Serial Killers - Peter Sutcliffe (The Yorkshire Ripper) - Documentary

Peter William Sutcliffe is a British serial killer known as "The Yorkshire Ripper". In 1981 Sutcliffe was convicted of murdering 13 women and attempting to murder seven others.
Sutcliffe was a regular user of prostitutes in Leeds and Bradford. His obsession with killing streetwalkers seems to have originated with an argument over payment, but he claimed he was being guided by the voice of God. He carried out the murders over a five-year period, during which the public were especially shocked by the murders of some pedestrians who were not prostitutes.
