Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How can a blowfly help an investigation?
A
Helps investigators determine time of death.
B
Helps investigators determine how a person was killed.
C
Helps investigators determine what the person ate at his/her last meal.
D
None of the above
Explanation: 

Detailed explanation-1: -“In cases where a body is colonized by larvae in suboptimal temperature conditions, the presence of blowflies provides evidence that the body was moved after death.”

Detailed explanation-2: -Blowflies, however, lay eggs within minutes of someone dying and so investigators can use the growth timeline of blowfly maggots to find out exactly when a person died. In some deaths, establishing the time a person died is extremely important.

Detailed explanation-3: -By using blowflies and sometimes other insects, forensic entomologists can provide an estimated window of time in which someone is likely to have died. This is calculated by estimating the amount of time since eggs were first laid, which approximates (sometimes quite closely) the time of death.

Detailed explanation-4: -The emerging larvae, maggots, will then feed on the decomposing tissue and forensic investigators can determine the time of death by analyzing the maggot species present and what life stage they are in.

Detailed explanation-5: -Blow flies and flesh flies are the most useful crime scene insects for determining the postmortem interval, or time of death. Through laboratory studies, scientists have established the developmental rates of necrophagous species, based on constant temperatures in a laboratory environment.
