Subject: Security Education
Class: Junior Secondary School 2 (Age 13)
Week of the First Term
Topic: Crime Scene Management
Subtopic: Tips Required to Secure a Crime Scene
Instructional Objectives
At the end of the lesson, pupils should be able to:
- Identify the key steps to secure a crime scene to preserve evidence.
- Explain the importance of not disturbing a crime scene before authorities arrive.
- Demonstrate proper techniques for reporting and managing a crime scene until help arrives.
Entry Behaviour
Pupils should already have an understanding of common crimes and the importance of reporting them. They should know what a crime scene is and have learned about government agencies involved in crime control.
Instructional Materials
- Visual aids showing crime scene management procedures (e.g., diagrams of secured areas)
- Sample crime scene tape and cones to demonstrate securing a scene
- Video clips showing real-life examples of crime scene management
Content
When a crime is committed, the area where the crime occurred is known as a crime scene. Proper management of a crime scene is essential to ensure that evidence is preserved for investigation and prosecution. Disturbing a crime scene can compromise evidence, making it difficult for law enforcement to conduct a thorough investigation.

Key Steps to Secure a Crime Scene
- Assess the Scene:
- The first step when arriving at a crime scene is to assess the situation. Ensure that it is safe to enter the area. Look for any potential dangers, such as ongoing violence or hazards that could affect safety.
- Establish a Perimeter:
- Use crime scene tape or markers to establish a perimeter around the area where the crime occurred. This prevents unauthorized persons from entering and potentially disturbing evidence. Make sure to keep the area large enough to allow investigators to work effectively.
- Control Access:
- Limit access to the crime scene to only authorized personnel. This may include law enforcement officers, investigators, and forensic teams. Keep onlookers, witnesses, and other unauthorized individuals out of the area.
- Preserve Evidence:
- Ensure that any physical evidence (e.g., fingerprints, footprints, blood, weapons) is not touched or altered. Explain to pupils that even small pieces of evidence can be crucial for solving a crime, so they must not disturb anything they see.
- Document the Scene:
- If it is safe and feasible, document the scene with photographs or videos from various angles. This documentation can be vital for investigations and legal proceedings. Teach pupils to take notes about what they observe, including details about the scene and any individuals present.
- Notify Authorities:
- Always contact the appropriate authorities immediately if a crime has been committed. This could include calling the police or notifying a security officer. It’s important to provide them with all relevant information about the scene.
- Stay at the Scene:
- Unless it’s unsafe, stay at the scene until authorities arrive. This allows you to provide important information about what you witnessed and ensures you can guide authorities to key evidence if necessary.
Importance of Securing a Crime Scene
- Preservation of Evidence: Properly securing a crime scene ensures that evidence remains intact for investigation. This is crucial for solving crimes and holding perpetrators accountable.
- Prevention of Contamination: Disturbing a crime scene can lead to contamination of evidence, making it unreliable or unusable in court. Securing the scene prevents accidental damage or loss of critical information.
- Facilitating Investigation: A well-managed crime scene allows law enforcement to conduct a thorough investigation, leading to quicker resolutions and increased safety for the community.
Protecting Witnesses: By controlling access to the crime scene, the safety of witnesses can be maintained, encouraging more individuals to come forward with information.
