Frederick Walter Stephen West, commonly known as Fred West, was an English serial killer who committed more than 12 murders of young women and teenagers in Gloucestershire. Many of these murders reflected Frederick’s sexual depravity; there was a pattern of rape, bondage, and torture before the killings. His second wife Rosemary West had assisted him in many of the murders and sexual assaults. Most of the bodies were buried in the cellar or garden of his house at Cromwell Street in Gloucester, which was later called the "House of Horrors". Fred also had sexual interest in his own daughters, and tortured and killed two of them, helped by his wife. The duo was arrested several times, but was acquitted due to lack of evidence. Following an anonymous call from a lady who informed the police about the sexual abuse going on in the West household, Detective Constable Hazel Savage led a search at Cromwell Street in August 1992, and found clear evidence of child abuse. Fred and Rose were arrested but were acquitted once again. Finally, they were arrested and charged in 1994. While Fred hung himself to death in the prison, his wife was sentenced to life term with a whole life order.
