Peter William Sutcliffe (born 2 June 1946) is a British serial killer who was dubbed "The Yorkshire Ripper". In 1981 Sutcliffe was convicted of murdering 13 women and attacking seven others. He is currently serving 20 sentences of life imprisonment in Broadmoor Hospital. After his conviction, Sutcliffe began using his mother's maiden name and became known as Peter William Coonan. The High Court dismissed an appeal in 2010, confirming that he would serve a whole life tariff and would never be released from imprisonment.
