Yes sportsergirl he was clearly disturbed. I do monitor prisoner releases and I have nothing on record saying he has been released. He would be 83 now. Having been 49 when he committed the murder it would be strange if this was his only victim but it was said that he had been having psychiatric treatment since the death of his mother and maybe that was the trigger.
Remember this on crimewatch. There are many unsolved prostitute murders in the midlands. There was suggestions of a midlands ripper and Alan Kyte & Christopher Halliwell have been suggested for Yvonne's murder. Also Gordon Wardell is suspected to be behind many unsolved attacks and murders of midlands prostitutes. I could see Jones killing Yvonne. He was unable to consumate a relationship with a woman and could have snapped if mocked. He was also big built and capable of causing death or serious injury easily.Not sure on this but I'm sure there was mention of Jones taking obscene photos of children
