The bodies discovered in the cabin crime scene were unrecognizably decomposing and had large maggot masses on them.
Students will learn how forensic entomologists use maggots to determine
the post mortem interval (PMI). Students will then examine exemplars
of the life stages of two fly species and develop their own personal key
for distinguishing between life stage and species.
Afterwards, students will use their key to identify a number of
insects that were collected from the corpses. They will then record
that information for the entire class to use. Finally, by comparing
the identification data to a life stage/species development chart and
using National Weather Service data, students will determine the post
mortem interval for both decedents.
This is also a permanent kit, in that as long as specimens are not damaged, they can be reused from class to class.
As in all Lyle and Louise modules, this kit is geared to high school
and undergraduate courses, and is matched to National Science Education
