This is a 3D Computer Assisted Design (CAD) image.

1. What does it show?

2. What its significance in crime scene investigation?

3. Are their limitations and assumptions of what this shows?

Our Geek of the Week answered:

This appears to show livor mortis, the settling and pooling of the blood after cardiac activity ceases.  In crime scene investigation, it is used to determine if the body has been moved after death, and is one of the factors used to determine the time interval since death. A photo or simulation cannot show whether it is fixed, and would be difficult to show the complexity of the actual patterns. This one doesn’t show the blanching at pressure points / resting places where the blood could not pool due to compression of the tissues. It also doesn’t show the position of the body when found, which may or may not be consistent with the pattern of livor mortis, which may suggest the body was moved after death.

[BLOGGER’S NOTE: Here is our Honorable Mention: Just to amplify an otherwise acceptable answer….

Livor mortis
Livor mortis

The onset of livor mortis (aka lividity) is environment dependent. The major factor that determines its onset is temperature and to a degree humidity. It is characterized as postmortem hypostasis purple coloration in dependent (compressed) areas of the body due to lack of blood circulation. It is caused by accumulation of blood in vessels in dependent areas due to gravity. At a point it becomes fixed due to hemolysis (red blood cell burstis) and collapse of the blood cells themselves. It has also been shown to occur pre-death in torture situations where death is slow or prolonged. In very noticable circumstances petechiae hemorrhage (purple spots on skin) can occur when capillaries and smaller blood vessels collapse or burst. To the uninitiated, its appearance may be misinterpreted as bruising. However, it is thought to be distinguished from bruising as applying pressure to bruise does not cause blanching (loss of color) while unfixed livor mortis does. During an autopsy, an incision into a bruise shows diffuse hemorrhage into tissue, but livor mortis is confined to vessels.

Shown above is fixed livor mortis with petechiae hemorrhages. Also in this picture we can see how dependent areas resting against a firm surface will be pale due to compression of blood vessels.]
