Question

What is liver mortis? How might this reveal information about the time of death?

Answer 1

Liver mortise is a sign of death and discolored skin shows that you are about to die
So doctors then perform autopsies on the human of the lower body

Answer 2

Livor Mortis i think you meant is the 4th stage of death
( one of the signs of death ).
It is the settling of the blood on the lower part of the body
Causing a purplish red discoloring of the skin

When the heart stops functioning and is no longer agitating
(transferring/moving) the blood,
Heavy red blood cells sink through the serum ( cell free fraction of blood )
by action of gravity.

[ in this case, the blood travels faster in warmer conditions and slower in cold ]
