A Tennessee forest that was nicknamed 'Body Farm' contains decomposing corpses for CSI students to learn from.
At first glance, it appears to be a sort of dumping ground of a serial killer, but the bodies left scattered in the isolated forest in the hills of Knoxville, Tennessee, has been put there on purpose to help forensic experts to better understand the decomposition process.
The ‘Body Farm’ research laboratory in Knoxville, offers a unique opportunity for teams to study murder scenes in the most realistic environment possible.
At any given time, there are between 150 and 190 bodies strewn among the trees and leaves, all donated by people hoping to bring murderers to justice from beyond the grave.
"We help the police find out what happened to someone, said Dr. Dawnie Steadman, University Center of Tennessee Forensic Anthropology.
The bodies are placed in a variety of areas to imitate crime scenes. Some are buried in shallow graves, inside vehicles or even in a noose, while being watched closely, while other are left for wildlife to feed on.
The researchers then let nature take its course, collecting vital clues that helps them solve mysteries. Since the 1980s, the facility is regularly visited by police, prosecutors and judges.Mobile video not loading? Click here to view
