Integrated Scene Documentation Exercise — Full Simulation

What This Exercise Is — and Why It Matters

Every skill you have practiced in isolation — camera settings, sketching, measurement, narrative writing — now works together in a single, timed simulation. Real scenes do not wait for you to feel ready. Dispatch sends you to an address, a clock starts, and every decision you make (or skip) becomes part of the permanent record. This exercise replicates that pressure so that your habits are solid before you face a real scene.

A complete documentation package has three inseparable parts: photographs, a scale diagram, and written notes. A prosecutor, defense attorney, or cold-case investigator who was never at the scene must be able to reconstruct it entirely from your package. If any part is missing or inconsistent with the others, your credibility — and the case — suffers.

Before You Enter: The Pre-Scene Checklist

Professional documentation begins at the curb, not at the first evidence marker. Before crossing any threshold, complete your pre-scene checklist:

• PPE donned and inspected — gloves, shoe covers, and eye protection minimum; add respiratory protection if the scene calls for it. Never enter a scene without gloves; contact with evidence or surfaces can transfer your DNA and destroy latent prints.
• Equipment function-checked — camera battery charged, memory card formatted and empty, tape measure extended and retracted to confirm it locks, laser measurer battery confirmed, scale cards in pocket, sketch forms on clipboard.
• Dispatch sheet reviewed — note scene type, address, reported evidence, and responding personnel so your narrative header is accurate from the first line.
• Walk-around observation — one complete circuit outside before interior entry; note entry/exit points, weather, lighting, and any hazards such as broken glass, biohazard material, or unstable structures.

Do not touch, move, or photograph any item until the walk-around is complete. Premature handling destroys context.

The Documentation Sequence

Follow this sequence every time, without exception:

1. Overview photographs — establish the entire scene from each cardinal direction and from any elevated vantage point available. These frames prove what the scene looked like before anything was disturbed.

2. Mid-range photographs — each evidence item photographed in relationship to a fixed landmark (door frame, wall corner, permanent fixture). A viewer must understand where in the scene the item sits.

3. Close-up photographs — each evidence item filled in the frame, first without a scale, then with an ABFO No. 2 scale or ruler placed parallel to the item. Both frames are required; the scale frame is used for measurement, the no-scale frame shows natural appearance.

4. Field notes and narrative — written in the present tense as you observe, recording time, lighting conditions, weather (for outdoor areas), item descriptions, and your own movements through the scene.

5. Rough sketch with measurements — hand-drawn on your sketch form, not to scale, but with all measurements recorded using the baseline, triangulation, or rectangular coordinate method as appropriate to the scene geometry. Include a north arrow and compass direction on every sketch page.

6. Photo log — completed in the field as you shoot; each frame numbered with subject, direction of view, and any special conditions noted.

Returning to the Lab: Finished Diagram and Photo Log

Your rough sketch becomes a finished, to-scale diagram using drafting software or graph paper. Every measurement from the field must transfer exactly — do not estimate or adjust. The finished diagram must include: title block (scene address, date, your name, diagram number), north arrow, scale bar or stated representative fraction, all walls or boundary lines, all eight evidence items labeled to match your photo log and notes, and a legend.

Your photo log is printed and organized to match frame numbers on your camera. Each entry must match what appears in the corresponding image. Inconsistency between the log and the image — a scale listed as present when it is absent in the frame — is a critical error.

Critical Omissions and Why They Fail Cases

Three errors are treated as critical in this course because courts and peer reviewers treat them the same way in practice:

• No north arrow on sketch or diagram — orientation is lost; measurements cannot be re-established during re-investigation.
• No scale in close-up photographs — size cannot be determined from the image; the photograph cannot be used for measurement comparison.
• Evidence item missing from both notes and diagram simultaneously — the item effectively does not exist in the documented record.

Any single critical omission requires a repeat simulation. A missing scale in one photograph is correctable with documentation; an item missing from every record is not.

Safety at the Simulated Scene

Even in a simulation, treat PPE as mandatory. Staged scenes may contain prop blood or biological-appearing substances, broken prop materials with sharp edges, or tight spaces with trip hazards. Gloves are worn from entry to exit. If you find an item that was not pre-briefed as a prop — a real sharp, an unknown liquid — stop, back out, and notify your instructor immediately. Lockout procedures for hazardous areas follow the same principle: if you cannot confirm it is safe, do not enter.

Debrief: Defending Your Decisions

The ten-minute debrief is not a formality. Investigators regularly testify about their documentation choices. Be prepared to explain why you photographed from a particular angle, how you obtained a specific measurement, and why you noted certain observations in your narrative. Clear, confident answers demonstrate that your work was deliberate, not accidental.
