The New Detectives

A motel clerk is found dead on the lobby floor. Police arrive to find a bloody palm print and most of a fingerprint. They're finally led to an ex-employee. Human remains are found in a garbage bag. Reverse DNA testing proves the body was in fact that of a man's missing wife. A toxicologist is brought in to prove the cause of the woman's death and her husband is charged with her murder. In both cases the killer tried to hide the actual cause of death but forensic science can't be fooled.
