Step 1: Understand the Different Forms of Crime Scene Documentation

Crime scene documentation can be categorized into three primary forms:

1. Written Notes
   • Serve as a chronological record of observations, including date, time, location, and initial impressions.
   • Include detailed descriptions of the scene, environmental conditions, and the evidence found.
2. Photography
   • Provides a visual record of the scene and evidence before anything is moved.
   • Ensures accurate representation of spatial relationships and evidence placement.
3. Sketching
   • Offers a scaled representation of the crime scene.
   • Complements photographs by depicting spatial relationships, measurements, and evidence positions.
4. Video Recording (Optional but increasingly used)
   • Provides a real-time walkthrough of the crime scene, capturing the overall layout and context.

Step 2: Types of Photographs Needed for Crime Scene Documentation

When documenting a crime scene through photography, include the following:

1. Overview Shots
   • Capture the entire scene and its surroundings.
   • Provide context for evidence placement and spatial relationships.
2. Mid-Range Shots
   • Focus on the evidence within its immediate environment.
   • Show the relationship between specific items of evidence and their surroundings.
3. Close-Up Shots
   • Highlight specific pieces of evidence, including small or intricate details.
   • Take photographs both with and without a measurement scale.
4. Specialized Shots
   • Use techniques like alternate light sources or filters to capture specific details (e.g., bloodstains or latent fingerprints).

Step 3: Understand the Importance of Sketching Crime Scenes

Sketches are vital because they:

• Provide a bird’s-eye view of the scene and evidence placement.
• Include measurements and spatial relationships that photographs might not capture.
• Are admissible in court as an objective representation of the crime scene.

Step 4: Include Key Elements in a Crime Scene Sketch

When creating a sketch, ensure the following elements are included:

1. Title Block
   • Include details such as case number, date, location, and the person creating the sketch.
2. Legend
   • Use symbols to represent evidence and other items in the sketch, with an explanation in the legend.
3. Compass Direction
   • Indicate the orientation of the scene (e.g., North arrow).
4. Scale
   • Provide a clear scale (e.g., 1 inch = 10 feet) to represent distances accurately.
5. Evidence Markers
   • Clearly label evidence items with numbers or letters that correspond to your notes or photographs.
6. Measurements
   • Include accurate measurements between evidence and fixed reference points.

Step 5: Write Your Paper

Now that you’ve broken down the key components:

• Start with an introduction explaining the significance of crime scene documentation.
• Dedicate separate sections to discussing written notes, photography, and sketches.
• Highlight the role of photographs and sketches in court and investigations.
• Conclude by emphasizing how these tools ensure a thorough and reliable investigation.
