Why did body decompose in morgue only after 3 days?

Body decomposition in a morgue may be delayed for several reasons, including the controlled environment of the morgue, which typically maintains cooler temperatures and reduced humidity to slow down bacterial activity. Additionally, the use of embalming fluids can further inhibit decomposition. Factors like the individual's health at the time of death, the presence of any preservatives, and the conditions of the body can also impact the rate of decomposition.
