Following photography, a hand-drawn sketch or laser-generated diagram is produced. Unlike photographs, sketches can highlight distances and spatial relationships between objects. A rough sketch is created on-site, noting the compass orientation, key measurements, and the location of each piece of evidence with a unique label. For example, a bloodstain near a window might be labeled ‘B-1’. The final, scaled diagram is later drafted for court presentation. Concurrently, a detailed evidence log is initiated, documenting every item collected, its exact location, the time of collection, and the name of the collector—the genesis of the ‘chain of custody’. Sometimes hair, skin cells, etc
To avoid contaminating the scene with their own hair, skin cells, or fibres, the SOCO wears a full protective body suit, including gloves, a mask, and plastic overshoes. They create a permanent record of the scene using detailed notes, sketches, photographs, and videos. It is critical to document the original position of every item, especially as biological or chemical evidence can deteriorate quickly or be destroyed during recovery.

This is a critical, low-stress assessment where the investigator identifies potential hazards, notes transient evidence (such as odors, temperature, or dew on a body), and determines the most logical entry and exit path. Only after this preliminary survey does the systematic documentation begin. Photography takes precedence over sketching and note-taking because cameras capture the scene’s unaltered condition. Photographs must include medium-range shots that show evidence in context and close-ups that reveal individual details, always with a scale for reference.
