Crime Scene Management: Foundations, Principles, and Procedures

This easy-level mock covers the foundational vocabulary, principles, search patterns, measurement methods, and evidence collection and documentation protocols of crime scene management. All thirty questions are pitched at the definitional level — the baseline knowledge every NFSU MSc, FACT, and UGC-NET candidate must master before approaching application-level material.

Questions cover the primary vs secondary crime scene distinction (where the crime happened vs related locations), Locard's Exchange Principle (every contact leaves a trace; two-way transfer), the three-tier photography sequence (overview → mid-range → close-up), chain of custody definition and purpose (continuity documentation; gap creates doubt), PPE dual function (protect investigator AND protect scene from investigator), First Responding Officer role (SAFE: Safety, Aid, Freeze, Evidence-note), the grid search pattern (double strip; most thorough), the scene attendance log (every person who enters; name + role + time), the initial walk-through (plan and assess without disturbing; not a collection exercise), the strip/line search pattern (large open outdoor areas), trace evidence definition (fibres, hair, glass, paint, soil, pollen; small transferred materials), reference/control samples (establish background baseline for comparison), the spiral search pattern (single focal point; one or two searchers), the baseline measurement method (reference line + two measurements per item), the rectangular coordinate method (two perpendicular walls; x and y coordinates), fire death scene examination order (safety → document → origin → samples → body last), evidence markers (numbered placards placed before photography), triangulation method (distance from two fixed reference points), PPE for biological scenes (gloves + coverall + overshoes + mask), the zone/quadrant search pattern (large complex indoor/outdoor scenes), wet blood collection (swab + air dry + paper packaging; never airtight plastic), the polar coordinate method (fixed point + reference bearing + distance + angle), close-up photography requirements (with and without scale; before collection), sketch vs photography (sketch records measurements; photographs record appearance), footwear impression collection (photograph + dental stone casting), perimeter establishment (large initially; easier to shrink), documentation sequence (notes → photography → sketching → collection; never collect first), evidence packaging (paper for biological; sealed for non-biological), secondary crime scene definition (related to crime; not where crime occurred), and initial walk-through purpose (assess and plan without collecting).

Topics covered:

• Principles: Locard's Exchange Principle; primary vs secondary scene; chain of custody
• Personnel: FRO role (SAFE); CSI role; PPE dual purpose
• Search patterns: grid (most thorough), strip (open outdoor), spiral (focal point), zone (complex large), and when each is used
• Documentation: three-tier photography, close-up with/without scale, scene sketch vs photography, documentation sequence, evidence markers, attendance log
• Measurement methods: baseline, rectangular coordinate, triangulation, polar coordinate
• Evidence handling: trace evidence types, reference samples, wet blood packaging, footwear impression casting, perimeter establishment

Each question carries a detailed explanation citing Saferstein's Criminalistics and NCRB/BPR&D crime scene investigation guidelines. Allow 30 minutes.
