How to estimate PMI

  1. Collect immature blow flies from corpse

  2. Hold blow flies in the lab at constant temperatures until they reach the adult stage

  3. Determine ADH from field-collection to emergence in the lab

  4. Review published literature for development requirements of the emerged species

  5. Determined ADH experienced on the corpse

    1. Calculate field ADH
