Recent parameters for estimation of time since death: A review study

Estimating the time of human death remains one of the most challenging questions in forensic medicine. Since ancient times, the determination of the time of death has struggled all professional figures involved around corpses because time since death determination can be a remarkably difficult goal to achieve. Time since death is defined as the amount of time that has elapsed between the death of the decedent and the time of the post mortem examination. In this present systematic review paper, we have reviewed some online journals and some of the standard books of forensic medicine and toxicology. All the methods used for the determination of time since death are not totally accurate and they only offer a simple approximation, but due to the development of new scientific fields like molecular biology, has meticulously evaluated the rate of degradation of biological markers (e. g. Proteins DNA, RNA) in order to obtain more accurate time since death.
