Problems in Estimating the Postmortem Interval in Death Investigations
نویسنده
چکیده
Estimation of the postmortem interval (PMl) using faunal diversity, development and succession in human death investigations is based on a number of assumptions. Investigators should not be overly dependent on the few baseline studies currenlly in use to estimate the PM!. This paper reviews a number of problems to be considered when using inse<:ts to estimate the PMI: 1. Insect activity in inclement weather and at night. 2.1'iming of blow fly oviposition. 3. Mixed fly populations and staggered broods. 4. Seasonal efTects on maggot-generated heat. 5. Effect of maggot-generated heat. 6. Impact of species arriving out of sequence. 7. Availability of gravid blow ny recruits at the scene. 8. Effect of drugs, toxins, and parasitoids on maggot development. A discussion of these problems is presented along with some approaches to their solution.
