What is the difference between rigor mortis and putrefaction?
Immediately after death, the muscles undergo primary relaxation, as mentioned above, which is followed by stiffening of muscles known as rigor mortis. With the onset of putrefaction, rigor mortis passes off, and secondary relaxation occurs. Rigor mortis is the post mortem stiffening/ rigidity of the body.
Can dead bodies scream?
However, while corpses aren’t likely to scream or yell, they are likely to make noises such as moans, groans, hisses, and grunts. Another way these noises can occur is when the gases in the body begin to build up. They can escape through the windpipe, causing squeaks, hisses, and sometimes lower groaning.

Why do bodies get hard after death?
The cells no longer have the energy to pump calcium out of the cell and so the calcium concentration rises, forcing the muscles to remain in a contracted state. This state of muscle stiffening is known as rigor mortis and it remains until the muscle proteins start to decompose.
