Dogs can be trained to detect fresh cadavers but can they detect bodies that have been buried for months or years? Can they detect places where a dead body has rested for a short period of time, such as the trunk of a car, during commission of a crime? Can the odor linger for months or years?
These are the questions addressed by Peter Andrey Smith in a recent article in a special issue of Science devoted to criminal injustice [The Sniff Test]. The article asks whether juries can understand science, You will not be surprised to find out that the answer is "no."
