DISCOVERING TRACE EVIDENCE

Instructor: Sharon Plotkin, EDD, CCSI
Course length: 32 hours


Trace evidence is defined as minute quantities and applies in the forensics field and Locard’s Exchange Principle which refers to the transfer of material of physical evidence that is small (Ogle & Plotkin, 2018). Locating, documenting and examination of trace evidence requires instrumentation for these minute pieces of evidence. Despite the challenges of trace evidence in linking specific individuals to crime scenes and one another through individual characteristics, the importance of class evidence is its ability to clear or exonerate suspect quickly and effectively.

The purpose of this 4-day Discovering Trace Evidence workshop is to introduce attendees to the importance of trace evidence such as hair, fibers, soil, paint, accelerants, glass and gunshot residue in crime scene investigations and the ability to successfully locate this evidence through tools such as alternate light sources, document this evidence through advanced photographic techniques and effective collection for submission to the lab for analysis. Power points, lectures, interactive activities, and many hands-on labs will be implemented throughout the workshop to ensure all objectives are met.
 
LEARNING GOALS:  At the completion of this 4-day workshop, attendees will be introduced to the importance of trace evidence as valuable minute evidence on crime scenes, and the tools and equipment necessary for the documentation and collection of this evidence.
