What does minPMI represent?

• A. The time when the first flies lay eggs on a body.
• B. The time when the last maggot leaves the body.
• C. The time when laboratory analysis is completed.
• D. The time from death to discovery.

Answer: (A)

The main idea is that minPMI is the minimum postmortem interval—the earliest time that could have elapsed since death based on the initial insect evidence on the body. In forensic entomology, the first to arrive are flies that lay eggs on a corpse. Observing that initial egg deposition provides the earliest possible time of death, because colonization marks the start of postmortem insect activity. By knowing how fast those eggs develop under the observed temperature, you can back-calculate to a minimum estimate of when death occurred.

The other options describe later stages or different concepts: the moment maggots finish feeding would come after initial colonization, lab analysis completion is unrelated to when death occurred, and time from death to discovery is the actual PMI, not the minimum estimate.
