Conclusions Myskowiak and Doums’ (2003) finding that refrigeration of P. terraenovae can affect the development and biometry of larval specimens after only one day of refrigeration suggests that a common forensic practice could be introducing significant error in to PMI estimations. Furthermore, the different relationships between duration of refrigeration, the stage refrigerated, and the time to development indicate that only L3 larvae return to their standard development rate after…

To begin, this discussion is based off the research paper written by Craig Bennell that studies the importance and utility of offender profiling. Some researchers have argued that profiles are often so ambiguous that they can fit a large number of suspects. This decreases its usefulness as a prioritization tool. It is also possible that investigators may also creatively reinterpret the statements the statements of offender profiles in order to make them fit a number of different suspects.…
