Once the heart stops beating, whether due to homicide or natural causes, the body enters the first stage of death.
Blood drains from the capillaries to the larger veins in the parts of the body, closest to the ground. This process is called livor mortis (embalmers call it “postmortem stain”).
The overall skin, once pink and full of color due to oxygen-laden blood, is now pallid, except for deep purplish-red bands where the corpse touches the ground.
