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 ...
[14] [12] In a clearer contemporary terminology, algor mortis, livor mortis and rigor mortis are called "early postmortem" changes, in distinction from the "immediate postmortem" changes associated with the cessation of bodily functions, as indicated by vital signs. [15] With an ophthalmoscope, changes to the blood in the retina are quickly ...
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).

Pallor mortis – paleness which happens in the 15–120 minutes after death; 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
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.
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 ...
A dead body holds its position as rigor mortis sets in. If the body is moved after death, but before rigor mortis begins, forensic techniques such as livor mortis can be applied. Rigor mortis is known as transient evidence, as the degree to which it affects a body degrades over time.
Some indicators that investigators use are rigor mortis, livor mortis, algor mortis, clouding of the corneas, state of decomposition, presence/absence of purged fluids and level of tissue desiccation. [2] Pathologists can assume a time of death via analysing necrophagous diptera. The odour from decaying flesh attracts different species as the ...
