During the period about thirty years ago, a dreaded psychopathic serial killer was on the loose. He was a truck driver, picking up women who service truck drivers. Another socio-path made up audio tapes taunting the police. He had a strong Geordie accent. The police had already tabbed the real killer, but were not ready to arrest him. Thinking the accent was that of a Newcastle native, they dropped the tail on Sutcliffe. The real killer was from Yorkshire, not County Durham. He later murdered four more unfortunate women, while the police searched elsewhere.
An expert then identified the miscreant who so deluded the authorities. He identified the voice down to an actual section. This of about three streets in Newcastle. The police then went door to door, they found there was a man who professed hatred for the police. The police arrested the hoaxer and he got 7 years imprisonment for impeding justice. Let out sooner than that however.
Audio hoaxer lived at Castleton,Sunderland. It is in North East England, as is Newcastle. I am glad to be able to avoid Geordie invective, should I have been over there. I am sure I read elsewhere -probably in the UK tabloids the hoaxer was from Newcastle.
