Livor mortis (from Latin līvor 'bluish color, bruise' and mortis 'of death'), postmortem lividity (from Latin post mortem 'after death' and lividitas 'black and blueness'), hypostasis (from Greek ὑπό (hypo) 'under, beneath' and στάσις (stasis) 'a standing') [1] [2] or suggillation, is the second stage of death and one of the signs of ...
The stages that follow shortly after death are: Corneal opacity or "clouding". Pallor mortis, paleness which happens in the first 15–120 minutes after death. Livor mortis, or dependent lividity, a settling of the blood in the lower (dependent) portion of the body. Algor mortis, the reduction in body temperature following death.
Rigor mortis: stiffening of limbs. Conditions at the scene of death affect the estimation of time of death. To algor mortis, livor mortis and rigor mortis, together with consideration of stomach contents, there needs to be some observation of environmental conditions at the death scene to accurately measure the PMI (Fig. 1).

Putrefaction is the fifth stage of death, following pallor mortis, livor mortis, algor mortis, and rigor mortis. This process references the breaking down of a body of an animal post-mortem. In broad terms, it can be viewed as the decomposition of proteins, and the eventual breakdown of the cohesiveness between tissues, and the liquefaction of ...
Livor mortis – settling of the blood in the lower (dependent) portion of the body; Algor mortis – reduction in body temperature following death. This is generally a steady decline until matching ambient temperature; Rigor mortis – limbs of the corpse become stiff (Latin rigor) and difficult to move or manipulate
Shortly after death, within three to six hours, the muscular tissues become rigid and incapable of relaxing, during a stage called rigor mortis. Since blood is no longer being pumped through the body, gravity causes it to drain to the dependent portions of the body, creating an overall bluish-purple discoloration termed livor mortis or, more ...
Investigators may use it to determine if a body has been moved or repositioned after death. Livor mortis starts 20 minutes to 3 hours after death and is congealed in the capillaries in 4 to 5 hours. Maximum lividity occurs within 6–12 hours. By far, the most commonly documented transient medical evidence is blood alcohol level.
