  Livor mortis - Wikipedia, the free encyclopedia
Livor mortis or postmortem lividity, one of the signs of death, is a settling of the blood in the lower (dependent) portion of the body, causing a purplish red discoloration of the skin: when the heart is no longer agitating the blood, heavy red blood cells sink through the serum by action of gravity.
This discoloration does not occur in the areas of the body that are in contact with the ground or another object, as the capillaries are compressed.
Livor mortis starts 1/2 to 3 hours after death and is congealed in the capillaries in 4 to 5 hours.

Depending on the presence and state of livor during the external exam, it may be useful for establishing two key elements of the investigation—postmortem interval and whether or not the body has been moved recently.
A person with anterior livor of just a few hours may have posterior livor by the time they spend the night on a morgue tray as their livor is still fluid and still affected by gravity.
Livor mortis refers to the presentation of blood as it has settled in the body.

Abstract: The aim of this retrospective survey of unintentional carbon monoxide-related deaths in Vienna was to determine whether the cherry-pink coloring of livor mortis is a reliable finding for the coroner to suspect a carbon monoxide-related death immediately at the death scene.
In 98.4% of unintentional carbon monoxide-related deaths livor mortis were clearly cherry-pink.
The percentage of unrecognized carbon monoxide fatalities with a clear cherry-pink coloring of livor mortis almost doubled from 1984 to 1993.

 Investigative Techniques To Determine Time Of Death
Algor mortis, which means "the temperature of death" describes the cooling of the body.
Livor mortis, which means literally "the color of death" is the discoloration of the skin caused by flow of blood into the venous spaces under the influence of gravity.
Livor is not considered to be a good indicator of postmortem interval, but there are some standards which can be seen.

Algor mortis refers to change in body temperature after the heart stops pumping and cellular oxidation, which keeps our body temperatures at 98.6¡ F, stops; the body temperature falls to room temperature (about 70¡ F) at about 1.5¡ F per hour.
Livor mortis refers to the maroon color that develops after the heart stops and no longer churns the blood; heavier red blood cells settle downward from the serum by gravity as occurs in the plastic container when giving blood.
Rigor mortis refers to the hardening of muscle cells that begins shortly after death and causes board-like stiffness in about 12 hours, lasts about 12 hours and then disappears in about 12 hours.

Rigor mortis is a well known phenomenon, and is due to a complex chemical reaction in the body.
As rigor mortis is due to a chemical reaction, the reaction time is due to temperature and the initial concentrations of lactic acid.
Rigor mortis should never be the only basis for estimating time of death.

To examine the possibility of whether the presence of basic drugs in adipose tissue is the result of postmortem change, we examined: tissues with and without livor mortis, concentration gradients within the adipose layer, and the stability of drug concentrations during the postmortem period.
Adipose tissues with and without livor mortis from the thigh area of the same decedent were analyzed for cocaine.
The cocaine concentration of the tissue exhibiting 4+ livor was equivalent to the concentration observed in tissue without livor.

Livor mortis becomes 'fixed' when shifting or drainage of blood no longer occurs, or when blood leaks out of the vessels into the surrounding soft tissue due to hemolysis and breakdown of the vessels.
Thus, the statement that livor mortis becomes fixed at 8-12 h is really just a vague generalization.
That livor mortis is not fixed can be demonstrated by applying pressure to a dependent discolored area and noting the subsequent blanching at the point of pressure." -- DiMaio, Vincent J., DiMaio, Dominick.

 Livor Mortis
The French developed the concept of lividity, or livor mortis, from the French liviere, "to turn blue." This is the gradual deoxygenation and gravitational settling of the blood that begins as soon as lungs and heart cease their motions.
The pink color of early livor gradually darkens to a dull, bruiselike red before progressing through shades of purple and blue as oxygen gradually disappears from the blood.
Oftentimes, the detail can reveal the very texture of the surface on which the victim expired -- be it the stippled inscription of a gritty path, the weave of a carpet, or the design of kitchen linoleum.

Somatic death is followed by a number of irreversible changes that are of legal importance, especially in estimating the time of death.
These include rigor mortis, livor mortis (discoloration of the body due to settling of blood), algor mortis (cooling of the body), autolysis (breakdown of tissue by enzymes liberated by that tissue after death), and putrefaction (invasion of the body by organisms from the gastrointestinal tract).

 Rigor mortis
Rigor mortis is a recognizable sign of human death that is caused by a chemical change in the muscles, causing the limbs of the corpse to become stiff ("rigor") and impossible to move or manipulate.
The biochemical cause of rigor mortis is hydrolysis of ATP in the muscle tissue, the chemical energy source required for movement.
Myosin molecules devoid of ATP become permanently adherent to actin filaments and muscles become rigid.
