Like Pamela Boutflour said, her sister June Bamber told her that Sheila had been behaving strangely and June intended to bring Sheila and the children around for tea on the day of the tragedy so that Pamela could assess her more closely! But it never transpired because by the early hours of the next morning, Sheila had shot and killed four members of her family. Sheila herself remained barely alive until 9.13am, when she was shot dead on the bedroom floor!!!
Actually Mike, I can't find anywhere in her statement where Pam claims June told her that Sheila was "acting strangely". Rather, she is concerned by Sheila's lack of interest in the children and household duties. I get no impression that June suggested that Pam "could assess her more closely", more that she'd like to hear what Pam thought. It certainly didn't appear to be June's intention to "bring Sheila round..............for June to assess her". The invitation to tea appears to have come from Pam. Naturally, I don't believe that Sheila wandered round for several hours -in a semi-dead state- until police shot her, however I MIGHT have been willing to accept, that had she been pointing a gun at them, they shot her in the line of duty...................were it not for the position of the two shots.
The thought has just occurred to me, that you may have inadvertently done exactly what you claim police do, ie you've rewritten a WS using your own words/using words you thought the original words meant. I can see how easy -TEMPTING!- it would be, especially with an inarticulate witness. I'd find it hugely difficult -impossible?- not to correct what they'd said in order to clarify the meaning/make sense of their words.
