What are five post-mortem indications a pathologist uses to estimate the time of death?

Here are five indications a pathologist uses to find out the time of death in post-mortem:

1. Rigor mortis: The stiffening of muscles after death, which progresses and then resolves over time.
2. Algor mortis: The cooling of the body to ambient temperature. The rate of cooling can help estimate the time since death.
3. Livor mortis: The purplish-red discoloration of the skin caused by the settling of blood in capillaries due to gravity. Its presence, extent, and fixity indicate time.
4. Decomposition: The breakdown of body tissues by autolysis and bacterial action, leading to changes like putrefaction and gas formation.
5. Stomach contents: The amount and state of digestion of food in the stomach and intestines can provide clues about the last meal and thus the time of death.
