Bug Expert Determines Time of Death Using Insects
One common task for forensic scientists at crime scenes is to determine the time of death. In cases where it has been more than four days, traditional methods like examining the body become less accurate. That's where bug experts come in. By studying the insects that colonize a corpse, entomologists can determine how long the body has had fly activity, which provides an estimate of the time of death. Different species of flies appear on the body at different times, allowing for more precise estimates. However, external factors like weather and the presence of cocaine in the body can affect the accuracy of the estimate.
