What 4 factors must be taken into account when determining the time of death?

When determining the time of death, four key factors to consider are: the body temperature (algor mortis), which indicates how long it has been since death; rigor mortis, the stiffness of the muscles that progresses over time; livor mortis, the pooling of blood that occurs after death; and the condition of the environment, such as temperature and humidity, which can influence the decomposition rate. Additionally, any signs of injury or trauma may also provide context for estimating the time of death.
