437 - The Yorkshire Ripper

Peter Sutcliffe, dubbed the Yorkshire Ripper in the press, attacked woman after woman with a hammer and a knife (and sometimes also a screwdriver), primarily in West Yorkshire, England, from 1969 to 1980. Murdering 13 women between 1975 and 1980, he left many other women alive but badly battered and traumatized. The search to find one of England's most heinous serial killers became the largest manhunt in British history.
