Which of the following is an application of determining Post Mortem Interval?

• A. Neglect cases
• B. Entomotoxicology is an application of PMI.
• C. Extracting human DNA from evidence
• D. Assessing body disposal methods.

Answer: (B)

Understanding PMI is about placing the time of death within a useful window for the investigation, and some applications extend beyond a single numerical estimate. Entomotoxicology sits at the intersection of entomology and toxicology in the postmortem context. It involves analyzing toxins found in insects that have fed on the corpse to detect drugs or poisons present in the body and to understand how those substances may have affected insect development. Since the rate of insect growth and the pattern of colonization are time-dependent, studying these toxins in insects helps refine the estimated time since death and can illuminate the likely toxic exposure as part of the death investigation. That connection to timing and cause of death makes entomotoxicology a direct application of determining PMI.

Neglect cases, DNA extraction, and body disposal methods pertain to other aspects of forensics and don’t hinge on estimating or applying PMI in the same way.
