Yorkshire Ripper

Peter William Sutcliffe, also known as Peter Coonan, was an English serial killer who was convicted of murdering thirteen women and attempting to murder seven others between 1975 and 1980. Press reports dubbed him the Yorkshire Ripper, an allusion to the Victorian serial killer Jack the Ripper. Sutcliffe was sentenced to twenty concurrent sentences of life imprisonment, which were converted to a whole life order in 2010. Two of his murders took place in Manchester; all the others took place in West Yorkshire. Criminal psychologist David Holmes characterised Sutcliffe as being an "extremely callous, sexually sadistic serial killer."
