Tutor description

It is August 19, 2013. A body was discovered in Phoenix, AZ. At the same time, a body was discovered in Grand Forks, ND. Both of the bodies are in stages of advanced decomposition. • What factors must a forensic entomologist consider when determining postmortem interval? • Could both of the victims have been killed and their bodies left at approximately the same time? Why or why not? • Based on the advanced stages of decomposition, what are methods that could be used to aid in determining the identity of the remains? • In your opinion, is the use of insects to determine the postmortem interval realistic, or are there better means to determine this? Explain. • Besides a forensic entomologist, what other forensic specialists would be beneficial to have at the scene? Explain. • In your Discussion Board responses to other students, be sure to address their points on the above topics.

CRJS470-DB1NameClassDateProfessorCRJS470-DB1 Forensic entomology is forensic science methods were the life cycle of bugs is used to determine the rate of decomposition of a body (Bullington, 2011). The insects that are located on a body when it is discovered can provide information to the forensic specialist on the time of the death of the victim which is crucial information in a criminal investigation. While the two bodies located in Phoenix, Arizona and Grand Forks, Nevada was located at the same time only in two different places does not suggest that the rate of decomposition for the two bodies will be the same. The role of the forensic entomologist is to study the different stages of aging in the bug life to make a determination of when death occurred (Byrd, 2010). The post mortem interval is the stage of decomposition of the body. The factors that would need to be considered concerning the post mortem intervals is the growth span or age of the insects discovered in the body. For example if a fly laid eggs in the body but the eggs were still in the larvae stage the PMI would be shorter than if the eggs had hatched and become full grown flies. The length of time the body has been exposed to insects is the way the PMI will be determined. While it is possible that both bodies were dumped at the same time and it is also possible they were killed at the same time but the rate of decomposition will be different based on the environment i
