Forensic Files

Caren Campano disappears and the explanation of her husband Chris doesn't hold up. Police find a large stain on the Campano's bedroom carpet. They perform an eerie chemical test 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, even though the body wasn't found until a year later.
