What should a first responder do if they determine that a crime has been committed?

When a first responder determines that a crime has been committed, the primary responsibility is to document and retain evidentiary value. This is crucial because evidence must be collected in a careful and methodical manner to ensure its integrity and admissibility in court. By properly documenting the scene, including collecting physical evidence, taking photographs, and making detailed notes, the first responder plays a vital role in the investigation process. This documentation helps establish a timeline, provides context for the investigation, and supports any subsequent legal proceedings.

Taking actions that compromise the integrity of the scene or the evidence, such as intervening immediately or leaving the area, could jeopardize the investigation. Safety is important, but it should not override the necessity to protect and preserve evidence. Therefore, maintaining the evidentiary value is paramount for any law enforcement protocol following the discovery of a crime.
