Final answer:
A forensic entomologist is a professional who uses the study of insects, particularly in the decomposition stage of dead bodies, to give insights on the time of death in legal investigations. Their expertise is a crucial link in the forensic science chain, aiding in the accurate determination of the sequence of events in a crime.
Step-by-step explanation:
A forensic entomologist applies the study of insects to legal cases. This field is essential in determining the time of death in homicide investigations by examining the stages and types of insects, such as maggots, present on decaying flesh. Work in this field often involves collaboration with other forensic experts, particularly in settings like the U.S. Army Criminal Investigation Laboratory, where DNA extraction and analysis are crucial components of criminal cases.
Forensic entomology is a specialized area of study that marries the expertise of an entomologist with forensic science to aid in solving crimes. An understanding of insect life cycles and behavior is key to providing valuable information in legal investigations, especially regarding the post-mortem interval or PMI, which can be crucial in a court of law.
