Frederick Walter Stephen West (29 September 1941 – 1 January 1995), was a British serial killer. Between 1967 and 1987, he alone, and later, he and his wife Rosemary, tortured, raped and murdered at least 11 young women and girls, many at the couple's homes. Rosemary West also murdered Fred's stepdaughter (his first wife's biological daughter) Charmaine, while he was serving a prison sentence for theft. The majority of the murders occurred between May 1973 and September 1979 at their home in 25 Cromwell Street, Gloucester. The house was demolished in 1996 and the space converted into a landscaped footpath connecting Cromwell Street to St. Michaels Square.
