Corpse: Nature, Forensics, and the Struggle to Pinpoint Time of Death

When detectives come upon a murder victim, there's one thing they want to know above all else: When did the victim die? The answer can narrow a group of suspects, make or break an alibi-even assign a name to an unidentified body. But outside the fictional world of murder mysteries, time-of-death determinations have remained infamously elusive, bedeviling forensic pathologists throughout history. Scientists are doing their best to right this situation, using DNA testing and other high-tech investigative methods. But as Jessica Snyder Sachs argues in Corpse, this is one case in which nature might just trump technology: plants, chemicals, and insects found near the body are turning out to be the fiercest weapons in our crime-fighting arsenal.
