A chalk outline is a temporary outline, usually of a person, drawn on the ground, usually outlining evidence at a crime scene. The outline provides context for photographs of the crime scene, and assists investigators in preserving the evidence. Modern investigators almost never use chalk or tape as outlines at a crime scene to avoid contaminating the evidence. Although rare in modern investigations, they have become a literary trope in popular culture.

Form

Classically, chalk outlines are drawn in white or bright yellow chalk, but paint or white tape may also be used. In the case of a body, a chalk outline might be drawn immediately before the body is to be removed, but after the medical examiner has examined the body.John J. Miletich, Homicide Investigation: An Introduction, Scarecrow Press, 2003, 081084625X, pp. 84–85.

Chalk outlines in practice were typically rough shapes of the body's position and did not include specific arms and leg orientation.See, e.g., Life, "'Clean-up Week' on Docks", May 18, 1953, p. 40. Image at [https://books.google.com/books?id=l0YEAAAAMBAJ&pg=PA40].

History and modern use

While chalk outlines were occasionally used in the past, they were often drawn by the police for press photographers, as opposed to investigative purposes. This allowed the press to take a picture and represent the scene accurately without graphically depicting a body.{{cn|date=December 2024}}

Some sources indicate that, while not part of official procedure, some uninformed investigators may occasionally draw chalk outlines, particularly in non-homicide accidents.{{cite web|author=Cecil Adams |url=http://www.straightdope.com/columns/read/2300/do-crime-scene-investigators-really-draw-a-chalk-line-around-the-body |title=Do crime scene investigators really draw a chalk line around the body? |publisher=The Straight Dope |date=2001-04-13 |accessdate=2013-04-29}} The term "chalk fairy" is occasionally used to describe an officer that makes the chalk outline, often without authorization and while unwittingly contaminating the scene.

While the use of chalk is uncommon, investigators may make smaller marks, or use removable flags, index cards, or markers, to indicate important positions, particularly if other references are not available.{{cite web|archive-url=https://web.archive.org/web/20131109113147/http://forensics4fiction.com/2011/08/24/do-csis-really-use-chalk-outlines/|archive-date=2013-11-09|url-status=dead|url=http://forensics4fiction.com/2011/08/24/do-csis-really-use-chalk-outlines/ |title=Do CSIs Really Use Chalk Outlines? |publisher=forensics4fiction |date=2011-08-24 |accessdate=2013-04-29}}
