what do you call the outline of a dead body
Chalk outline Classically, white or bright yellow chalk is used, although some may use paint or white tape. 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.[1]
Rigor mortis Rigor mortis (Latin: rigor "stiffness", mortis "of death"), the third stage of death, is one of the recognizable signs of death, caused by chemical changes in the muscles post mortem, which cause the limbs of the corpse to stiffen.[1] In humans, rigor mortis can occur as soon as 4 hours post mortem.[1]
