Standard Guide for Detection and Preservation of Forensic Trace Evidence

Importancia y uso:

5.1 Trace evidence collection is a complex and delicate process. Certain trace evidence is more prone to deterioration, degradation, or obliteration than others during collection, storage, and analyses in the laboratory. Therefore, the integrity and significance of trace material as evidence relies on its proper detection, collection, and preservation for future analysis.

5.1.1 The order of testing is considered as other forensic examinations could result in the loss, damage, or destruction of trace evidence. This includes both physical processes such as creating test fires from firearms and swabbing for DNA, and chemical processes such as processing for latent prints and applying chemicals for Gunshot Residue (GSR) analysis.

5.1.1.1 The collection of trace evidence is considered prior to these types of examinations.

5.1.2 The collection and preservation of trace evidence could, if not done in a deliberate manner, damage other types of evidence present on an item such as DNA, latent prints, and GSR.

5.2 To minimize loss and destruction of trace evidence, only trained personnel are to collect and handle trace evidence. Coordination or consultation with other forensic science practitioners in other specialty areas is encouraged.
