the police interviewed him and he went on to butcher three more young women before finally being caught in 1981.
While Jacqueline Hill and Barbara Leach, both university students, and Marguerite Wells, a civil servant, were killed at the hands of Sutcliffe, they were equally the victims of John Humble (left), the man who claimed to be the Ripper in his infamous "I'm Jack" tape.
After his arrest, Sutcliffe acknowledged that he had felt confident to continue the killing while the hunt was on for the man with the Geordie accent.
Yesterday, Humble, finally brought to trial a quarter of a century later, was jailed for eight years after admitting intending to pervert the course of justice.
Humble, now 50, delivered his first hoax letter as a prank but, by the time he sent the "I'm Jack" tape, he was revelling in the notoriety. His duping of police made him an accessory to three murders.
He should have been given life. The man who lived the fantasy of being the Ripper should have been forced to face its reality.
