Estimation of Postmortem Interval (PI) or Time since Death (TSD) is an important objective of post-mortem examination which connects an accused to the particular moment of time to prove his guilt or innocence. This plays an essential role in investigation of medico legal cases. In India, the PI/TSD is estimated on the basis of naked eye changes after death and it is always mentioned in every post-mortem report done by the Forensic Pathologist. This estimation is always a challenge for Forensic pathologists due to various variable factors. The authors present a case of a person who died in unknown time duration and the external changes observed were differential in different parts of the body, a phenomenon rarely cited in standard literature. The authors recommend intensive studies to be initiated in Indian settings to determine a scientific data for the actual time taken for the process of decomposition.
