Crime Scene Search Patterns Flashcards
Searchers must examine all surfaces that come into their swath (view) for evidence
Examples: underside of cabinets; ceilings;table legs; trees; shrubs;etc.
Three dimensional process
Considerations:
nature of the ground being searched, lighting conditions, environmental conditions, size of potential item(s)/ evidence
Selecting a search pattern
Involves selecting a starting point and moving inwards or outwards in a circular pattern. Primarily a single person technique. Useful in most interior or confined exterior scenes
spiral search
Involves multiple searchers following a single strip in one direction, while in-line with the each other
Line Search
Involves a single searcher who follows a single strip across a crime scene, and then turns around and does the same in the opposite direction
Strip Search
Multiple searchers follow strips in one direction across a crime scene, and then repeat with another set of strips oriented at 90 degrees angle to the first. Similar to line search. Provides searchers with multiple views, different perspectives of the same ground
Grid search
Can be used in two different ways. Works in small spaces where no other search patterns work.
Can be used to break up larger scenes into smaller functional areas that can then be searched using a another pattern
Zone Search
