Abstract: Background: The time of death can be determined by identifying the changes in the corpse such as by identifying the flies found in the corpse. In the corpse, fly is an animal that will perch on it, sometimes just a few minutes after death. Fly is one important species in forensic medicine. In corpse, large number of flies can be found which makes it possible to use flies to determine the time of death. The interval of which the flies lay eggs to the developmental phase of the flies can be used in determining the time of death.
