The Medical Detectives: The House That Roared

Caren Campano disappears, and her husband's story doesn't hold up. Police find a large stain on the Campanos' bedroom carpet. They use a chemical called luminol that reveals a room spattered with blood which, when cleaned off, could not be seen by the naked eye. Complex 'reverse paternity' tests of Caren's relatives match her blood type to the blood on the carpet. The evidence convicts Chris Campano of murder. The body isn't found until a year later
