link method

seeks to find evidence association in a logical fashion. It works well with small or large, indoor or outdoor scenes.

Line (Strip) Method

Used on large, outdoor crime scenes. Members of the search team are arranged at regular intervals, usually arm's length, and then proceed to search along straight lines.

Grid Method

Used on large, outdoor crime scenes. Searchers follow the first line pattern and search in the same manner as the line method. Once the first line pattern is complete, searchers realign on the other line pattern.

Zone Method

Used on crime scenes that are comprised of readily definable zones, such as in houses or buildings. Teams are assigned small zones for searching, and then other appropriate searching methods are employed in each zone. Scene can be large or small

Spiral Method (Inward or Outward)

Used on crime scenes with no physical barriers, such as with open water, etc. Can either begin at critical point of crime scene (outward spiral) or the outer-edge of the crime scene (inward spiral).

Wheel or Ray Method

Used on small, circular crime scenes. Investigators start from a critical point and travel outward along many straight lines from this point.
