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.
