What is pmi in forensics?

PMI (Post Mortem Interval) in forensic science refers to the estimation of the time that has elapsed since an individual's death. Determining the PMI is vital in investigations involving suspicious deaths or forensic cases where the timeframe of the incident is crucial for establishing the sequence of events.

Forensic scientists use various methods and techniques to estimate the PMI, such as assessing the level of rigor mortis, body temperature, livor mortis (discoloration of the skin), and decomposition of the body. Additionally, entomological evidence, such as the presence of insects on the body, can also provide valuable information in estimating the PMI.

Factors such as the environmental conditions, the individual's health status, and the presence of any drugs or toxins in the body can also affect the accuracy of PMI estimation. Despite the challenges and limitations in determining the exact time of death, forensic scientists aim to provide the most accurate estimate possible to aid in criminal investigations and legal proceedings.
