Crime Scene Preservation and Search: Foundations (UGC-NET Unit I)

UGC-NET Forensic Science Unit I drill on crime-scene preservation and search methods, covering the nature and types of scenes (primary/secondary, indoor/outdoor, macroscopic/microscopic, expanding/contracting), perimeter control and access logs, the initial walk-through, the four search patterns (spiral, strip, grid, zone) and their suitability, scene photography and sketching, time-critical degradable evidence, weather and lighting handling, and Indian first-responder SOPs from the Bureau of Police Research and Development and the Central Forensic Science Laboratory. Easy-band questions calibrated for first-pass UGC-NET preparation and quick concept refresh.

For UGC-NET Paper II aspirants, NFSU MSc entrants, and FACT candidates working through the crime scene management module. Questions emphasise definitions, sequence of action, and the Indian procedural framework under BNSS 2023 and BSA 2023, including the role of the panch witness and the scene mahazar.

Topics covered:

• Nature and types of scenes (primary, secondary, indoor, outdoor, expanding)
• Securing the perimeter, inner and outer cordon, access logs
• Initial walk-through and first-responder priorities
• Spiral, strip, grid, and zone search patterns and when each fits
• Crime-scene photography (overall, mid-range, close-up) and scale use
• Rough sketch, finished sketch, and contemporaneous notes
• Time-critical degradable evidence, weather and lighting handling
• BPRD and CFSL SOPs, chain-of-custody triggers at scene transfer

Useful for revision and self-testing before the UGC-NET Paper II Unit I examination.
