However, there may be circumstances that may suggest a sketch be created.Sketches are not to be substituted for photographs, reports, or field notes. Remember from ourdiscussion on notes; notes, photographs, and sketches are to support and complement each other.5.3 CATEGORIES OF SKETCHESThere are two categories of sketches:1.Rough2.2. Final5.3.1 ROUGH SKETCHA rough sketch is completed at the scene. It should be created in pencil. A pencil is the idealinstrument because of all the editing that is necessary during the creation of the sketch. Using apen makes it difficult to correct minor mistakes. The more you edit the rough sketch with a pen,the messier the rough sketch becomes. Eventually, this may result in pertinent measurementand/or other details of the sketch being altered or lost. The rough sketch can be created severalways. It may be done free handed or by the use of commercially available crime scene templates.The paper used may be a large tablet of drawing paper or graph paper. Notebook paper willsuffice if that is all you are able to obtain each sketch, a header, legend, scales and orientationindicators.Rough sketches should include pertinent measurements of the scene and items within the scenesuch as furniture, cabinets, shelves, and fixtures as well as evidence. The walls, doors, andwindows should all be documented and measurements obtained. The sketch should also includeimportant measurements for proper analysis of bloodstains and shooting scenes. If the finalsketch is intended to be viewed in 3D, height measurements become extremely important.Rough sketches can become very detailed very quickly. One method to alleviate this is to createseparate sketches for each room or wall containing bullet defects and/or bloodstain patterns. Nomatter how many sketches are created within a scene, the following information should appearon each sketch.5.3.2Final SKETCH
The final sketch must be completed in ink. The final sketch may also be computer generatedsince most crime scene investigators are not architects or licensed surveyors, and thus, the finalsketch will not be an architectural drawing. Thus, the courts only require that the final sketch bea true and correct representation of the scene and not a scaled architectural drawing.5.4 SKETCH VERSUS FORENSIC MAPA sketch only depicts the scene in an only visual reference. That is, measurements cannot bemade directly from a sketch. A sketch may include dimension lines to show room size. A sketchwill lack a reference scale that is used to obtain measurements directly from the sketch. Aforensic map on the other hand includes a scale (e.g., 1″ = 10′) that may be used to obtainapproximate measurements directly from the forensic map. Please understand this does not makethe forensic map an architectural drawing simply by including the scale.
