Fred & Rose West
They were the typical family next door, or at least they appeared to be. But 1994 witnessed the slow peeling away of the layers of secrets hidden in the ordinary house at 25 Cromwell Street, now known as the Gloucester House of Horrors. Rose was running a thriving prostitution business, bearing illegitimate, mixed race children one after another, while Fred lured young women to stay at the house. While that may have provoked scandal, police discovered that Fred & Rose turned their children and guests into sex slaves and murdered them when they tried to escape.
