    Study Notes

    First Responders Overview

    • First responders include patrol officers, firefighters, and emergency medical personnel.
    • Their primary duty is the preservation of life during emergencies.

    Scene Arrival and Responsibilities

    • First responders are typically the first to arrive on the scene of an incident.
    • Before entering a scene, responders must ensure they have the legal right to do so.
    • Upon arrival, they must maximize safety, remain observant for evidence, and guide EMS to the injured.
    • Officers should use indirect pathways to reduce scene contamination.

    Crime Scene Management

    • A key responsibility is to secure and preserve the crime scene and evidence.
    • The concept of "mechanical loss" refers to the loss of evidence due to life-saving efforts.
    • Evidence must be protected until all physical evidence is documented and collected.
    • The first officer on the scene must attempt to "freeze" the scene by removing witnesses and suspects.

    Perimeter Establishment

    • The outer perimeter is the physical boundary of the crime scene.
    • Upon identifying boundaries, a perimeter should be established to distinguish what is and is not a crime scene.
    • The most common method for setting up a perimeter is using crime scene barrier tape.
    • Over-defining an area is preferred to ensure clarity in crime scene delineation.

    Levels of Containment

    • Multi-level containment is the most effective method for ensuring crime scene integrity.
    • Three levels of containment exist:
      • The outer perimeter, which accommodates medical personnel.
      • The second level, which includes the area for police and emergency personnel.
      • The innermost perimeter, which defines access to the specific crime scene target area.

    Command Post and Control

    • The command post, or "incident command," coordinates on-scene activities.
    • Only individuals actively involved in processing the scene should enter the strictest perimeter; unauthorized access compromises evidence integrity.
    • Every person entering the crime scene poses a potential risk to evidence, even unintentionally.

    Additional Concepts

    • Locard's exchange principle posits that trace evidence is always found at a crime scene and on every individual present.
