Which factors can influence the estimation of time of death?

The estimation of the time of death is a complex process that involves analyzing various physical changes that occur post-mortem. Livor mortis, rigor mortis, and algor mortis are critical physiological changes that provide forensic experts with valuable information regarding the time elapsed since death.

Livor mortis, or post-mortem lividity, refers to the settling of blood in the lowest parts of the body due to gravity. It typically begins within 20 minutes to a few hours after death and can help determine whether a body has been moved post-mortem based on the distribution of these purplish discolorations.

Rigor mortis is the stiffening of muscles that occurs after death, usually starting within a few hours and becoming fully developed within 12 to 24 hours. This process can provide clues about the time of death based on the degree of stiffness observed in the body.

Algor mortis describes the cooling of the body after death, influenced by factors such as the ambient temperature and the deceased's body composition. This cooling rate can provide a time estimate in the absence of other indicators.

These three post-mortem phenomena are interrelated and can help forensic pathologists establish a timeframe for death with greater accuracy than any single external
