At the Body Farm, the dead speak. This clinical program travels to the world's first open-air crime lab with founder Bill Bass, of The University of Tennessee, for a close-up look at how cadavers decay. As proxies for murder victims, these decomposing bodies are studied in the name of science and the cause of justice. Factors and biological markers that help pinpoint time since death, including wind and weather, insects and carnivores, fire damage, soft tissue leachate, mold, and bacteria, are addressed. Three homicide cases that hinged on data and expertise gained at the Farm are presented, and Ph.D. students are filmed doing field work and body processing.
