The temporary landlord and his partner had done twelve weeks' training at the PoW with MH, the permanent landlord, earlier that year. They were brought back to fill in expressly because, as he told DV,
‘When I was on holiday, I always insisted that the people I’d trained at my pub do my relief work. Those were the ones that ran my pub when I wasn’t there. Because they knew how I ran it. They knew the customers, the staff...'
So while KH had only just arrived back, it is not correct that he hardly knew the pub. Having lived in the area for three recent months he knew it quite well. SJL was likely a regular, so KH may have known her by sight if not name from his previous stint there.
I say 'likely' a regular because the PoW was en route to her parents' house and was the nearest pub. According to NB, the landlord before MH, it had been refurbished in late 1984. So when SJL arrived in the area, it would still have been quite spruce. AL initially claimed her stuff was lost there on the Friday night, while later claiming never to have been there at all, so this says she did at least occasionally go. MH on the other hand did not recognise her as a regular.
It is hence possible but not proven that KH had met SJL before 28/7.
This is not enough to hang an accusation on. The main issue is why did they get the stocktake done by 12 if they didn't intend to open normally at lunchtime; and if they were open, when exactly was KH's opportunity to kill and hide her? Even if the pub was empty of punters it wasn't completely empty - even when shut, pubs never are. There is food being prepared, areas to clean, and so on - all this happens while closed.
There are some really odd things about the pub aspect of this but it's a big reach to make it a crime scene.
