Scene Arrival & Setup - First Steps Crucial
- Initial Actions & Safety:
- Safety First: Assess all hazards (biological, chemical, physical).
- Scene Assessment: Determine scope, nature, approx. victims.
- Establish Command Post: Central coordination.
- Scene Security (Cordon Sanitaire):
- Inner Cordon (Hot Zone): Restricted to DVI personnel.
- Outer Cordon (Warm Zone): Staging area, access control.
- Media Cordon: Designated area for media.
- Team & Equipment:
- Team Briefing: Define roles, responsibilities, communication.
- Equipment Check: Verify DVI kits & tools are functional.
📌 S.C.A.N.E. (DVI On-Arrival)
- Secure the scene (cordons)
- Command & Control (establish post)
- Assess hazards & scope
- Notify & Brief team
- Equipment check

⭐ The establishment of a clear command structure (e.g., Incident Command System) is paramount in DVI scene processing.
Search & Recovery Ops - Finding The Fallen
Systematic search locates remains and evidence. Recovery follows strict protocols per BNSS procedures.
Search Patterns:
| Pattern | Description | Pros | Cons |
|---|---|---|---|
| Grid | Area searched twice (perpendicularly) | Thorough; small areas | Time-consuming; needs boundaries |
| Line | Team moves in line across area | Quick; large, open areas | Less thorough |
| Spiral | Circular paths (inward/outward) | Single searcher; specific points | Disorienting; uneven coverage |
| Zone | Area divided into sectors, searched | Manages large/complex; adaptable | Needs coordination; potential overlap |
- In-situ examination: Document position and condition before disturbance per BNSS guidelines.
- Photography: Comprehensive photo-documentation before removal following BSA evidence standards.
- Respectful handling; minimize disturbance to body and surrounding evidence.
- Temporary body numbering/tagging for each body/part found using ICD-11 classification system.
⭐ Fragmented remains require extreme care in recovery and precise location mapping, as they may belong to multiple individuals or a single dismembered victim, following ICD-11 injury classification protocols.
Documentation & Tagging - Every Detail Matters
- Scene Documentation: Meticulous recording.
- Notes: Detailed written observations.
- Sketches: Scene layout, victim/evidence positions.
- Photography & Videography: Overall, mid-range, close-ups; use scale.
- Victim Documentation:
- Assign unique DVI number (e.g., IND/001) to body/parts.
- Body charts: Diagram injuries, features, clothing.
- INTERPOL DVI Forms: Standardized data.
- Pink (AM): Ante-mortem data (family/records).
- Yellow (PM): Post-mortem data (examination).
- Evidence Collection & Handling:
- Personal effects (jewelry, IDs, clothing).
- Trace evidence (fibers, hair).
- 📌 Photograph, Sketch, Collect, Document/Preserve: Comprehensive evidence handling principles for laboratory examination.
- Chain of Custody: Unbroken record for items (scene to lab) per BNSS procedures.

⭐ The INTERPOL DVI forms (Pink for Ante-mortem, Yellow for Post-mortem) are internationally recognized standards for data collection.
Evidence & Transport - Chain of Custody
- Non-Biological Evidence:
- Collect documents, jewelry, personal effects.
- Handle with care; maintain integrity.
- Hazardous Materials:
- Follow safety protocols for handling.
- Temporary Morgue:
- Site: Secure, accessible, adequate space.
- Refrigeration: Essential, aim for 0-4°C (32-39.2°F).
- Security: Restrict access, maintain log.
- Transportation of Remains:
- Vehicles: Appropriate, discreet (e.g., refrigerated trucks).
- Dignity: Ensure respectful handling.
- Chain of Custody Log: Use automated technology for real-time documentation; meticulously document transfer.
⭐ A robust chain of custody must be maintained for all recovered remains and property from the scene to the mortuary to ensure evidentiary integrity under BSA provisions. Any gaps should be avoided and discrepancies researched and reported.
High-Yield Points - ⚡ Biggest Takeaways
- Scene security is paramount, preventing unauthorized access and contamination.
- Use systematic search patterns (grid, line) for thorough evidence recovery.
- Flag, photograph, and document all remains and evidence in situ meticulously.
- Proper labeling of recovered items and strict chain of custody are crucial.
- Follow INTERPOL DVI guidelines for international cases, while adhering to NFSU/BPR&D protocols for domestic disaster victim identification within India.
- A multidisciplinary team approach (police, forensic experts, odontologists) is vital.
- Establish a temporary field mortuary for organized initial processing if needed.
