Frederick (Fred) West was born in Much Markle, Herefordshire. He was the second youngest of six kids to Daisy Hill and Walter West. Fred often says he was sexually abused in his household. He claimed his father had incestuous relationship with sisters and taught him bestiality (sex with animals).Rosemary (Rose) Letts was born in Devon, England in 1953. Her household was troubled and abusive. Her father, Bill Letts, was a schizophrenic who constantly beat her, her siblings and her mother, Daisy. She was also sexually abused by her father.

Fred and Rose West kidnapped, tortured and raped 11 young girls. Their victims were female and sometimes related to them. The ones who weren't were lured to their house saying that they would be hired as nannies or some job of the sort. When the victim was under their control, they would rape and torture her in wild bondage acts for days and then strangle or suffocate her and bury her on their property. They were caught when police dug up their garden with intentions of finding out the whereabouts of their missing daughter. Fred killed himself after being arrested while Rose was sentenced to life imprisonment.

Safety tips

• If you are going to be a live in nanny be sure to know your "bosses" beforehand. 
• After the first sign of any type of abuse towards your being, leave.
