Medical Detectives

Five-year-old Melissa Brannen disappeared from a Christmas party in Fairfax, VA, leaving little evidence and no witnesses. Black rabbit hairs found in a Caleb Hughes' car along with unique blue fibres lead police to solve this mysterious murder and arrest the perpetrator.

Police find a severed leg in a rubbish bin but are unable to use conventional methods of victim identification. Toxicology and DNA tests may give police a name.
