Searching the Scene One of the most effective methods of conducting a search for bomb components and debris is with the grid search pattern. The number in each grid will correspond to the evidence specimen number on the evidence recovery log. Documenting The plotting of a grid search pattern on a diagram provides a visual representation of where specific items of evidence were located before being transferred to inventory. In structure bombings, this grid may extend to the outside of the target room/area and encompass adjoining rooms and even outside of the structure itself. 6 Documenting IED Improvised Explosive Device A report with a detailed narrative is mandatory.
