How much decomposition has occured when a body has been dead for 4 days in a contained environment like an apartment?

Answer 1

A dead body cannot avoid decomposition when exposed to things like temperature and humidity. Shortly after death, the blood begins to succumb to the effects of gravity and will start to pool. Then rigor mortis sets in and shortly thereafter, the body will begin to bloat. Left in a room-temperature apartment, the human body will enter the stage of active decay.

Answer 2

After 4 days, the body will have typically undergone early stages of decomposition such as bloating, discoloration, and a strong odor due to the release of gases by bacteria. In a contained environment like an apartment, the level of decomposition may be accelerated due to the lack of ventilation and increased temperature, which can speed up the decomposition process.
