Document Summary
Recognition: considerations of what could be evidence. Spatial relationships also important: recognition of not just what but where, situation of items in relation to each other, bones, weapons and victims. Searching a scene is a damaging event: ensure photos obtained before search process, as potential evidence found. Location marked & photos taken: how to search, consider paths of contamination, perpetrator activity, emergency response. How to search: most important to be methodical and systematic, method used based on variety of factors, outdoors/indoors, outdoors: terrain, weather, size, urgency, lighting available, what being searched for, evidence already found, concentration of material, people available. Searcher goes back and forth across scene, with slight overlap: like mowing the lawn, often done in outdoor scenes, e. g. For increases detection ability: after searching in one direction, searcher goes over same area at 90 angle to previous direction. Line search: used in large/outdoor scenes, requires several searchers, assemble in a line along edge of the scene.
