Microorganisms at the crime scene reveal the time of death - Biotech. Around 20 species of microorganisms have been discovered.
They are fungi and bacteria that appear on the corpse and decompose it with well-defined times. This is demonstrated by an American study funded by the National Institute of Justice (Nij) of the United States. The researchers monitored the decomposition process of 36 corpses donated to science and placed in three different forensic anthropology facilities in Colorado, Tennessee and Texas. The study was conducted outdoors in different environmental and climatic conditions, in the four seasons.
