S03:E02 - Bodies of Evidence

It is difficult to convict a murderer if the body can't be found. But forensic science is finding ways to do it. Devious killers can think up many was to dispose of their victim's remains, but they are often no matches for creative and devoted investigators. A speck of blood, a piece of a fingernail or a strand of hair may now be enough evidence to prove a murder and capture a killer.
