If JC had been stalking her, whether as a stranger or an ex, he would have delved & probed into every minutia of her movements/life.
If it was JC who stole her cheque book/diary etc, it was also him who placed it on the pub steps after going through everything - knowing 99% the pub LL would contact Suzy to say he'd found them, and she'd arrange to collect them on the Monday.
After abducting Suzy he would have told her he knew she'd lost them, and if there was anything sensitive in her diary, he'd have used that information to humiliate/intimidate her. It's possible that Suzy pleaded with him and even told him she needed to be at the pub at 6pm to collect them, and to give himself added power he told her if she could prove that to him he'd drive her there himself. Of course, he had no intention of doing that, but all the cat/mouse game playing would've excited him. Suzy would have clutched at any straw to escape, and if he did come up with such a ludicrous promise, she'd have agreed in her desperation even if she wasn't sure he would. She'd have done absolutely anything to get away; hence her phoning the pub leaving a message for herself. He possibly swung from aggressive to charming, as he did with his ex-girlfriend who he'd raped, and in Suzy's fear she'd have been completely confused and agreed to anything
Also, at that time no-one except Suzy & the pub LL & wife knew she was going back to the pub. So that call had to of been Suzy herself. The following call from the bogus policeman would have been Mr Kipper (JC, IMO), and he probably rang to see if the police had yet been alerted. Maybe he was considering driving Suzy's car somewhere (with or without her) but decided against it despite Suzy not seeming to have been reported missing.The clock was ticking and it was risky.
Re: the scrap of paper - the pub LL was absolutely adamant he'd given it to the officers. The officers insisted he didn't. I can't see why the LL would lie about that, he wasn't a suspect, and as he'd brought himself to the attention of the police they would have been bound to have checked him, and his story out. It's possible that none of the three were lying and they were all genuinely mistaken, but it is strange...I suppose there is the possibility despite all the compelling circumstantial evidence pointing to JC, that the LL could be Mr Kipper. But his pub was a good 10 minutes away (and that's without traffic)....Suzy's car was at Stevenage Road at 12:45...so she couldn't have driven to the pub and back within five minutes. And I can't imagine the LL agreeing/arranging to drive through heavy traffic (it's always heavy round there) when Suzy had told his wife she'd collect her diary etc later. And if the LL did have some kind of fixation with Suzy he'd have had plenty of better timings in which to abduct her, especially as she lived round the corner to his pub
As for DV saying everyone's missed what's blindingly obvious, if it's that obvious why did he spend three years investigating everything? He'd have cracked it overnight, and surely one of the investigating team who had access to every file on Suzy's case would have spotted the "blindingly obvious" over 30 years ago? It could be that after DV's three year investigation all the pieces of the puzzle clicked into place and it suddenly became obvious to him, but I can't see how he can categorically say he knows who the murderer is when all his investigating has been through interviews and going over old statements etc. He hasn't got any DNA evidence proving who the murderer is - he doesn't even know where Suzy's body is - so how could he know for sure who killed her?
Someone, somewhere knows what happened to Suzy, and my bet is that it's JC. He lived in the vicinity, he was a thief, abductor, rapist and murderer. Almost every witness who saw Mr Kipper described him as how JC looked and dressed - even down to his build, colouring, eyes, demeanour...witnesses mentioned a BMW which JC had access to...Kipper was his nickname in prison...he was attracted to career type women who looked like Suzy...he would have had an interest in an estate agent to help him on the property ladder...he flared up & angered easily when rejected...he used his looks and educated voice to charm...
And to add to the mix, he was allegedly involved with seedy characters on the fringes of mortgage fraud, so Suzy, I suspect in a slightly naive way could have possibly been taken in very easily by him - at first. That's supposing they had once dated briefly...no-one really seems to know.
