What is evidence primarily used for in investigations?

Evidence is primarily used in investigations to establish connections between individuals and specific locations, events, or devices. This function is critical because it helps investigators construct a factual basis for the case, supporting claims made during the investigation and potentially leading to an arrest or prosecution. By linking a suspect to a crime scene or to criminal activity, evidence can significantly influence the direction of an investigation and the outcomes of legal proceedings.

In contrast, while creating a narrative of events, identifying witnesses, and providing background information are important aspects of investigations as well, they are not the primary function of evidence itself. The core value of evidence lies in its ability to substantiate claims and demonstrate relationships that are essential to understanding the context and details of a crime. This foundational role of evidence is what makes it paramount in building a case within the judicial system.
