Fred West
Between 1967 and 1987, West – alone and later with his second wife, serial killer Rosemary West – tortured and raped young women and girls, murdering at least 12, including their own family members. Fred killed at least two people before collaborating with Rose, while Rose murdered Fred's stepdaughter (his first wife's biological daughter) when he was in prison for theft. Most of the murders occurred between May 1973 and August 1979, in their homes at 25 Midland Road and 25 Cromwell Street in Gloucester. Many bodies were buried at or near these homes and sometimes even in the walls of their home.
