What is the recommended sequence for documenting a crime scene from arrival to evidence collection?

• A. Document entry/exit after all evidence is collected.
• B. Stop the incident and secure the area; preserve life; limit access; document entry/exit; photograph/video; collect and package evidence; label and seal; maintain chain of custody.
• C. Take photos first; then leave.
• D. Destroy the evidence to prevent further contamination.

Answer: (B)

The sequence tested centers on protecting people and preserving the integrity of the scene from the moment you arrive. The first priority is to stop any ongoing incident, secure the area, and preserve life if needed, while restricting access to prevent contamination. This creates a stable, controlled environment so nothing is disturbed unnecessarily.

Next, you document who enters and leaves the scene and when. This establishes an official record of access and activities, which is crucial for reconstructing events later and for accountability.

After securing and documenting, you capture the scene with photographs or video. Creating an accurate visual record before touching or moving items helps preserve the original state and supports later analysis and court proceedings.

Only then do you begin collecting evidence, using proper methods to package each item. Careful packaging prevents cross-contamination and preserves the item’s condition, while labeling and sealing clearly identifies the item and its source.

Maintaining the chain of custody throughout ensures a documented, auditable trail of every person who handled the evidence, when, and where it was stored. This combination of protection, documentation, documentation of access, comprehensive recording, careful collection, and chain-of-custody is what keeps the evidence reliable and admissible.

Options that skip or reverse these steps fail to preserve the scene’s integrity or the evidentiary trail: documenting entry/exit after collection undermines accountability; taking photos and then leaving prematurely allows changes to occur; and destroying evidence is illegal and defeats the entire purpose of scene processing.
