Crime scene sketching and diagramming (Forensic Science)
Crime scenes are often very cluttered, jumbled, and confusing. crime scene photographs can contain vast amounts of visual information, much of which may not relate to the particular incident being investigated. By making a sketch or diagram, a crime scene examiner can create a document that visually highlights only those aspects of the scene that are considered to be relevant to the crime.

An annotated sketch or diagram, with appropriate measurements marked, can provide a format for focusing the attention on one aspect, or a small number of aspects, of the crime scene that may be particularly relevant. For example, a single sketch of a light switch showing the general appearance and location of a bloodstain and indicating where a sample of the stain was taken from provides a clear, easily understood visual representation of one aspect of the scene examination. Another, more typical, example would be a sketch of the floor plan of a room indicating the location of a body relative to items of furniture and other significant objects, such as the murder weapon.
