Detailed explanation-1: -This period runs from 3 to 72 hours after death. The early post-mortem phase is most frequently estimated using the classical triad of post-mortem changes – rigor mortis, livor mortis, and algor mortis.

Detailed explanation-2: -Postmortem interval (PMI) is the time that has passed since the death of a person until found, is an essential tool in forensic investigations as providing an estimated time since death, is pivotal in judicial cases and can even either incriminate or acquit a suspect.

Detailed explanation-3: -Forensic entomology is now an integral part of a death investigation when estimating the time since death beyond 72 h. Forensic entomology is considered the most accurate method for estimating the elapsed time since death, particularly when more than 3 days have elapsed.

Detailed explanation-4: -A considerable amount of work has been carried out by scientists to accurately determine time since death. Algor mortis, rigor mortis, supravital reactions, and post-mortem decomposition have been a routine tool for the estimation of post-mortem interval for many years.
