2. Target 1-2
I can document a crime scene by identifying, labeling, and sketching evidence.

3. Crime Scenes Primary Crime Scene Secondary Crime Scene
Where the actual crime took place
Ex) a mugging took place on a sidewalk
Secondary Crime Scene
A location other than the primary crime scene, where important evidence is located
Ex) a suspect’s home or car
Ex) a location where a body was dumped

4. Documenting a Crime Scene
Scan and isolate the scene
The “scene” must contain all the evidence
Keep the scene safe from outside influences (people, weather, vehicles, etc.)
Photograph the scene and all evidence
Keep evidence in its original location
Use rulers in photos to record size and shape
Take notes and measurements (rough sketch)
Draw a scaled crime scene diagram

5. Crime Scene Diagrams Must be drawn to scale Must show: Must have a key
Doors, egress windows
Large furniture/obstacles
Evidence
Victim(s)
Must have a key
Must record date, time, and artist

6. Labeling Objects All objects and evidence must be labeled and keyed
Use rectangles and circles to show locations of obstacles (furniture and large objects)
Use letters to label obstacles AND to show locations of evidence
Use the same letter and add numbers for multiple objects
Ex) multiple blood drops could be A1, A2, A3, etc
