Background: The arrival and activity of family Calliphoridae on a deceased corpse indoors can aid in the quantitative measure of the Postmortem Interval. Family Calliphoridae is a group of necrophagous insects that have a proclivity for decomposing corpses and are found worldwide. Their prevalence and activity on a deceased corpse indoors makes it an integral component of estimating the postmortem interval.
Methods: A literary review was performed to support the hypothesis. Case control and retrospective studies were used. Study populations were not restricted to age, sex, or geographical locations. Human studies as well as animal models, due to ethical restrictions, were examined.
Results: Results showed that by paralleling known developmental timelines to Calliphoridae collected from a corpse, investigating pre-arrival interval, understanding external pressures on development, and considering postfeeding behavior can lead to PMI estimated with a higher degree of accuracy.
Conclusion: To disregard the role of Calliphoridae in human decomposition is to renounce a more accurate way of estimating the postmortem interval. More studies should be performed on a variety of Calliphoridae species, pupation in human corpses, and environmental stress on blowfly development to further reduce error in calculating PMI.
