Fred & Rosemary West were both raised in homes of incest, which they carried on with their own 10 children. They killed at least 9 young women, along with their daughter, Heather, and their step-daughter, Charmaine. When CPS showed up to remove the remaining 8 children, the kids revealed that they "had to behave" or else they would "end up under the patio, like Heather." In 1995, Fred confessed to 12 murders, then hanged himself with a sheet in his cell. Rosemary was given a life sentence.
