What is the purpose of a crime scene investigation?

The purpose of a crime scene investigation is primarily to gather physical evidence and understand the context of the crime. This involves meticulously examining the scene to collect items such as fingerprints, DNA, weapons, and other materials that may aid in reconstructing the events that transpired. Understanding the context is crucial as it helps investigators determine how the crime was committed, the sequence of events, and potentially the motive behind the crime.

This process lays the groundwork for further developments in the investigation, including identifying and apprehending suspects based on the evidence collected. Gathering physical evidence is a critical step because it serves as the foundation for building a case that can be supported in a court of law. This methodical approach allows law enforcement to establish facts surrounding the crime rather than solely relying on witness testimony or assumptions.
