National Institute of Justice Examines Research to More Accurately Determine Time of Death
WASHINGTON — The Office of Justice Programs’ National Institute of Justice today published an article discussing how NIJ-funded researchers are using microbes involved in human decomposition to more accurately determine how long a body has been deceased.
Using the progression of insect populations during the first two weeks of decomposition has long served as an indicator, or “clock,” for determining a time of death. But in recent years several NIJ-supported researchers have been trying to extend the clock to cover longer time periods and serve as a more precise measurement by focusing on the microbes that consume a body after death.
Unlike insects, trillions of microbes, such as viruses, bacteria and fungi, live in our bodies. While they are not harmful to living persons, at the moment of death, microbes inside the body and from the surrounding environment start breaking down organs and other tissue. Knowing which microbes appear and when, as decomposition progresses, is the basis for the postmortem microbial clock.
