The House that Roared refers to episode 3 of the first season of the television series Forensic Files which was broadcast for the first time on October 10, 1996.

Plot summary
In 1992, Caren Campano disappears from her Oklahoma City, Oklahoma home, 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.
