Final answer:
Forensic scientists may use forensic entomology to estimate the PMI, detect drugs in maggot infested bodies, and determine the location of the body at the time of death.
Step-by-step explanation:
Forensic entomology is the use of insects for forensic purposes. Forensic scientists may use forensic entomology to estimate the duration of the post-mortem range (PMI), detect drugs of abuse in maggot infested bodies, and detect the location of the body at the time of death. However, forensic entomology is not typically used to collect DNA material left on the corpse in cases of sexual assault or to detect volatile hydrocarbons in fire deaths.
