Starting with Pre-search photographs, and a preliminary survey to determine the objectives. Planning is the key to a successful search. Starting with photographs and lifts (finger and shoe prints), contents of trash, drawers, phone books, magazines, all may yield clues. Next we see an outdoor crime scene, possible hit and run. Starting with the layout of the search pattern, and the initial Scene sketch, looking carefully for glass, tire marks, paint chips, displaced dirt clods, etc. The search proceeds side by side until evidence is found, detailed and bagged, then the search continues. Measurements taken and verified, tire tracks photographed, and taken with plaster, as are shoe prints.
