Photograph important evidence twice. A medium-distance photograph that shows the evidence and its position to other evidence. A close-up photograph that includes a scale and fills the frame. Acquire prior photographs, blueprints, or maps of the scene. The sketch establishes a permanent record of items, conditions, and distance and size relationships.
Sketches supplement photographs.
Sketch number designations should coordinate with the evidence log number designations. Sketches are normally not drawn to scale. Back to the top Crime Scene Search, Record, and Physical Evidence Collection Use a search pattern such as a grid, strip or lane, or spiral. Search from the general to the specific for evidence. Be alert for all evidence.
