What does "trace evidence" refer to in forensic terms?

Trace evidence refers to small quantities of materials that are transferred from one location to another during the commission of a crime. This can include various types of substances such as hair, fibers, soil, glass, or paint, which, though minute in size, can provide significant clues linking a suspect to a crime scene or victim. The analysis of trace evidence is essential in forensic science because it helps to establish connections through careful collection and examination processes.

By focusing on trace evidence, forensic experts can piece together a narrative of the crime, revealing how and when the offender might have interacted with the victim or the crime scene. The identification and comparison of trace materials can also help corroborate witness statements or establish timelines in a case.
