Convicted murderer George Naylor - serving a life prison sentence for strangling a teen-age girl - is going back to Court to claim his innocence for the third time.Naylor, now 58, was twice convicted by juries of murdering 18-year-old prosti-tute Maureen Stepan at her flat in Washington Street, Girling-ton, Bradford, on June 9, 1995.Naylor, of Alva Terrace, Ship-ley, was sentenced to life imprisonment in February 1997 after he was found guilty by a majority verdict of Maureen's murder.But his lawyers imme-diately launched an appeal, on the grounds that the jury had been told he had a previous conviction for manslaughter. He was granted a retrial.Two years later he was found guilty for the second time, again by a majority verdict.Naylor was jailed for life and the judge rec-ommended he should not be re-leased for at least 20 years.But in December 1999, Naylor was granted leave to appeal against the conviction by the Lord Chief Justice of the Court of Appeal.Legal wranglings and dem-ands by Naylor for tran-scripts of court proceedings de-layed the hearing.But now it is set to go ahead at the Court of Appeal in London later this month.A spokesman for the Crown Prosecution Service confirmed a date had been set for the hearing at the end of this month.She said it was ex-pected to last at least one day and Naylor would be represent-ing himself in court. Detective Superintendent Allan Doherty, one of the senior officers on the investigation, will be travelling to London to attend the ap-peal.Naylor's trial was told he picked up Maureen in Thorn-ton Road, Listerhills, Bradford, and took her to her home where he strangled her with her tights and his arms. He then burned her mouth with a cigarette and mutilated her body.At the end of the trial the jury was told of previous con-victions, including a 15-year jail sentence for the robbery and rape of a pensioner in Bradford.Eight weeks after his release he killed another pros-titute, 22-year-old Deborah Ker-shaw, in Bradford's red light district in 1985. He was given a life sentence for manslaughter which was later slashed to 11 years on appeal.When the ap-peal on the Maureen Stepan murder was announced four years ago, Naylor's solicitor, Bill Hicks, claimed that a prime suspect for the murder was not properly investigated by police.
