The type of physical evidence that you are referring to is commonly known as “trace evidence”. Trace evidence encompasses any material and substances which are left behind or recovered from a crime scene or victim, including articles and materials which may aid in determining the identity of the perpetrator or the circumstances under which the crime was committed.

Examples of trace evidence include fibers, hair, fingerprints, blood, DNA, shoe prints, tire tracks, glass, and soil. These materials can be highly valuable in helping investigators to reconstruct the events of the crime scene and identify key pieces of information, such as the type of weapon used or the identity of the suspect.

Forensic scientists use specialized methods and techniques to collect, analyze, and interpret these types of physical evidence. The findings of these experts can often make or break a criminal trial and provide crucial evidence to support the prosecution or defense’s case. Trace evidence, therefore, is a vital component of criminal investigations and plays a critical role in helping to bring justice to victims.
