, dedicated to the study of the development of fingerprints, and from that time to today, different methods are used: physical or chemical, depending on age of the fingerprint and the surface where it is found. ADN Criminalística will dedicate this exhibition to the development of fingerprints by physical methods describing the properties of the tools currently used, and its usefulness according to the characteristics of the different supports that contain it.
